DOE to provide ~$1B in cost-shared funding to FutureGen; oxy-combustion of coal with carbon capture and storage
The US Department of Energy (DOE) has decided to provide approximately $1 billion (earlier post) of cost-shared funding to the FutureGen Industrial Alliance (the Alliance) for the FutureGen 2.0 Project. (Earlier post.) The FutureGen 2.0 Project is a public-private partnership formed for the purpose of developing the world’s first commercial-scale, coal-fueled oxy-combustion electric generation project integrated with carbon capture and geologic storage.
DOE’s decision is to implement the proposed action in the Final Environmental Impact Statement (EIS) for the FutureGen 2.0 Project (DOE/EIS-0460). The EIS evaluates the potential environmental impacts associated with construction and operation of the project.
For the FutureGen 2.0 Project, the Alliance, cooperating with Ameren Energy Resources (Ameren), will construct and operate a 168-megawatt electrical (MWe) gross output coal-fueled electric generation plant using advanced oxy-combustion technology. Oxy-combustion is the combustion of coal with a mixture of manufactured oxygen and recycled flue gas (instead of air), resulting in a gas by-product that is primarily CO2.

The plant will use existing infrastructure, including the existing steam turbine generator (Unit 4), at Ameren Energy Resources’ Meredosia Energy Center on the Illinois River just south of Meredosia, Illinois.
The proposed project will include facilities designed to capture at least 90% of the CO2 that would otherwise be emitted to the atmosphere during steady-state operation, equivalent to approximately 1.2 million tons (1.1 million metric tons) of CO2 captured per year.
The captured CO2 will be compressed and transported via a new underground pipeline, approximately 30 miles long and nominally 10 to 12 inches in diameter, to a geologic storage area in eastern Morgan County, where it would be injected and stored in the Mt. Simon Formation (a saline aquifer) approximately 4,000 feet below the ground surface.

The Alliance will upgrade one unit in a power plant currently owned by Ameren near Meredosia, Illinois. The repowered unit will include oxy-combustion and carbon capture technologies designed to capture at least 90% of its CO2 emissions during steady-state operation and reduce other emissions to near zero.
The captured CO2 will be transported through an approximately 30-mile pipeline to wells where it will be injected approximately 4,000 feet below ground into a geologic saline formation for permanent storage.
The Alliance will also construct and operate visitor, research, and training facilities related to carbon capture and storage in the vicinity of Jacksonville, Illinois.
The DOE-funded demonstration period will last for 56 months from the start of operations (approximately 2017) through 2022.
