JAL joins pilot test to capture CO2 from seawater

Japan Airlines (JAL) announced that it has joined Hitachi and Mitsui O.S.K. Lines in signing an agreement to run Japan’s first pilot test of a technology that pulls carbon dioxide directly out of seawater.  The companies announced on August 4, 2026 that the test will take place on Kume Island in Okinawa Prefecture. The technology, known as Direct Ocean Capture, works by separating and removing CO2 that’s already dissolved in ocean water.  For th…

Japan tests whether carbon pulled from seawater can fuel planes

A remote Japanese island could become a testing ground for a new kind of carbon economy, one that begins by extracting carbon dioxide from seawater and could eventually supply verified carbon-removal credits or raw material for synthetic aviation fuel. Hitachi, Mitsui O.S.K. Lines and Japan Airlines have signed an agreement to conduct a direct ocean capture pilot on Kume Island in Okinawa Prefecture. The immediate goal is relatively narrow. The …

Marine carbon removal technology that turns carbon dioxide in seawater into 'stone' for permanent storage

A research team led by Professor Dong-Yeun Koh of the Department of Chemical and Biomolecular Engineering, in collaboration with Professor T. Alan Hatton's group at the Massachusetts Institute of Technology (MIT), developed an electrochemical dissolved ocean carbon removal (e-DOC) technology that converts carbon dioxide dissolved in seawater into calcium carbonate (CaCO₃), a stable mineral form that enables virtually permanent carbon storage.
