Tag: carbon dioxideUsing Rust to Capture CO2 from Coal Plants Process could capture carbon more cheaply. Startup 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. 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. |
