Hydrogen fuel is expensive to produce, and up to 50% of the fuel can be lost at some older hydrogen fueling stations in California due to boil-off and other issues. Bosch has developed a new cryogenic hydrogen pump that can transfer super-cold liquid hydrogen with a loss of only 5% or less, aiming to significantly improve the efficiency of hydrogen fueling.
Why it matters
Reducing fuel losses at hydrogen stations is critical to making hydrogen a more viable and cost-effective alternative fuel, especially for heavy-duty vehicles like trucks. High fuel costs and wastage have been barriers to wider hydrogen vehicle adoption, so innovations like Bosch's cryogenic pump technology could help make hydrogen more practical and affordable.
The details
Bosch's new CryoPump Module was installed at a hydrogen station serving a fleet of Hyundai XCIENT fuel-cell trucks at the Port of Oakland in 2025. The direct-fill pump can transfer liquid hydrogen at -420°F with up to 95% efficiency, eliminating the need for costly storage vessels, chillers, and valve panels that contributed to high fuel losses at older stations. The versatile pump can deliver hydrogen compressed to 350, 700, or even 900 bar, enabling fast fueling for a range of vehicle types.
- Bosch installed the CryoPump Module at the FirstElement hydrogen station in Oakland in the fall of 2025.
- Bosch held a Hydrogen Technology Day event at its Michigan headquarters on March 17, 2026 to showcase its new hydrogen innovations.

What they’re saying
“The new Bosch pumps, which are bathed in cold hydrogen, look very promising. They eliminate high pressure in the tank, and they don't need to be primed.”
— Jaimie Levin, Director of West Coast Operations, Center for Transportation and the Environment
“Hydrogen can change the world. We've had 30 years of research in hydrogen, whose only emission is water.”
— Jordan Choby, Vice President for Powertrain, Toyota Motor North America
What’s next
Bosch plans to integrate its hydrogen electrolyzer into the grid to help utilities handle peak loads, in addition to continuing to develop and deploy its cryogenic hydrogen pump technology at more fueling stations.
The takeaway
Bosch's new cryogenic pump technology represents a significant innovation that could help make hydrogen a more viable and cost-effective fuel, especially for heavy-duty vehicles, by dramatically reducing the fuel losses that have plagued older hydrogen fueling infrastructure.
