The transition to zero emission bus (ZEB) fleets is accelerating. Two prevalent ZEB options that are often compared to each other are battery electric buses (BEBs) and fuel cell electric buses (FCEBs) fueled by green hydrogen. Hydrogen is labelled as green when it is produced by electrolysis powered by renewable electricity. From the perspective of a bus fleet operator or regional authority interested in replacing a conventional diesel bus fleet with one of these new technologies, it can be unclear which combinations of BEBs and FCEBs are most suitable in terms of cost, emission reduction, and capability to maintain regular operation of the bus fleet. This work develops the Enabling Support Tool (EST), an easy-to-use model that can assess the trade-offs between BEBs and FCEBs in terms of their technical performance, required infrastructure, cost, and emissions reduction potential. Using a novel input process that does not require complex drive-cycle data, the EST allows the user to quickly investigate the feasibility of a mixed fleet of BEBs and FCEBs, considering the effects of local climate conditions, road gradient, and varying bus payload on the daily range of BEBs. This enables users to explore the feasibility of different combinations of BEBs and FCEBs and thus guide cost-effective full fleet decarbonisation.
