CNG supplier Trillium to expand its services to include hydrogen fuel stations, as well as solar installation and EV charging infrastructure

The US’ Trillium CNG, a supplier of compressed natural gas (CNG) vehicle fuelling facilities, is expanding its services into hydrogen infrastructure.

The company announced on February 6 that it will design, build and maintain hydrogen fuel stations, as well as EV charging infrastructure, solar panels and microgrid design and construction.

Trillium will begin construction on its first hydrogen station for fuel-cell electric buses this summer, for the Orange County Transportation Authority’s (OCTA) Santa Ana, California, facility. The project will see the company install a station for transit buses, capable of supplying approximately 35kg of hydrogen per bus in 6 to 10 minutes simultaneously from two fuelling lanes.

OCTA’s bus fleet includes 10 hydrogen FCEV buses, but future growth could see the facility expanded to provide enough for a fleet of 50 buses. Infrastructure will be added to OCTA’s existing CNG fueling lanes, which were designed and built by Trillium in 2007.

“While compressed natural gas remains a high priority for Trillium, diversification of Customer needs, products and services within the transportation industry is driving our expansion,” said Bill Cashmareck, managing director of Trillium CNG.

Unlike some fuel stations, supplies for OCTA will be produced off-site. Air Products will supply and deliver liquid hydrogen, on a weekly basis to the facility, which is stored before being pumped and vaporised into high-pressure gas for delivery onto buses.

The project has also received funding from the California Air Resources Board (CARB) through the California Climate Investments program.

“California is proud to be on the forefront of the fight for clean air,” said Steve Cliff, CARB deputy executive officer. “Funds from the state’s landmark cap-and-trade program help forward-looking transit agencies like OCTA secure clean energy such as hydrogen to modernize and transform their fleets, enabling them to meet both our climate and air quality goals.”

Trillium says it plans to introduce EV charging stations at select “Love’s Travel Stops” locations later this year, followed by its new services in solar panel installation and microgrid design.


Trillium’s expansion is yet another example of fuel and downstream suppliers moving into electric infrastructure and ZEV supplies. While CNG will continue to have a place, more transit operators are opting for all-electric or hybrid buses as policies shift towards zero emissions.

As Trillium’s project with OPTA suggests though, early adopters may also have access to a wealth of new opportunities and funding sources.
