The owner of shipping company J Lauritzen is backing a new Danish project to produce hydrogen bunkers from wind power.
The research, overseen by Denmark's ShippingLab, will focus at first on converting turbine energy at the port of Hvide Sande into gas for a fuel cell that will power a new dredger there.
This work is envisioned to take a "few years", but beyond that the project has ambitions to make the use of hydrogen commercially viable within shipping in general.
