California-based US Hybrid Corporation has been awarded a contract by the Hawaii Center for Advanced Transportation Technologies (HCATT) for the design, integration and delivery of its H2Ride Fuel Cell Plug-In Shuttle Bus for operation by the County of Hawaii Mass Transit Agency’s (MTA) HELE-ON Big Island bus service. The project is funded by the State of Hawaii and Office of Naval Research via the Hawaii Natural Energy Institute (HNEI).
Integrated at US Hybrid’s Honolulu facility, the 25-passenger shuttle bus utilizes a 30 kW fuel cell fueled by a 20 kg hydrogen storage and delivery system. The fuel cell and 28 kWh lithium-ion battery pack power the vehicle’s 200 kW powertrain, air conditioning, and auxiliary systems. Onboard batteries are recharged by regenerative braking as well as grid charging. The US Hybrid fuel cell, powertrain, and vehicle controller optimizes power delivered by the energy storage and fuel cell power plant.
Such shuttle buses have been in operation in Hawaii at the Air Force’s Joint Base Pearl Harbor-Hickam and the Hawaii Volcanoes National Park. The new H2Ride Fuel Cell Plug-In Shuttle Bus is scheduled for deployment with Hawaii MTA in early 2015.

US Hybrid Corporation, a global supplier of medium- and heavy-duty electric and hybrid powertrain power conversion components, executed a global licensing agreement with United Technologies Corporation (UTC) in January of this year to commercialize UTC’s proven Proton Exchange Membrane (PEM) fuel cell technologies. (Earlier post.)
US Hybrid has been a key supplier of balance-of-plant components such as cathode air blowers, DI pumps and power converters to UTC and other fuel cell suppliers for over a decade. US Hybrid thus added fuel cell production to its core competencies of system design, integration and operation of fuel cell buses, trucks, military and specialty vehicles, as well as supporting fuel cells with component electronics.
Founded in 1999, US Hybrid Corporation specializes in the design and manufacture of integrated power conversion components for fuel cell, electric, and hybrid medium- and heavy-duty vehicles, as well as for renewable energy generation and storage. US Hybrid offers comprehensive engineering expertise and experience in vehicle powertrains and components, including DC-DC converters, energy management systems, high-performance AC motors, and controllers.
Managed by HTDC, HCATT has organized public/private partnerships between the federal government and private industry to develop advanced low emission and zero emission vehicles centered on electric drive technologies. Additionally, HCATT has entered into a partnership with the Hawaii Natural Energy Institute and Hawaii Volcanoes National Park to introduce zero emission, hydrogen fuel cell/battery powered hybrid electric buses into the park to support environmentally friendly tours for the millions of annual visitors to the park.
The Hawaii Natural Energy Institute is an organized research unit of the School of Ocean and Earth Science and Technology (SOEST) of the University of Hawaii at Mānoa (UHM). The Institute performs research, conducts testing and evaluation, and manages public-private partnerships across a broad range of renewable and enabling technologies to reduce the State of Hawaii’s dependence on fossil fuel for the benefit of the citizens of Hawaii.
