Chiyoda Corporation (Chiyoda), JERA Co. Inc. (JERA) and The Research Institute of Innovative Technology for the Earth (RITE) have commenced technology development and demonstration project of large-scale CO2 separation and recovery from gas-fired power generation exhaust gas, under the New Energy and Industrial Technology Development Organization’s Green Innovation Fund program.
The development and demonstration centers on domestic solid sorbent material to realize low cost separation and recovery of CO2 emitted from gas turbines of gas-fired power plants.
There is an increasing need for gas turbine exhaust gas CO2 separation and storage towards low carbonization in the electric power and LNG supply chain sectors and carbon capture utilization and storage (CCUS). As gas-fired power plants with high combustion efficiency emit low concentrations of CO2, the issues are: (1) High energy input is required for CO2 separation and storage, (2) High equipment and absorption material costs etc., and (3) Large site areas required. Development of technology to realize smaller site areas at low cost is therefore required for full-scale social dissemination and market formation.
This project combines RITE’s knowledge of CO2 separation and recovery technology from blast furnace gas and coal combustion exhaust gas, Chiyoda’s knowledge and experience of process development, scale-up, social implementation and LNG production plant construction and JERA’s knowledge of operation and maintenance of gas-fired power plants, to develop innovative and economical CO2 separation and recovery technology and reduce the required area for gas turbine combustion exhaust gas with 3% to 4% (or less) CO2.
The project will cost approximately 10 billion yen over its nine (9) year schedule from 2022 to 2030 and will be executed in three (3) phases as follows:
Phase 1: Absorbent material development and conceptual design for a commercial plant.
Phase 2: Establish absorbent material manufacturing and construct and operate bench test equipment.
Phase 3: Establish absorbent material mass production and construct and operate a 20 t-CO2 / d scale real gas pilot plant including CO2 Utilization process.
The solutions that Chiyoda, JERA and RITE will provide to achieve low carbonization, while utilizing existing infrastructure and realizing low carbonization utilization of natural gas, are anticipated to be in high demand in Japan and overseas.
