First nuclear hydrogen production at Nine Mile Point
Government-funded 1MW demonstration project starts up amid increasing interest in nuclear hydrogen
US energy company Constellation has started up its 1MW nuclear hydrogen demonstration project at Nine Mile Point in the state of New York. The project uses a proton-exchange-membrane electrolyser powered by nuclear energy to produce 560kg/d of hydrogen, meeting Nine Mile Point’s operational hydrogen use for cooling the plant. The US Department of Energy (DoE) awarded $5.8mn towards the $14.5mn total cost of the project. The DoE is also supporting three other nuclear hydrogen pilot projects. The Davis-Besse project in Ohio is expected to start hydrogen production this year, while the Prairie Island project in Minnesota and Palo Verde project in Arizona are likely to start up next year.
