**Pembroke Dockyard Set to Host Innovative Green Hydrogen Facility in Major Clean Energy Push**
A revolutionary clean energy project is poised to transform Pembroke Dockyard, following the recent approval of a new green hydrogen production plant in the coastal community. Pembrokeshire Council has granted planning permission for the development of a 15-megawatt facility, a move likely to bolster the region’s ambition to become a leading player in the renewable energy sector.
The initiative is helmed by Haush Ltd, a company specialising in sustainable energy solutions. The planned site, situated at Gate 4 of Pembroke Dockyard, will feature a range of high-tech infrastructure, including state-of-the-art electrolysers, advanced compressors, a substation, and all associated works required for operation. The facility will tap into the national grid for its power, utilising an 11kV connection to deliver electricity from renewable sources.
What sets this project apart is its focus on green hydrogen, a fuel increasingly championed as a critical tool in the battle against carbon emissions. Unlike conventional hydrogen production, which relies heavily on fossil fuels, green hydrogen is produced via electrolysis—the process of splitting water molecules into hydrogen and oxygen using electricity derived from renewables. This method ensures that no greenhouse gases are emitted during production, aligning cleanly with both local and national net-zero targets.
Locogen Consulting Ltd, a prominent Edinburgh-based consultancy in the renewables sphere, outlined the broader aims of the project. In an official statement, the consultancy emphasised Haush Ltd’s commitment to tackling emissions in sectors such as transport and construction, which remain some of the toughest to decarbonise. “Haush’s vision is to meet some of the most pressing challenges of our time—decarbonising crucial industries. Their approach hinges on working collectively with communities to produce green hydrogen, a clean and sustainable fuel that can significantly drive down carbon emissions,” the statement read.
The consultancy further highlighted that the project aims to identify and serve those regions in the UK where hydrogen could make the greatest difference. With its strategic setting and existing infrastructure, Pembroke Dockyard was evaluated as the ideal location, supporting the wider push for Pembroke Dock Marine to emerge as a global centre for marine energy and low-carbon innovation.
Observers note that this transformative project is not only a vote of confidence in Pembrokeshire’s energy sector, but also a major step towards diversifying the region’s economic and industrial base. The local authority believes the facility’s construction and eventual operation will complement ongoing renewable developments in the area, including wind and tidal energy schemes.
Key details revealed in the planning documents include logistical elements surrounding the plant’s operations. The facility is expected to generate up to six heavy goods vehicle (HGV) movements daily, with each vehicle requiring approximately five hours to be fully refuelled. This relatively modest number of vehicle journeys is expected to limit disturbance and ensure efficient site management.
Safety, a frequent concern with hydrogen facilities, has been carefully addressed in the approved plans. Developers have opted for an innovative production system in which hydrogen is made and compressed on demand, immediately transferred offsite using specialised tube-trailers owned and operated by Haush Ltd. Notably, there will be no permanent onsite storage of hydrogen, a decision designed to further reduce risk and assuage community worries around potential hazards.
While conditional planning consent has now been awarded, full construction timelines and commissioning dates will be determined as the project advances through the next stage. The local council and other stakeholders will continue to monitor progress, underscoring the region’s determination to be at the forefront of the UK’s green energy revolution.
This development marks another milestone for Pembrokeshire as it builds on its legacy as a centre for maritime activities. By embracing forward-looking energy technologies, the dockyard and surrounding region could soon find itself at the heart of the national push towards a cleaner, more resilient energy future.
