Ijen vs Zanskar: Blind Geothermal Energy Discovery and Development

Ijen’s Blind Geothermal System vs. Zanskar’s AI-Discovered Resources: Two Models for Finding Hidden Heat The geothermal industry is entering a new phase in which the most valuable resources may no longer be the fields marked by obvious hot springs, geysers, fumaroles, or steaming ground. Increasingly, developers are targeting “blind” or hidden geothermal systems,reservoirs that lack clear surface expressions but can still contain the temperature, permeability, and fluid needed for commercial power generation. Two examples illustrate how different parts of the industry are approaching this challenge. In Indonesia, the Blawan-Ijen geothermal field in East Java was developed through geological interpretation, magnetotelluric imaging, conceptual modelling, and drilling. The project is now operating commercially, with its first phase delivering approximately 35 MW to the Java grid under a 30-year power purchase agreement.  In the United States, Zanskar Geothermal & Minerals is using...

Vercana Electric Rig Advances Geothermal Brine Lithium Extraction Economics

Electric-Rig Direct Lithium Extraction From Geothermal Brine: The Economics of Vercana Versus Ormat Vulcan Energy Resources is pursuing an integrated model that combines geothermal drilling, direct lithium extraction, renewable electricity and industrial heat. Through its Vercana subsidiary, the company is also using electric drilling equipment designed to support the development of its Lionheart project in Germany’s Upper Rhine Valley. The approach differs from the conventional geothermal model represented by Ormat Technologies, whose core business remains geothermal power generation, equipment, project development and energy storage rather than commercial lithium recovery from geothermal brine.  The economic question is broader than whether an electric drilling rig costs less to operate than a diesel rig. The more important issue is whether electric drilling, geothermal energy and direct lithium extraction can create a more valuable integrated project than a conventional geotherm...

Western Geothermal Power Transmission Roadmap Toward 2030

Geothermal Power in the Western United States: A Transmission and Planning Roadmap to 2030 Introduction The Western United States is approaching a decisive period for geothermal power. Electricity demand is rising because of data centers, industrial electrification, population growth, electric vehicles and the replacement of retiring fossil-fuel generation. At the same time, utilities are under growing pressure to add clean resources that can operate reliably when solar and wind output declines. Geothermal power is well positioned to fill this role. Unlike weather-dependent generation, geothermal plants can provide firm electricity for long periods, support grid reliability and reduce the amount of storage required in deeply decarbonized power systems. However, the industry’s expansion will depend on more than subsurface heat and drilling technology. By 2030, transmission access, resource planning, project finance, permitting and utility procurement will determine whether geothermal be...

Unlocking Impermeable Geothermal Reservoirs: Hydraulic Stimulation, Menengai and Olkaria

Unlocking the Impermeable Reservoir: Lessons from a 30-Year Reservoir Engineer An Alphaxioms interview with Richard Joseph Holt, Principal Consultant in Reservoir Engineering at RESPEC . Context: Menengai East and Olkaria Central. Every geothermal developer knows the moment.  The rig is gone and the money is spent. The well is drilled to depth, the temperature is there, and then the well will not flow. The heat is real, but the connection between the well and the reservoir is not. Wells like this sit at the centre of one of the most important questions in geothermal development: what do you do with a tight reservoir? Walk away and drill again, or find a way to unlock what is already there? To explore the question, Alphaxioms spoke with Richard Joseph Holt, Principal Consultant in Reservoir Engineering at RESPEC . Richard brings 30 years of global experience in geothermal energy.  We framed our questions around two settings, Menengai East and Olkaria Central, and asked him how ...

Menengai Geothermal Project Delays Expose Kenya’s Broken Steam Supply Model

Menengai’s Broken Promise: How Kenya’s Geothermal Model Lost the Steam Thematic image of the Olkaria Geothermal Field  Kenya’s Menengai geothermal project was sold as a model of modern public-private partnership. The state would carry the difficult and expensive burden of geothermal exploration and drilling. Private power producers would then build, own and operate power plants. Geothermal Development Company would supply the steam; the independent power producers would convert it into electricity; Kenya Power would buy the output. On paper, the arrangement was elegant. In practice, Menengai has exposed a far more uncomfortable reality: Kenya’s public steam-supply model is not delivering the certainty it promised. Menengai Phase I was designed to produce 105 megawatts from three 35 MW plants. GDC’s own project page says the three plants were awarded to Globeleq Menengai Geothermal, Sosian Menengai Geothermal Power and OrPower Twenty Two under a build-own-operate structure. Yet the ...
