Another big car company gives up on hydrogen

Stellantis, the automotive giant behind Chrysler, Citroen, Fiat, Jeep and Peugeot, is pulling out of hydrogen. The company said it’s killing its fuel cell development program in the face of “limited availability of hydrogen refueling infrastructure, high capital requirements and the need for stronger consumer purchasing incentives.” To put that another way, it’s realized hydrogen EVs are facing the same set of challenges it’s not been able to overcome in the last two or three decades. It’s a st

Stellantis abandons hydrogen fuel cell development

To paraphrase Mean Girls, "stop trying to make hydrogen happen." For some years now, detractors of battery electric vehicles have held up hydrogen as a clean fuel panacea. That sometimes refers to hydrogen combustion engines, but more often, it's hydrogen fuel cell electric vehicles, or FCEVs. Both promise motoring with only water emitted from the vehicles' exhausts. It's just that hydrogen actually kinda sucks as a fuel, and automaker Stellantis announced today that it is ending the developmen

Amogy raises $80M to power ships and data centers with ammonia

From tariffs to the recent reconciliation bill, climate tech startups have been grappling with a rapidly changing landscape. Brooklyn-based startup Amogy has managed to avoid turbulence induced by U.S. politics by keeping its sights on more promising foreign markets. Amogy’s ammonia-to-power tech and its focus on Asian markets, including Japan, South Korea, and Singapore, has helped it land a fresh $23 million in funding. The round, which brings its most recent fundraise to $80 million, increas

Tulum Energy rediscovered a forgotten hydrogen tech and used it to raise $27M

It was a mistake that was ahead of its time. Between 2002 and 2005, engineers with the Techint Group were trying to dial in a new electric arc furnace for a steelmaker when they noticed something odd. The carbon electrodes, rather than breaking down, were growing larger. The team had inadvertently created what’s known as a pyrolysis reaction, which is basically burning something in the absence of oxygen. In this case, the furnace was splitting methane into pure hydrogen and pure carbon. The te

The Download: Namibia’s hydrogen hopes, and fixing AI evaluation

Factories have used fossil fuels to process iron ore for three centuries, and the climate has paid a heavy price: According to the International Energy Agency, the steel industry today accounts for 8% of carbon dioxide emissions. But it turns out there is a less carbon-­intensive alternative: using hydrogen. Unlike coal or natural gas, which release carbon dioxide as a by-product, this process releases water. And if the hydrogen itself is “green,” the climate impact of the entire process will

Namibia wants to build the world’s first hydrogen economy

But environmentalists are not the only ones who’ve criticized the choice of location. An expanded port, built to facilitate ammonia exports, will sit immediately adjacent to a site that housed a labor and extermination camp during Namibia’s 1904–1908 genocide, in which tens of thousands of Nama and Herero people were killed by German soldiers during a period of resistance to colonial rule. A 2024 report commissioned by Nama and Herero leaders argues that the extension of port infrastructure woul

California’s Salton Sea Is Emitting Way More Toxic Gas Than We Thought

California’s largest and most-polluted lake, the Salton Sea, is exuding hydrogen sulfide, a noxious gas, at rates that greatly exceed the state’s air quality standards. Alarmingly, a new study finds that California’s air quality monitoring systems may be severely underestimating how much toxic pollution is reaching people living near the lake. Hydrogen sulfide, which smells like rotten eggs, is linked to a host of respiratory and neurological symptoms. The new study, published in the journal Ge
