  1. Giving FutureGen a Second Chance

    FutureGen -- the carbon-neutral coal power project initiated and then killed under the Bush Administration -- looks increasingly likely to be resuscitated under President Obama after proponents met with Energy Secretary Steven Chu this week. There is now good reason to take a fresh look at this proposed coal gasification power plant which integrates carbon capture and storage (CCS) from the ground up. Those words don't come easy for this longtime FutureGen critic. But the context has changed since FutureGen was conceived in 2003, …

  2. Stealth Coal: Like it or lump it

    Oil and gas major ConocoPhilips and coal giant Peabody Energy applied for a permit yesterday to build a plant in Muhlenberg County, Kentucky to turn coal into synthetic natural gas. What interests me are not so much the details of their project but the fact that it's just one more example of what a longtime source of mine, Gasification Technologies Council CEO Jim Childress, calls stealth coal. …

  3. Clean Coal's Mountainous Upstream Blindspot

    Gasification-based IGCC power plant technology offers a powerful means of cleaning up local air pollution from coal-fired power and, via carbon capture and storage, its carbon footprint. I have argued in past that it should be legally mandated for new power plants burning coal because (1) air pollution laws require use of the best emissions controls available, (2) carbon capture and storage will be economically viable under emerging carbon caps and taxes, and (3) adding new carbon emissions from coal is …

  4. 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; …
