Peregrine Turbine Technologies

What Peregrine Turbine Technologies does

Peregrine Turbine Technologies (PTT) is a privately held Maine LLC founded in 2012 by David Stapp and Robert Brooks that develops supercritical carbon dioxide (sCO2) Brayton cycle turbine engines and related heat exchanger and thermal energy storage systems for power generation, energy storage, and propulsion applications. Its core technology is a closed-loop sCO2 heat engine claimed to achieve 45% thermal efficiency versus ~32% for conventional steam, with 30x greater power density, dry cooling, fuel-source agnosticism (natural gas, biomass, nuclear, concentrated solar, geothermal), and modular ISO-container transportable form factors targeting the 1MW-20MW distributed power range. Product portfolio includes the Merlin 1MW turbine, FlatPak and PowerBlock systems, a phase-change Thermal Energy Storage system using Miscibility Gap Alloy technology, and a biomass combined heat and power system, commercialized through three wholly owned subsidiaries: PTT Distributed Energy Systems, PTT Nuclear Energy Systems, and PTT Energy Storage Systems.

PTT operates a pre-revenue hardware business model with planned diversification into licensing and royalty income through its subsidiary structure, supplemented by engineering and technical services to strategic partners. Go-to-market combines direct enterprise field sales to energy, defense, and industrial buyers with channel partnerships via strategic manufacturers (TURBOCAM International) and co-development partners (EXCEED Geo Energy for geothermal, Ultra Safe Nuclear Corporation for nuclear microreactors, KMW Energy for biomass, Cianbro for solar LDES pilots). Validation is anchored by a long-term CRADA with Sandia National Laboratories (over 500 hours of sCO2 engine testing) and non-dilutive funding from the U.S. Department of Energy, Air Force Research Laboratory, Office of Naval Research, and the Maine Technology Institute, with approximately $35M deployed across 12 years of development.

The company is led by CEO/CTO David Stapp (35-year GE Aircraft Engines veteran and inventor of the Peregrine Engine) and co-founder Robert Brooks, with an advisory board spanning Sandia National Laboratories, TURBOCAM International, the US Navy, DOE, and the Tennessee Valley Authority. Strategic intent, articulated through the subsidiary structure, is to seed each market vertical and then sell majority ownership of specific market segment subsidiaries to established multinational players, converting IP into licensing and minority-stake returns while retaining core technology ownership.

Direct peers

• Echogen Power Systems: Echogen was a direct sCO2 power systems competitor developing supercritical CO2 heat-to-power systems for industrial waste heat recovery and power generation. Both companies targeted the same closed-loop sCO2 Brayton cycle architecture and competed for similar industrial and energy customers before Echogen's technology was acquired by a major OEM.
• Net Power: Net Power, developed with 8 Rivers Capital, commercializes the Allam-Fetvedt Cycle — a sCO2 Brayton power cycle that combusts natural gas with oxygen to produce electricity with near-zero emissions. Direct sCO2 power cycle peer competing in the same fuel-flexible, high-efficiency clean power generation category as Peregrine.

Emerging players

• Malta Inc. Malta develops pumped heat energy storage systems using a thermodynamic cycle similar in concept to PTT's sCO2 work, targeting long-duration grid storage. Both companies use proprietary thermodynamic cycles and turbomachinery to convert between electricity and stored thermal energy at multi-MWh scale, competing in the long-duration energy storage category.
• Energy Vault: Energy Vault provides grid-scale energy storage solutions, including thermal storage approaches, competing with PTT's LDES system for the long-duration storage market driven by renewable intermittency. While Energy Vault's primary commercial offering is gravitational storage, the company is expanding into thermal storage adjacent to PTT's miscibility gap alloy-based offering.
• Form Energy: Form Energy develops iron-air battery systems for long-duration grid storage (100+ hours), directly competing with PTT's claim of 50% lower LCOE versus lithium-ion and superior economics for multi-day renewable storage. Both target the same utility and grid operator customers seeking cost-effective long-duration storage solutions.

Broad incumbents

• GE Vernova: GE Vernova is the world's largest industrial gas turbine manufacturer and an established player in the $65B gas turbine market PTT targets. GE acquired Echogen's sCO2 technology and continues to invest in sCO2 power cycles, making it both a broad incumbent competitor and a potential strategic acquirer of PTT's subsidiary assets.
• Siemens Energy: Siemens Energy is a major industrial gas turbine OEM serving utility, industrial, and oil & gas power generation customers globally. As one of the dominant incumbents in PTT's target market, Siemens has both the resources to develop competing sCO2 systems and the customer relationships that PTT must win or partner with for scale deployment.
• Mitsubishi Power: Mitsubishi Power is a major gas turbine OEM serving the utility-scale and industrial power generation market globally. The company competes in the same distributed and centralized power generation segments PTT targets and has active programs in advanced turbine cycles, including hydrogen-ready turbines relevant to PTT's fuel-agnostic value proposition.
• Rolls-Royce (Power Systems): Rolls-Royce operates a power systems business (mtu) providing gas engine and turbine-based distributed power generation solutions. Multiple PTT senior leaders have Rolls-Royce pedigree, and Rolls-Royce's distributed power, aerospace propulsion, and nuclear interests overlap with PTT's modular sCO2 platform across multiple target verticals.
• Solar Turbines: Solar Turbines, a Caterpillar subsidiary, manufactures industrial gas turbines in the 1-22 MW range — directly overlapping PTT's targeted 1MW-20MW sweet spot for distributed energy markets. Solar Turbines is one of the incumbent gas turbine OEMs specifically named in PTT leadership's prior employer pedigree and a competitor for distributed industrial and oil & gas power customers.
