Hitachi, MOL, and JAL Initiate Japan's First Direct Ocean Carbon Capture Pilot
Hitachi, Mitsui O.S.K. Lines, and Japan Airlines have launched Japan's inaugural Direct Ocean Capture pilot project on Kume Island. This initiative aims to evaluate DOC technology's performance and explore CO₂ utilization in synthetic fuels, supporting the country's decarbonization efforts.

Hitachi, MOL, and JAL have commenced a pilot project for Direct Ocean Capture (DOC) technology on Kume Island, Okinawa. The project will assess the operational efficiency, environmental impacts, and commercial viability of capturing CO₂ from seawater, leveraging the ocean's capacity to absorb atmospheric carbon.
Initial data will inform future carbon credit generation and potential applications for the captured CO₂, particularly in synthetic aviation fuel production. The initiative aims to foster a domestic carbon ecosystem and reduce reliance on imported carbon credits.
Each company contributes specialized expertise, with Hitachi focusing on monitoring and optimization, MOL managing local partnerships, and JAL promoting the initiative within its airline network. This project signals a strategic move towards advancing carbon removal technologies critical for decarbonizing aviation and shipping sectors.
