Offshore production will be the best way to successfully produce large quantities of green hydrogen without impacting land-based landscapes or relying on an existing grid connection."
From the transport of liquefied hydrogen by ship, boats propelled by electric motors thanks to hydrogen, to the production and storage of green hydrogen at sea, the future of offshore wind and maritime transport could also involve the development of energy storage solutions in the form of H2 gas.
Transporting liquid hydrogen in ships?After the transport of LNG in tankers, ships carrying liquefied hydrogen will soon be arriving on the seas. Shell and GTT, the French technology nugget for membrane containment systems dedicated to the transport and storage of liquefied gases, are embarking on the adventure of hydrogen carriers. The two groups are cooperating to develop technologies to transport liquid hydrogen (LH2) on the seas by 2028. Find out more | ||
Liquid hydrogen cargo ships for zero emission navigation?At the One Ocean Summit, Energy Observer presented a project for a multi-purpose liquid hydrogen cargo ship that would combine very high capacity for transporting containers and vehicles with a long range (up to 4,000 nautical miles - 7,400 km). This large cargo ship is expected to carry 70,000 tons of liquid H2 (1,000 m3) to power a 4 MW electric motor and a 2.5 MW fuel cell pack, enabling it to sail at a speed of 12 knots.

Producing and storing green hydrogen at sea?Several operators such as TOTAL Energy in scotland, Siemens or RWE in Germany are working on the installation of electrolysers at the foot of offshore wind farms to enable the large-scale production of green hydrogen for offshore wind energy storage. In France, the operator Lyfhe and the engineering firm Doris pour are developing Nerehyd, a full-scale demonstrator combining a floating wind turbine with a green hydrogen production unit.

Renewable energy stored at sea?Researchers are studying other alternative solutions to Hydrogen to store electricity at sea, as close as possible to the wind turbines, to reduce the cost of connecting offshore wind farms to the terrestrial networks and improve the flexibility of the electricity supply. Energy storage on floating wind farms, independent of the grid and located far from the coast, could also meet the future needs of a "zero emissions" maritime transport. Find out more |  |
