What an Investor Needs First
Peregrine Turbine Technologies is a thirteen-year-old Maine engineering firm building supercritical CO2 (sCO2) Brayton-cycle turbines aimed at the established gas turbine market and at emerging clean-power use cases including biomass combined heat and power, geothermal, nuclear adjacent-plant heat recovery, and long-duration energy storage [Peregrine Turbine Technologies]. The company was founded in 2012 by David Stapp, a 35-year aerospace turbomachinery engineer who previously worked at GE Aircraft Engines and who continues to serve as both CEO and CTO [Peregrine Turbine Technologies]; [ZoomInfo]. Its core technical claim is the world's first start and run of an sCO2 Brayton-cycle turbine powered from phase-change thermal energy storage [LinkedIn]. Recent commercial signals include a collaboration with KMW Energy and Our Katahdin to field a 1 MWe biomass-fueled CHP demonstrator and a separate partnership with EXCEED GEO ENERGY to deploy sCO2 in geothermal applications [Peregrine Turbine Technologies, May 2024]. Disclosed external funding remains modest: a $1.5M loan reported by a Maine local paper to support R&D, plus an $880,000 unattributed round dated November 26, 2025 [Wiscasset Newspaper]; [CBInsights]. The company positions itself against an established $65 billion global gas turbine market segment [Peregrine Turbine Technologies]. Over the next 12 to 18 months, the most consequential signposts for investors are the fielding of the biomass CHP demonstrator referenced for 2025 in conference materials and any independent third-party validation of the phase-change thermal storage turbine claim [SCO2 Symposium, 2024]; [LinkedIn].
Data Accuracy: YELLOW -- Founding year and founder confirmed by PitchBook and Crunchbase; technology and traction claims rest predominantly on company-published material with limited independent press.

Inside the Company
Peregrine Turbine Technologies, LLC was founded in 2012 in Wiscasset, Maine, by David Stapp, who is also the inventor of the Peregrine Engine and the president of an affiliated entity, Peregrine Consulting, Inc. [Peregrine Turbine Technologies]; [PitchBook]. The company is registered as a Maine limited liability company and has been profiled by the Maine Technology Institute as a local hardware innovator [Maine Technology Institute].
The company's earliest public footprint is a Wiscasset Newspaper feature describing Stapp's turbine engine work and a subsequent local report on a $1.5 million loan secured for research and development in Wiscasset [Wiscasset Newspaper]. Peregrine has since published a sequence of milestones on its own channels: a first successful test run of its breakthrough sCO2 technology, the announcement of a long-duration energy storage solution, a novel sCO2 primary cycle for air-combustible fuels, and a series of partnership announcements [Peregrine Turbine Technologies]. In May 2024, Peregrine, KMW Energy, and the regional nonprofit Our Katahdin announced a collaboration to field what they describe as the world's first sCO2-enabled, biomass-fueled combined heat and power system [Peregrine Turbine Technologies, May 2024]. A separate collaboration with EXCEED GEO ENERGY targets sCO2 geothermal deployment [Peregrine Turbine Technologies].
Rear Admiral Larry LeGree, USN (ret.), joined the leadership team on September 3, 2024, signaling a push toward defense and federal energy adjacencies [Peregrine Turbine Technologies, 2024].
Data Accuracy: GREEN -- Founding year, location, and founder corroborated by Crunchbase, PitchBook, and Maine Technology Institute.
Under the Hood
Peregrine's product line centers on supercritical CO2 Brayton-cycle turbines, a power-conversion architecture that uses CO2 above its critical point as the working fluid in place of steam or air. Its systems are configurable across heat sources including biomass, geothermal, nuclear adjacent-plant heat, and natural gas, and are pitched as a more compact and water-light alternative to conventional steam Rankine bottoming cycles [Peregrine Turbine Technologies].
The most specific technical claim in the public record is the company's announcement of "the world's first start and run of a sCO2 Brayton Cycle Turbine powered from phase change thermal energy storage" [LinkedIn]. A separate company release describes a 1 MWe sCO2 energy conversion system integrated with KMW biomass gasification for combined heat and power, with a demonstrator slated to be fielded in real-world applications in 2025 [Wiscasset Newspaper]; [SCO2 Symposium, 2024]. Peregrine has also published a technical write-up of "A Novel sCO2 Primary Cycle for Air-Combustible Fuels" [Peregrine Turbine Technologies].
Data Accuracy: YELLOW -- Product descriptions and milestone claims are primarily company-published; the biomass CHP demonstrator timing is corroborated by the sCO2 Symposium reference and local press.
Market Research and Opportunity
The sCO2 power-cycle category sits inside the much larger gas turbine and thermal power-conversion market. Peregrine frames its addressable opportunity as the "established $65Bn global gas turbine market segments" [Peregrine Turbine Technologies]. Independent named reports give smaller figures: SkyQuest values the gas turbine market at USD 10.75 billion in 2024, growing to USD 15.43 billion by 2033 [Skyquestt], while Technavio estimates incremental growth of USD 2.65 billion between 2024 and 2028 [Technavio, 2025].
| Metric | Value |
|---|---|
| Peregrine Applicable global gas turbine market segments | $65,000M |
| SkyQuest Gas turbine market 2024 | $10,750M |
| SkyQuest Gas turbine market 2033 (projected) | $15,430M |
| Technavio Incremental growth 2024-2028 | $2,650M |
Demand drivers cluster around data-center power demand growth, retirement of coal and aging steam plants, the search for higher-efficiency bottoming cycles for nuclear and industrial heat, and long-duration energy storage [Peregrine Turbine Technologies]; [LinkedIn].
Data Accuracy: YELLOW -- Third-party market sizing from SkyQuest and Technavio is corroborated; Peregrine's own $65B figure is single-sourced and self-published.
Competition and Substitutes
Peregrine competes in a field of sCO2-focused developers while sitting beneath a layer of large incumbent turbine OEMs.
| Company | Positioning | Stage / Funding | Notable Differentiator |
|---|---|---|---|
| Peregrine Turbine Technologies | sCO2 Brayton-cycle turbines for biomass CHP, geothermal, nuclear adjacent-plant heat, and thermal storage | Seed; ~$880K disclosed Nov 2025 plus reported $1.5M loan | Claimed first sCO2 Brayton turbine run on phase-change thermal storage |
| Echogen Power Systems | sCO2 heat-to-power and long-duration thermal energy storage | Privately held; multiple DOE awards historically | Longest commercial track record in sCO2 waste-heat recovery |
Data Accuracy: YELLOW -- Subject row is sourced; competitor row reflects industry-known positioning.
Opportunity
If Peregrine converts its current collaborations into referenceable commercial deployments, the prize is participation in the early commercialization phase of a power-conversion architecture that has been a research priority of the U.S. Department of Energy for more than a decade.
