The company’s technology combines electrolysis, desalination and hydrogen production on a floating wind platform. It was one of around 20 projects set to move to negotiations with the UK government for support under ‘hydrogen allocation round 1’.
The firm, which plans to accelerate large-scale rollout in the UK, said it had withdrawn its single-unit demonstrator application - “in close collaboration” with the government – to secure alternative funding for a phased multi-unit larger development.
Dolphyn said it would focus on a larger commercial-scale project, with the demonstrator forming phase one of the rollout. To facilitate this accelerated approach, it is moving the demonstrator to a site that will allow expansion at a single location. It did not name the site.
The firm completed the 'proof of concept’ phase in 2020.
The development plan for the project has a target date for the operational start-up of a 2MW prototype facility by summer 2024, to be followed by a 10MW pre-commercial facility by 2027 and full-scale commercialisation shortly afterwards.
Dolphyn is also preparing for offshore hydrogen trials in Milford Haven, south Wales, which will proceed this autumn.
It said it is looking at commercial-scale projects off Scotland in the North Sea, the Celtic Sea off Wales and the Western Atlantic Margin and Celtic Sea off Ireland and is also looking at additional sites in Europe and further afield.
