Tests lead to doubling of fuel cell life 05/22/2013
Researchers working to improve durability in fuel cell powered buses have discovered links between electrode degradation processes and bus membrane durability. The team is quantifying the effects of electrode degradation stressors in the operating cycle of the bus on the membrane lifetime.
Top-class biofuel from the depths of the forest 05/22/2013
Tops and branches from tree-felling sites are reborn in the laboratory as compact pellets. However, the energy industry will not act until the price is right.
Engineers devise new way to produce clean hydrogen 05/21/2013
Engineers have developed a novel method for producing clean hydrogen, which could prove essential to weaning society off of fossil fuels and their environmental implications.
Bacteria use hydrogen, carbon dioxide to produce electricity 05/19/2013
Researchers have engineered a strain of electricity-producing bacteria that can grow using hydrogen gas as its sole electron donor and carbon dioxide as its sole source of carbon.
Artificial forest for solar water-splitting: First fully integrated artificial photosynthesis nanosystem 05/16/2013
Researchers have created the first fully integrated artificial photosynthesis nanosystem. While "artificial leaf" is the popular term for such a system, the key to this success was an "artificial forest."
New endurance record for small electric unmanned aerial vehicle 05/10/2013
Using liquid hydrogen fuel stored in a new NRL-developed cryogenic fuel storage tank, the flight shatters the previous 26-hour record set by the UAV in 2009.
Recipe for low-cost, biomass-derived catalyst for hydrogen production 04/24/2013
Researchers have described details of a low-cost, stable, effective catalyst that could replace costly platinum in the production of hydrogen. The catalyst, made from renewable soybeans and abundant molybdenum metal, produces hydrogen in an environmentally friendly, cost-effective manner, potentially increasing the use of this clean energy source.
Special E. coli bacteria produce diesel on demand 04/22/2013
It sounds like science fiction but scientists have developed a method to make bacteria produce diesel on demand. While the technology still faces many significant commercialization challenges, the diesel, produced by special strains of E. coli bacteria, is almost identical to conventional diesel fuel and so does not need to be blended with petroleum products as is often required by biodiesels derived from plant oils.
