News media caught a glimpse of a vessel that carries liquefied carbon dioxide in the carbon capture and storage process, or CCS. The system ends in the long-term storage of collected carbon dioxide deep underground.

The 72-meter ship unveiled in Yokohama City has two tanks that can carry 850 tons of liquefied carbon dioxide.

Stable transportation of large amounts of carbon is a key issue in turning the CCS process to practical use. The New Energy and Industrial Technology Development Organization, or NEDO, is set to demonstrate the practicality of moving liquefied carbon this October. It will run between Japan's northernmost prefecture of Hokkaido and Kyoto Prefecture in the west.

NEDO plans to perfect the transportation technology by fiscal 2026. It also aims to introduce a vessel capable of carrying up to 70,000 tons of CO2 in the future.
