To meet a goal set by the US Environmental Protection Agency's Renewable Fuels Standard to use 36 billion gallons of biofuels each year - mostly ethanol - the nation must expand its infrastructure for transporting and storing ethanol. Ethanol, however, is known for triggering stress corrosion cracking of steel. Researchers investigated the mechanism of how ethanol triggers stress corrosion cracking along with ways to circumvent this issue to prevent ethanol-related corrosion issues.
The National Renewable Energy Laboratory recently issued a new report, 'Non-Hardware ('Soft') Cost-Reduction Roadmap for Residential and Small Commercial Solar Photovoltaics, 2013'. The report builds off NREL's ongoing soft-cost benchmarking analysis and charts a path to achieve SunShot soft-cost targets of $0.65/W for residential systems and $0.44/W for commercial systems by 2020.
Solar modules are exposed to many environmental influences that cause material to fatigue over the years. Researchers have developed a procedure to calculate effects of these influences over the long term. This allows reliable lifespan predictions.
Global production of photovoltaic cells grew by 10% in 2012 in comparison to 2011 despite a 9% decline in solar energy investments according to the annual 'PV Status Report' released by the European Commission's Joint Research Centre.
The water budget of the troposphere, the bottom layer of the Earth's atmosphere, determines the weather and plays a central role in climate change. The isotope composition of water vapor, i.e. the ratio of light and heavy water molecules, provides insight into underlying mechanisms. Climate researchers gather the data required by in-situ measurements as well as by using remote sounding instruments, e.g. on board of satellites. In a recent campaign, they combined both methods and proved the precision of remote sounding measurements for the first time.
The synthesis stage of the bioliq pilot plant successfully started operation. Now, all stages of the bioliq process, i.e. flash pyrolysis, high-pressure entrained-flow gasification, and synthesis, have been realized. The project will now be completed by testing the entire process chain and optimizing it for the large industrial scale.
A major scientific breakthrough in the development of renewable energy sources and other important chemicals; The research team succeeded in producing 580 mg of gasoline per liter of cultured broth by converting in vivo generated fatty acids.
A new analysis of the last decade of investment in California's clean technology sector shows that although venture capitalists remain key players, different types of investors are becoming ever more important to the growth of the sector.
The University of California, Davis, has been selected in a national competition this week to lead a two-year, $11.2 million research consortium for the U.S. Department of Transportation, focused on addressing and preparing for climate change.
There is a current superstar species of blue-green algae that, through its powers of photosynthesis and carbon dioxide fixation, or uptake, can produce ethanol, hydrogen, butanol, isobutanol and potentially biodiesel. Now that's some five-tool player.
The DUT Racing team from TU Delft has broken the world record for acceleration from 0 to 100 km/h for electric cars. The previous record stood at 2.68 seconds, but as of today the record is now held by the TU Delft students with 2.15 seconds.
