Technology Description:

Brayton Energy is developing an efficient and low-cost distributed residential-scale combined heat and power system. This project seeks to advance and combine several complementary technologies—including metallic screw compressors, high temperature ceramic screw expanders, and a high-effectiveness recuperator. This combination will result in an integrated system with performance surpassing existing state-of-the-art systems. Brayton Energy’s proposed technology would continuously deliver 2 kW of electrical power and enable efficient and economical distributed power systems that would radically transform how we heat and cool our homes.

Potential Impact:

Brayton Energy inverts the paradigm of large centralized power plants by enabling efficient, economical, and attractive distributed power systems.

Security:

The unit’s residential scale decentralizes the nation’s critical power infrastructure, reducing its vulnerability to attack or disruption.

Environment:

Widespread adoption of high-efficiency residential CHP systems could decrease overall primary energy consumption and therefore reduce CO2 emissions from a household by up to 40%.

Economy:

The system is efficient, durable, and economical, achieving payback in under four years for much of the U.S. This will boost its marketability and adoption by customers.
