The inaugural 2016 Sustainable Transportation Summit will serve as a forum to share ideas and perspectives on opportunities to accelerate the commercialization and deployment of advanced transportation technologies and smart mobility systems over the next decade.
Next generation concentrating solar power (CSP) system designs use supercritical carbon dioxide (sCO2) turbine power cycles to more efficiently convert solar thermal energy to electricity and to reduce the cost of CSP technology. Because sCO2 power cycles work best at very high temperatures and under intense pressure, a CSP system needs receivers and heat exchangers that can withstand these conditions.
The Energy Department’s Clean Cities program has welcomed the Northern Florida Clean Fuels Coalition in Jacksonville into its network of nearly 100 coalitions across the country. As part of Clean Cities, this group will continue to minimize the use of petroleum in transportation throughout their area.
The utility sector is going through a rapid transformation as more renewables come online and more Americans choose to go solar. Adding large quantities of distributed energy onto the grid requires the workforce to acquire new knowledge and skills, which SunShot is enabling through its GEARED program.
The 2016 National Algal Biofuels Technology Review, which was just released today, captures the exciting achievements of the field of algal biofuels, as well as articulates new challenges, lessons learned, and critical next steps.
Nearly all Americans rely on heavy-duty, long-haul trucks that haul our goods and services, deliver our food, and help keep our economy humming along. Thanks to the Energy Department's widely successful SuperTruck Initiative, these vehicles are becoming more fuel-efficient, which saves money spent on gas and reduces harmful carbon emissions.
When President Obama and Indian Prime Minister Modi met earlier this month, they pledged to show global leadership in the fight against climate change and reaffirmed their commitment to collaboratively support India’s ambitious goal to deploy 175 gigawatts of renewable energy, including 100 gigawatts of solar, by 2022.
With the potential to reduce the weight of vehicle components by up to 60%, carbon fiber composites is one of the most promising lightweight materials available to improve vehicle efficiency. However, its current inputs and manufacturing processes are expensive, severely limiting its use in most high-volume vehicle models.
The Quadrennial Energy Review (QER) is an assessment of the changing energy landscape in the United States. Play your role in helping America meet its objectives of reliable, affordable, and clean energy by submitting your comments to the QER's latest installment by July 1.
The Cleantech University Prize Collegiate Competition has traveled coast-to-coast over the past four months to find America’s next clean energy entrepreneurs. Meet the teams that will compete for $100,000 in prizes at the National Competition this week in Denver.
Dormitory mini fridges, dishwashers in dining halls, and campus computer labs are just a few of the things that can create large utility bills for colleges and universities across the country. The SunShot Initiative is working to make it easier for college campuses to use solar energy to help ease the financial burden of around-the-clock operation.
The Geothermal Technologies Office (GTO)'s major long-term goal is to realize enhanced geothermal system (EGS) technologies’ vast potential through commercial, cost-competitive, EGS power production. In pursuit of this goal, GTO funds research and development (R&D) and field demonstrations to facilitate new, innovative technology deployment and validation to reduce costs and improve performance of these man-made geothermal reservoirs.
American manufacturing is primed for a comeback thanks in part to President Obama’s vision and a sweeping initiative led by the Energy Department - the Clean Energy Manufacturing Initiative - to spur new alliances, investments and innovation in clean energy technologies.
The U.S. Department of Energy's Office of Energy Efficiency and Renewable Energy's Wind and Water Power Technologies Office provides a simple step-by-step project on building a wind turbine in less than 20 minutes.
The SunShot Initiative’s new systems integration program manager, Dr. Guohui Yuan, maintains a steadfast commitment to add more solar energy onto the nation’s electrical grid while always striving to achieve the office’s broader goals. “Because of my physics background I always look at problems at the system level — not just the issue, but the big picture,” he says.
The Energy Department’s Cleantech University Prize recently wrapped up its regional collegiate competitions. The California Institute of Technology and the University of Central Florida (UCF) each hosted student-led startup teams as part of the entrepreneurial clean energy contest.
The Energy Department's Bioenergy Technologies Office (BETO) works to enable a sustainable bioenergy industry that protects natural resources and advances environmental, economic, and social benefits. BETO recently sponsored a five-day Bioenergy Study Tour of the southeastern United States to highlight innovations that are bringing the industry one step closer to these goals.
What’s the difference between a hydrogen refueling dispenser and a traditional gasoline dispenser that you see at your local gas station? Not that much, actually. A hydrogen refueling dispenser is used to power a fuel cell electric vehicle (FCEV). But instead of using a combustible gas-powered engine, a FCEV carries a fuel cell onboard that uses hydrogen to power an electric motor which makes the car run.
Thanks to a DOE Building Technologies Office funding award, QM Power is demonstrating its technology, called the Q-Sync fan motor, in supermarkets across the country, with DOE and utilities verifying the savings. Customers are now using these successful demonstrations to accept and commercialize the Q-Sync fan in their refrigeration units.
The Department of Energy and the University of North Dakota have been recognized by the Geothermal Energy Association for launching the first commercial project that produces geothermal power from an oil and gas well.
