Study suggests that decarbonizing US transport sector by converting waste CO2 to fuels would require economical air-capture of CO2

Green Car Congress

Kreutz used two examples of CCTF systems in his analysis: biodiesel from microalgae and Sandia National Laboratory’s S2P process (an effort to utilize concentrated solar energy to convert waste CO 2 into synthetic fuels, earlier post ). Kreutz used what he called a bifurcated climate regime—i.e.,

Study finds that dry-feed gasification for coal-to-liquids is more efficient, lower-emitting and cheaper than slurry-feed; CCS cost-effective for reduction of CO2

Green Car Congress

Conventional CTL plant gasifies coal to produce a syngas which is then converted in a Fischer-Tropsch reactor to products. Even with CCS, the liquid product costs are comparable to recent crude oil prices. For a liquids-only configuration, CCS is a cheaper option when the CO 2 price exceeds $12/tonne.

Global CO2 emissions up 3% in 2011; per capita CO2 emissions in China reach EU levels

Green Car Congress

Global emissions of CO 2 increased by 3% last year, according to the annual report “Trends in global CO 2 emissions”, released by the EC Joint Research Centre (JRC) and the Netherlands Environmental Assessment Agency (PBL). At 3%, the 2011 increase in global CO 2 emissions is above the past decade’s average annual increase of 2.7%.
