Supercritical Carbon Dioxide (sCO2) Brayton Cycle energy conversion systems have the potential to provide the world with cleaner and more affordable power.
Today, coal, nuclear, gas, and concentrating solar energy plants use the Rankine Cycle (steam and water) to convert heat energy to electricity. The sCO2 Brayton cycle has the potential to reach thermal efficiencies much greater than the Rankine cycle. Capital costs of the turbomachinery can also be lower because the high density of the sCO2 requires smaller turbomachinery.
Primary Cycle Efficiency (without cogeneration):
Interest in this technology is high, and governments, including the U.S. Department of Energy (DOE), are funding research to support the commercialization of this promising new technology. Concepts NREC has been awarded two Small Business Innovation Research grants (SBIRs) to help solve the many technical challenges involved in bringing sCO2 technology to the market.
The areas that Concepts NREC is working on to help solve some of the technical challenges of sCO2 power generation are: Improving Efficiency and Reducing Costs for the Supercritical C02 Design Process, optimizing the choices for the recuperator effectiveness vs. turbomachinery efficiencies that can be economically achieved and Magnetic Bearings for Supercritical CO2 Service.
Concepts NREC, as the experts, works with clients to design and analyze the types of turbomachinery required for an efficient sCO2 system. Are you ready to start the conversation about your sCO2 needs? Contact us

Concepts NREC designs, manufactures and tests turbochargers and turbocharger components for diesel and gasoline engines as well as compressor and turbine stages for gas turbine engines. We can also provide auxiliary system components for engines including fuel, oil and water pumps.
Concepts NREC has extensive experience in the field of waste heat recovery, including providing ORC turbines for exhaust heat recovery from diesel and gas turbine engines.
We cover the full range of transportation industries, including passenger cars, trucks, F1 racing, off-road vehicles, marine craft of all sizes, and aircraft piston, turbojet and turbofan engines.
In addition to contract manufacturing complete turbomachinery products for customers, Concepts NREC manufactures and sells specialized turbomachinery products that serve well-defined niche applications.
These products are jointly developed with customers who first establish a market need for a new or improved technology. Concepts NREC then supplies the development expertise to turn their specification into a successful product. However, rather than just providing services for a fee, development costs are shared, enabling Concepts NREC to establish additional applications and markets for the product and generate noncompetitive sales. The results allow development costs to be amortized over larger production quantities, and both companies further benefit by producing a better product at a lower cost.
APS is Concepts NREC’s software maintenance and support program that elevates us from just a software provider to a valued partner.
An APS subscription is included with all annual licenses and is a highly-recommended option for perpetual software licenses. Every software customer is supported for one month following purchase for any installation questions that may arise. Learn more on the Agile Products Support Membership Benefits Datasheet.

The parallel operation of two compressors used in a typical Recompression sCO2 cycle will require the mastery of the techniques described in this textbook to avoid surge and stall in compressors as well as to control the splitting of the flow between the two compressors.
