The company commissioned a 1.25MW electrolyser system at the Farmington Hills site to produce hydrogen for testing its electrolyser stacks and fuel cells.

It mirrors a 2.5MW system installed at the firm’s Bamberg facility, where it makes the stacks in Germany, which came online last November.

With the US electrolyser now operational, Bosch said its Hybrion stacks are available to North American buyers. “These systems are provided through our integration partners,” it said.

Bosch launched its Hybrion stacks last April with initial plans to supply system integrators like Neuman & Esser, AKA Energy Systems, and Andritz, as well as Chinese electrolyser maker Hygreen Energy.

The company hasn’t confirmed its stack-making capacity. However, last March H2 View was told the company would take a “stepwise” approach – tying expansion to orders. It has not indicated whether it has manufacturing capabilities for the technology in the US.

Bosch’s Senior Vice-President, Electrolyzer Solutions, Carola Ruse, said the Farmington Hills plant showed the company’s “long-term commitment” to supporting the growth of the North American hydrogen market.

However, this expansion comes as the US market has become a far more uncertain environment for green hydrogen companies over the past 24 months.

In the first year of the second Trump Administration, the flagship 45V clean hydrogen production tax credit was shortened by five years, two of the seven regional hydrogen hubs lost funding, and the remaining five are still awaiting disbursement.

Additionally, with growing power demand from data centres, other companies have told H2 View to access low-cost renewable power is becoming tougher, potentially undermining green hydrogen economics.

Bosch bet heavily on hydrogen in the early 2020s, having started mass production of PEM fuel cells, developing hydrogen combustion engine components, and stationary fuel cell systems.

However, the company’s fuel cell pilot truck OEM Nikola filed for bankruptcy earlier this year, and waved off its stationary fuel cell programme due to low demand.
