In another indication of growing U.S. utility interest in energy from hydrogen and in large-scale battery storage, Entergy Corp. and Mitsubishi Power Americas Inc., an affiliate of Japan’s Mitsubishi Heavy Industries Ltd., said that they will jointly develop “decarbonization projects” for Entergy’s utility operations in Arkansas, Louisiana, Mississippi and Texas.
The partnership will focus on tooling combined-cycle power plants to run on a mix of hydrogen and natural gas, creating hydrogen from renewable energy and nuclear power, transporting and storing hydrogen, and developing large-scale battery stations.
“New technologies and innovative solutions to the challenges posed by climate change present opportunities for us to significantly decrease carbon emissions from our generation portfolio while maintaining low rates,” Paul Hinnenkamp, Entergy’s chief operating officer, said in a statement.
Natural gas-fired generation accounts for roughly two-thirds of Entergy’s power portfolio, which includes more than 30,000 MW of capacity, according to S&P Global Market Intelligence data. The company also owns over 7,000 MW of nuclear generating capacity and more than 2,600 MW of coal-fired power plants, compared with less than 100 MW of renewables.
The collaboration builds on gathering momentum for hydrogen and battery storage to play central roles in what Paul Browning, president and CEO of Mitsubishi Power Americas, called “the next phase of decarbonization.” The companies did not immediately respond to a request for details on the volume, location and timing of the projects.
For Mitsubishi, the partnership with Entergy marks its latest hydrogen and battery storage deal with U.S. utilities and power plant developers. In early September, the developers of more than $3 billion in planned natural gas-fired generation projects in New York, Ohio and Virginia selected the company to supply hydrogen-compatible gas turbines as part of a package that includes creation of hydrogen using renewable energy, through the process of electrolysis, and hydrogen storage. That came after Mitsubishi in August announced a contract to build a 200-MW battery storage project in Texas and joined more than a dozen U.S. electric and gas utilities to launch a $100 million five-year research project to explore greater use of hydrogen and other low-carbon fuels.
