日揮グループのサステナビリティとCCUSに関する取り組み

抄録

The JGC Group has built a reputation as a leading contractor in CCS. Our track record of construction includes projects such as our first CCS facility at an Algerian natural gas refinery in 2004, a CCS installation at an Australian LNG plant that is one of the world’s largest, and one of Japan’s first large-scale CCS pilot projects in Hokkaido. Along with construction of CCS facilities, JGC is actively developing technologies used in CO₂ separation. With NGK Insulators, Ltd., we have developed original CO₂ separation and capture technology applying DDR-type zeolite membranes, which are being tested in preparation for commercial deployment at plants. This technology offers higher CO₂/CH₄ selectivity than with conventional polymeric membranes, and the membranes’exceptional durability in high- pressure, high-CO₂ environments makes them promising in CO₂-EOR（enhanced oil recovery）. Another technology for which JGC is involved in sales and has already licensed at CCS facilities outside of Japan is HiPACT ^®, which recovers CO₂ at high pressures from natural gas and synthesis gas, enabling cost reduction and energy saving in CCS. HiPACT ^® was jointly developed by the JGC Group and BASF. JGC Group is promoting maturation and commercializing of technologies that contribute to sustainability through collaborative innovation, with “Enhancing planetary health” as its own purpose. This keynote introduces our efforts in the areas of Sustainability and Carbon Capture, Utilization and Storage Projects.
