Hydrogen-powered Buses Coming to Big Island

Hawaii Island could be less than a year away from having some of the first hydrogen-powered buses in the state on its roadways. As part of a pilot project spearheaded by the Hawaii Natural Energy Institute, three shuttle buses will be converted to hydrogen power. Two will be provided to Hawaii Volcanoes National Park, while the third goes to the Hawaii County Mass Transit Agency, also known as Hele-On.  (June 24, 2014.)

BATTERY TECHNOLOGY

HNEI researchers conduct research, testing and modeling of battery technology to further the understanding of their performance and durability for use in electric vehicles (EVs), renewable energy storage applications, and unmanned vehicles for the Department of Defense.  The effort is conducted in two laboratories, the Electrochemical Power Systems Laboratory (EPSL) focused on emerging battery technology, and the Hawaii Sustainable Energy Research Facility (HiSERF) batteries for fuel cell and electricity grid applications, and for EVs.

HNEI researchers at EPSL conduct basic and applied research, testing and modeling to develop advanced battery system diagnostic and prognostic capabilities seeking to develop better protocols for management of batteries and battery charging.

Researchers at HiSERF have developed characterization techniques to elucidate mechanisms controlling fuel cell degradation.  These techniques along with modeling and prognostic techniques developed in EPSL are now being applied to model, test and validate the performance of a range of battery technologies.  Conditions are simulated for a range of applications, including EV charging and discharging, fuel cell systems for commercial and military vehicles, and Megawatt-scale batteries for the electricity grid.  Results lead to increased understanding of battery performance and durability, along with operating conditions to extend battery life.
