Green hydrogen: a future energy source for port cities?

 Energy transition and circular economy 

The future seems to lie with “green” hydrogen, made from non-fossil based electricity. It would require a virtuous chain between renewable energies and hydrogen production plants, to which city-port ecosystems are particularly suited.
In that vein, the Port of Bordeaux (France) has signed an agreement to develop a green hydrogen production industry locally. It is a similar story in Bilbao (Spain), where the port authority has given the go-ahead for construction of one of the world’s largest green hydrogen plants.
These industries are often organised in the form of hubs like the one at Port Kembla (New South Wales Port Authority, Australia, helping to stimulate the local economy.
Mass-produced hydrogen could power ships and help to improve the environmental footprint of maritime shipping. To that end, some companies are researching hydrogen-based propulsion systems, including Engie and ArianeGroup which have joined forces. Prototypes of hydrogen engines are even now being tested by the Italian company Fincantieri.
There is a real market for this new fuel, as can be seen with the agreement that will see Portugal supply green hydrogen to the Port of Rotterdam, which needs the resource for its future operations.
