Wiscasset, ME. May 3, 2023 – Peregrine Turbine Technologies (PTT) and Our Katahdin, a 501(c)(3) nonprofit organization, have announced a Memorandum of Understanding outlining their plan to pilot a Peregrine biomass combined heat and power (CHP) generation system. The sCO2-enabled system will provide renewable electric power and district heating to Our Katahdin’s planned “Innovation Hub” their One North Industrial campus. The CHP system will demonstrate the Peregrine sCO2 system’s commercial capabilities and performance.  The CHP project has received support from the Department of Energy through a Fiscal Year 2023 Congressionally Directed Spending Request of $2,500,000 sponsored by Senator Collins and Senator King.

“We are eager to field our groundbreaking, proprietary system capable of providing sustainable power and heat for various applications, including district heating, commercial, and industrial applications. This system has significant performance advancements over current best technology systems,” stated David Stapp, COE/CTO and Co-Founder of PTT. “We are particularly grateful for the support of the Our Katahdin and the opportunity to demonstrate our advanced sCO2 energy conversion technologies in such an exciting and innovative commercial environment.”

PEREGRINE’S sCO2 Cycles and Technologies Are a Strong Fit with Biomass CHP Applications 

Peregrine Turbine Technologies Biomass Power Generation System projects 1.7 X efficiency improvement over “best available” biomass conversion technology and 2.7X improvement over currently used closed thermodynamic systems. The innovative sustainable biomass system integrates the best current direct combustion system technology with Peregrine’s proprietary sCO2 power block and heat exchanger elements.

The innovative CHP system has a small footprint based on the company’s unique modular designs that enable application-specific system configuration. In addition to locally sourced biomass, the system has a broad fuel conversion capability that covers 70%+ of available fuel types in its targeted global markets, including refuse-derived fuels (RDF) and some municipal bio-solids. It is designed for operational flexibility and can work with 60% moisture content fuel input.

Developing efficient, cost-effective combined heat and power systems capable of operating on local, sustainable fuel sources, with minimum transmission and distribution infrastructure at or near the point of use, will lessen the increasing burden on existing grid systems, bringing clean energy to remote locations.

Our Katahdin’s Innovation Hub on the One North industrial site was once home to multiple Great Northern Paper buildings supporting paper manufacturing. The mill’s closure in 2008 and the demolition of the site’s boiler complex eliminated heat to these buildings. The pilot CHP facility will provide renewable bio-mass power and a district heat source to buildings in the planned Innovation Hub.

“We believe that PTT’s technologies will be transformational in bringing a flexible, clean energy solution to our location, powered by local and sustainable biomass fuels. We are pleased to have the opportunity to showcase this technology at the Innovation Hub on the One North campus,” said Sean DeWitt, President of Our Katahdin. “We look forward to partnering with Peregrine on this project and other commercial relationships.  We are also grateful for the continued support from our congressional delegation as our redevelopment efforts progress.”
