Federal Transit AdministrationUS Transportation CollectionThe U.S. Federal Transit Administration (FTA) funds a variety of research projects that support the commercialization of zero-emission bus technology. Recent programs include the National Fuel Cell Bus program, the Transit Investments for Greenhouse Gas and Energy Reduction (TIGGER) program, and the Low or No Emission Vehicle Deployment (Low-No) program. To evaluate projects funded through these programs, FTA has enlisted the help of the National Renewable Energy Laboratory (NREL) to conduct third-party evaluations of the technologies deployed under the FTA programs. NREL is a U.S. Department of Energy (DOE) national laboratory focused on renewable energy and energy efficiency research. NREL works with the selected agencies to evaluate the performance of the zero-emission buses compared to baseline conventional buses in similar service. The evaluation effort will advance the knowledge base of zero-emission technologies in transit bus applications and provide \u201clessons learned\u201d to aid other fleets in incrementally introducing next generation zero-emission buses into their operations. NREL developed this preliminary results report to quickly disseminate evaluation results to stakeholders. Detailed evaluation results will be published in future reports
