NH 'clean coal' company Powerspan featured in article about the business of cleaning up China

Powerspan Corp., a Portsmouth-based firm that has developed what it says is a commercially feasible carbon-capture and cleanup system for coal-fired power plants, is featured in a Slate.com piece about America firms rushing into China to tackle that country's godawful pollution problems.

“We were not able to bring it to market in the U.S., because the market never materialized,” CEO Frank Alix is quoted as saying. The article notes that our flat market for electricity, plus ultra-cheap natural gas, means it's not worth the cost to retrofit existing coal plants. In smog-choked, electricity-starved China, the picture is different.
