Zero Emission Buses
AC Transit Receives $25.5MM Through Coveted FTA Grant Award
We’ve been awarded $25.5 million from the prestigious 2023 Federal Transit Administration’s Bus and Low-and No-Emission Grant Awards! This coveted award will allow us to acquire 25 cutting-edge hydrogen fuel cell electric buses, replacing traditional diesel engines and accelerating us toward CA's requirement to be fully zero emission by 2040.
The Future of Transit: AC Transit’s Zero Emission Bus Fleet
AC Transit is investing in our planet and the future by leading the fight against climate change. Since 1999, AC Transit has been committed to exploring conversion to zero emission technologies—first with hydrogen and now battery-powered buses. AC Transit is moving from vision to reality and is actively converting one of the largest bus fleets in California to 100% clean fuels. By the end of 2023, 10% of AC Transit’s fleet will be zero emission clean air buses. By 2040, 100% of AC Transit’s fleet will be zero emission buses. Learn how we are moving to a 100% zero emission fleet. This transition gets us closer to achieving climate change goals while improving the air you and your family breathe every day.
- Jobs: ZEBs bring good paying green jobs to our community.
- Better Ride: Compared to diesel technology, ZEBs reduce fatigue because of reduced noise and vibration. It’s smoother for riders too!
- Quieter: ZEBs are quiet and reduce ambient noise while traveling through the East Bay’s residential neighborhoods.
- Cleaner: ZEBs are proven to be an effective way for communities to reduce their carbon footprint. They have no tailpipe emissions—adios diesel exhaust gases!
- Healthier: ZEBs bring cleaner air to our communities, reducing particulate matter concentrations that can result in increased asthma rates and other negative health impacts.
Zero Emission Buses on the Road
- Our Zero Emission Bus (ZEB) program generated over 5 million miles and eliminated more than 12,800 metric tons of CO2.
- 43 ZEBs: 36 Hydrogen Fuel Cell Electric and 7 Battery Electric - Buses.
- Oakland: vapor compression hydrogen station, with 9,000 gal hydrogen storage tank.
- Six 62.5kW battery chargers.
- Emeryville: liquid compression hydrogen station with 15,000 gal hydrogen storage tank.
- ZEB CO2 reduction in various greenhouse gas equivalents:
- 23,841 Gallons of gasoline consumed
- 234,379 Pounds of coal burned
- 492.7 Barrels of oil consumed
- 41.23 Homes’ electricity use for one year
- 2.805 Tanker trucks worth of gasoline
Capital and Operating Progress Report
The Capital and Operating Progress Report expands the evaluation of the Zero Emission Bus (ZEB) technologies beyond the initial 5X5 control fleet and includes the District’s ZEB Program capital investment since inception and the financial forecast needed to deliver the full fleet transition.

History of Leadership
AC Transit has a proud history of embracing environmental technology in our efforts to better serve our neighborhoods and has long been a recognized leader in this field, both nationally and internationally. Our first hydrogen fueling facility was opened in November of 2002 at our Richmond Division to operate a single 30-foot fuel cell electric bus. In 2006, we launched our first-generation fuel cell electric bus pilot program, operating three vehicles and a station out of our East Oakland Division. In 2010, we added 13 second-generation fuel cell electric buses to the fleet and opened a second hydrogen fueling station at our Emeryville Division. A solid oxide stationary fuel cell was added to our East Oakland Division in 2013. Then, the following year, we opened a new hydrogen fueling station on the site. In 2017, our fuel cell power plants surpassed the Department of Energy and Federal Transit Administration’s target numbers of 25,000 hours of operation.
Then in 2019, AC Transit embarked on a true side-by-side comparison—incorporating five battery electric buses and seven charging stations into our expanding fleet of ZEBs. We will be running hydrogen and battery electric vehicles in identical service to collect real-world performance data for comparison—and to determine which technology performs better to meet the needs of our service as we move towards a complete zero-emission fleet by 2040.
