Next-Gen Geothermal Funding 2026: VCs, Banks, Government Capital

By Robert Buluma Alphaxioms
Who Is Really Funding Next-Gen Geothermal in 2026? Next-generation geothermal has moved beyond laboratory research into a capital-intensive commercialization phase. In 2026, the most important financing is no longer coming from one investor category: venture capital funds are financing drilling, subsurface modelling and hardware; strategic energy companies are providing equipment, project access and market credibility; banks are beginning to lend against contracted projects; and governments are absorbing exploration and first-of-a-kind technology risk. The strongest financing activity is concentrated in the United States and Canada, but Europe is becoming increasingly important through Germany-based deployment, European Union grants, UK innovation support, and strategic participation from European energy companies. The central investment question is changing from “Can this technology work?” to “Can the developer deliver repeatable, financeable projects at commercial cost?” The 2026 fun...

Unlocking Impermeable Geothermal Reservoirs: Hydraulic Stimulation, Menengai and Olkaria

By Robert Buluma Alphaxioms
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 ...
