  1. 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; …

  3. 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 …
