Scientists at the Department of Energy's Oak Ridge National Laboratory have designed and tested an all-solid lithium-sulfur battery with approximately four times the energy density of conventional lithium-ion technologies that power today's electronics.
All chefs know that 'you have to break some eggs to make an omelet', and that includes engineers at Iowa State University who are using high-frequency sound waves to break down plant materials in order to cook up a better batch of biofuel.
That the United States and Europe have been following different energy policies over the past few decades won't come as a surprise. However, according to one researcher, their divergence - with the US leading 'the shale gas revolution' and Europe investing heavily in modern renewables - is a good thing for the development of both alternative-energy sources.
Researchers identified a number of hotspots both of global climate change impacts and the science that deals with them. New analyses presented at the Impacts World 2013 Conference this week in Potsdam, Germany, revealed that the Amazon region, east Africa and the Mediterranean will experience serious change if greenhouse-gas emissions continue unabated.
Neptune, a pioneering system that performs offshore wind measurements, has begun to operate today at the Petroleum Bridge in Badalona. It consists of an eOLOS buoy to measure velocity profiles and wind direction high above sea level, and NEPTool, a tool that predicts wind speed, sea currents and waves in the short and long term with high spatial and temporal resolution.
Directly removing CO2 from the air has the potential to alter the costs of climate change mitigation. It could allow prolonging greenhouse-gas emissions from sectors like transport that are difficult, thus expensive, to turn away from using fossil fuels. And it may help to constrain the financial burden on future generations.
Lawrence Livermore scientists have discovered and demonstrated a new technique to remove and store atmospheric carbon dioxide while generating carbon-negative hydrogen and producing alkalinity, which can be used to offset ocean acidification.
As part of the Open Government initiative launched by the Obama Administration, Sandia National Laboratories' Technical Reference on Hydrogen Compatibility of Materials has made its debut on the Energy Dataset of OpenEnergyInfo, or OpenEI.
