Zero-Emission Bus Program

As part of its plan to convert the OC Bus fleet to 100 percent zero-emission technology by 2040, OCTA is investing in both plug-in battery-electric buses and hydrogen fuel-cell electric buses. This pilot will help determine which technology - or mix of technologies - will help bring even cleaner air quality to Orange County.

These modern electric buses operate on routes throughout various parts of the county.

In addition to being friendly to the environment, these new buses are friendly to riders. Both our plug-in battery-electric buses and hydrogen fuel-cell electric buses are packed with features that allow riders to journey relaxed, productive and entertained. Learn more about these sleek, quiet buses that keep passengers comfortable and connected.

OCTA's Zero Emission Bus (ZEB) Program aligns with California's Innovative Clean Transit Rule, a first-of-its kind regulation in the U.S. that sets a goal for public transit agencies to gradually transition to 100 percent zero-emission bus fleets by 2040.

Environmental Benefits

OCTA's commitment has resulted in:

  • OCTA was the first large public transportation agency in Southern California to operate a hydrogen fuel-cell electric bus to help protect the environment.
  • Buses powered by fossil fuel buses emit air pollutants that produce smog and greenhouse gases. Hydrogen fuel-cell electric buses emit only water, which means cleaner air, less global warming, and healthier, quieter neighborhoods.
  • OCTA's hydrogen fueling station, the largest in the country, was funded in part by California Climate Investments, a statewide initiative that puts billions of cap-and-trade dollars to work reducing greenhouse gas emissions, strengthening the economy and improving public health and the environment - particularly in disadvantaged communities.

Driving Toward a Zero-Emission Future
OCTA is committed to a 100 percent zero-emission bus fleet by 2040. Along the way, we’re testing two types of buses to see which technology, or mix of technologies, is best for Orange County. Another bonus: These electric versions have features that make bus travel better than ever.
OCTA Debuts Nation's Largest Hydrogen Fueling Station
On Jan. 31, OCTA joined local, state and federal officials in showcasing its continuing efforts to use zero-emission transportation technology for a balanced and sustainable transit future.
Ten Zero-Emission Plug-in Buses to Join OCTA Pilot Program
OCTA is purchasing 10 plug-in battery-electric buses for a pilot program to test how the buses perform on Orange County streets. The contract with New Flyer of America, Inc. is for $10.4 million and grant funding will help pay for the purchase.
