Tag: emissionsFuel from Coal-Eating Microbes A process for converting coal into natural gas could help reduce emissions. Will putting a price on carbon increase the use of renewables? Jet fuel made from an inedible plant will power an aircraft. A Better Way to Capture Carbon New materials provide a potentially cheaper way to reduce carbon dioxide emissions from power plants. The DOE's decision to abandon FutureGen could accelerate clean-coal technology. Some still question the vehicle's chances of success, despite a boost from India. As the primaries near, the presidential candidates are calling for similar, ambitious growth in ethanol biofuel. Running Cars on Hydrogen Made from Starch A new way to make hydrogen from corn or potatoes could make fuel-cell vehicles more practical. Research shows that pyrolysis is the most climate-friendly way to consume biomass. Consumers may find that the virtues of biodegradable plastics are really a mixed bag. Propane chemically derived from corn could be used in heating and transportation. Picking a Winner in Clean-Coal Technology A new MIT study says that no single technology is the solution to economically cutting carbon-dioxide emissions from coal. A new MIT report says that much more effort is needed to develop and test technology that will make clean-coal power plants economical and practical. No matter how well they're engineered, hydrogen cars offer no real answer to the imminent threats posed by global warming. Tax Credits for Plug-In Hybrids? Washington's growing interest could help make plug-in hybrids more affordable. The payoff: 150 miles per gallon. |
