..., we can expect to completely replace gasoline and diesel
with cellulose-derived biofuels that are cheaper, better for the environment and much better for national security than petroleum-derived fuels," Dale said....
New biofuels process promises to meet all US transportation needs
...concept economically competitive with gasoline and diesel
fuel would require research in two areas: finding ways to produce cheap hydrogen from carbon-free sources and developing a new type of gasifier needed for the process. "Having said that, this is the first concept for creating a sustainable system ...
Biodiesel won't drive down global warming
...rapeseed was instead used to grow trees, petroleum diesel
would emit only a third of the CO2 equivalent emissions as biodiesel. Petroleum diesel
emits 85% of its greenhouse gases at the final stage, when burnt in the engine. By contrast, two-thi...
