Technology Description:

Creare, in partnership with IMBY Energy, is developing a mass-manufacturable, recuperated, closed-loop Brayton-cycle microturbine that will provide 5 kW of electrical power for residential and commercial buildings. The waste heat from the device can be harvested for heating. Technical innovations in the system that are anticipated to enable high efficiency at an attractive cost include a diffusion bonded foil recuperator, a turbomachine with specialized hydrodynamic gas bearings, a binary working fluid mixture and flameless combustion.

Potential Impact:

If successful, Creare’s system would reduce residential primary energy consumption, improve electric grid operation, and stimulate domestic manufacturing.

Security:

Innovations developed in this project could help households and businesses become more energy self-reliant and less susceptible to energy-related outages through distributed, local generation of electrical power and heat.

Environment:

Increased power generation efficiency and waste-heat utilization will reduce primary energy consumption and related emissions.

Economy:

Creare’s closed-loop Brayton-cycle microturbine and the combined cooling, heat, and power systems that use them will be manufactured in the Northeast USA, stimulating domestic manufacturing and promoting U.S.-based advanced energy technologies.
