The goal of this project is to further develop the argon power cycle (APC) by using it to demonstrate an ultra-efficient CHP system with a high power/heat ratio. Like other monatomic gasses, argon has a specific heat ratio that is about 25% higher than that of air. Using argon allows the engine to theoretically approach simple cycle energy conversion efficiencies +24% absolute points higher than a traditional air breathing RICE. In a natural gas-fueled APC system, 100% of the carbon dioxide from the exhaust gas is captured, and no air pollutants (e.g., NOx) are generated. Combustion strategies, which are often bound by NOx emission mitigation measures, will be fully optimized for highest conversion efficiency. This provides the flexibility to operate efficiently on hydrogen, effectively rendering the APC a pollution-free power system (no NOx or carbon dioxide).
