The DOTs Federal Transit Administration (FTA) National Fuel Cell Bus Technology Development Program (NFCBP) focused on advancing the commercialization of 40-foot, heavy-duty, fuel cell transit buses. The Program funded the development of commercially viable fuel-cell bus technologies and related infrastructure througha competitive grant process with a non-federal cost-share requirement. The NFCBP aimed to accelerate the adoption of electric drive technologies - battery electric, hybrid electric, and hydrogen fuel cell buses. The Program aimed to support the development and demonstration of fuel cell buses, components and technologies, primarily projects with an ability and intent to commercialise, with some funds directed towards high risk, innovative technologies. Among its goals was increased public acceptance of fuel cell vehicles.
