Report on Large-scale CCS Demonstration Project Compiled

May 15, 2020

Note: Summary of the Comprehensive Report (English version) was posted on May 29, 2020

In November 2019, the Ministry of Economy, Trade and Industry (METI) achieved the goal of successfully injecting 300,000 tons in total of carbon dioxide (CO2) underground under the Large-scale CCS Demonstration Project in Tomakomai City, Hokkaido Prefecture. Following this, in light of the discussion results of experts in a wide variety of fields, such as mechanical engineering, chemical engineering, geology and geophysics, METI compiled the results of and challenges in the project which were found as of the successful injection of 300,000 tons of CO2 underground into a report titled “Report on the Large-scale CCS Demonstration Project in Tomakomai City as of the Successful Injection of 300,000 tons of CO2 Underground” (hereinafter referred to as the “Comprehensive Report”) and hereby announces the report.

1. Outline of the CCS technology

Carbon dioxide Capture and Storage (CCS) is a technology to collect CO2 emitted from manufacturing plants, power stations and other facilities before release and dispersion of such CO2 to the atmosphere and to store the collected CO2 underground. In its Long-Term Strategy under the Paris Agreement as Growth Strategy, a compilation on which the Cabinet Decision was made in June 2019, Japan has positioned CCS as a technology that “Japan should develop toward the introduction of CCS by 2030 on the premise of its commercialization, in particular for coal-fired power generation”.

2. Overview of the Tomakomai CCS Demonstration Project

  1. From FY2012 to FY2017, METI commissioned its Demonstration Project for Technologies for Reducing Carbon Dioxide to Japan CCS Co., Ltd. and it conducted the demonstration project in Tomakomai City. For two years from FY2018 to FY2019, the project was undertaken as part of the NEDO CCS Research and Development-Related Project: Large-scale Demonstration Project in Tomakomai City, to which the New Energy and Industrial Technology Development Organization (NEDO) granted funds.

  2. For four years from FY2012 to FY2015, the project designed and constructed necessary facilities and conducted research. From April 2016, setting a goal of 100,000 tons of CO2 injection per year, the project started injection of CO2 to underground layers at nearly 1,000m and nearly 2,400m below the seabed, and on November 22 (Fri.), 2019, the project finally reached the goal of 300,000 tons of CO2 injection in total.

3. Outline of the Comprehensive Report

  1. In light of the results of discussions of experts in a wide variety of fields, such as mechanical engineering, chemical engineering, geology and geophysics, based on the successful achievement of the goal of injecting 300,000 tons of CO2 underground, METI compiled the results of the project and challenges it faces into the Comprehensive Report.

4. Future schedule

  1. The project will continue monitoring and other efforts, including observing very small oscillations in the areas surrounding the reservoir point, surveying marine environments and checking behaviors of injected CO2, e.g., displacement and spreading.

  2. The project will conduct a demonstration test for carbon recycling, e.g., methanol synthesis, effectively taking advantage of the facilities for the CCS Demonstration Project, and advance establishing a base for demonstration of CCS and carbon recycling in Tomakomai City.

  3. According to the Long-Term Strategy under the Paris Agreement as Growth Strategy and other policies, METI will continue to advance domestic efforts for the project while obtaining understanding and cooperation from the municipality and local stakeholders in Tomakomai City, and also advance international collaboration as well as dissemination of Japan’s CCUS (Carbon dioxide Capture, Utilization and Storage) technology in overseas countries.
