Hyundai Heavy Industries (HHI), the world’s largest shipbuilder and Korea Electric Power Corporation (KEPCO), a leading utility firm in South Korea, received an Approval in Principle (AIP) for a 2MW Supercritical CO2 (S-CO2) Power Generation System recovering waste heat of a diesel/gas engine from Lloyd’s Register.
The two companies plan to commercialize the next generation S-CO2 system by 2019. S-CO2 is a fluid state of carbon dioxide where it is held above its critical pressure and critical temperature which causes the supercritical state to go beyond liquid or gas into a phase where it acts as both. The S-CO2 system runs generators by utilizing the CO2 as a working fluid for power generation.
Since S-CO2 is denser than the working fluids in gas turbines and steam turbines, the S-CO2 turbine can be designed with roughly 1/3rd size of steam turbines for the same output with 30% increased energy efficiency. The S-CO2 system can use various energy sources including coal-fired power plants, renewable energy, nuclear energy as well as waste heat coming from onshore engine power plants and marine engines of large-sized ships.
