London Geothermal Ltd

Next-Gen Geothermal,
Anywhere on Earth.

Urban decarbonization requires scalable, space-efficient energy solutions. London Geothermal Ltd introduces GeothermalHub—a modular, container-sized geothermal system powered by next-generation ultra-efficient turbines. From Central London to global capital cities, our technology delivers 24/7 baseload electricity, district heating, and high-efficiency cooling tailored for critical infrastructure like data centers—all within a minimal physical footprint.

What we do

Geothermal work spans a wide range of depths and technologies. We cover the full range, from shallow heat pumps to deep binary power.

100–250 M

Ground source heat pumps

Closed and open-loop systems sized and designed for individual buildings, campuses, and neighbourhoods.

300–1,000 M

ATES & BTES storage

Seasonal underground thermal storage that banks summer heat and releases it again in winter.

SURFACE

District heat networks

Feasibility studies and network design that connect a geothermal heat source to a whole town or district.

1,000–5,000 M

Deep geothermal

Drilling programmes and reservoir engineering for direct heat and power projects at depth.

ANY DEPTH

Technical due diligence

Independent review of resource, well, and plant data before capital is committed to a project.

BINARY CYCLE

ORC power generation

Organic Rankine Cycle plant selection and integration for lower-temperature resources.

Feasibility & Sector Solutions

Rapid feasibility assessments and engineered geothermal solutions for high-energy demand industries, sustainable transition, and smart agriculture.

HIGH-DENSITY COOLING & POWER

Datacenter Solutions

24/7 Base-Load / Zero-Carbon Cooling

Rapid assessment of shallow and deep geothermal cooling systems for modern data centers. Utilizing closed-loop heat exchangers to absorb massive thermal loads, drastically reducing Power Usage Effectiveness (PUE) and water consumption.
