Supercritical CO2 Turbo-Alternator-Compressor (TAC)

Technology Marketing SummaryThe TAC unit works with supercritical fluids and high pressure gases that are above critical pressure to create energy. By harnessing the heat from the reactor, the TAC creates efficient, cost-effective energy with significantly less space consumption.DescriptionThe compressor unit contains a turbine, compressor, alternator/generator, bearings, and seals. Each of these components have been examined for how to increase efficiency, accommodate high pressures, fluid densities, reduce windage loss, bearing cooling, etc.Benefits

• Revolutionary performance
• Increased efficiency & power
• Environmentally friendly
• Not restricted to CO2
• Significantly smaller size
• Reduced cost
• Supercritical CO2 spans all thermal heat processes for power generation
• Brayton cycle can be used for internal and external combustion

Applications and Industries

• Electric utility
• Nuclear power
• Oil and gas
• Renewable power/energy
