The US Department of Energy (DOE) will fund research organisation GTI and its partners for the next phase of a project exploring how stored hydrogen can be used for load following with a CCGT.
The project is to demonstrate storage of more than 54 MWh of energy in the form of hydrogen produced from natural gas with carbon capture and storage. The hydrogen would be used for load following at Southern Co . Services’ 122 MW Washington County Cogeneration Facility in McIntosh, Alabama. GTI said: “Hydrogen storage and discharge rates will be linked to follow daily power demand fluctuations from variable renewable energy to increase the plant’s efficiency while reducing emissions.”
The DOE awarded GTI $800 000, allowing it to proceed to Phase 2 of the project. This involves a Preliminary Front End Engineering Design study of the system, Project partners include: Southern Co., Pacific Gas & Electric , and the Electric Power Research Institute (EPRI). The total project cost is estimated at $1.1 million.
