Pre-Feasibility and Business Case — Hydrogen Development

JRG Energy prepared a pre-feasibility study evaluating the technical and commercial practicality of utilising existing hydrocarbon assets for hydrogen production. Existing asset data were analysed against realistic grey, blue and green hydrogen business scenarios. The final deliverable provided a comprehensive business case on the feasibility and profitability of hydrogen utilisation across the existing asset portfolio. 

Toulouse Matabiau Geothermal Technical Expert Review

JRG Energy was engaged by SAF-Environnement to conduct a technical expert review (Type M.2.2) of a geothermal district heating project in the Toulouse Matabiau area — a Segment 2 zone with less well-characterised geology. The review assessed the project dossier against current regulations and best practices to determine flow rate and temperature characteristics for the guarantee convention, identify compliance gaps, uncertainties, and risks, and […]

Philippines Geothermal Greenfield Due Diligence

JRG Energy conducted a due diligence assessment of a geothermal greenfield opportunity for INPEX in the Philippines. The scope encompassed a comprehensive literature review, fieldwork including fluid sampling and chemical analysis, geochemical modelling of thermal manifestations, review of magnetotelluric and gravity geophysical surveys, and recommendations for further assessments to advance the project towards a development decision.

South Brawley Geothermal Lithium Due Diligence

JRG Energy conducted technical due diligence of the South Brawley / NewRiver geothermal lithium prospect in the Salton Sea geothermal fields — one of the world’s most productive geothermal regions, with over 740 MWe of installed capacity across four fields. The assessment evaluated the geothermal and lithium resource potential of this actively spreading pull-apart basin setting, supporting Leo […]

Peninsula Hot Springs Vendor Due Diligence

JRG Energy were engaged to prepare a vendor due diligence sales assessment for Peninsula Hot Springs, a leading geothermal mineral springs and wellness destination offering over 70 bathing and wellness experiences. The assessment provided prospective purchasers with a comprehensive technical overview of the site’s geothermal water infrastructure, supporting the proposed divestment of the facility.

Brighton Thermal Gradient Well & Hot Springs Feasibility

For the development, JRG Energy designed and project-managed the construction of a ~600 m thermal gradient well, acquiring core and running wireline surveys to fully characterise the target formations. We then delivered specialist consulting to determine the technical and commercial viability of deep coaxial closed-loop, shallow closed-loop, and shallow open-loop geothermal as the heating and mineral water supply for the proposed facility.

Eastland Generation Technical Due Diligence

JRG Energy conducted a technical due diligence for Obayashi Corporation focusing on subsurface elements of Eastland Generation’s geothermal assets at Kawerau. The review was instrumental in Obayashi’s decision to acquire a 50% stake in Eastland Generation. It assessed current resources available for power generation, alignment with the owner’s business plan, potential additional capital expenditures, and […]
