Hawaii Hydrogen Power Park : In 2002, HNEI received an award from the USDOE to implement the Hawaii Hydrogen Power Park project, and Technology Validation effort to demonstrate various elements of the value chain for a practical renewable hydrogen energy system. This project has evolved since 2002, and now includes: 1) infrastructure deployment on Oahu and the Big Island, 2) over $8MM in funding from sources including USDOE, ONR, NRL, and the State of Hawaii supporting both DOD and civilian transportation projects, and 3) new partners including Marine Corps Base Hawaii, the Hawaii Volcanoes National Park, the Hawaii Mass Transit Agency, Hawaii Center for Advanced Transportation Technology, and Puna Geothermal Ventures, among others.
Hydrogen Energy System as a Grid Management Tool : A joint USDOE-DOD technical validation project to demonstrate the use of electrolyzer technology to simultaneously produce hydrogen for fuel while providing grid management services. Hydrogen produced at the geothermal plant will be used to fuel fuel-cell electric buses operated by the County of Hawai‘i Mass Transit Agency and Hawai‘i Volcanoes National Park.
Marine Corps Base (MCB) Hawai‘i Hydrogen Fueling Station : A technical validation project supporting the development of 700-bar (10,000-psi) hydrogen “Fast Fill” fueling infrastructure in support of the operation of General Motors (GM) Equinox Fuel Cell Electric Vehicles (FCEVs) at MCB Hawaii to enable the US Navy/Marine Corps to conduct technical evaluations and gain experience in the operation of FCEVs utilizing hydrogen fuel.
Hydrogen Separation : Experimental investigation of a bench-scale pressure swing adsorption unit to evaluate separation strategies for hydrogen from pipelined synthetic natural gas, from product gas from the HNEI fluidized bed gasification system, and other sources.
Analysis of LPG Reforming Options : Evaluation of LPG reforming as a potential source of hydrogen for distributed fuel cell power applications in Hawaii.
Hydrogen Production from Waste Resources: Investigation of thermochemical hydrogen production strategies from waste resources.
Use of PEM Fuel Cells for Helium Recovery : Engineering design, modeling, and testing of a PEM fuel cell based separation system for the recovery of high purity helium (He) from mixed hydrogen/He streams. Project scope includes the design, build, and testing of full-scale hydrogen separation reactors for system integration.
Characterization of Fuel Cell Performance with sub-ppm CO Contamination: Experimental program to measure the impact of CO in hydrogen at practically low concentrations using high resolution gas sampling and innovative analysis techniques on PEM fuel cell performance.
Photoelectrochemical hydrogen production : the goal of this research program is to develop efficient and durable photocatalytic materials to produce hydrogen fuel via solar-assisted (“wireless”) water splitting process.
Acoustic enhanced electrolyzer: this research project aims to establish if the water splitting efficiency of an electrolyzer can be improved by the use of acoustic cavitation.
