Investigation of offshore thermal power plant with carbon capture as an alternative to carbon dioxide transport

Carbon Capture and Storage (CCS) technology is considered to be one option to reduce CO2 emissions in order to mitigate climate change. Conventional CCS technology has its own complexities including high costs and risks for storing CO2. This paper introduces the concept of an Offshore Thermal Power Plant with CCS (OTPPC), which eliminates the needs for transporting CO2 and therefore reduces the complexities of the whole system. A general design selection process for the OTPPC is established. A case study is carried out to demonstrate the application of the OTPPC. The cost-effectiveness of this concept is evaluated by calculating the Levelised Cost Of Energy (LCOE) for both the OTPPC and conventional CCS technology for an onshore power plant with the assumption that CCS is necessary.
