Unlocking the Potential of Geothermal Power

Renewable, Baseload Energy from Geothermal Heat

Geothermal energy is the only renewable energy capable of providing 24/7 base load capacity. The U.S. Department of Energy expects geothermal energy to increase 16-fold to GWe by 2050, supplying 20% of U.S. renewable energy generation.
‍
To reach this goal, we need to develop enhanced geothermal systems (EGS), man-made reservoirs created where temperatures are high but provides insufficient permeability for power generation. Low permeability resources are available over a larger geographic area and have~100x more resource potential than conventional hydrothermal resources.

The problem

Limited Scalability of Traditional Geothermal Resources

There are only a few places in the world known for easily accessible geothermal energy, such as California and Iceland.
‍
Unfortunately, most of the easily accessible geothermal resources have been developed. The remaining 95% of geothermal resources exist within low-permeability reservoirs.

The U.S. Department of Energy recently highlighted the need for novel reservoir stimulation techniques to unlock GWe of renewable power potential by reducing the cost of next-generation geothermal systems by up to 90%.

The solution

The Future of Geothermal Power Generation

Effective reservoir stimulation will maximize subsurface permeability, enabling the development of 100+ GW of geothermal energy.

Electrical Reservoir Stimulation enables greater directional control of the created fracture network, stimulating target areas and mitigating the issues caused by short-circuit fractures. This maximizes the stimulated reservoir volume and ensures maximum power generation from the resource.

Environmental Impact

Utilizing electricity to stimulate saves millions of gallons of water per well

Energy from renewable sources can power electrical stimulation

Geothermal heating and cooling produces 85% less CO₂ emissions

Installed Power Generation Capacity by Geothermal Resource Type

EGS achieve notable deployment rates with technology innovation as a result of significant reductions in installation capital cost. EGS is predicted to supply 8.5% of total electricity generated by 2050 (vs. 0.4% today).

Figure Note: The technology improvement (TI) scenario incorporates the resulting cost reductions that enable additional deployment. At the end of the analyzed period (2050), total geothermal deployment in the TI scenario is more than 60 GWe, with the majority of growth supplied by deep-EGS resource development after 2030.

Direct Use of Geothermal Heat Can Apply to a Wide Range of Industrial Applications

Figure Note: At geothermal temperatures not suitable for power production (less than 150°C), geothermal heat is still a valuable energy source.
