Hydrogen shipping vs submarine cables

Hydrogen transportation and submarine power lines have been compared by an international research team to find out which may be the cheapest option to connect for energy exchange regions separated by the sea. According to their findings, the hydrogen shipping alternative does not present very good prospects of applicability in the future, unless some disruptive technological breakthroughs are made. What makes compressed and liquified hydrogen ships still attractive, however, is that they can export energy almost anywhere, and that electrolysis and liquefaction plants are relatively easy to expand compared to marine cables.
