One of the technologies for achieving carbon neutrality in 2050 is CO₂ capture and storage technology, which captures and stores carbon dioxide (CO₂) in geological formations. Japan CCS Co., Ltd. (JCCS) was established in 2008 by 33 private companies for the purpose of research and development of CCS technology. JCCS has been commissioned to conduct four projects, one of which is a large-scale CCS demonstration project at Tomakomai called the "Tomakomai CCS Demonstration Project." From FY2012 to 2015, the design and construction of facilities, drilling of injection wells, and preparation for demonstration test operations was conducted, and the project achieved 300,000 tonnes of CO₂ injection in November 2019. Thereafter,JCCS has been conducting monitoring, maintenance of facilities, and functional improvements, etc. This report summarizes the outline, results, and achievements of the JCCS Study, commissioned by the Ministry of Economy, Trade and Industry (METI) and the New Energy and Industrial Technology Development Organization (NEDO).
