A project that stores coal-born carbon emissions underground, the proposed facilities will be retro-fitted on to a western Illinois-based coal-fired power plant.
Ken Humphreys, CEO of the coal company consortium FutureGen Alliance, told Associated Press that he expected construction to start this year.
However, he reportedly said the project still needed a permit to store the gas, a condition needed to secure the $1 billion of promised federal funding.
The project was first championed by the Bush administration in 2003, when it was associated with an eastern Illinois-based power plant.
