Decarbonization JGC Begins Development on Carbon Capture Technology Using LNG Cold Energy
A joint project by Toho Gas and Nagoya University aims at the development of technology for CO2 separation, capture, and the like. To support the development and demonstration of this project, JGC Japan will focus on the Cryo-Capture technology which makes use of unused LNG cold energy in CO2 capture from factory exhaust gas.
Kanagawa/Japan – JGC Holdings Corporation has announced that domestic EPC operating company JGC Japan Corporation (JGC Japan) has started technical development on carbon dioxide (CO2) capture applying unused cold energy from liquefied natural gas (LNG).
These efforts support development and demonstration in a joint project of Toho Gas Co. (Toho Gas) and Nagoya University, Tokai National Higher Education and Research System (Nagoya University) that was selected by Japan's New Energy and Industrial Technology Development Organization (Nedo) in May 2022 as a Green Innovation Fund project for development of technology for CO2 separation, capture, and the like. JGC Japan has been contracted by Toho Gas as a participant since September this year.
This development and demonstration is focused on Cryo-Capture technology, which applies unused LNG cold energy in CO2 capture from factory exhaust gas. The R&D builds on the work of Professor Koyo Norinaga of Nagoya University's Institutes of Innovation for Future Society, whose innovative technique for applying unused LNG cold energy to capture CO2 from factory exhaust gas requires only a small amount of additional energy, which promises to reduce CO2 capture costs.
Because natural gas is liquefied by cooling it to roughly -162°C, cold energy is released when LNG is re-gasified at LNG receiving terminals. This underutilized cold energy has attracted attention as a potential energy source for generating power or electricity.
By applying cryogenic expertise acquired from LNG plant/receiving terminal EPC operations, the JGC Group can ensure effective utilization of the unused LNG cold energy. Through test equipment design and other efforts, it will also contribute in verifying the feasibility of practical adoption of this CO2 capture technology. Future contributions may include designing and scaling up pilot plants. Another decisive factor for participating in this development and demonstration is the fact that the JGC Group has positioned carbon neutrality as a key area over the medium to long term and considers CO2 capture an important technology.
In designing test equipment, the firm will consider specific details such as absorbent, equipment, and pressure control methods that suit facility structures and operating conditions based on relationships between nitrogen and other impurities, CO2 concentration, and partial pressure. JGC Japan will provide support in conceptual design for this process and in optimization design for the various facilities involved.
In this way, the JGC Group will continue working toward a carbon-neutral future through corporate and academic collaboration and partnerships to develop innovative environmental technologies.
