Research, Development and Demonstration of CCUS Technology

Project overview

Project period: FY2018 to FY2026, FY2022 budget: JPY 8.23 billion

To realize the goal of achieving carbon neutrality by 2050, announced in the Strategic Energy Plan approved by the Japanese Cabinet in October 2021, NEDO will carry out activities in this project related to the research, development, and demonstration of carbon capture, utilization, and storage (CCUS) technologies. These activities include the development of monitoring technologies for the safe storage of CO2 through large-scale demonstration testing and the conduct of surveys on related technologies.

In addition, based on Japan’s Long-term Strategy under the Paris Agreement, NEDO will conduct demonstration testing for transporting captured CO2 to storage and utilization facilities, aiming for the near-term commercialization of CCUS technologies by integrating processes related to CO2 separation, capture, transportation, storage, and utilization.

To realize this goal, the following activities are being carried out:

1. Large-scale CO2 capture and storage (CCS) demonstration testing at Tomakomai

This testing involves separating/capturing CO2 (at a level of approximately 100,000 tons per year) from gas emitted by oil refineries and then storing the CO2 underground at a depth of more than 1,000 meters. Specifically, testing is being carried out on the following: the operation of equipment that separates/captures CO2 at a level of approximately 100,000 tons per year, the injection and storage of CO2 at a level of approximately 100,000 tons per year, and the monitoring of stored CO2.

2. R&D of CO2 storage technologies to safely carry out CCS operations

This R&D activity aims to realize the commercialization of technologies necessary to safely store CO2 on a large scale. Specifically, NEDO is carrying out the following activities: the development of technology to manage the safety of large-scale CO2 injection and storage operations, the development of technology to effectively inject CO2 into large-scale reservoirs, the establishment of conditions for disseminating CCS technologies, and the establishment of CCS-related standards.

3. R&D on CO2 separation/capture technologies

This R&D activity aims to greatly reduce costs associated with CO2 separation/capture by developing commercial technologies in the following areas:

A. Commercialization of advanced solid absorbents for CO2 capture
Using the chemical absorption method, a technology for CO2 separation/capture, plant testing facilities for combustion exhaust gas are employed to conduct research aimed at realizing the commercialization of solid amine absorbents, which enable high-efficiency capture of CO2 emissions.
B. Commercialization of CO2 separation membrane systems
Real gas is used to conduct research aimed at realizing the commercialization of separation membrane technologies effective at separating/capturing CO2 from high-pressure gas generated as a result of coal gasification combined cycle power generation.
