FutureGen was a project to demonstrate capture and sequestration of waste carbon dioxide from a coal-fired electrical generating station. The project (renamed FutureGen 2.0) was retrofitting a shuttered coal-fired power plant in Meredosia, Illinois, with oxy-combustion generators.  The waste CO would be piped approximately  to be sequestered in underground saline formations. FutureGen was a partnership between the United States government and an alliance of primarily coal-related corporations. Costs were estimated at US$1.65 billion, with $1.0 billion provided by the Federal Government.
First announced by President George W. Bush in 2003, construction started in 2014 after restructuring, canceling, relocating, and restarting. Citing an inability to commit and spend the funds by deadlines in 2015, the Department of Energy withdrew funds and suspended FutureGen 2.0 in February, 2015. The government also cited the Alliance's inability to raise the requisite amount of private funding. The Meredosia power plant that had been planned for retrofit was demolished around 2021.
FutureGen 2.0 would have been the most comprehensive Department of Energy Carbon Capture and Storage demonstration project, involving all phases from combustion to sequestration. FutureGen's initial plan involved integrated gasification combined cycle technology to produce both electricity and hydrogen. Early in the project it was to be sited in Mattoon, IL.
