Vision
Superhot geothermal at gigawatt scale
Power that is clean and available every hour is the scarce commodity in the next energy system. Superhot geothermal can deliver it at the density and scale that system requires.
Global potential
The resource is global
Preliminary modelling by Clean Air Task Force, developed in collaboration with the University of Twente, suggests that the theoretical superhot geothermal resource is vast. Their estimate indicates that accessing just 1% of global superhot rock potential could represent around 63 TW of power.
The resource is not the constraint.
The challenge is building the wells, systems and commercial model capable of accessing it repeatedly — from field validation through conventional project finance to deployment across markets.
That is what Eldar is building.
Market
Firm supply is becoming the constraint
Digital infrastructure
AI and cloud infrastructure require large volumes of dependable 24/7 electricity.
Electricity grids
Variable generation and retiring thermal assets increase the need for clean, firm capacity.
Industry
Heavy industry, high-temperature processes, hydrogen and synthetic fuels need continuous energy and high utilisation.
Superhot geothermal can serve all three: clean, firm power with exceptional energy density.
Why superhot
Power density changes the economics
More energy from each well changes how many wells a project requires, how quickly capacity can be added and how much land and capital are needed for every megawatt.
More power per well
IDDP-1 demonstrated more than 30 MW of potential. Newer modelling places the upper engineering potential at around 50 MW in favourable reservoir conditions.
Power independent of weather
Dispatchable, high-capacity-factor generation, unaffected by season or time of day.
Beyond volcanic fields
Eldar will begin where natural permeability provides the fastest route to commercial deployment, then extend into superhot enhanced geothermal systems.
Development programme
The path to commercial scale
The early stages do more than validate individual assets. Each one turns field results into what the next project is built from.
Engineer the commercial design basis
Develop the design basis, supplier strategy and drill-ready package for a commercial superhot well.
Prove the well
Drill, complete and operate the well: casing, cement, materials, wellhead, surface handling and controlled flow.
First commercial asset
Deliver a contracted commercial power asset in Iceland with a resource holder, offtake and project capital.
Utility scale
Add wells and repeat power systems at utility scale, using enhanced geothermal systems where needed.
Deploy the fleet
Deploy standardised wells and power systems in Iceland and international markets as operating knowledge, supply-chain capacity and economics compound.
Why Iceland first
The fastest route to commercial deployment
Iceland is where superhot geothermal has already been drilled, produced and studied. It combines world-class resources, deep geothermal capability and the relationships required to move quickly from technical proof to commercial deployment.
What is learned in Iceland is designed to travel. Geology and fluid chemistry will vary, but the core well architecture, qualification methods, operating envelope and development process should not begin from a blank sheet in every field.
Ambition
From Iceland to gigawatts worldwide
Eldar integrates technology development, project formation and field execution so superhot power can move from individual projects to a global industry.
Hundreds of wells. Gigawatts of clean, firm power.
