A new power plant in Nakoso, Japan, might someday change everything for coal plants.Since the new power plant fired up in September, the designer, Mistubishi, is expecting to prove it's possible to burn coal without polluting.This technology is known as integrated gasification combined cycle (IGCC).Proving IGCC works should give Mitsubishi's US partner, NRG Energy, the jump other hurdles to building new clean plants.

The project promised to solve the problem of the ages for power plants: how to produce cheap, clean, reliable electricity.No existing technology can do all three perfectly.

The problem is IGCC isn't there yet.It costs about 20 percent more than traditional plants.And even though it's easier to collect the resulting carbon dioxide from an IGCC plant than a traditional plant, there's no proven way to get rid of the greenhouse gas.One plan is to drill a shaft(通道) to pump the carbon dioxide underground, into saltwater formations.But there's no guarantee it will remain underground forever.

NRG administrators think solving the IGCC riddles is worth the trouble because they expect the U.S.will soon limit the amount of carbon dioxide that power generators may give out .

"With the additional cost of IGCC, to just voluntarily build something that's 20 percent more expensive, that’s commercial suicide," NRG chief administrator, David Crane said.

NRG administrators expect the cost to decline after six or seven plants are built.But other industry experts think it will take about a dozen plants for the price to be competitive with traditional coal plants.

Takaya Watanabe, a vice general manager of Mitsubishi, admits that the cost challenges are difficult.“It’s good for a company to say we want to be green, but unless someone is willing to pay, it's a dream.It won't keep our family eating rice," he said.

    A.To make electricity without polluting the air.
