Biomass & Biofuels
For Hawaii, biomass has long been targeted as a major renewable energy resource. HNEI has completed a range of assessments, such as the Bioenergy Master Plan for the State of Hawaii.
Liquefied Natural Gas (LNG)
To investigate the economic, technical and policy implications concerning LNG as an option for Hawaii, HNEI commissioned FACTS, Inc. (FACTS Global Energy) to complete a report. LNG may have some possible environmental and economic advantages for Hawaii's near-term energy future, as part of the state's potential energy mix.
Integration of high levels of variable wind and solar photovoltaic (PV) resources has been assessed for the electrical grid systems of Oahu and Maui. Additionally, interconnection of the counties’ grid systems has been assessed to quantify the value of operating as one combined system, considering several possible future scenarios with different mixes of renewable generation.
PV output varies with location and environmental factors, so HNEI is assessing several test sites to evaluate emerging and commercial materials and systems, along with assessing solar resources.
Wave energy resources as well as ocean thermal energy gradients (the temperature differential between deep and shallow waters) have been modeled, assessed and continue to be measured.
