Developing renewable, baseload power projects in Europe

We generate Energy From Rocks™

TerraThermo™ develops Renewable, Baseload Low Carbon Power Generation projects by deploying reservoir-independent Hot Dry Rock (“HDR”) technologies.

We deploy those technologies best suited for each GeoPower project and develop our own intellectual property associated with HDR GeoPower generation projects.

The Earth’s crust is only 1% of the planet’s radius and volume, so Hot Dry Rocks are remarkably close to the surface in many parts of Europe. Even with current mechanical drilling technologies, this deep heat resource is readily accessible at depths of less than 5km in sedimentary basins.

Hot Dry Rocks are present in the subsurface because of elevated heat flows from beneath the Earth’s crust.

Mapping of this heat flow distribution allows determination of temperature anomalies and exploration for HDR geothermal resources.

Integrated GeoPower Systems™

For each GeoPower project we undertake an Integrated GeoPower Systems™ analysis that allows us to deliver the optimum combination of surface production facilities and subsurface heat extraction technologies to maximise power output and life-of-field.

Our Integrated GeoPower Systems™ analysis workflow includes:

  • Basin and Play Fairway analysis

  • Geological and Geophysical interpretation and analysis

  • Integration with Airborne Full Tensor Gravimetric surveys

  • Static 3D structural, reservoir and heat flow models

  • Heat Resource and Reserve estimates

  • Assessment of induced seismicity risks

  • Thermal modelling and analysis

  • Single, doublet or triplet borehole modelling

  • Borehole design and drilling risks assessment

  • ORC plant components & power output modelling

  • Grid connections, environmental restrictions and planning requirements.

For Projekt THERMO in Lower Saxony, Germany, we are deploying proven technologies mostly transitioned from the Oil & Gas industry to develop this first-of-a-kind 12MWe baseload power generation project.

Scalable from micro-grids to dedicated industrial baseload power supply

Unlike hydrothermal geothermal project developers, we do not require subsurface reservoirs so our GeoPower projects are largely independent of geological constraints.

Our GeoPower plants are scalable to provide local green power supplies in modular power stations from an installed capacity of 1MWe to large scale industrial baseload power supplies in 50 MWe modules and more.

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

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

Unlike conventional hydrothermal technologies, HDR geothermal technologies do not require a reservoir with porosity and permeability that is sufficient to flow geothermal brines. Instead, they rely on upon either:

Conduction of heat energy from the surrounding formation into a working fluid in the borehole through a closed-loop system; or…

Illustration of HDR technologies that rely upon heat energy convection from brine flowing through fractures in surrounding rock formations between two boreholes.

Extraction of heat energy by brines flowing through natural fractures or fractures created by stimulation between two boreholes; or…

Sustainable & Secure

We provide green power production that is more sustainable and raw material-secure than any other renewable power generation system.

We do not rely on critical materials necessary for other renewable energy generation systems.
