Los Angeles is being sold a story of green transformation. The centerpiece is the California Hydrogen Hub, branded as ARCHES, with more than a billion dollars in federal funding to launch hydrogen projects across the state. At the heart of that story sits the Scattergood Generating Station near Playa del Rey. Officials say it will pivot from fossil gas to hydrogen combustion, delivering clean energy for millions. In parallel, Southern California Gas Company (SoCalGas) is pushing its Angeles Link pipeline, marketed as the largest green hydrogen distribution system in the nation.
Taken together, these projects are pitched as progress. A closer look shows something else: an elaborate attempt to extend fossil infrastructure under a new label, with high costs for communities and uncertain climate benefits.
Scattergood has powered Los Angeles since the 1950s. The plan now is to retrofit two of its turbines to run first on a blend of natural gas and hydrogen, then on pure hydrogen by 2035. The price tag approaches $800 million. The project is flagged as a milestone in LADWP’s transition plan, but its design ensures the plant will keep burning fuels, releasing pollutants through smokestacks, for decades more.
The rhetoric of “modernization” hides the simple truth: Scattergood will not shut down. Instead, it will carry on as a combustion plant, only with hydrogen replacing methane.
To make this retrofit possible, Los Angeles needs a hydrogen supply chain. Enter Angeles Link, SoCalGas’s vision for a sprawling pipeline system delivering green hydrogen across Southern California. The pipeline, if built, could transport volumes equal to a quarter of today’s natural gas supply. The promise is that Scattergood and other aging gas plants could swap methane for hydrogen delivered by Angeles Link.
But the pipeline is still on the drawing board. The California Public Utilities Commission (CPUC) has only approved initial feasibility studies. Phase 1 examines routes, supply sources, and early stakeholder consultation. Later phases, still unfunded, would cost hundreds of millions and require full design, permitting, and regulatory review.
The plan claims Angeles Link will displace diesel, reduce natural gas use, and feed hydrogen into power plants, ports, and industrial facilities. In reality, its main function would be to guarantee a market for hydrogen combustion in L.A.’s old gas plants. Scattergood would likely become one of its first customers.
Marketing materials for both Scattergood and Angeles Link focus on eliminating carbon emissions. What they ignore is nitrogen oxides (NOₓ). When hydrogen burns in air, its flame burns hotter than methane, reacting with nitrogen to form NOₓ. These gases drive smog, respiratory illness, and heart disease. Research shows NOₓ from hydrogen combustion can equal or exceed levels from methane turbines.
For Los Angeles, where smog already violates federal standards and frontline communities live with asthma and lung disease, this is a disaster in the making. Hydrogen combustion does not solve the pollution problem; it changes its profile.
Producing hydrogen also demands resources. So-called “green hydrogen” requires splitting water through electrolysis, powered by renewable electricity. Each kilogram of hydrogen needs nine liters of purified water. Scaling this up to run Scattergood and other plants would consume over a billion gallons annually.
California is a drought-prone state. The idea of dedicating scarce water to fuel combustion turbines raises fundamental questions about priorities. Do we want to spend water on producing hydrogen for smokestacks, or use that same renewable power and water for direct electrification and resilient local supplies?
SoCalGas, the company behind the Angeles Link, is not an environmental nonprofit. It is the largest gas utility in the United States, with a direct interest in keeping pipeline infrastructure alive. Hydrogen provides the perfect vehicle. By framing hydrogen pipelines as climate solutions, SoCalGas can secure new subsidies, new ratepayer guarantees, and decades of relevance.
What is branded as clean innovation looks much more like corporate survival. A gas utility that should be planning a managed decline is instead writing itself a future under the hydrogen banner. Scattergood is simply the beachhead.
The benefits touted include construction jobs and economic activity. But construction jobs are temporary, and long-term employment at plants like Scattergood will remain small. The costs, meanwhile, are borne by ratepayers funding the retrofit, by taxpayers subsidizing hydrogen hubs, and by communities exposed to continued emissions.
Frontline neighborhoods—Inglewood, Lennox, Hawthorne—already live with disproportionate burdens of air pollution. Extending Scattergood’s life with hydrogen combustion entrenches this pattern of environmental injustice. Meanwhile, SoCalGas, LADWP, and private contractors secure billions in public funding.
LADWP’s own environmental analysis admitted that battery storage paired with renewables could serve the same role as Scattergood at lower cost and without smokestack emissions. Yet that alternative was pushed aside.
California already has some of the world’s largest grid-scale batteries online, proving reliability at scale. Solar-plus-storage, expanded transmission, energy efficiency, and demand response offer clean pathways without the risks of NOₓ or massive water use. Choosing hydrogen combustion instead is a political decision to preserve centralized fuel infrastructure, not a technical necessity.
The branding of Angeles Link and Scattergood relies on a convenient omission: not all hydrogen is created equal. Today, almost all hydrogen in the U.S. comes from methane reforming, producing large carbon emissions. Even “blue hydrogen” with partial carbon capture leaves a high footprint due to methane leaks. True green hydrogen requires massive amounts of renewable electricity and water, both scarce resources.
So when Scattergood is labeled a “green hydrogen-ready” plant, it hides the fact that the city has no guaranteed source of green hydrogen. Angeles Link may one day deliver it, but the project has no confirmed supply. Without that, the only practical option is fossil-derived hydrogen, which undercuts the entire climate argument.
By investing in hydrogen combustion infrastructure, Los Angeles risks locking itself into another generation of smokestack power. The logic is circular: build a hydrogen pipeline to justify retrofitting plants, retrofit plants to justify building a pipeline. Both create sunk costs that make shutting down combustion facilities politically and financially harder.
Instead of phasing out fossil gas plants, Los Angeles is engineering a pathway to keep them alive under a new name. This is not decarbonization; it is delay.
Hydrogen may play a role in decarbonization, but its role is narrow: steelmaking, shipping, long-haul aviation, or as a chemical feedstock. Burning hydrogen in urban power plants is unnecessary, wasteful, and harmful.
Los Angeles should reject the illusion of a hydrogen-powered Scattergood and the false promise of Angeles Link. The billions earmarked for retrofits and pipelines should be directed toward renewables, storage, and electrification. That path would not only cut carbon but also reduce smog, conserve water, and protect communities already bearing the costs of pollution.
Scattergood and Angeles Link together reveal the truth about California’s hydrogen hub. Behind the branding of clean innovation is a strategy to entrench fossil infrastructure with public money. Communities near Scattergood will still breathe polluted air. Water will be diverted to feed turbines. Utilities and pipeline companies will collect guaranteed profits.
The state calls this climate action. In reality, it is a dangerous detour. A real clean transition requires dismantling combustion infrastructure, not dressing it in green. Los Angeles must not fall for the mirage of hydrogen pipelines and hydrogen smokestacks. The choice is clear: invest in real solutions, or subsidize fossil survival with a new coat of paint.
