Our Projects
Geothermal Fields
Mantlepower Geothermal is developing and prospecting geothermal fields. The geothermal fields are all high enthalpy energy rich fields of either DeepGeo or MagmaGeo type. We are also constantly looking for acquisition opportunities: specifically operational plants, or developed geothermal wells.
Acquisition
Mantlepower is interested in acquiring plants that we can transform from low- or mid-enthalpy fields to high enthalpy fieds. We are also interested in acquiring discontinued wells in select markets that we can redevelop into high-enthalpy wells.
International
We are currently planning to build 126.14 TWh of geothermal plants in the following markets; Germany, Greece, Iceland, Italy, New Zealand, Sweden, Tanzania & United Kingdom.
What We Do
Prospecting
Mantlepower’s analysts have prospected more than 100 sustainable geothermal fields and have selected the 15 best targets, based on geophysical data, local electricity market, democratic stability, and investment climate.
Building Plants
We develop and build large-scale state-of-the-art high enthalpy geothermal plants for our own geothermal fields. These are plant-wide closed loop installations, ensuring the net-zero release of CO2. All plants are built to produce load-balancing electricity, process heating & hydrogen, optimising efficiency.
Supplying Energy
Our stated goal is to build sufficient geothermal plant capacity worldwide, in electricity, process heating and hydrogen, to reduce the current global output of CO2 by 10%. Big problems require big solutions.
