Investment prospectus puts Pembrokeshire at heart of £20bn clean energy drive
Haven Waterway set to become major hub for wind, hydrogen and port jobs as Wales launches investment prospectus
PEMBROKESHIRE could be in line for billions of pounds of new energy investment after a major national strategy identified Wales’ ports and heavy industry heartlands as key to unlocking more than £20bn in clean infrastructure projects over the next decade.
A new Clean Energy Investment Prospectus published this week by Net Zero Industry Wales sets out a pipeline of “investible” projects across offshore wind, hydrogen, industrial decarbonisation, ports and data centres — with the Haven Waterway widely seen as one of the most attractive locations in the country.
Industry experts say Milford Haven and Pembroke Dock already have the deep-water access, grid connections and industrial land needed to host the next generation of energy schemes.
The Herald understands that several projects linked to floating offshore wind assembly, hydrogen production and port upgrades are being explored locally as part of the wider push.

Jobs and contracts
The Prospectus acts as what organisers call a “one-stop shop” for global investors, bringing together sites, policy support and funding routes.
For Pembrokeshire, that could mean:
- port expansion and quay strengthening
- turbine assembly and maintenance bases
- marine engineering and fabrication work
- hydrogen and low-carbon fuel plants
- construction and long-term skilled jobs
Floating wind alone is expected to create thousands of roles across Wales during construction and operations, with much of the heavy lifting likely to happen in west coast ports.
With the Celtic Sea tipped to become one of Europe’s largest floating wind zones, Pembrokeshire’s existing energy infrastructure gives it a head start.
Major players already circling
Recent Welsh Government announcements linked to the programme include commitments and interest from global firms such as RWE, Eni, and Vantage Data Centres.
Support is also available through bodies including the Development Bank for Wales, aimed at helping projects move quickly from planning to delivery.
Ben Burggraaf, chief executive of Net Zero Industry Wales, said Wales offered “a unique combination of natural competitive advantages and industrial capability”.
He added: “We have significant clean energy resources, a strong industrial base, and a large and diverse pipeline of projects backed by credible organisations and skilled people — giving investors both scale and opportunity to make a real difference.”
Government backing
Wales’ Cabinet Secretary for Economy, Energy and Planning, Rebecca Evans, said the country was “primed to capitalise on the UK’s clean energy revolution”.
She said: “By working together with developers and stakeholders we can boost our economy and achieve our renewable energy targets for Wales.”
Why Pembrokeshire fits the bill
Energy analysts say few places in the UK combine:
- two LNG terminals
- deep-water shipping access
- heavy industry and engineering skills
- available dockside land
- existing power connections
All of which are already present around the Haven.
That makes the area particularly attractive for assembling massive floating wind structures and servicing turbines once operational.
Local businesses — from steel fabricators to haulage firms and electricians — could benefit from supply-chain work if even a fraction of the promised investment lands in the county.
Long-term impact
While the £20bn figure covers the whole of Wales, insiders say west Wales stands to gain disproportionately because large-scale energy schemes simply cannot be built inland.
For Pembrokeshire, the Prospectus signals that the Haven Waterway’s future may be as a green energy powerhouse rather than a traditional fossil fuel hub.
If realised, it could reshape the county’s economy for a generation.

New deal aims to unlock Wales’ renewable energy potential
Sector partnership targets 100% renewable electricity by 2035
A NEW deal has been launched to help Wales meet its renewable energy targets while ensuring greater benefits for local communities.
The Renewable Energy Sector Deal will see the Welsh Government and industry work in strategic partnership to unlock the full economic potential of Wales’ renewable energy future.
The announcement coincides with the publication of the latest Energy Generation and Energy Use in Wales report, which shows renewable electricity generation in 2024 was equivalent to 54% of Wales’ electricity consumption.
The Welsh Government has set a target for renewable electricity to meet 70% of demand by 2030 and 100% by 2035. It also aims to deliver at least 1.5 gigawatts of locally owned renewable energy capacity by 2035.
The Sector Deal is intended to accelerate deployment across onshore and offshore wind, solar, marine and hydro projects. It will also focus on strengthening supply chains, developing skills, and ensuring communities across Wales benefit directly from renewable energy developments.
Cabinet Secretary for Economy, Energy and Planning, Rebecca Evans, is launching the deal during a visit to the Morlais tidal energy project on Anglesey.
The Morlais scheme, owned and managed by social enterprise Menter Môn, is set to become the largest consented tidal energy project in Europe. The Welsh Government holds an £8 million equity stake in the project.
Rebecca Evans said: “Our ambition is to become a world leader in renewable energy, creating jobs and green growth to make families in Wales more prosperous and help with the cost of living.
“The current conflict in the Middle East has further highlighted the importance of energy independence. Our Renewable Energy Sector Deal will provide a strong foundation for future delivery, benefiting our economy, environment and energy security.
“The Morlais project shows how sustained partnership can unlock Wales’ natural energy resources and turn them into lasting economic opportunities for local communities and businesses.
“The latest energy report shows we are making progress towards our targets. Combined with the record 20 major renewable projects, totalling 1,400MW, backed in the most recent UK Government Contracts for Difference auction, it is clear we are building a more resilient, renewable-powered future.”
Dafydd Gruffydd, Managing Director of Menter Môn, added: “The Renewable Energy Sector Deal is an important step in accelerating growth in Wales and across the UK.
“It recognises the role marine energy schemes like Morlais can play in strengthening energy security, creating high-quality jobs and delivering long-term economic benefits for communities such as Anglesey.”
The Sector Deal was co-produced by a task and finish group made up of developers and community organisations.
Responding to the Welsh Government’s Renewable Energy Sector Deal, Welsh Liberal Democrat Leader Jane Dodds MS said: “This so-called ‘sector deal’ raises more questions than it answers.
“There is no clear plan for how we build the workforce needed, with no detail on training, skills or apprenticeships to deliver the green jobs Wales needs.
“Ministers also promise benefits for communities, but without minimum standards or enforcement, there is no guarantee local people will see the rewards.
“Most concerning is the lack of focus on energy bills. Families are struggling, yet there is no clear explanation of how this will bring down costs. Renewable energy should mean cheaper bills, but as long as electricity prices are tied to gas, households won’t feel the benefit, something Labour in Westminster has failed to fix.”

Research vessel begins mission to study seabed carbon in Irish Sea
Bangor University scientists join £2.1m project investigating the impact of bottom trawling on carbon stored beneath the seabed
A STATE OF THE ART research vessel has set sail from Liverpool to investigate how bottom trawling may affect carbon stored in the seabed of the Irish Sea.
The scientific expedition is part of a £2.1 million research project funded by the Natural Environment Research Council and led by Professor Jan Geert Hiddink of Bangor University.
A team of eighteen scientists has embarked on the RRS Discovery, one of the world’s most advanced research vessels, for a three-and-a-half-week voyage studying the impact of fishing activity on carbon held in seabed sediments.
Before the ship departed, a number of local dignitaries were invited aboard for a tour of the vessel, including Liverpool City Region Mayor Steve Rotheram and National Oceanography Centre Operations Director Natalie Campbell.
Professor Jan Geert Hiddink, from Bangor University’s School of Ocean Sciences, said bottom-trawl fishing is both vital to global food supply and a major disturbance to seabed environments.
“Bottom-trawl fishing provides around a quarter of global seafood but is also the most extensive physical disturbance caused by human activities to stocks of carbon locked in seabed sediments,” he said.
“This is important because recent evidence suggests that disturbing the seabed could lead to the release of significant amounts of greenhouse gases from the seabed into the atmosphere.
“There are still major uncertainties about how this disturbance affects carbon stored beneath the seabed. As a result, the impact of these disturbances is largely unquantified and currently unregulated.
“The aim of this project is to gain a much clearer understanding of what is happening so that scientists, policymakers and regulators can make informed decisions in the future.”
Seven research organisations are collaborating on the project: Bangor University, the Centre for Environment, Fisheries and Aquaculture Science (CEFAS), Heriot-Watt University, the University of Leeds, Plymouth Marine Laboratory, the University of St Andrews, and Imperial College London.

Green hydrogen plant approved for Milford Haven Freeport site
Major investment expected to boost low-carbon industry and create skilled jobs in West Wales
A MAJOR green hydrogen project planned for the Milford Haven Freeport tax site has taken a significant step forward after developers approved the final investment decision.
Energy company MorGen Energy has confirmed it will proceed with the West Wales Hydrogen project, one of the first schemes backed through the UK Government’s Hydrogen Allocation Round (HAR1) to reach this stage.
The facility will be built within the Milford Haven Tax Site, part of the Celtic Freeport zone covering Pembrokeshire and Neath Port Talbot.
Construction is expected to begin in 2026, with the plant scheduled to become operational in early 2028.
Once completed, the site is expected to produce around 2,000 tonnes of low-carbon hydrogen each year, meeting the UK’s Low Carbon Hydrogen Standard.
The hydrogen produced will support a range of industries, including port operations, manufacturing and industrial heating, as well as use as a chemical feedstock.
Supporters say the development will help reduce carbon emissions while strengthening Milford Haven’s role in the UK’s emerging hydrogen economy.
The project is also expected to create skilled jobs and provide work for local contractors during the construction phase.
Further expansion may be possible in future phases as demand for hydrogen grows, potentially helping establish Milford Haven as a major hub for low-carbon energy production serving South Wales and beyond.
Luciana Ciubotariu, Chief Executive of Celtic Freeport, said the decision marked another milestone for the region.
She said: “MorGen Energy’s decision is another major step forward for the hydrogen economy in South West Wales.
“Projects like this within the Milford Haven Tax Site show how the Celtic Freeport is accelerating decarbonisation while creating high-value jobs.”
The UK Government’s Hydrogen Allocation Round scheme provides revenue support to help scale up the country’s low-carbon hydrogen sector and bring early projects to market.
