Two Japanese firms are looking to develop a carbon capture and storage (CCS) value chain between Japan and US' Alaska state to help achieve Japan's 2050 decarbonisation goal.
Japanese trading house Sumitomo and Japanese shipping firm Kline today reached a deal to sign a joint research agreement with US independent Hilcorp, for a strategic partnership to capture CO2 in Japan and transport it on a large liquefied CO2 (LCO2) carrier to storage and injection facilities in Alaska.
Oil and gas fields have been developed in Alaska since the 1950s and the total storage capacity of the CCS project is expected to be 50 gigatonnes, equivalent to 50 years' worth of Japan's CO2 emissions, Sumitomo said. The world's first LCO2 transportation for CCS is scheduled to start next year ahead of this project, Kline said.
Japanese companies are gearing up efforts to seek overseas storage sites for CO2, as domestic storage sites would be insufficient to store all of the country's possible emissions. Tokyo aims to add 6mn-12mn t/yr of CO2 storage capacity domestically and internationally from 2030, with a target of 120mn-240mn t/yr by 2050.
The government has projected that Japan will be able to store up to 70pc of its forecasted CO2 emissions of approximately 240mn t/yr in 2050. Japan's parliament in May allowed the government to ratify the 2009 amendment to the International Maritime Organization's London Protocol that will enable the export of CO2.
