Tag: carbon dioxideStartup Porifera is developing membranes to separate greenhouse gases from smokestacks. Sandia scientists successfully test a machine that creates fuel from carbon dioxide. Using CO2 to Extract Geothermal Energy Carbon dioxide captured from power plants could make geothermal energy more practical. Smaller and more practical electron-beam emitters could save millions of tons of C02 emissions. Mixing Solar with Coal to Cut Costs A new strategy could reduce coal plant emissions and cut the cost of solar power. Forget Curbing Suburban Sprawl Building denser cities would do little to reduce CO2 emissions, a new NAS report concludes. Combining synthetic biology and solar technology could provide a way to trap carbon dioxide and produce fuel. The DOE's backing revives a pioneering clean-coal project. A Preassembled Nuclear Reactor A new modular design could make building nuclear reactors faster and cheaper. An Ocean Trap for Carbon Dioxide A New Jersey plant is planning to put ocean-floor carbon sequestration to the test. Biofuels vs. Biomass Electricity Findings show that turning biomass into electricity is more beneficial than turning it into transportation fuels. Does Anyone Understand Geo-Engineering? Research may be needed to evaluate alternatives to reducing greenhouse-gas emissions. Energy and Climate Bill Advances Fear of EPA regulation could help it pass, says Congressman Markey. The Real Price of Obama's Cap-and-Trade Plan A carbon-emissions limit will raise energy prices unevenly. Ralph J. Cicerone, president of the National Academy of Sciences, discusses the challenges of climate-change research. |
