Global sustainability consultancy ERM has launched offshore trials to evaluate crucial elements of its Dolphyn Hydrogen process at Pembroke Port, Wales. These trials, after six years of development, represent a significant step towards large-scale low-carbon hydrogen production in the UK. The hydrogen sector is accelerating its development in the UK, as illustrated by the joint project led by Lhyfe and Centrica. What’s more, the wind power sector, whether hydrogen-powered or not, is also benefiting, and we’re seeing a major expansion in wind power infrastructures.
The Dolphyn Hydrogen process integrates electrolysis, desalination and hydrogen production on a floating wind platform. The hydrogen produced is piped ashore for various industrial uses, without the need for connection to the power grid, thus eliminating the associated constraints.

Government funding and support

The development of the Dolphyn Hydrogen process is financially supported by the UK government’s Department for Energy Security and Net Zero, as part of the Low Carbon Hydrogen Supply 2 Competition, part of the £1 billion Net Zero Innovation Portfolio (NZIP). To date, over £8 million has been allocated to the project, which is also supported by the devolved governments of Wales and Scotland.
ERM has assembled a team of experts in engineering, safety, permitting and stakeholder engagement. A digital twin, using ERM’s emissions.AI, is integrated to optimize energy efficiency and minimize emissions during testing.

Objectives and outlook

The trials underway at Pembroke Port aim to demonstrate the technical and economic viability of low-carbon hydrogen production offshore. This project could pave the way for wider adoption of hydrogen in various industrial sectors in the UK, reducing dependence on traditional energy sources.
The results of these tests will determine the next steps in the commercial deployment of the Dolphyn Hydrogen process. If the trials are successful, they will accelerate the development of the infrastructure needed to support large-scale hydrogen production.
