Ohio transit agency to switch to green hydrogen for fuel cell buses

The vehicles emit only water vapor and warm air as exhaust, reducing air pollution in the neighborhoods where they run. But producing and transporting hydrogen for the fuel cells can be a significant source of climate emissions, which is why SARTA is partnering with energy company Enbridge and the Appalachian Regional Clean Hydrogen Hub, or ARCH2, on a plan to make the fuel on-site with solar power. “So it will be green,” said Kirt Conrad, SARTA’s CEO, referring to the use of renewable energy to power the production of hydrogen by splitting water.

SARTA had already worked with Dominion Energy on a compressed natural gas fueling station before Dominion’s Ohio utility company was acquired by Enbridge. When the Biden administration announced its regional clean hydrogen hub program in 2023, SARTA and the company joined others in Ohio, West Virginia, and Pennsylvania to pitch the ARCH2 hub. The hub was among seven selected by the Department of Energy in late 2023 and was awarded up to $925 million in funding last summer.

The plan is to install roughly 1,000 solar panels on about 10 acres of recently acquired land next to SARTA’s existing hydrogen fueling facility, said Conrad. That would generate up to 1 megawatt of electricity, powering an electrolysis facility that splits water into oxygen and hydrogen. Under the project’s current scope, the equipment would produce roughly 1 ton of hydrogen per day, enough to fuel 40 SARTA buses, Conrad added.
