Project Description

Brayton Energy’s goal for this project is to advance the state of development of heat exchanger technology for high-temperature (up to 850 degrees Celsius), high-pressure (up to 25 Megapascal) operating conditions within advanced power generation applications, such as supercritical carbon dioxide (SCO2) power cycles. The work will be based upon Brayton's plate-matrix heat exchanger technology, currently under development. The scope for this project includes manufacturing development, heat exchanger characterization testing, and cost modeling. The flattened-panel heat exchanger cell was conceived and prototyped as part of DOE contract DE-EE0005799.

Project Benefits

The Brayton Energy project will focus on manufacturing advancements in order to substantially lower the capital cost of heat exchangers, with its primary objective a projected high-volume production cost of $40/kilowatt thermal or less for the high-temperature and high-pressure SCO2 heat exchangers. High-efficiency SCO2 power cycles using these plate-matrix heat exchangers operate with reduced specific fuel consumption compared to state-of-the-art systems and require less volume of material to produce. Lower cost, smaller size, broader range of material options, minimal material wastage, and quicker and simpler processing all produce a final design that costs less than a printed-circuit heat exchanger sized for comparable duty.
