The plan is to steadily increase the hydrogen percentage to 100% by 2045, which will require upgrading or replacement of the turbines to be able to handle greater percentages of hydrogen. The project was granted a $ 504 million DOE loan in 2022.

Utility staff told the board it's critical to build an 840-megawatt gas-fired power plant to replace the coal-burning facility that DWP operates today. Without a traditional power plant, they said, the city might have trouble keeping the lights on when there's insufficient electricity being generated

Several additional U.S. natural gas-hydrogen hybrid power projects are underway, the largest of which is the
Intermountain Power Agency's planned conversion of an existing coal plant into an 840-MW combined-cycle gas facility by 2025 that would combust up to 30% hydrogen and gradually move to only

Construction on the plant began in
September 1981. Commercial operation of unit 1 started in June 1986, and unit 2 in May 1987. The project cost US$ 4.5 billion. The plant was originally designed for four units; however, only two units were built. In 2004, units 1 and 2 were uprated. These

Mitsubishi has natural gas units in operation using blends of up to 90% hydrogen, Mitsubishi
Marketing Vice President Todd Brezler told Utility Dive. The turbines it will bring to market "will be engineered to burn 30% hydrogen blends by 2025 and they will eventually be retrofitted to burn 100%

One expert noted in 2019 that using hydrogen to replace natural gas in power-plant turbines was theoretical and had never been done in practice, and a LADWP IPP official stated that the "economics remain to be seen" and "could be quite expensive."
