Tekcapital launches geothermal data center company for AI workloads
UK intellectual property investment firm Tekcapital has formed Vesari, a portfolio company designed to build and operate geothermal-powered data centers built specifically for AI computing.
The company will co-locate AI compute directly with geothermal power generation in a fully integrated setup that operates independently of the traditional electrical grid. Vesari will use low Earth orbit satellite connectivity instead of conventional fiber networks.
How the model works
Vesari's prototype integrates power generation, cooling, compute orchestration, and revenue management into a single closed-loop system. The company holds eleven patent applications related to the design.
The model creates what the company describes as a reinforcing feedback loop across power, cooling, compute, pricing, and power utilization. The stated aim is to improve energy efficiency, compute throughput, and revenue quality.
Louis Castro, director of Tekcapital, said the venture addresses a fundamental constraint on AI infrastructure: power supply, not semiconductor availability. "By co-locating AI compute directly with geothermal power generation, behind the meter, and connecting it via LEO satellites, we believe that if successful, Vesari can enable more efficient, 24/7 carbon-free compute capacity," Castro said.
Ownership and funding
Tekcapital Europe will hold a 51 percent stake in Vesari, with Tekcapital executive chairman Dr. Gross holding the remaining 49 percent. The company expects to secure most future funding independently of Tekcapital.
Broader industry trend
Vesari's formation reflects growing interest in geothermal power across the data center sector. Google, Meta, Microsoft, and Amazon have already signed agreements to purchase power from geothermal sources.
