Heatric has been chosen to supply the vitally-important recuperative heat exchangers for the first-of-a-kind supercritical CO2 (sCO2) power plant being built by NET Power, CB&I, Exelon Generation, Toshiba and 8 Rivers Capital in Texas, USA.
Under this deal Heatric will deliver a total of four printed circuit heat exchangers (PCHEs) by the end of April 2016. The 50MWt demonstration plant is expected to begin commissioning towards the end of 2016.
Net Power’s novel ‘Allam Cycle’ power system is the first natural gas-fired power generation system able to produce low cost energy with zero air emissions. The plant’s only major by-products are liquid water and a pipeline-quality, high-pressure stream of carbon dioxide ready for sequestration or industrial use.
“This technology is a potential game-changer when it comes to the rapid reduction of carbon emissions from fossil fuel power generation. We are very pleased to be part of such an exciting and important project with such global potential,” says Heatric general manager Adrian Tattersall.
Heatric heat exchangers are already a well-established technology in offshore gas production, with some 2700 units in operation all over the world. Their unique solid-state, diffusion-bonded design creates a much stronger, more efficient and compact exchanger, almost impervious to the harsh offshore operating environment.
This new contract is an important win for Heatric’s ‘emerging technologies’ operation. Heatric engineers work closely with customer organisations to develop new and exciting applications in many fields, including ‘green’ energy generation and storage. Net Power employs sCO2 technology to create cleaner, more efficient core generating capacity. The ability of Heatric PCHEs to capture and recycle much more of a given energy flow, whether hot or cold, makes a critical contribution to the economic viability of the process.
“Heatric printed circuit heat exchangers have become a key enabling technology in modern sCO2 power cycles like that developed by Net Power,” says Robert Broad, Heatric’s Business Development Manager. “To achieve the high efficiencies needed to make this sCO2 cycle viable NET Power relies on ‘recuperation’ - recapturing as much heat as possible as it exits the turbine - to reduce the fuel required to generate a given amount of electricity. The recuperative heat exchanger must deliver very high effectiveness while also coping with the high temperatures and pressures. The printed-circuit, diffusion-bonded design of Heatric PCHEs makes for a tough, compact and very efficient unit ideally suited to this role. As a company we have 25 years’ experience of working closely with customers to tailor our technology to the needs of new and sophisticated applications in challenging environments, making Heatric a uniquely valuable development partner for such organisations.”
