MOL hydrogen project selected for Shiga prefecture subsidy program

Mitsui O.S.K. Lines, Ltd. announced that its initiative to develop a pure water production system for #hydrogen generation has been selected for a Shiga Prefecture-backed project to promote social implementation of near-future technologies.

#MOL is promoting the Wind Hunter Project , which harnesses offshore wind energy to produce hydrogen from water onboard and convert it into propulsion for vessels, to realize a decarbonized, hydrogen-based society. However, hydrogen production requires a higher level of water purity, even more than drinking water. During the Wind Hunter hydrogen production process, seawater is first purified by passing it through a filter to remove impurities such as organic matter (carbon content, microplastics, etc.), inorganic matter (iron, magnesium, sodium), and sludge, but the filters currently in common use require frequent replacement, which increases the workload of crewmembers and imposes a significant cost burden.

The development of more efficient onboard technology to produce pure water from seawater in the Wind Hunter project will mark a major step toward the realization of large zero-emission ships, MOL stated.
In this project, a pure water production system will be designed not only for seawater but also for fresh water through a demonstration test in Lake Biwa in Shiga Prefecture. MOL will assess the effects of differences in water quality and establish a versatile pure water production technology by comparing seawater with fresh water from Lake Biwa, the largest lake in Japan. It will not only create pure water production technology for the Wind Hunter project, but also apply the developed technology to supply pure water to hydrogen production plant and other applications.
