【Report】Bottlenecks and Risks of CCS Thermal Power Policy in Japan

Renewable Energy Institute has released the English edition of the report Bottlenecks and Risks of CCS Thermal Power Policy in Japan, originally published in Japanese on 14 April 2022.

The goal of 90% electricity generation from renewables by 2050 is widely considered to be the benchmark by countries on the path to achieving a decarbonized society. However, the Japanese government is focusing on developing so-called “zero-emission thermal power” and will continue to use fossil fuel power generation until at least 2050. At the heart of this is thermal power generation equipped with Carbon Capture and Storage (CCS).

This report points out five bottlenecks of relying on CCS, including incomplete CO2 capture, high costs, and limited geographical conditions for CO2 storage in Japan, and introduces how CCS is treated compared to renewables in the global decarbonization strategy, including the latest IPCC report released in April 2022.

The Renewable Energy Institute stated that the goal of this report is to contribute to constructive discussions on the decarbonization of Japan’s electricity supply, as Japanese government is on track to submit a bill to promote the development of CCS in the current parliamentary session, with the goal of making CCS a reality by 2030.
