At the North Sea Summit in Hamburg, European leaders pledged to turn gray waters into a green engine, hardening industry against global shocks. Their plan aims to de-risk grids and shield them from economic and political turbulences, theoretically ending the era of costly energy imports, writes Henry McCaw.

Yet, political ink cannot keep the lights on. With the EU still leaning on foreign imports for 60% of its energy, the old world of tankers and pipelines is no longer fit for purpose. To rebuild its backbone, the region must do more than plant turbines; it must re-wire itself. This requires expanding the “connective tissue” of the grid and treating green power as a hard industrial necessity rather than a policy experiment.

This shift is already gaining pace as high-level diplomacy gives way to industrial execution. Leading this charge are the wind and solar markets, which have almost reached a state of maturity and now serve as the proven, high-capacity anchor for Europe’s new energy landscape.

Wind and solar come of age

To speak of energy sovereignty today is to speak of renewables; no other path remains. The European Union has crossed a watershed, proving that wind and solar are no longer mere “alternatives” but the bedrock of a self-reliant era. In 2025, solar became the bloc’s top power source. Combined with wind, these forces generated 30.1% of EU electricity—finally unseating fossil fuels, which fell to 29%.

This crossover ends the experimental phase. By late 2025, nearly half of the EU’s net power flowed from renewables. What began as a policy nudge has surged into a self-driven engine. State support served its purpose as a starter motor; today, private power players have shed their roles as subsidized newcomers to become the primary drivers of growth.

The struggle has now shifted from merely planting turbines to the grit of system integration. Private operators are at the helm, knitting together the cross-border links and flexible backup power a modern grid demands. This maturity allows Europe to cast off fickle gas imports for good. Nowhere is this clearer than in the rise of the industrial pioneers currently turning these goals into a working reality.

The GigaBattery Jänschwalde 1000: Industrializing the transition

The GigaBattery Jänschwalde 1000 serves as a loud signal that wind and solar power have outgrown their infancy. This is no longer a trial run; it is a full-scale shift. By turning a former coal heartland into a high-tech hub, partners LEAG and Fluence have shown that the green transition can breathe new life into old industrial bones. Their project, which hooked up 1 GW/4 GWh of storage to the grid in late 2025, proves that the real fight for energy independence now hinges on a stronger, smarter grid and the ability to store power for a rainy day.

This massive battery acts as a shock absorber for the system. In the past, heavy coal plants provided the steady “inertia” needed to keep the grid stable; today, AI-driven battery banks do that job faster and cleaner. They soak up sun and wind when it is plentiful—preventing good energy from going to waste—and feed it back when the clouds gather or the wind dies down. Jänschwalde proves that with enough of this flexible backing, renewables are finally ready to provide the round-the-clock reliability needed to run Europe’s factories and mills.

NeuConnect: Building the invisible supergrid

On a continental scale, the €2.8 billion NeuConnect interconnector further illustrates that wind and solar power have moved beyond national boundaries to anchor a full-scale energy transition, and creates the first direct link between the British and German energy markets. Steered by Meridiam, the lead developer and investor, who brings the seasoned professionalism needed to coordinate a global consortium including Allianz and Kansai Electric Power, this “invisible energy highway” demonstrates why expanding the electricity grid and its cross-border connectivity is vital to smoothing out the whims of the weather across the North Sea, says Julia Prescot, Chair of the NeuConnect Board and co-founder of lead investor Meridiam: “NeuConnect will create a vital new energy link at a time when sustainable, resilient connections across Europe have never been more important.”

By allowing 1.4 GW of clean electricity to flow in either direction, NeuConnect ensures that when wind production peaks in one market, surplus power is instantly diverted to where demand is highest rather than being wasted. This geographic flexibility does more than just reduce the need for fossil-fuel backups; it turns isolated national grids into a resilient, integrated European “Supergrid.” It is a testament to the fact that a truly sovereign energy system is not one that stands alone, but one that is seamlessly woven together.

Projects like Jänschwalde and NeuConnect show that the fight for a self-reliant Europe has moved into a grittier phase. The focus has shifted to breaking the bottlenecks that stall progress: aging lines that groan under new loads and national grids still locked behind borders. By weaving these markets into a “supergrid,” the continent is finally moving toward a system where green power is shared and stored with industrial precision.

Yet, while wind and solar now do the heavy lifting, they are no longer the only players. A new crop of green technologies is emerging, proving that even in their infancy, these projects hold immense potential when public backing and private grit are paired with professional care. This brings the focus to the new frontier: those “next-gen” renewables only just beginning to find their footing.

Securing ‘firm’ power

Only a decade ago, wind and solar were dismissed as mere side-shows to the heavyweights of oil and gas. Today, they are the bedrock. We are now seeing a similar birth for a fresh generation of power, as the search turns to “firm,” steady energy that can be moved and stored to kill off the last of our fossil fuel habits. This shift is led by a surge in biogases—with biomethane hitting a massive 7 billion cubic metre milestone by late 2025—and a move toward green ammonia and next-gen geothermal heat. Ammonia, in particular, has become a vital vessel for energy, allowing green power to be shipped across oceans to fuel the heavy tankers that once relied on thick bunker oil.

Building this energy “fortress” depends on a tight bond between the state and private firms. The EU offers a sure bet for demand through deals like the €2 billion Circular Bio-based Europe partnership and several others. For their part, companies are no longer just buying power; they are building the plants and wells themselves. By using new tools to blunt the sting of high startup costs, they are turning lab breakthroughs into hard industrial facts. To see how these grand plans work on the ground, one must look to the pioneers out on the frontier.

Eavor: Unlocking the baseload beneath the feet

In Geretsried, Germany, the Canadian-born innovator Eavor has proven that the newest crop of renewables holds as much promise as the wind and solar that came before them. By early 2026, their flagship site began feeding the grid, using a “closed-loop” system that acts like a massive underground radiator. Unlike old geothermal wells that need rare hot springs, this setup harvests the earth’s heat nearly anywhere. It offers a steady, 24/7 baseline of power—8.2 MW of electricity and 64 MW of heat—that does not fade when the wind stops or the sun sets.

The success at Geretsried shows that immense potential can be found in nascent fields when the right hands are at the wheel. By meeting a €91 million grant from the EU Innovation Fund with the grit and professional care of private engineers, Eavor has managed to de-risk the unknown. This project serves as a blueprint for “firm” renewable power, proving that with enough technical discipline and public-private backing, the heat beneath our feet can become a cornerstone of the continent’s energy fortress.

Green North Energy: Securing sovereignty in Naantali

Further north in Naantali, Finland, Green North Energy is proving that sustainability and industrial scale go hand-in-hand. By early 2026, their project to turn Finnish wind into 100,000 tonnes of green ammonia annually moved into its final stages. This is not just about making fuel; it is about energy sovereignty. Ammonia acts as a vital carrier, allowing renewable power to be bottled and moved to heat heavy ships or make fossil-free fertilizer, cutting the cord on imported chemicals and gas.

The realization of this “energy vessel” highlights how professional management can turn a complex tech hurdle into a national asset. Backed by a €600 million investment and the infrastructure expertise of Meridiam, the project shows that the next generation of energy requires a sophisticated triangle of cooperation. It stands as a prime example of how even the newest projects, when approached with due care, can become as vital to the European backbone as the massive wind farms spinning offshore.

A foundation of reliability

Ultimately, the path to a truly sovereign European energy future lies in a wide-reaching, resilient energy mix that finally severs the cord of external dependency. By leveraging the industrial maturity of wind and solar to form a stable backbone, while simultaneously nurturing next-generation breakthroughs—like geothermal heat and green ammonia—with the same intensity that launched the first renewables decades ago, the continent can turn its old vulnerabilities into a strategic edge.

European policymakers have a powerful advantage in this pursuit: they can count on a vanguard of outstanding homegrown companies and projects already doing the heavy lifting. However, the move from blueprint to reality hinges on more than just capital; it requires the steady hand of trusted, professional energy operators who can navigate the gritty technical and regulatory mazes of a modern grid. As Europe enters this new era, the success of these ventures will depend on a high standard of expertise and accountability. By backing these proven champions, the continent ensures its green autonomy is built on a foundation of reliability and long-term excellence.
