Despite high expectations and extensive research and investment in the last decade, technological options are still in developing stages and key resources for algal growth are still too onerous for economically viable production of algal biofuels.
Researchers studied a range of measures for cutting food-related emissions. Besides reductions in beef and dairy consumption, they found that technology improvements will be crucial. Under favorable conditions, better technology could cut these emissions by as much as 50 percent.
A team of chemists and engineers have proven that concentrated light, heat and high pressures can drive the one-step conversion of carbon dioxide and water directly into useable liquid hydrocarbon fuels.
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.
