Centralised offshore hydrogen hubs could facilitate repowering of offshore windfarms
Tractebel unveils offshore hydrogen storage concept
Ability to bundle export and compression of hydrogen produced offshore offers significant cost reductions, engineering consultancy says
Belgium-based engineering consultancy Tractebel says it has developed the world’s first system for large-scale offshore storage of green hydrogen in underground salt caverns. The offshore platform complex consists of a wellhead platform for the operation of the caverns and a series of compression platforms that enable a staged increase in storage, says Tractebel, which is part of French energy group Engie. Underground salt caverns will be used as storage and a buffer for green hydrogen produced offshore, giving increased flexibility, before the gas is transported via the pipeline network to the onshore grid and finally to consumers and customers. The design assumes a capacity equivalent to c
