In today's search for renewable energy sources, researchers are turning to the hi-tech, from solar and hydrogen fuel cells, and the very low-tech. The latest example of a low-tech alternative comes from an age-old industry: paper. A new study reveals a sustainable way to turn the huge amounts of waste from paper production into solid fuel with the added bonus of diverting the sludge from overflowing landfills.
To prevent e-vehicles from overloading power grids while charging, seamless connectivity is required. To help address this issue, Fraunhofer ESK is developing underlying communication methods for a uniform energy management system.
Parabolic troughs and dry-cooled towers deliver similar value for concentrating solar power plants, despite different solar profiles, a new report by the Energy Department's National Renewable Energy Laboratory has found.
The Fraunhofer Institute of Optronics, System Technologies and Image Exploitation IOSB uses modern information technology to remotely measure the oscillatory pattern over the entire structure of the facility from several hundred meters away.
Satellite observations of global sea-surface temperature show that a 30-year upward trend has slowed down within the last 15 years. Climate scientists say this is not the end of global warming, but the result of a rearrangement in the energy flow of the climate system and, in particular, how the ocean stores heat.
The 2014 installment of the Sustainable Energy in America Factbook - produced for The Business Council for Sustainable Energy by Bloomberg New Energy Finance - has found that renewable energy, natural gas and energy efficiency advancements are leading a transformation of America's energy.
Extreme weather events like super-typhoon Haiyan and hurricane Sandy can have major negative impacts on the world economy. So far, however, the effects on global production and consumption webs are missing from most assessments.
While the debate over using crops for fuel continues, scientists are now reporting a new, fast approach to develop biofuel in a way that doesn't require removing valuable farmland from the food production chain. Their work examining the fuel-producing potential of Streptomyces, a soil bacterium known for making antibiotic.
Wastewater from pulp and paper mills contains large volumes of organic material that can be converted into biogas, according to findings by researchers from Water and Environmental Studies (WES) at Linköping University.
Gasoline-like fuels can be made from cellulosic materials such as farm and forestry waste using a new process invented by chemists at the University of California, Davis. The process could open up new markets for plant-based fuels, beyond existing diesel substitutes.
A breakthrough in the use of renewable raw materials in chemical production has been achieved by Karlsruhe Institute of Technology (KIT) and its industrial partner AVA Biochem. The partners developed an innovative hydrothermal method to obtain the organic compound from biomass. Being a platform chemical, 5-HMF can serve as a precursor for various materials.
