On February 25 from 12:00–1:00 PM, RePower Wiscasset will host a geothermal information session at the Maine State House Visitor Center (lunch provided). The session is designed for state legislators and policymakers and will feature a presentation by David Stapp, CEO of Peregrine Turbine Technologies.
This informational briefing will introduce advancements in closed-loop supercritical CO₂ (sCO₂) geothermal technology and explore how next-generation geothermal systems could contribute to Maine’s long-term energy strategy.
Closed-loop geothermal systems circulate fluid through a sealed network of deep subsurface pipes. The fluid absorbs heat from hot rock formations and carries it to the surface, where it powers turbines or provides direct heating. Because the system is fully closed-loop, it does not require naturally occurring hydrothermal reservoirs and avoids the environmental concerns associated with fluid reinjection.
The sCO₂ system being presented offers several distinguishing features:
No fracking
No water usage
A proprietary, emissions-free energy process that includes CO₂ sequestration
Hyper-scalability for distributed and utility-scale applications
Claimed energy yields exceeding current conventional geothermal technologies
Recent advances in directional drilling now make it possible to reach 4–5 mile depths beneath Maine, far beyond traditional 1,000-foot wells. Combined with advanced turbine design, these developments represent what many describe as a significant step forward in geothermal energy production.
Our flyer (see PDF attached below) outlines comparative characteristics between sCO₂ geothermal systems and other mainstream power sources, including fossil fuels, solar, wind, and water-based geothermal. Key attributes highlighted include:
Very high reliability
30+ year projected lifespan
No water use
No fracking requirement
Carbon-negative emissions profile
Smaller land footprint
Lower parasitic energy losses
Greater geographic flexibility
Competitive lifetime cost structure
The presentation will also address emerging market demand for distributed geothermal “power islands,” particularly for data centers and grid applications in the United States and Europe.
As Maine evaluates pathways to strengthen grid reliability, support economic development, and reduce long-term emissions, emerging geothermal technologies are increasingly part of the conversation. This session provides legislators with an opportunity to hear directly from industry leadership and better understand both the technical foundations and the economic implications of this evolving field.
RePower Wiscasset is pleased to help facilitate informed dialogue around innovative energy solutions that may hold promise for communities across Maine.
