German chemical firm BASF has announced that the high-pressure regenerative CO2 capture technology HiPACT co-developed by BASF and its engineering partner JGC Corporation will be used by Inpex Corporation, one of Japan’s largest exploration and production companies in its Kashiwazaki Clean Hydrogen/Ammonia Project.
This is Japan’s first demonstration project for the production of blue hydrogen/ammonia from domestically produced natural gas, the consistent implementation of Carbon Capture, Utilisation and Storage (CCUS) in domestic depleted gas fields and the use of hydrogen for power generation and ammonia production. The project is funded by the Japanese governmental organization New Energy and Industrial Technology Development Organization (NEDO).
The HiPACT technology will be applied to efficiently capture and recover CO2 in the process gas from a hydrogen production facility using domestic natural gas as feedstock. Located in the Hirai area of Kashiwazaki City, Niigata Prefecture, Japan, the production facility is constructed by JGC Japan Corporation and is expected to start up in 2025. The recovered CO2 will be injected into the reservoirs of the depleted gas fields leveraging CCUS technologies for enhanced gas recovery (EGR).
By releasing the CO2 off gas above atmospheric pressure, HiPACT is expected to reduce CO2 capture and compression costs by up to 35% compared with conventional technologies. This is due to its excellent high-temperature durability and CO2 absorption performance. As CO2 can be stored underground in an energy-saving manner, maximum benefits are expected for Carbon Capture and Storage (CCS).
Mami Kawakatsu, Head of Sales, Intermediates Division of BASF Japan, said, “Following the successful use of BASF’s OASE gas treating technology in another NEDO-funded CCS project in Tomakomai, Japan, we are pleased to provide HiPACT for Japan’s first demonstration project to produce blue hydrogen and ammonia from domestic natural gas. The role of our excellent gas-treating technologies is recognized in these milestone projects in Japan’s net zero roadmap. We will continue to contribute to Japan’s 2050 carbon neutrality goal.”
BASF’s gas treating technologies have been used in more than 500 reference plants worldwide, and the company has more than 50 years of experience in this field. OASE is a CO2 capture technology for a wide range of applications, including natural gas, synthesis gas, flue gas and biogas.
HiPACT is a specialised solution targeting natural gas and synthesis gas treatment equipped with CCS or with CO2- Enhanced Oil/Gas Recovery (EOR/EGR).
