Hot Dry Rock

We develop Renewable Low Carbon Energy Generation projects in Europe by deploying Hot Dry Rock (“HDR”) technologies.

We license those technologies best suited for each project and develop our own intellectual property associated with geothermal heat and power generation projects.

HDR technologies can benefit a wide range of heat and power and generation systems.

How do the different Hot Dry Rock technologies harvest heat and power from the Earth?

  • Open Loop EGS

    Open Loop

    Stimulation creates an artificial reservoir

    Multiple boreholes: higher CAPEX/MW

    - Reservoir must connect across multiple boreholes
    - Requires continuous injection of large volumes of water at high pressure (10’000 to 15’000 PSI)
    - Fluid must disperse evenly to avoid short circuiting into a single flow channel
    - Huge parasitic loads from friction pressures

  • Closed Loop

    Closed Loop

    Boreholes form a “radiator” shape underground

    Single & multiple boreholes: requires tens of km of drilling length for sufficient surface area for heat transfer
    - New technology is needed for complex directional drilling and borehole completions
    - No connectivity with surrounding rock, conduction heating only
    - Lower power output per borehole than open loop systems

Co-location

We can offer co-location of renewables power generation to convert existing Ground PV, Onshore Wind and Thermal into integrated and scalable baseload renewable energy generation plants.

Sustainable & Secure

We offer heat and power production technologies that are more sustainable and raw material-secure than any other storage or renewable power generation system.

Our energy production does not rely on critical materials necessary for other renewable energy generation systems.
