The Board of Directors, Regi U.S., Inc. and its wholly owned subsidiary, RadMax Technologies, Inc., are pleased to announce the delivery of an expander-generator to the Pacific Northwest National Laboratory (PNNL) in Richland, Washington, USA.
The RadMax device was commissioned by PNNL to support the construction and demonstration of their patent pending, Harmonic Adsorption Recuperative Power (HARP) energy generation system. The HARP system utilizes PNNL’s innovative, non-condensing thermodynamic cycle technology to generate electricity from low temperature heat sources such as geothermal, solar and waste process heat previously thought too uneconomical for this purpose. With no need for fluid condensation, less heat is rejected to the environment allowing the HARP system to produce power even under high ambient temperature conditions where competitive systems shutdown.
The self-contained RadMax expander will be used to expand the high-pressure refrigerant created by the HARP system to produce up to 1 kW of electrical power.
The HARP research project is funded by the Department of Energy’s Geothermal Technologies Office and is one of several projects RadMax is collaborating on and jointly pursuing with PNNL.
