Clean Energy to Build New Hydrogen Station for Orange County Transportation Authority’s Expanding Zero-emission Bus Fleet

Key Terms

hydrogen fuel cell technical

A hydrogen fuel cell is a device that generates electricity by combining hydrogen and oxygen, producing water and heat instead of burning fuel — think of it like a battery that runs as long as you supply hydrogen. Investors care because fuel cells can reshape energy and transportation markets by lowering emissions, changing operating costs, creating new revenue streams, and exposing companies to technology, supply-chain and regulatory risks or incentives.

liquid hydrogen technical

Liquid hydrogen is hydrogen gas cooled to extremely low temperatures so it becomes a dense, cold liquid for storage and transport; think of it as freezing a gas into a compact, highly energy-rich fuel that needs insulated tanks like a thermos. Investors care because it can serve as a clean energy or industrial feedstock with high energy-per-weight but also brings costly handling, storage and infrastructure requirements that affect project economics, safety risk and regulatory approval.

compressed natural gas technical

Compressed natural gas (CNG) is methane stored under high pressure in tanks so it can be used as a fuel for vehicles, power generators and industrial equipment; think of it like keeping a fizzy drink in a pressurized can so the gas can be released to do work. It matters to investors because CNG can be a lower‑cost, lower‑pollution alternative to gasoline or diesel, affecting fuel demand, fleet operating costs, infrastructure spending and regulatory risk across energy and transportation businesses.

renewable natural gas technical

Renewable natural gas is methane captured from organic waste—like landfills, farms, or wastewater—and cleaned to the same quality as conventional pipeline gas so it can be used for heating, electricity, or vehicle fuel. Investors care because it turns waste into a revenue-generating commodity, can qualify for carbon credits or government incentives, and can reduce a company's emissions profile, affecting long-term costs, regulatory risk, and market demand much like converting trash into sellable fuel.

Clean Energy hydrogen station construction site in Pomona, California

NEWPORT BEACH, Calif.--(BUSINESS WIRE)-- Clean Energy Fuels Corp. (NASDAQ: CLNE), a leader in construction of alternative transportation stations, announced it has been awarded a $27.5 million contract by Orange County Transportation Authority (OCTA) to design and build a new private hydrogen fueling station at OCTA’s Garden Grove bus base.

Clean Energy hydrogen station construction site in Pomona, California.

The new station will support the agency’s growing fleet of zero-emission hydrogen fuel cell buses. Under the contract, Clean Energy will provide design-build services for the hydrogen station and facility upgrades, as well as operations and maintenance services and liquid hydrogen fuel supply. The project is expected to be completed in 2028.

OCTA currently operates a fleet of hydrogen fuel cell, battery-electric and compressed natural gas (CNG) buses with plans to transition to a 100 percent zero-emission bus fleet by 2040, aligning with California’s Innovative Clean Transit (ICT) regulations. OCTA currently has 10 hydrogen fuel cell buses in service and expects to add 40 more by the time this fuel station is built.

"OCTA has built a reputation as a forward-thinking transit agency that continues to invest in clean transportation technology," said Alphonse Anderson, Senior Account Manager at Clean Energy. "As they expand their hydrogen fleet, we're honored to help deliver the infrastructure that will support those operations for years to come. Clean Energy is headquartered in Orange County and has built hydrogen stations for other Southern Californian transit agencies, so being selected to build OCTA's station locally makes this project especially meaningful for our team."

OCTA is one of the largest transportation agencies in Southern California, overseeing bus services across the county of over 3.1 million residents, as well as regional transportation planning, road improvements, and rail programs. The agency operates, maintains and fuels buses from four locations, one being the Garden Grove bus base, where the new hydrogen station will be built.
