UK business leaders and politicians have welcomed the signing of a new agreement which will create a new future for offshore wind energy in the North Sea.

The UK signed a “historic” clean energy security pact – the Hamburg Declaration – with European nations to bolster energy security for families and businesses across the UK and Europe, in an era of global instability. The declaration has been  signed by energy ministers from Belgium, Denmark, France, Germany, Iceland, Ireland, Luxembourg, the Netherlands, and Norway.

The deal is designed to drive forward an “unprecedented fleet of joint offshore wind projects” between European countries, including Germany, Norway, France, and Denmark, taking advantage of Europe’s shared abundant energy in the North Sea.

Three years ago, North Sea countries pledged to build 300 GW of offshore wind in the North Sea by 2050, in response to Putin’s illegal invasion of Ukraine and weaponisation of Europe’s energy supplies.

The UK government added the deal means, for the first time, North Sea countries have agreed to deliver 100 GW of this offshore wind power through joint clean‑energy projects. These will include new ‘offshore wind hybrid assets’ – wind farms at sea that are directly connected to more than one country through interconnectors. This joint commitment is set out in the ‘Hamburg Declaration,’ agreed today at the Future of the North Seas Summit.

UK energy secretary, Ed Miliband, said:  “We are standing up for our national interest by driving for clean energy, which can get the UK off the fossil fuel rollercoaster and give us energy sovereignty and abundance.

“After our record renewables auction, we today went further by signing a clean energy security pact with European allies to ensure we maximise the clean energy potential for the North Sea.”

Further key outcomes expected from the summit include:

• Interconnected offshore grid – the Energy Secretary signing a statement of intent with Germany, Belgium, Denmark, the Netherlands to unlock cross-border offshore electricity projects, focusing on joint planning, cost-sharing, and market arrangements to speed up delivery.
• Offshore Hybrid Assets – The UK agreeing a framework to deepen German and UK collaboration on offshore hybrid assets. These are advanced subsea energy infrastructure that combine offshore wind farm connections with electricity interconnectors. This would put UK firms at forefront of grid technology, unlocking export opportunities and boosting growth.

Ben Wilson, President of the |UK’s National Grid Ventures, said: “Today is a step towards a more integrated energy system in the North Seas. LionLink and projects like those being announced today are important for maximising the efficient use of resources, reducing costs, and minimising the impact on coastal communities. Collaboration on projects like these are key to delivering on more secure, affordable energy for British and European consumers.”

Tania Kumar, Energy Transition Director, at the CBI, said: “As global instability continues to expose the vulnerabilities of fossil fuel dependence, the Hamburg Declaration sends a clear signal that international cooperation is central to strengthening energy security and accelerating the shift to clean power.

“By partnering with our European neighbours to deliver joint offshore wind projects in this historic pact, the UK is sharing its world leading expertise and helping unlock the vast clean energy potential of the North Sea.

“These collaborative developments will lower costs for consumers, create jobs across the economy, and give industry the long-term certainty to invest and innovate. Just as importantly, they showcase to countries globally the tangible benefits of expanding clean energy generation.”

Dhara Vyas, chief executive of Energy UK, said: “The UK’s energy sector is fully behind the landmark efforts to be announced at the Hamburg North Sea Summit to transform the North Sea into a truly regional clean power hub. Delivering the goal of 100 GW of offshore cooperation projects by 2050 will require a relentless focus on maintaining the momentum of UK-EU alignment on electricity market coupling and ETS linkage.

“This deeper cooperation on supply chains, standardisation, and shared infrastructure is not just a strategic necessity, it is the most effective way to bring down energy costs for households and businesses while fuelling sustainable economic growth and high-value jobs for years to come.”

Jane Cooper, Deputy Chief Executive of RenewableUK, commented:  “This ambitious announcement to build a vast number of new offshore wind farms jointly with our European partners will increase the energy security of the UK and the whole of the North Sea region significantly. This historic declaration puts offshore wind right at the heart of Europe’s power system, with the UK leading the way.

“We are strengthening our security collaboration to ensure the North Sea’s critical energy infrastructure is protected from harm, so that we can continue to generate the huge quantities of clean power needed by the UK and our neighbours reliably at all times.”

William Bain, head of trade policy at the British Chambers of Commerce, said: ”It is essential for the UK’s energy security and economic growth that we co-operate more closely with our European allies to realise the full potential of the North Sea.

“The commitments set out in the Hamburg Declaration will deliver on that, allowing our businesses to work on joint projects on renewables, interconnectors, and other vital energy infrastructure. The momentum from today’s Summit and Business Conference needs to be kept up.”
