Research, Development and Demonstration of CCUS Technology

Project overview

Project period: FY2018 to FY2026, budget: 7.47 billion yen (FY2025)

To help achieve carbon neutrality by 2050, NEDO is promoting the development of CCUS (Carbon dioxide Capture, Utilization and Storage) technologies. These technologies are designed to capture, transport, effectively use, and storage CO2 emitted from sectors that are difficult to decarbonize—such as steel, cement, chemicals, and oil refining—as well as from power plants.

Research and Development

(1) Large-scale CCUS demonstration testing at Tomakomai

1. Large-scale CCUS demonstration testing at Tomakomai

NEDO conducts CCS demonstration tests to separate and capture CO2 and store it in geological formations at depths of approximately 1,000 m or more below the seafloor. The target of 300,000 tons of CO2 injection was achieved in 2019, and NEDO is currently monitoring the behavior of the stored CO2 as well as conducting marine environmental surveys and other monitoring activities.

2. Demonstration Test on CO2 Transportation

NEDO researches, develops, and demonstrates the technology necessary to construct an integrated marine transportation system that liquefies, stores, loads, and transports CO2 at optimal temperature and pressure conditions, which is one of the means to safely transport large volumes of CO2 separated and captured from exhaust gas at factories and other facilities at the low cost where CCUS is to be implemented.

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

NEDO implements research on the practical application of technologies necessary for the safe practice of CO2 retained on a large-scale level. NEDO will proceed with efforts toward the early introduction of CCS, including (1) the development of technologies for safety management related to large-scale CO2 injection and storage, (2) the development of technologies for effective injection and utilization of large-scale reservoirs, and (3) the development of conditions and standards for CCS dissemination.

(3) Research related to CCUS Technologies

To strengthen the competitiveness of CCUS technology worldwide, NEDO participate in CCUS conferences held by international organizations and conduct research on domestic and international policy and technology trends.
