One of the nation’s largest hydrogen-powered transit fleets is seeking to switch to a cleaner — and local — fuel source as part of a federally funded clean hydrogen hub.
The Stark Area Regional Transit Authority, or SARTA, provides about 5,000 daily rides to commuters in the Canton, Ohio, area. A decade after federal grants helped it purchase its first hydrogen fuel-cell buses, the authority now has 22 such vehicles, making it the country’s fourth-largest hydrogen-powered transit fleet.
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.
Currently, the transit agency imports hydrogen — made from natural gas without carbon capture — by truck from Canada. Such “gray” hydrogen emits about 11 tons of carbon dioxide per ton of hydrogen produced. President Donald Trump’s threatened tariffs against Canada could also affect the cost and supply of hydrogen available to SARTA, although specific impacts are still unclear.
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.
Details could change as the project progresses, according to Enbridge spokesperson Stephanie Moore. Enbridge would own the hydrogen production and storage equipment.
Conrad estimated that the whole project will cost around $15 million, about 70% of which would come from federal funding under the 2021 bipartisan infrastructure law and other grants. It’s unclear, though, whether the Trump administration will renege on those commitments, even those which have already been formally obligated under contract.
“ARCH2 receives funding for this project through a contract issued through the U.S. Department of Energy’s Office of Clean Energy Demonstrations,” Moore said. “We have received no information outlining any modifications to that contract and therefore will continue moving forward on this project as planned.”
If the project can be completed, it will double SARTA’s supply of hydrogen, lower costs and emissions, and improve the transit system’s resiliency, Conrad said, noting that the agency has experienced occasional fuel delivery problems. Plus, domestic hydrogen production can support U.S. energy independence goals, he said.
A desire to switch to cleaner fuels and the costs per mile compared with diesel buses convinced SARTA to start buying fuel-cell buses in 2014. Today, it has 17 large buses and 5 smaller paratransit vehicles that run on fuel cells, which split hydrogen into protons and electrons and send them along separate paths. The electrons provide an electric current, while the protons wind up combining with oxygen to make water.
California has had fuel-cell buses on the road for more than two decades, and other places that have embraced the vehicles in recent years include Philadelphia’s Southeastern Pennsylvania Transportation Authority and Maryland’s Montgomery County.
Sean O’Leary, a senior researcher for the Ohio River Valley Institute, said the planned project by SARTA and Enbridge would cut greenhouse gas emissions compared with current practices.
“Green hydrogen is … a lot better than gray,” O’Leary said. However, he’s skeptical whether fuel-cell buses are the vehicles he would choose today for transit systems to reduce emissions. “I would personally rather see them go to electric buses or even biodiesel, both of which would reduce emissions more and cost a … lot less.”
Conrad said SARTA would have liked to have started out using green hydrogen, but it wasn’t available in the marketplace a decade ago. Now that the technology has advanced, he thinks it’s time to make the switch to a cleaner source of hydrogen.
“Sometimes an industry just needs time to evolve. And I think that’s what we’re starting to see now,” Conrad said.
If all proceeds well, SARTA anticipates on-site hydrogen production could start as soon as 2028.
