Kyushu University and Sojitz Corporation (“Sojitz”) have signed a memorandum for the practical implementation and commercialization of direct air capture (“DAC”) and related cutting-edge technologies for directly capturing carbon dioxide emissions from the atmosphere. Kyushu University and Sojitz seek to promote carbon neutral initiatives and provide solutions to social issues through the practical application of cutting-edge technologies towards the realization of a sustainable society.

●DAC is a technology that captures CO2 directly from the atmosphere. Conventional DAC technology uses absorbent or adsorbent-based methods for capturing CO2. However, this method consumes relatively high energy to release CO2 from the absorbents and adsorbents by using heat or by being placed in a vacuum. This high amount of energy used in the process has been considered problematic. Additionally, installation sites for conventional DAC technology are limited due to numerous restrictions of DAC operation requirements.
●The International Institute for Carbon-Neutral Energy Research at Kyushu University (“I²CNER”) has engaged in R&D of the world’s first membrane-based DAC technology, which makes it possible to capture CO2 through a membrane separation system. This new technology will greatly increase the number of possible locations for CO2 capture equipment. In addition, since there is no need to release CO2 from an adsorbent as in the conventional CO2 absorption process, the energy required for the process can be significantly reduced.
●The recovered CO2 can be used as a raw material for fuels and chemicals, as well as for cultivating vegetables and other crops and for beverages and dry ice. This membrane-based DAC technology will expand the range of applications for CO2.
●Kyushu University aims to realize widespread global use of its membrane-based DAC technology and CO2 conversion technology by 2050, and the university is currently involved in the development of a range of technologies for practical implementation.
●Kyushu University proposed to integrate its research plans for membrane-based DAC technology along with its CO2 conversion research, and Kyushu University was selected for the Moonshot Research and Development Program promoted by the Cabinet Office of Japan, which advances ambitious R&D projects based on bold ideas anticipated to have a major impact if realized in a future society. Kyushu University has set its research goal to fully complete development of necessary devices for these technologies by 2030, with hopes to then complete mass production and move forward with implementation.
●Kyushu University and Sojitz were able to conclude this memorandum as part of the university’s current efforts to establish industry-academia collaborations with multiple companies in preparation for implementation.
●This memorandum is based on I²CNER’s world-leading knowledge of CO2 capture, storage, and conversion for achieving carbon neutrality and carbon negativity, as well as Sojitz’s experience from its decarbonization initiatives. Sojitz and Kyushu University concluded this memorandum to pursue possible collaboration and joint cooperation for core technology to be implemented for realizing carbon neutrality and carbon negativity.
●After concluding this memorandum, Kyushu University and Sojitz will promote the R&D of DAC technology utilizing membrane separation based on this industry-academia partnership, hold discussions, and carry out activities with the aim of realizing commercialization.

[Overview of Kyushu University]
Location:Fukuoka, Fukuoka Prefecture
President:Tatsuro Ishibashi

Founded in 1911, Kyushu University specializes in higher education as a research institute with a rich history and tradition. Kyushu University develops talented students who go on to work in Japan and overseas, and the university makes broad contributions to society through its cutting-edge research, medicine, and highly specialized research findings. In 2010, I²CNER was selected by the Ministry of Education, Culture, Sports, Science and Technology (MEXT) under the government’s “World Premier International Research Center Initiative (WPI)”* and nominated as a WPI Academy Center in 2020. I²CNER is the world’s first to include “carbon neutral” within the name of its research institution. (

Based on these successes, Kyushu University launched the Research Center for Negative Emissions Technologies in 2021. Starting with studies on capturing CO2 from the atmosphere, this new research center is engaged in everything ranging from core research related to CO2 resource recycling to the application and implementation of CO2 technologies.  (

* World Premier International Research Center Initiative:
The WPI program aims to enhance Japan’s research functions and strengthen the country’s competitiveness internationally by providing intensive support for Japanese research institutions that aim to gather a core of top-level researchers to become a world-class research institution.
