‘H2Hubs’ will fuel American hydrogen production in $8 billion program - The Verge

The Department of Energy launched an $8 billion program to develop hubs across the US for clean hydrogen. Clean energy experts, meanwhile, are wary about what kinds of projects the DOE considers because some are dirtier than others.

The Department of Energy kicked off a new $8 billion program yesterday to develop a network of hubs for producing hydrogen as a clean fuel. It’s a milestone for one of the Biden administration’s most contentious strategies for tackling climate change.

Hydrogen has the potential to slash emissions from some of the industries that are the hardest to clean up. It might replace coal used in making steel or fossil fuels that power diesel trucks and cargo ships. When burned, it produces water vapor instead of greenhouse gas emissions (although it can still contribute to nitrogen oxide pollution in the air).

The tricky part is that not all hydrogen is created the same way and can come with different benefits and pitfalls. At the moment, most hydrogen is made using gas. To make hydrogen from gas, methane reacts with high-temperature steam under high pressure. That process releases carbon dioxide, and then there’s the threat to the climate that comes from methane leaks across the entire gas industry. Methane is an even more potent greenhouse gas than carbon dioxide.

So, the Biden administration needs to clean up hydrogen production before it can use hydrogen to decarbonize other industries. The DOE laid out part of its plan to clean up that process yesterday when it filed a Notice of Intent (NOI), a document saying that it plans to announce a funding opportunity in September or October to develop clean hydrogen hubs, which it calls “H2Hubs.”

The Bipartisan Infrastructure Law provides funding for at least four hubs; the NOI says the DOE is considering funding between six and 10 hubs to start its program. Of those hubs, at least one is supposed to make hydrogen using renewable energy. Another hub is supposed to power hydrogen production with nuclear energy. And, at least one hub should be able to show it can make clean hydrogen from fossil fuels by pairing it with technologies that capture and sequester carbon dioxide emissions. But the DOE also says it will look for at least two hubs in regions with “abundant natural gas resources,” which could lead to more H2Hubs running on fossil fuels than renewable energy.
