The U.S. Department of Energy (DOE) is proposing to provide federal funding to the University of Hawaii to address the overarching theme of uncertainty quantification and reduction for geothermal exploration, specifically through the development of Geothermal Play Fairways. A play fairway analysis defines levels of uncertainty with respect to the presence and utility of geothermal system elements, and translates them into maps to high grade the geographic area over which the most favorable combinations of heat, permeability, and fluid are thought to extend. Previous NEPA Determinations (GFO-FOA0000841-001, GFO-0006729-002, and GFO-0006729-003) reviewed Budget Periods (BP) 1 and 2 of the project. This NEPA review is for BP3 activities.

University of Hawaii project activities in BP3 would be for the collection of scientific data from a well that is being drilled on Lāna‘i separate from this DOE project. The Lāna‘i drilling activity is being completed by a private entity (Pūlama Lāna‘i) that is responsible for the drilling of the well and all associated permitting and regulatory process activities. The well would be drilled regardless of the scientific data collection activities proposed in this award, therefore drilling activities are not considered a connected action to the DOE project and will not be reviewed as part of this award.
