L.A. Launches World’s Largest Green Hydrogen Power Plant, Ditches Coal
Los Angeles has officially transitioned away from coal-powered electricity, marking a significant step in its journey to achieve carbon-free energy by 2035. This announcement was made by Mayor Karen Bass, who revealed that the city has concluded its use of coal-fueled energy, as the final delivery from the Intermountain Power Project in Utah took place last week.
L.A.’s Green Hydrogen Initiative
The city is now focusing on launching the largest green hydrogen power plant in the world. Starting in the second quarter of 2026, the Intermountain Power Project will substitute coal with a blend of 70% natural gas and 30% green hydrogen. Eventually, the aim is to operate entirely on 100% hydrogen.
Details of the Power Plant
- Location: Delta, Utah
- Size of Hydrogen Storage: Comparable to the Empire State Building
- Initial Hydrogen Production Capacity: 21 million kilograms annually
- Electrolyzers Capacity: 220 megawatts
David Hanson, who manages power projects for the Los Angeles Department of Water and Power (LADWP), highlighted that the current hydrogen production process includes splitting water, which only releases oxygen. The hydrogen produced will be stored in a vast underground salt cavern adjacent to the plant, ensuring secure and leak-proof storage.
Advancements Amid Challenges
Despite facing challenges, including high production costs compared to traditional methods, L.A.’s green hydrogen project has gained momentum. The Biden administration supported this initiative with a $504 million loan guarantee aimed at enhancing the facility in Utah. The project is also supported by technological contributions from Mitsubishi Power.
Moreover, LADWP plans to modify its Scattergood Generating Station in West Los Angeles to accommodate hydrogen fuel in 2024. This shift aligns with the city’s longstanding effort to reduce carbon emissions.
Historical Context
Mayor Bass emphasized the progress L.A. has made over the past two decades. In 2003, only 3% of the city’s energy supply came from renewable sources, with over 50% reliant on coal. Now, Los Angeles proudly boasts that more than 60% of its energy is carbon-free, with coal usage reduced to zero.
As L.A. embarks on this new chapter in sustainable energy, officials remain optimistic about overcoming the challenges associated with green hydrogen technology. The ultimate objective is to provide a cleaner energy future for all residents.
