The Redding Area Bus Authority (RABA) was provided grant funding to convert its entire transit fleet to Zero Emission Bus (ZEB) by 2040 to meet California Air Resources Board's (CARB’s) Innovation Clean Transit (ICT) Regulations. This project aims to evaluate the feasibility of both battery and hydrogen fuel cell propulsion transit systems, including how conversion to either clean technology would impact transit service, and determine the upgrades to RABA’s facilities for fueling/charging and vehicle maintenance.
