NUCLEAR DISTRIBUTED ENERGY RESOURCES
New sCO2 conversion technology enables a new generation of micro modular and very small micro modular nuclear reactors safe, clean, and cost-effective energy.
Peregrine Turbine’s Proprietary sCO2 energy conversion technology brings solutions not previously available to earlier nuclear energy systems:
- At 1.5 X the conversion efficiency of steam with MANY other “mission critical” advantages including no water cooling required, black start capability, size, and maintenance.
- At 3 X the conversion efficiency of air Brayton systems, again with MANY other “mission critical” advantages.
Peregrine’s conversion technology brings step improvement opportunity for cost, efficiency and reliability of VSMRs and MMRs.
The development and evolution of a new family of safe, highly efficient, very small nuclear reactors (VSMRs) and micro modular nuclear reactors (MMRs) has progressed substantially over the past decade and is now a very high “energy surety” priority for the US DoD as well as for industrial decarbonization in energy intense applications such as data centers and steel, cement, glass, and other industrial processes.
Peregrine’s sCO2 (super critical carbon dioxide) turbine systems are a safe and efficient means of converting nuclear energy into electrical power. The high energy density of sCO2 systems is 30X greater that equivalent steam plants, are 30% – 50% more efficient, are air cooled (no water cooling required), require no high-level licensed operators, have significantly fewer wear parts, and are specifically designed for ease of field maintainability.
The Company believes that its sCO2 system addresses the current challenge for Adjacent Plant heat to power generation involving large, complex, and inefficient steam turbines requiring significant water sources, extensive infrastructure and maintenance, licensed operator support and high costs.
The breakthrough power conversion efficiency of PTT’s heat engine provides a step increase in reactor electric power output, with a thermal to electric conversion efficiency of 30-33% for steam system compared to 45% for a Peregrine Heat Engine. This increase in conversion efficiency effectively uprates reactor output, and significantly lowers $/MWe.
This breakthrough efficiency was not by accident, but rather by design and significant investment in iterative engineering product design work. Given the necessity to provide integration of power conversion and heat transfer attributes into reactor design, we and the leading developers, feel early integration of “the cycle” into such efforts is prudent and necessary for flexible and rapid fielding. Hence, the formation of PTT NES is in anticipation of collaborative efforts for the first “balance of plant” building block upon which microreactor output will be oriented.
The genesis of the work at Sandia’s Brayton Lab for sCO2 power conversion was intended for advanced nuclear applications. PTT’s sCO2 technologies have both benefited from and advanced that endeavor.
