Researchers have found that the electrification of the white biotechnology is not merely a green dream, but an alternative to petrochemistry with realistic economical potential. Compared to classical sugar based bio-processes, bioelectrochemical processes promise improved yields, which could turn out to be a real game changer. The next generation of bio-production facilities may not only become more environmentally friendly, but also more economically competitive.
Lithium-ion batteries are common in consumer electronics. They are one of the most popular types of rechargeable batteries for portable electronics, with a high energy density, no memory effect and only a slow loss of charge when not in use. Now, researchers are exploring new energy storage technology that could give the battery an even longer life cycle.
Researchers investigated and compared volatile organic compounds (VOCs) emitted from 37 different products, such as air fresheners, cleaning products, laundry supplies, and personal care products, including those with certifications and claims of 'green' and 'organic'.
Whether it's swapping your car for an electric vehicle, or your natural gas furnace for geothermal heating, transitioning from fossil fuels to electric-powered technology is widely believed to be the best way to lower carbon emissions. But knowing where the electricity comes from to power those 'eco-alternatives' is critical. If that electricity comes from burning oil and coal, it might mean that green alternatives aren't that green after all.
Drivers have been slow to adopt electric vehicles due to 'range anxiety', the fear of becoming stranded with an empty battery. This phenomenon was recently addressed in a study that aims to explain range anxiety and determine whether hands-on experience can reduce drivers' stress.
The Energy Department's National Renewable Energy Laboratory (NREL) and the Electric Power Research Institute (EPRI) have launched the Clean Energy Incubator Network. The program, funded by the Energy Department, aims to improve the performance of clean energy business incubators, connect critical industry and energy sector partners, and advance clean energy technologies emerging from universities and federal laboratories.
The chemical signature of water vapor emitted by combustion sources such as vehicles and furnaces has been found in the smoggy winter inversions that often choke Salt Lake City. The discovery may give researchers a new tool to track down the sources of pollutants and climate-changing carbon dioxide gas.
Researchers have taken a step closer to producing solar fuel using artificial photosynthesis. In a new study, they have successfully tracked the electrons' rapid transit through a light-converting molecule.
To make ships more eco-efficient, engineers have been working with alternative fuels. A Norwegian engineer is currently pursuing a new approach: With Vindskip, he has designed a cargo ship that is powered by wind and gas.
Sewage sludge, green waste, production residue from the food industry, straw or animal excrement - with the biobattery's modular concept a much larger range of biomass can be utilized for energy recovery than previously. Researchers show that they can convert organic residues into electricity, heat, purified gas, engine oil and high quality biochar using this process.
Using models that blend global economics, geography, ecology and environmental sciences is essential to understanding how changes in trade and natural systems in one part of the world affect those in another, a review concludes.
