Montgomery County, Maryland, is getting a new green hydrogen bus depot featuring rooftop solar arrays and on-site green hydrogen production. A public/private partnership project, it will become the largest self-sustaining bus depot in the entire US. The new fuel cell buses will go into service in 2025 and will be powered by the green hydrogen produced at the depot. This is a major step forward for the county as it moves towards a cleaner, more sustainable transportation future.
Montgomery County, Maryland, is a densely populated county just outside Washington, DC. The county has over 1 million people and a bus, train, and car transportation system. The county is committed to reducing emissions from transportation, and the green hydrogen bus depot is a major step forward in that effort.
What is a green hydrogen bus depot?
A green hydrogen bus depot is a facility that produces and stores green hydrogen to fuel buses. Green hydrogen is produced using renewable energy, such as solar or wind power, instead of methane. This makes it a clean and sustainable alternative to fossil fuels like diesel.
Why is it Important?
There are several reasons why a green hydrogen bus depot is important. First, it can help to reduce emissions from transportation. Transportation is a major source of emissions in the US, and switching to green hydrogen can help to reduce those emissions. Second, a green hydrogen bus depot can help to create jobs. The construction and operation of the depot will create jobs in the construction, engineering, and operations sectors. Third, a green hydrogen bus depot can help to promote innovation. The development and deployment of green hydrogen bus depots will help to advance the technology and make it more affordable.
The Montgomery County, Maryland, green hydrogen bus depot will be located at the county’s Equipment Maintenance and Transit Operation Center (EMTOC). A 5+ MW solar array will power the depot and will have the capacity to produce up to 1,000 kilograms of green hydrogen per day. The green hydrogen will fuel 13 fuel cell buses, which will go into service in 2025. The depot is expected to cost $15 million to build and operate.
How the depot will work:
- The solar array will generate electricity.
- The electricity will be used to power an electrolyzer.
- The electrolyzer will split water into hydrogen and oxygen.
- The hydrogen will be stored in tanks.
- The buses will refuel with hydrogen from the tanks.
There are several benefits to using green hydrogen for buses:
- Green hydrogen is a clean and sustainable fuel.
- Green hydrogen is available 24/7, unlike electricity from the grid.
- Green hydrogen can be used to fuel buses of all sizes.
Challenges of using green hydrogen for buses:
- Green hydrogen is currently more expensive than diesel fuel.
- The infrastructure for producing and distributing green hydrogen is not yet widespread.
The Montgomery County, Maryland, green hydrogen bus depot is a major step forward for the future of transportation. The depot demonstrates that it is possible to operate a fleet of buses using clean and sustainable fuel. The depot is also expected to help reduce transportation emissions and create construction, engineering, and operations jobs.

Government is Providing Green Incentives
The federal government will provide several incentives to help Montgomery County, Maryland develop and deploy the green hydrogen bus depot. These incentives include:
- The Inflation Reduction Act of 2022 provides tax credits for producing green hydrogen.
- The Infrastructure Investment and Jobs Act provides funding for constructing hydrogen refuelling stations.
