Enhanced geothermal systems

Clean, reliable and affordable energy from heat beneath the surface.

Eonic is advancing enhanced geothermal systems in Alberta by combining deep drilling and engineered reservoirs to produce electricity and heat.

What makes enhanced geothermal different

Traditional geothermal depends on rare natural conditions where heat, water, and permeability already exist together. Enhanced geothermal systems take a different approach.

Fractures are created in deep, hot, impermeable rock to allow injected water to flow where it otherwise wouldn’t and brings usable heat back to the surface.

This expands where geothermal energy can be developed and creates a pathway for reliable energy in more regions.

How it works

Enhanced geothermal systems use drilling and hydraulic fracturing to move water through hot, dry rock deep below the surface. The system is designed to capture underground heat and bring it back to the surface, where it can be used to generate electricity or provide direct heat.

  • Deep wells are drilled several kilometres below the surface into rock formations with usable heat. The goal is to find the right combination of depth, temperature, and geology to support long-term energy production.

  • The reservoir is engineered so water can move through the hot rock and absorb heat. Well design, completions, and reservoir creation techniques help create and maintain the pathways needed for circulation.

  • Water is injected into the system and moves through the engineered reservoir. As it travels through the rock, it absorbs heat from the surrounding formation.

  • The heated water returns through a production well. At the surface, that heat can be transferred into a power generation system used organic rankine cycle technology or used directly.

  • Clean electricity generated can be sold via the electricity grid or directly to behind-the-fence loads. Alternatively, heat can be sold directly for district heating, food production or industrial applications.

Why drilling expertise matters

Enhanced geothermal systems are not only about geology. They depend on execution.

Deep drilling, well construction, reservoir design, completions, and subsurface monitoring all play a role in whether a system can perform reliably.

That is why Alberta matters. The province already has the workforce, equipment, supply chain, and technical knowledge needed to support complex underground energy development.

Pathway to scale

The opportunity is repeatable.

As enhanced geothermal systems are developed, costs can improve through iterative improvements in drilling and completions, optimized system designs, and standardized supply chains.

That gives enhanced geothermal a path to become a scalable source of clean, reliable and affordable electricity and heat.
