- HERO WEC V1.0 - SolidWorks ModelThe attached zip file includes a SolidWorks pack-and-go assembly of NREL's HERO WEC (hydraulic and electric reverse osmosis wave energy converter) V1.0. This model does not include all aspects of the design (i.e. RO (reverse osmosis) system, electrical enclosure, hose, cable) it only includes the WEC and PTO (power take-off) design.1Licence not specifiedabout 1 year ago
- HERO WEC V1.0 - WEC-Sim ModelThis zip file contains the files that are needed to simulate NREL's HERO WEC (hydraulic and electric reverse osmosis wave energy converter). This requires the user to have already installed WEC-Sim. In addition to the standard toolboxes that are required to run WEC-Sim the user will also need the Simscape Fluids and Simscape Driveline packages. In the zip file you will find the following: - HEROV1_HPTO.slx: Simulink-based WEC Sim model of the first gen (V1.0) Hydraulic PTO (power take-off) that was designed for the HERO WEC - wecSimInputFile.m: Input file needed to run the model - userDefinedFunctionsMCR.m: MCR (multi condition run) script that is needed if a use wants to simulate multiple wave conditions. - geometry (folder): Includes the geometry file that is needed for visualization - hydroData (folder): Includes the required WAMIT data to run WEC-Sim1Licence not specifiedabout 1 year ago

- Community Resilience through Low-Temperature Geothermal Reservoir Thermal Energy StorageSubmitted data include simulations related to underground thermal battery (UTB) simulations described in Modeling and efficiency study of large scale underground thermal battery deployment, presented at GRC, October 2021. The UTB is comprised of a tank of water, a helical heat exchanger in the center of tank and connected to a water source heat pump, and a phase change material (PCM). Compared to a conventional VBGHE, the UTB is designed to be installed at a much shallower depth, therefore, with a cheaper cost. In addition, the GSHP efficiency is improved due to natural convection of water and additional load capacity provided by PCM. The goal of this study is to explore factors that may affect the efficiency of large-scale UTB deployment. The simulations found in this submission relate to the report on UTB deployment.1Licence not specifiedabout 1 year ago
- Snake River (Idaho) Geothermal Drilling Project: Innovative Approaches to Geothermal ExplorationThe goal of our project was to test innovative exploration technologies using existing and new data, and to ground-truth these technologies using slim-hole core technology. The slim-hole core allowed us to understand subsurface stratigraphy and alteration in detail, and to correlate lithologies observed in core with surface based geophysical studies. Compiled data included geologic maps, volcanic vent distribution, structural maps, existing well logs and temperature gradient logs, groundwater temperatures, and geophysical surveys (resistivity, magnetics, gravity). New data included high-resolution gravity and magnetic surveys, high-resolution seismic surveys, three slimhole test wells, borehole wireline logs, lithology logs, water chemistry, alteration mineralogy, fracture distribution, and new thermal gradient measurements. Drill holes are located at Kimama, Kimberly, and Mountain Home Air Force Base in Idaho.1Licence not specifiedabout 1 year ago
- Testing LCM on a Large Scale for Geothermal Drilling Applications Using a Novel Experimental SetupRheology data obtained from flow loop tests, performed using different lost circulation materials (LCM) to study their effect on fluid rheology and wellbore hydraulics. The sealing performance of different LCM was tested using different fracture sizes. Five academic papers / reports derived from this research are also presented.1Licence not specifiedabout 1 year ago
- Project Hotspot - Petrology, Geochemistry and Stratigraphy of the Kimama core hole, Snake River Plain, IdahoThis submission contains links to two open source published papers on the Kimama core hole, Project Hotspot. "Volcanic stratigraphy and age model of the Kimama deep borehole (Project Hotspot)" - Basalts erupted in the Snake River Plain of central Idaho and sampled in the Kimama drill core link eruptive processes to the construction of mafic intrusions over 5.5 Ma. "Evidence for cyclical fractional crystallization, recharge, and assimilation in basalts of the Kimama drill core, central Snake River Plain, Idaho: 5.5-million-years of petrogenesis in a mid-crustal sill complex" - Project Hotspot recovered almost 2 km of continuous drill core from the Kimama borehole, located in central Idaho on the axial volcanic zone. The Kimama drill core represents the most complete record of mafic volcanism along the Yellowstone-Snake River Plain hotspot track.1Licence not specifiedabout 1 year ago
- Utah FORGE Project 3-2535 Report for Milestone 5.1Report on possible geodetic signature of the 3 stimulations in April 2022 as well as a comparison with existing InSAR data gathered over the site before, during, and after the stimulation.
