Energy Department Offers $13 Million to Advance Ocean Energy Technologies

 

The Energy Department on April 30 announced up to $13 million in funding to develop and test advanced components and technologies to boost the performance of marine and hydrokinetic (MHK) energy systems. The Energy Department plans to select up to 10 awards aimed at developing advanced controls, power systems, and device structures specifically for MHK applications, which harness energy from waves, tides, or currents.
Through the new funding opportunity, the Energy Department intends to support projects that increase the power-to-weight ratio of MHK devices or improve system reliability through investment in three component technologies. The Department will select up to six projects to develop advanced control systems, including software or hardware, and perform numerical modeling or testing to assess performance improvements; up to two awards will be selected that focus on developing lighter, more compact, and more efficient power take-offs (PTOs) to increase system and component reliability and modularity and to make PTOs longer-lasting and easier to repair; and up to two projects will develop and test an advanced device structure that minimizes the loads transmitted to other components and increases the device’s ability to withstand extreme conditions. See the funding opportunity announcement at the Water Power Program Financial Opportunities Webpage.
The Energy Department also launched a new Energy 101 video on a range of innovative MHK technologies and the Department’s research and development efforts to improve performance and lower costs. Additional information on these efforts is available through Open Energy Information’s new Water Power Gateway. See the Progress Alert and the Water Power Gateway.
 

New Battery Design Could Help Solar and Wind Power the Grid

 

Researchers from the Energy Department's SLAC National Accelerator Laboratory and Stanford University have designed a low-cost, long-life “flow” battery that could enable solar and wind energy to become major suppliers to the electrical grid. The research is a product of the new Joint Center for Energy Storage Research (JCESR), an Energy Department Energy Innovation Hub. Established last November and led by Argonne National Laboratory with SLAC as a major partner, JCESR is one of five such Hubs created by the Energy Department to accelerate energy research.
While solar and wind power make a substantial contribution to the nation’s energy supply, they also create significant power fluctuations, which can sometimes exceed the tolerances of the electrical grid. “Flow” batteries can smooth those fluctuations. Typically, flow batteries pump two different liquids through an interaction chamber where dissolved molecules undergo chemical reactions that store or give up energy, and have a membrane that only allows ions not involved in reactions to pass between the liquids while keeping the active ions physically separated. The new flow battery uses a simplified design without a membrane, and is a less expensive design compared to other batteries, which may improve its scalability and cost-effectiveness. In laboratory tests, it also demonstrated excellent energy storage performance through the equivalent of more than five and a half years of daily charge and discharge cycles. See the Energy Department press release and the JCESR website.
 

Report Assesses Potential U.S. Hydropower Upgrades

 

The Energy Department on April 22 announced a new study outlining key improvements that can be made to hydropower production in the United States to provide more efficient and cost-effective electricity to homes and businesses. Developed with funding from the Energy Department, the Electric Power Research Institute's (EPRI) report, "Quantifying the Value of Hydropower in the Electric Grid," identifies and assesses the quantifiable benefits from potential improvements. The report cites potential upgrades such as installing turbines that can operate with lower water levels, utilizing new power plant designs that can increase revenue and efficiency, and monetizing the services hydropower provides to the nation's electric grid.
Hydropower supplies about 7% of U.S. electricity generation and is currently the nation's largest source of renewable electricity. Hydropower is widely valued for the ancillary services, or flexibility, it provides to the power grid—allowing storage capabilities, enabling fast stops and starts, and responding rapidly to imbalances of supply and demand to maintain power system stability. For example, pumped storage hydropower plants can pump water uphill when electricity supply exceeds demand, such as during nighttime hours or times when renewable energy sources are generating more power than consumers are using. This ability to store energy until it is needed—and to absorb excess renewable energy generation—lowers electricity prices and enables the generation of more renewable electricity.
The researchers looked at improvements that could boost the efficiency and output of hydropower plants and at pumped storage hydropower systems, particularly in their potential to be integrated with variable renewable sources such as wind and solar power. According to the report, hydropower plants could see their largest revenue and efficiency increases by deploying new hydropower technologies, making operational improvements, utilizing hydropower's flexibility more in grid resource planning, and monetizing the energy storage capability of pumped storage. Among the key findings from the report: relying more heavily on hydropower to address changes in electricity supply and demand could provide more flexible reserve power options and reduce wear and tear on conventional thermal-generating equipment; and expanding the effective operating range of hydropower units by reducing the minimum amount of water needed to use the turbines stably can increase the production value of plants by 60%. EPRI also published nine accompanying case studies and supplemental reports that discuss the elements covered in the final report in greater detail. See the Energy Department Progress Alert and the complete report PDF.
 

EIA Opens New State Energy Portal Online for Consumers

 

The U.S. Energy Information Administration (EIA) announced on April 11 that it has launched a publicly available, comprehensive online view of the U.S. government's national and state energy data and information. The agency designed the new online portal with a range of users in mind, including policy makers, energy analysts, and the general public, who want to locate and compare state energy data and rankings and customize their own maps and charts, using an assortment of interactive tools.
Users can view an array of energy facilities and resources, including information about renewable resource potential for wind, solar, biomass, and geothermal energy. In addition to customizable maps, the portal summarizes each state's ranking of its energy production, consumption, prices, and more. The state energy portal adds a unique visual dimension to each state's energy resources and infrastructure. See the EIA press release and the state energy profile website.

A Renewable Boost for Natural Gas

 

The race to transition to cleaner, greener natural gas power plants is getting a boost from an unlikely source—solar energy. A new system developed by the Energy Department's Pacific Northwest National Laboratory (PNNL) converts natural gas and sunlight into a more energy-rich fuel called syngas, which will allow hybrid solar-gas power plants to use about 20% less natural gas to produce the same amount of electricity while also lowering the plant's greenhouse gas emissions.
The system works through concentrating solar power, which uses a reflecting surface to concentrate the sun's rays like a magnifying glass. In the case of the new system from PNNL, a mirrored parabolic dish directs sunbeams to a central point, where a device absorbs the solar heat to make syngas.
The four-foot-long, two-foot-wide device contains a chemical reactor and several heat exchangers. The concentrated sunlight heats up the natural gas flowing through the reactor's channels, where a catalyst helps turn the natural gas into syngas. The heat exchangers recycle leftover heat from the chemical reaction gas, increasing the efficiency of the system. In fact, tests on an early prototype of the device demonstrated that more than 60% of the sunlight hitting the parabolic dish was converted into chemical energy contained in the syngas. For the complete story, see the Energy Blog.

Energy Department Announces Projects to Develop Innovative, Advanced Drop-in Biofuels

 

The Energy Department on April 22 announced nearly $18 million in four innovative pilot-scale biorefineries that will test renewable biofuels as a domestic alternative to power cars, trucks, and planes, and that also meet military specifications for jet fuel and shipboard diesel. These biorefineries will be in in California, Iowa, and Washington.
The projects selected for funding include Frontline Bioenergy of Ames, Iowa, which will use an innovative new pilot scale reactor and new gas conditioning processes to produce biofuel from woody biomass, municipal solid waste, and refuse; Cobalt Technologies of Mountain View, California, which will operate a pilot-scale integrated biorefinery to convert switchgrass to bio-jet fuel; Mercurius Biorefining of Ferndale, Washington, which will build and operate a pilot plant that uses an innovative process that converts cellulosic biomass into bio-jet fuel and other chemicals; and BioProcess Algae of Shenandoah, Iowa, which will evaluate an innovative algal growth platform to produce hydrocarbon fuels meeting military specifications using renewable carbon dioxide, lignocellulosic sugars, and waste heat.
The pilot-scale biorefinery projects selected will use a variety of non-food biomass feedstocks, waste-based materials, and algae in innovative conversion processes to produce biofuels that meet military specifications for jet fuel and diesel. The projects will demonstrate technologies to cost-effectively convert biomass into advanced drop-in biofuels and assist these organizations to scale up the processes to commercial levels. Recipients are required to contribute a minimum of 50% matching funds for these projects. See the Energy Department press release.
 

Energy Department Highlights Nissan’s Better Plants Challenge Project

 

The Energy Department on April 17 recognized Nissan’s participation in the Better Buildings, Better Plants Challenge and its showcase project at the company’s new energy-efficient paint plant in Smyrna, Tennessee. The 250,000-square-foot Smyrna facility, which opened in January, is expected to cut energy use by almost a third compared to its predecessor.
As a partner in the Better Buildings, Better Plants Challenge, Nissan North America has committed to reducing energy use in its three U.S. plants by 25% by 2020, affecting 12 million square feet of plant space. Better Buildings, Better Plants Challenge participating organizations receive technical assistance from the Energy Department and share best practices on industrial energy efficiency with other Challenge partners.
Each year, the United States spends about $200 billion just to power commercial buildings and another $200 billion to power industrial facilities. Together, commercial and industrial buildings account for roughly half of the nation’s energy use and more than 40% of U.S. carbon emissions. The Better Buildings, Better Plants Challenge serves as the industrial component of President Obama’s broader Better Buildings Challenge, which was launched in December 2011 to help America’s commercial and industrial buildings become at least 20% more efficient over the next decade. See the Energy Department press release and the Better Buildings, Better Plants Challenge website.
 

EIA: 2012 Home Energy Bills Lowest Percentage in 10 Years

 

U.S. consumers spent 2.7% of their household income on home energy bills last year, which was the lowest percentage in 10 years, according to a U.S. Energy Information Administration (EIA) analysis released on April 18. Also, aggregate home energy expenditures by U.S. households fell $12 billion in 2012 from the 2011 level. Warmer weather contributed to lower energy consumption in 2012, and because household energy expenditures reflect both prices and consumption, these changes resulted in lower household energy expenditures.
On average, households spent $1,945 on heating, cooling, appliances, electronics, and lighting in 2012. This total includes home use of electricity, natural gas, fuel oil, propane, kerosene, wood, and coal, but excludes fuels used for transportation. It also excludes other household utilities such as water and telephone services. Using EIA projections for 2012 based on household data from the U.S. Census Bureau through 2010, $1,945 is the lowest level since 2002. The percentage of household income spent on home energy bills peaked at 4.3% in 1982 and steadily declined until it reached its lowest level since 1973—2.4% in 1999. See the EIA's Today in Energy.
 

Walmart Announces New Goals for Energy Efficiency and Renewable Energy

 

Walmart on April 15 announced the company’s next step on the path to achieving its goal of being 100% supplied by renewable energy. The company committed to achieving the production or procurement of 7 billion kilowatt-hours of renewable energy globally every year by the end of 2020. That would mark a 600% increase over its 2010 levels. The Bentonville, Arkansas-based retailer will also seek to reduce the energy intensity required to power the company's buildings during the same period by 20%.
Walmart expects its six-fold increase in utilizing renewable energy projects to be equal to eliminating the need for roughly two U.S. fossil fuel power plants. Based on external estimates of projected energy costs and other factors, the two new commitments are anticipated to generate more than $1 billion annually in energy savings once fully implemented. The company also expects to avoid 9 million metric tons of greenhouse gas emissions, the equivalent of taking 1.5 million cars off the road.
In the United States alone, Walmart plans to install solar power on at least 1,000 of its rooftops and facilities by 2020, an increase from just over 200 solar projects currently in operation or under development. According to the Solar Energy Industry Association, the company has more solar power capacity and number of systems than any other company in America. It has also been cited by the U.S. Environmental Protection Agency as America’s leading user of onsite renewables, using more onsite renewable power than any other company in the United States. In addition to onsite solar, the company will continue to develop projects in wind, fuel cells, and other technologies. It will also procure offsite renewable energy from utility-scale projects, such as large wind, micro-hydro, and geothermal projects. See the Walmart press release.

On the Path to Low Cost Renewable Fuels, an Important Breakthrough

 

by Leslie Pezzullo, Technology Manager, Bioenergy Technologies Office
America’s homegrown fuel resources—from wood chips to the leaves and stalks of corn plants—are plentiful. Research finds that these resources could produce enough clean, renewable fuel to replace about 30% of the nation’s current petroleum consumption. Still, on the path to creating a strong, thriving biofuels industry, there are challenges we continue to address. That’s why the Energy Department is working with researchers, industry, and other partners to increase the reliability and cost-effectiveness of renewable fuel production.
The good news is we are making progress—particularly when it comes to cellulosic ethanol. For the uninitiated, cellulosic ethanol is fuel produced from the inedible, organic material abundant in agricultural waste—including grasses, farm waste, and virtually every type of plant. While cellulosic ethanol represents a huge opportunity for the renewable fuels industry, the high costs and inefficiencies associated with the technology are barriers to its commercialization. However, with major technology milestones met by researchers at our national labs and industry partners, that’s all starting to change.
Last fall, scientists at the National Renewable Energy Laboratory (NREL) successfully demonstrated the technical advances needed to produce cellulosic ethanol cost competitively at $2.15 per gallon—a process that was modeled at $9 per gallon just a decade ago.

SUPEUS – studenti za budućnost





U organizaciji Hrvatskog Centra Obnovljivih Izvora Energije (HCOIE) nastavljeno je predstavljanje hrvatskih visokotehnoloških tvrtki, udruga i poduzetnika na europskim i svjetskim portalima kojima je zajednički predznak energetika, obnovljivi izvori energije i očuvanje okoliša.
 „Želim naglasiti da će hrvatske tvrtke, udruge i poduzetnici ovdje biti promovirane ne samo da bi prodavali svoje proizvode nego i da bi svoje znanje razvoja informacijskih i energetskih tehnologija podijelile s sličnim svjetskim tvrtkama, poduzetnicima iz razvijenih nacija kojima se Republika Hrvatska prilagođava i politički i gospodarski. Nadam se da će naše prezentacije hrvatskih tvrtki i poduzetnika dovesti do suradnje između država, kompanija i poduzetnika do razine koja nije samo prijateljstvo nego i partnerstvo", istaknuo je Željko Serdar , predsjednik Hrvatskog Centra Obnovljivih Izvora Energije.


SUPEUS – studenti za budućnost



SUPEUS - Studentska udruga za promicanje energetske učinkovitosti i savjetovanje predstavlja ambiciozni tim studenata tehničkih i prirodoslovnih fakulteta Sveučilišta u Zagrebu čija je glavna zanimacija promoviranje energetske učinkovitosti, održive gradnje i obnovljivih izvora energije, a glavna djelatnost su seminari, radionice i ostali informativno edukacijski projekti kojima nastojimo povezati studente, tvrtke i fakultete. Udruga trenutno broji 25 redovnih članova, 29 članova pripravnika, 2 alumni člana i 8 počasnih članova.  Članovi su studenti  Arhitektonskog fakulteta, Fakulteta elektrotehnike i računarstva, Fakulteta strojarstva i brodogradnje te Građevinskog fakulteta, studenti Prirodoslovno matematičkog fakulteta – Znanosti o okolišu, Ekonomskog fakulteta, Fakulteta kemijskog inženjerstva i tehnologije i Rudarsko naftno geološkog fakulteta. Hrvoja Turibaka, Josipa Markežića, Marka Miškovića i Hrvoja Turkovića na osnivanje SUPEUS-a potaknulo je višegodišnje aktivno praćenje i sudjelovanje u projektima energetske učinkovitosti, obnovljivih izvora energije i održive gradnje.. Vođeni željom promoviranja održivosti među studentima, odlučili su osnovati Udrugu. Prvi sastanak osnivača održan je 1. ožujka 2011. godine na Fakultetu elektrotehnike i računarstva. Dana 14. ožujka 2011. održana je i osnivačka skupština na kojoj je donesena službena odluka o osnivanju Udruge te je donesen statut. Udruga je registrirana pri Gradskom uredu 6. svibnja 2011., a službeni početak rada Udruge je 27. rujna 2011., kada je rad Udruge službeno predstavljen. Tijekom godinu i pol rada, članovi Udruge uspješno su pripremili i odradili pet projekata, a svaki je naišao na odobravanje studenata, profesora, ali i tvrtki. Uz to, članovi Udruge redovito svoje znanje proširuju i nadopunjuju na internim seminarima. Članovi SUPEUS-a redovito prolaze i službene edukacije u području savjetovanja o energetskoj učinkovitosti, obnovljivim izvorima energije i održivoj gradnji, a priliku za dokazivanjem imaju kroz odjel savjetovanja. Profesionalnost, znanje i konstantna želja za dokazivanjem glavne su odlike svakog člana SUPEUS-a. SUPEUS je u 2012. godini postao partnerski član Savjeta za zelenu gradnju u Hrvatskoj (GBC) i Hrvatske stručne udruge za sunčevu energiju (HSUSE). Na taj način omogućili smo neposrednu povezanost i suradnju studentskih i poslovnih organizacija.

Udruga je uspješno odradila nekolicinu projekata u kojima su najuspješniji SUPEUS Case Study, BUS 2012 te izdavanje stručnog časopisa SUMA.



SUPEUSOV MAGAZIN ili skraćeno SUMA, jest magazin o obnovljivim izvorima energije, energetskoj efikasnosti i održivoj gradnji, a svečano je promoviran 8. ožujka 2013. godine na Fakultetu elektrotehnike i računarstva. Časopis objedinjuje sve aktivnosti i događanja te je jedan od najvećih projekata Udruge. Prvi broj časopisa posvećen je Hrvoju Turibaku, prvom i počasnom predsjedniku Udruge od kojeg je sama ideja i potekla. Tiskan je u nakladi od 1500 primjerak i izlazit će jednom godišnje. Namijenjen je studentima, tvrtkama, organizacijama i profesorima koji su zainteresirani ili rade na području energetske učinkovitosti i obnovljivih izvora energije. Ovim projektom, na jednom je mjestu pružen pregled svih projekata Udruge, aktualnih događanja, projekata i planova na području energetske učinkovitosti i održivog razvoja, ali i otvorena mogućnost studentima da objavljuju svoje radove, članke i ideje neovisno o članstvu u Udruzi. Časopis je rezultat isključivo studentskog rada.
Budućnost ugodnog stanovanja, ili skraćeno BUS, bio je drugi i dosad najveći projekt Udruge. To je besplatni seminar namijenjen studentima koji pokriva područja energetske učinkovitosti, obnovljivih izvora energije i održive gradnje. Ideja za organizacijom ovakvog projekta potekla je nakon prisustvovanja članove Udruge brojnim konferencijama i skupovima za stručno usavršavanje. Ideja je bila vrlo jednostavna: organizirati seminar za studente na kojem će predavati profesori, renomirani stručnjaci i predstavnici tvrtki, te prezentirati najvažnije i najaktualnije teme iz svijeta energetske učinkovitosti, obnovljivih izvora energije i održivosti.
Prvi seminar Budućnost ugodnog stanovanja održan je krajem 3. mjeseca 2012. godine i bio je prvenstveno namijenjen studentima arhitektonske, građevinske, elektrotehničke i strojarske struke. Međutim, sudionika je bilo i s drugih fakulteta, kao što su EFZG, RGN, PMF, FKIT... Ukupno trinaest predavanja bilo je podijeljeno u tri bloka predavanja s dvije pauze. Pri blok više se doticao građevinske i arhitektonske struke, drugi strojarske i treći elektrotehničke struke. Svako predavanje bilo je koncipirano tako da ga razumiju studenti koji ne studiraju dotično područje, ali da opet studentima koji su bolje upoznati sa sadržajem predavanja ne bude dosadno. Cilj je naravno bio okupiti što više studenata s različitih fakulteta, zainteresirati ih za različita područja i omogućiti im da nauče nešto novo.

Glavni cilj projekta bio je povezati studente različitih fakulteta kroz temu energetske učinkovitosti. S obzirom na broj prijavljenih studenata (326) može se reći da je glavni cilj ostvaren. Što se tiče sadržaja samog seminara rezultati anonimne ankete provedene među sudionicima pokazali su da postoji želja i potpora za daljnjim organiziranjem ovakvih događaja. Vrijednost cijelog projekta prepoznale su i tvrtke, njih 20, koje su omogućile organizaciju cijelog projekta, kao i tri medijska partnera koji su popratili projekt.

Ovogodišnji BUS imat će jedinstvenu temu, a to je Grad. Seminar će se održati 4. 5. 2013. godine na AGG-u u Zagrebu u Velikoj predavaonici (81), Kačićeva 26, 10000 Zagreb. Cijeli seminar organiziran je kroz 4 bloka. U prvom bloku i uvodnom dijelu nastojat će se prezentirati vizije i koncepti za razvoj suvremenog grada te važnost uključivanja javnosti u razvojne projekte. Kroz različita predavanja prezentirat će se i što sve obuhvaća stanovanje u jednom gradu. U drugom bloku prezentirat će se rješenja za konkretne probleme koji se javljaju u gradu. Predavanja će se dotaknuti otpada, proizvodnje i distribucije energije, promet, priprema i obrada voda, energetske obnove grada itd.

President's 2014 Budget Proposes Critical Investments in Clean Energy

 

President Barack Obama on April 10 requested a $28.4 billion Fiscal Year 2014 budget for the Energy Department, including $2.78 billion for the Energy Department's Office of Energy Efficiency and Renewable Energy (EERE). The request is part of the Administration-wide effort to strengthen the U.S. economy with energy that is cleaner, cheaper, and creates sustainable jobs.
As Assistant Energy Secretary Dr. David Danielson explained in an April 10 presentation, the $2.78 billion EERE portion of the request includes $615 million in funding for research and development into sources of renewable electricity generation such as wind, solar, water power, and geothermal energy. The proposed budget also includes $949 million for energy savings programs including the Federal Energy Management Program, Weatherization & Intergovernmental, building technologies, and advanced manufacturing. And the proposed FY 2014 budget includes a $957 million request for sustainable transportation, including research and development of vehicles, bioenergy, and fuel cell technologies. This segment includes $575 million for cutting-edge vehicle technologies research and $282 million in research into next-generation advanced biofuels. See the presentation on the EERE proposed FY 2014 budget PDF.
Overall, the budget request for the Energy Department invests in innovative research to lead in research, development, deployment, and production of clean energy technologies. It also creates a new Race to the Top for Energy Efficiency and Grid Modernization, and helps consumers and businesses save money and improve their energy efficiency through the President’s Better Buildings Initiative.
Other highlights in the FY 2014 budget include $80 million for advanced technologies and tools that improve clean energy integration into the grid; $147 million in research and development of smart grid investments, cybersecurity for energy control systems, and National Electricity Delivery within the Office of Electricity Delivery and Energy Reliability; and $2 billion for an Energy Security Trust to help transition U.S. cars and trucks off of oil. See the Energy Department press release and the White House blog.
 

First U.S. Grid-Connected Enhanced Geothermal System Deployed

 

The Energy Department on April 12 recognized the nation’s first commercial enhanced geothermal system (EGS) project to supply electricity to the grid. Based in Churchill County, Nevada, Ormat Technologies’ Desert Peak 2 EGS project has increased power output of its nearby operating geothermal field by nearly 38 %, generating an additional 1.7 megawatts of power. EGS technologies utilize directional drilling and pressurized water to enhance flow paths in the subsurface rock and create new reservoirs, capturing energy from resources that were once considered uneconomical or unrecoverable.
Leveraging a $5.4 million Energy Department investment—matched by $2.6 million in private sector funding—the Ormat Desert Peak project is extending the life of previously unproductive geothermal wells. Since the project’s start in 2008, the Energy Department has worked with Ormat, GeothermEx, the U.S. Geological Survey, and Lawrence Berkeley and Sandia National Laboratories to develop cost-effective and innovative production technologies that utilize protective environmental best practices and monitoring. The U.S. Geological Survey estimates that EGS in the United States has the potential to enable development of 100 to 500 gigawatts of geothermal resource capacity.

The U.S. Department of Energy (DOE) and its National Renewable Energy Laboratory (NREL) on April 11 announced the teams selected for the inaugural DOE Collegiate Wind Competition, which will take place in spring 2014. The Collegiate Wind Competition is a forum for undergraduate college students of multiple disciplines to investigate innovative wind energy concepts; gain experience designing, building, and testing a wind turbine to perform according to a customized business plan derived from market data; and increase their knowledge of wind industry barriers.
The 10 student teams selected through a competitive process are Boise State University, California Maritime Academy, the Colorado School of Mines, James Madison University in Virginia, Kansas State University, Northern Arizona University, Pennsylvania State University, the University of Alaska—Fairbanks, the University of Kansas, and the University of Massachusetts—Lowell.
The theme of the inaugural competition is to design and construct a lightweight, transportable wind turbine that can be used to power small electronic devices. A principal contest involves testing each team's prototype wind turbine in a wind tunnel under specific conditions. Each team's business plan and turbine will also be evaluated against other pre-weighted criteria. The third event of the competition will be a team-to-team debate relating to current wind market drivers and issues. The turbine from the college or university with the best overall score will be placed on temporary display at the DOE headquarters building in Washington, D.C. See the NREL press release.
 

USDA Announces $6 Million for Rural Smart Grid

 

The U.S. Department of Agriculture (USDA) on April 10 announced funding for projects to improve electric service in rural areas across 13 states, including more than $6 million in smart grid funding, which increases access to information to better manage electricity use. Overall, $280 million will be available through loans for rural electric infrastructure in Alabama, Colorado, Florida, Georgia, Iowa, Kansas, Kentucky, Minnesota, North Carolina, North Dakota, South Carolina, South Dakota, and Texas.
For example, the Georgia Transmission Corporation, which serves customers in Alabama and Florida in addition to Georgia, will receive a USDA loan that includes more than $3 million for smart grid projects. The Heartland Rural Electric Cooperative in Kansas will receive a USDA loan that includes more than $192,000 for smart grid projects. Smart grid technologies involve adding communication capabilities and control systems to the electrical grid that are intended to improve home energy management for the homeowner, provide greater demand control for the utility, and create a more reliable power grid overall. Smart grid technologies are also expected to better accommodate the use of renewable energy, all forms of on-site power production, and electric vehicles. See the USDA press release.
And on March 29, USDA announced that it is seeking applications to provide assistance to agricultural producers and rural small businesses for energy efficiency and renewable energy projects. Funding is available from USDA's Rural Energy for America Program. See the USDA press release.

EKO ZADAR DVA d.o.o.

 
 
U organizaciji Hrvatskog Centra Obnovljivih Izvora Energije (HCOIE) nastavljeno je predstavljanje hrvatskih visokotehnoloških tvrtki i poduzetnika na europskim i svjetskim portalima kojima je zajednički predznak energetika, obnovljivi izvori energije i očuvanje okoliša.
 „Želim naglasiti da će hrvatske tvrtke i poduzetnici ovdje biti promovirane ne samo da bi prodavali svoje proizvode nego i da bi svoje znanje razvoja informacijskih i energetskih tehnologija podijelile s sličnim svjetskim tvrtkama, poduzetnicima iz razvijenih nacija kojima se Republika Hrvatska prilagođava i politički i gospodarski. Nadam se da će naše prezentacije hrvatskih tvrtki i poduzetnika dovesti do suradnje između država, kompanija i poduzetnika do razine koja nije samo prijateljstvo nego i partnerstvo", istaknuo je Željko Serdar , predsjednik Hrvatskog Centra Obnovljivih Izvora Energije.
 
EKO ZADAR DVA d.o.o.
 
Tvrtka EKO ZADAR DVA d.o.o. na čelu s mr.sc. Vladimirom Matjačićem, dipl.oec. u prvoj je  fazi izgradnje vjetroelektrane radnog naziva ZD4.
 
 

Uz cestu Benkovac-Karin Donji, na sjeverno-istočnoj strani u kršu Bukovice, u tijeku je prva faza izgradnje vjetroelektrane radnog naziva ZD4 u vlasništvu privatne tvrtke Eko Zadar Dva d.o.o. Benkovac.
Za mjesec-dva započet će s komercijalnim radom prve četiri vjetroturbine snage 9,2 megawatta (MW), a na jesen i još šest vjetroturbina snage 18 MW.
Divovska konstrukcija
- Ulaganje je 360 milijuna kuna, za prvu fazu 120, a za drugu 240 milijuna kuna. Od toga su 30 posto vlastita sredstva, a 70 posto krediti Hrvatske banke za obnovu i razvitak (HBOR) te Zagrebačke banke (ZABA), kazao je Vladimir Matjačić, direktor Eko Zadar Dva d.o.o., predsjednik Nadzornog odbora i suvlasnik Heplasta iz Preloga u Međimurju, tvrtke koja proizvodi polietilenske i polipropilenske cijevi.
Ukupna snaga tih vjetroelektrana iznosi 27,2 MW, a proizvodnja će biti oko 90 milijuna kilovatsati (kWh) ili 25 tisuća MW godišnje, što je dovoljno za opskrbu preko 20 tisuća domaćinstava "zelenom energijom". Vjetroelektrane će u usporedbi s proizvodnjom električne energije pomoću kamenog ugljena i plina smanjiti emisiju štetnih tvari u atmosferu za oko 60.000 tona CO2 godišnje.

Divovska konstrukcija vjetroturbine je teška preko 130 tona. Rotor ima masu 62 tone, a gondola oko 80 tona. Promjer rotora agregata iznosi 108 metara, a na visinu od 90 metara podiže ga 500-tonska dizalica Zagrebtransa.
Koncesija 20 godina
- Investitori su domaći dok je stupove i vjetroagregate isporučio te ih montira Siemens Hrvatska. Od ukupne investicije od 360.000 milijuna kuna u Hrvatskoj ostaje preko 50 posto, prvenstveno u kupnji potrebitog materijala, gradnje komunalne infrastrukture te troškove izvođača radova i ishođenja potrebne dokumentacije.

Prihod od prve četiri vjetroturbine je oko 2,5 milijuna eura godišnje. Kada se cjelokupnoj investiciji dodaju troškovi rada, održavanja, administracije, osiguranja te ostali čimbenici potrebni za rad vjetroelektrane, realan povrat uloženog novca je oko 10 godina.
Iskorištavanje energije vjetra najbrže je rastući segment proizvodnje energije iz obnovljivih izvora.
- Koncesija je 20 godina dok će shodno ugovoru proizvedenu električnu energiju po definiranoj cijeni Hrvatski operator tržišta energije (HROTE) otkupljivati 12 godina. Preostale godine su po sadašnjim propisima tržišna utakmica.
Osim 400 MW trenutno na listi, Hrvatska u sljedećih sedam godina treba izgraditi dodatnih 800 MW vjetroelektrana. Riječ je o dijelu obveze da Hrvatska do 2020. godine 20 posto svoje električne energije proizvede iz obnovljivih izvora.

Energy Department Announces Apps for Vehicles Challenge Winners

 

The Energy Department announced the winners of the Apps for Vehicles Challenge on April 1. The competition asked app developers and entrepreneurs to demonstrate how the open data available on most vehicles can be used to improve vehicle safety, fuel efficiency, and comfort. The Department awarded the Judges' Prize to New York City-based Dash, which developed an app that turns any vehicle into a "smart car," providing real diagnostics and alerts to enable drivers to maximize engine performance, minimize carbon emissions, and save money. The Popular Choice prize went to MyCarma, headquartered in Troy, Michigan, which developed an app that offers a personalized fuel economy estimate based on a driver's unique driving patterns instead of a standard test cycle. Green Button Gamer, based in Boston, Massachusetts, won the Safety Innovation award, and Fuel Economy Coach, based in Augusta, Georgia, received the Fuel Efficiency Innovation award.
The Apps for Vehicles Challenge is focused on spurring innovative projects or services to reduce fuel costs and increase safety for consumers by utilizing vehicle-generated information, including data on engine speed, brake position, headlights, and distance traveled. Entries were judged based on their creativity, innovation, use of open vehicle data, consumer accessibility, and potential to help consumers improve fuel efficiency. The Energy Department announced the competition in October 2012, and from nearly 40 entries that were submitted for the first phase of the competition, seven were selected as finalists to advance to the second stage. See the Energy Department's Progress Alert and visit the Apps for Vehicles Challenge website to download the winning apps.
 

Energy Department Renews Funding for Bioenergy Research Centers

 

The Energy Department announced on April 4 that it would fund its three Bioenergy Research Centers for an additional five-year period, subject to continued congressional appropriations. The three centers were established by the Department's Office of Science in 2007 as an innovative program to accelerate fundamental research breakthroughs toward the development of advanced next-generation biofuels. The centers include the BioEnergy Research Center, led by the Department's Oak Ridge National Laboratory; the Great Lakes Bioenergy Research Center, led by the University of Wisconsin-Madison in partnership with Michigan State University; and the Joint BioEnergy Institute, led by the Department's Lawrence Berkeley National Laboratory. Each center is designed to be a large, integrated, multidisciplinary research effort, funded at the rate of $25 million per year, and they have consistently received high marks from outside reviewers for both their scientific productivity and the effective management and integration of their research efforts.
In their first five years of operation, the Bioenergy Research Centers have produced more than 1,100 peer-reviewed publications and more than 400 inventions, as recorded in invention disclosures or patent applications. Among the breakthroughs are new approaches for engineering non-food crops for biofuel production; reengineering of microbes to produce advanced biofuels such as "green" gasoline, diesel, and jet fuel precursors from biomass; and the development of methods to grow non-food biofuel crops on marginal lands so as not to compete with food production. In the next five years, emphasis will be on bringing new methods and discoveries to maturity, developing new lines of research, and accelerating the transformation of scientific breakthroughs into new technologies that can transition to the marketplace. See the Energy Department press release, and for more information on the centers, visit the Genomic Science Program website.
 

New Database Shows Benefits of Energy Efficiency Programs

 

The Energy Department on April 5 recognized a new publicly available database that offers federal, state, and local decision-makers information documenting the results of energy-efficiency programs in the Northeast and Mid-Atlantic regions. The Regional Energy Efficiency Database (REED), a project of Northeast Energy Efficiency Partnerships, provides a one-stop resource to readily access energy efficiency program data, including energy and peak-demand savings, costs, avoided emissions, and job impacts. This is part of the Energy Department's broader effort to improve public access to energy information, empowering consumers, industry, and government agencies to make informed decisions that save money by saving energy.
The REED database allows users to generate reports and download underlying data showing the impacts of ratepayer-funded energy efficiency programs in Connecticut, Maine, Maryland, Massachusetts, New Hampshire, New York, Rhode Island, and Vermont. REED will help inform a broad range of policy issues, including energy, economic, and air quality planning, and help demonstrate the long-term, money-saving benefits of energy efficiency investments. Specifically, policymakers, program administrators and other industry stakeholders can use the REED data for a variety of purposes, including comparing efficiency program impacts across states to help identify best practices in efficiency policy and program design, as well as informing progress toward clean air and climate change goals. The database currently includes 2011 electric and gas energy efficiency program data and will expand this fall to include 2012 data from Delaware and the District of Columbia, as well as the states currently in the database. See the Energy Department Progress Alert.
 

Manufacturing Energy Use Down Since 2002: EIA

 

Total energy consumption in the U.S. manufacturing sector decreased by 17% from 2002 to 2010, according to data released on March 19 by the U.S. Energy Information Administration (EIA). Manufacturing gross output decreased by only 3% over the same period. Taken together, these data indicate a significant decline in the amount of energy used per unit of gross manufacturing output. The significant decline in energy intensity reflects both improvements in energy efficiency and changes in the manufacturing output mix. Consumption of every fuel used for manufacturing declined over this period.
The manufacturing sector comprised more than 11% of U.S. gross domestic product (GDP) in 2010. The manufacturing base in the United States is broad, and includes energy-intensive industries such as petroleum refining, chemicals, aluminum, iron and steel, paper, wood products, and food, as well as less energy-intensive industries such as textiles, leather, apparel, furniture, machinery, and electrical equipment. Energy for manufacturing can be consumed in two ways: as a fuel or as a feedstock (material input to a final product). Energy consumed as a fuel includes all energy used for heat and power. Energy used as feedstock is the use of energy sources for raw material input or for any purpose other than the production of heat or power. See the EIA press release.

5 Super-Sized Solar Projects Transforming the Clean Energy Landscape

 

2012 marked a record year for America’s solar industry. Installations surged by 76% compared to 2011—representing an estimated market value of $11.5 billion. From commercial to residential, every sector experienced significant growth, but the clear standout of 2012 was utility-scale solar.
Utility-scale solar projects are designed to generate massive amounts of electricity. Unlike other sectors, the electricity generated by utility-scale projects is sold directly to wholesale utility buyers. In the recently released U.S. Solar Market Insight report, GreenTech Media and SEIA found that the utility-scale sector grew by an unprecedented 134% last year—with eight of the largest solar projects in America starting operation.
Many of these projects were supported by investments from the Energy Department’s Loan Guarantee Program. These investments—in several of the world’s largest solar generation facilities—help to lower the cost of financing and accelerate the completion of transformative clean energy projects. For the utility-scale projects that came online last year as part of the loan program portfolio, see the complete story, see the Energy Blog.
