Natures figured it out already, how to best break down food into fuel. Now scientists have caught up, showing that fungi found in the guts of goats, horses and sheep could help fill up your gas tank too.
A carbon-based active material produced from apple leftovers and a material of layered oxides might help reduce the costs of future energy storage systems. Both were found to have excellent electrochemical properties and stand for the environmentally compatible and sustainable use of resources.
Modern combustion engines become increasingly economical and clean. Engine developers, however, are now facing the technical conflict of whether fuel consumption or exhaust gas emission is to be further reduced. This Gordian knot might be cut by chemists' and engineers' further development of sophisticated fuels that help optimize combustion in the engine.
A project is testing whether high-tech objects that look a bit like artificial trees can generate renewable power when they are shaken by the wind - or by the sway of a tall building, traffic on a bridge or even seismic activity.
Lithium-air batteries hold the promise of storing electricity at up to five times the energy density of today's familiar lithium-ion batteries, but they have inherent shortcomings. Researchers have proved that a new prototype is powered by a surprising chemical reaction that may solve the new battery's biggest drawback.
Europe wants to reduce its needs for raw materials and raise the level of recycling of resources in the solar power industry. If this project is successful, greenhouse gas emissions from solar panel manufacture will fall by 25 to 30 per cent.
Governments should not be abandoning carbon capture and storage, argues a researcher, as it is the only realistic way of dramatically reducing carbon emissions. Instead, they should be investing in global approaches to learn what works - and what doesn't.
Second-generation biofuel crops like the perennial grasses Miscanthus and switchgrass can efficiently meet emission reduction goals without significantly displacing cropland used for food production, according to a new study.
