  1. Europe Shortlists Capture Projects for Stimulus

    European leaders shortlisted a dozen proposals to demonstrate large-scale carbon capture and storage at coal-fired power plants last month as eligible to share â'¬900 million of the EU's â'¬5-billion stimulus funding package. The goal is to bring down the cost of carbon-neutral coal power -- which the European Commission expects to continue to exceed the cost of conventional coal power in 2020 -- and to gain more experience with underground storage of CO2. Seven propose to capture CO2 post-combustion from the exhaust of conventional coal-fired power plants, a relatively inefficient process that nonetheless …

  2. Underground Coal Combustion

    UPDATE BELOW An article in the Wall Street Journal reports on a technology it says is getting a lot of attention in China, which it--misleadingly, I believe--refers to as underground coal gasification. That makes it sound as if coal is gasified, as in IGCC, creating a syngas that's burned. But actually the technology seems to more closely resemble oxyfiring, a technology Vattenfall is just now demonstrating for the first time at larger-than-laboratory scale at a plant in East Germany. In the approach described in the Journal, coal is ignited underground and fed a piped-down stream of pure oxygen; …

  4. New York State Gets Behind Oxyfuel Carbon Capture

    In a somewhat startling development, New York's governor David Paterson announced on June 10 that the state will support construction of an experimental "oxyfired" electric generation plant, in which coal will be burned in an atmosphere of almost pure oxygen, so that nitrogen emissions are eliminated and carbon capture simplified. Sweden's Vattenfall and France's Alstom are completing a similar demonstration plant in eastern Germany, as described in the "winners & losers" January issue of Spectrum, and Babcock & Wilcox has had a serious oxyfuel R&D program in the United States. But oxyfuel has not been the mainstream approach …

  6. U.S. Government Terminates Its Major Clean Coal Project

    By far the most important project in the U.S. governmentâ''s carbon sequestration program came to a screeching end on 31 January with the announcement by the U.S. Secretary of Energy that the department was pulling the plug on FutureGen. The basic idea of FutureGen, which goes back more than a decade, was to develop an integrated carbon-free coal gasification technology, where the gas would drive electric power turbines, separated hydrogen might power fuel cells, and the captured carbon dioxide would be permanently disposed of in geologic repositories. With the demise of FutureGen, whether it turns out to be somewhat exaggerated …
