CenterPoint Energy’s green hydrogen project in Minneapolis is now operational. The project uses renewable electricity to split hydrogen from water, which is then blended in low concentration within its own distribution system.
CenterPoint Energy is one of the first natural gas utilities in the United States to produce and add green hydrogen to its distribution system. Because there are no carbon emissions from either its production or end-use, green hydrogen has the potential to be an important zero-carbon supplement to conventional natural gas.
The project’s one-megawatt electrolyzer is powered by renewable electricity and can produce up to 60 Dekatherms (432 kilograms) of hydrogen gas per day, using approximately two gallons of…
