Converting Coal Power Plants to Nuclear Gains Steam

Cars That Think

On a planet aspiring to become carbon neutral, the once-stalwart coal power plant is an emerging anachronism. It is true that, in much of the developing world, coal-fired capacity continues to grow. But in every corner of the globe, political and financial pressures are mounting to bury coal in the past.

Mitsubishi Hitachi Power Systems introduces 63% efficient, 540MW JAC gas turbine; -70% CO2 compared to older coal-fired plants

Green Car Congress

Replacing older coal-fired power plants with the enhanced JAC can reduce CO 2 emissions nearly 70%. To convert the J-series from steam cooling to air cooling, modifications were made to the combustor and thermal barrier coatings were enhanced in the turbine section to allow for the higher firing temperature. reliability.

Modified SOFC anodes allow operation at lower temperatures with carbon-containing gases; potential for much more efficient and cleaner generation of electricity from coal

Green Car Congress

Using barium oxide nanoparticles, a team of researchers led by Georgia Tech has modified the surface of conventional anodes for solid oxide fuel cells (SOFCs) to enable operation at lower temperatures (750 °C) with carbon-containing gases—e.g., gasified coal—by eliminating the coking problem.

DOE Regional Partner Initiates Coal Seam CO2 Injection and Methane Recovery Study in Virginia

Green Car Congress

A US Department of Energy (DOE) team of regional partners has begun injecting carbon dioxide into coal seams in the Central Appalachian Basin to determine the feasibility of CO 2 storage in unmineable coal seams and the potential for enhanced coalbed methane recovery. feet in thickness. trillion cubic feet.

Alabama Project Testing Potential for Combining CO2 Storage with Enhanced Methane Recovery

Green Car Congress

Earlier, an existing coalbed methane well operated by El Paso Exploration & Production had been converted for CO 2 injection, and four wells drilled to monitor reservoir pressure, gas composition, water quality, and the CO 2 plume. Coal in the Black Warrior Basin has the potential to sequester 1.1 gigatons to 2.3
