Zero Emission Buses
The Future of Transit
AC Transit’s Zero Emission Bus Fleet
AC Transit has been a leader in advancing zero emission technology for more than 20 years. This April we mark the next phase of our transition to a 100% zero emission fleet with the delivery and launch of more than 40 new zero emission buses.
In our continued commitment to fighting climate change, we have invested in the cleanest bus fleet—21 GILLIG Battery Electric 40-foot buses and 20 New Flyer Xcelsior CHARGE H2™ hydrogen fuel cell 40-foot buses—with an all-new look. The 41 new buses join our current fleet of 26 zero emission buses, with many more on the way.
The new buses feature a refreshed look. Battery electric buses can be identified with vibrant violet decals, while hydrogen fuel cell buses feature a distinctive gold stripe. The new buses were purchased with generous grants provided by state, regional, and federal agencies.
By adding a new fleet of 100% clean air vehicles, we are bringing quieter, healthier, and cleaner transit to our communities.
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.
2040 Zero Emission Goal
In 2019, the California Air Resources Board (CARB) passed the Innovative Clean Transit Regulation, requiring all public transit agencies to transition to zero emission technologies by 2040. AC Transit is leading the way to a zero emission future by utilizing both battery electric and hydrogen fuel cell technology as we expand our fleet of zero emission buses.
