Why Digital Supply Security Is Now Part of Energy Cluster Denmark's Strategy

By Glenda Napier, CEO of Energy Cluster Denmark, and Lars Bonderup Bjørn, CEO of EWII and board member of Energy Cluster Denmark.

It’s a bit like the electricity grid at home: you only realize how dependent you are on it when the power goes out. The same is true for digitalization and cybersecurity in the energy system. It’s invisible when it works, but catastrophic when it fails.

So when Energy Cluster Denmark has now made digitalization and cyber- and supply security a dedicated pillar of its strategy, it’s not just a neat bullet point on a PowerPoint slide. It’s a real shift in how we must develop the energy system.

The reason is simple: without digitalization, the green transition will not succeed. And without security in the digital domain, we cannot maintain the supply security that is the very foundation of our society.

We are in a new reality. The Colonial Pipeline in the U.S. was crippled by a cyberattack. Ukraine’s power supply has been the target of repeated digital sabotage. Vestas and Maersk have felt the consequences of cybercrime firsthand. These are reminders that energy infrastructure is a geopolitical target.

At the same time, EU legislation is tightening: the NIS2 and CER directives make cybersecurity a leadership responsibility and a competitive parameter. New requirements for boards and executive management are making their way into Danish companies. This is good and necessary—but also complex and resource-intensive.

Digitalization Is Not Just Software

There is often a perception that digitalization in the energy sector is just about adding a gadget to a wind turbine or rolling out a software tool. But digitalization is not a tool—it is a new way of doing business and developing the energy system.

Used correctly, digitalization can be an alternative to physical expansion: when we can shift and manage consumption over time, we make far better use of existing grids and assets.
When we extract insights from data, we can reduce waste, improve uptime, and postpone major investments in cables and excavators.

It’s cheaper, greener, and smarter. But it requires that we integrate security from the start. Because the more we digitalize, the more exposed we become—unless we protect the systems.

Denmark as a Digital Front-Runner

Fortunately, Denmark has a unique strength: we already have a data foundation most other countries envy. With remotely read meters and a strong digital infrastructure, we have the opportunity to create solutions that could turn into global export successes.

We are also a trust-based society, where citizens and companies are generally more willing to allow data to be shared and used—when it happens under the right conditions. That gives us an edge. But it requires that we don’t rest on our laurels.

Right now, our own success is challenging us: we’ve become so good at building wind turbines, solar parks, and district heating systems that we risk forgetting that future competitiveness will also depend on the digital track.

What Needs to Happen?

First and foremost, focus. We need the first digital companies in the energy sector to succeed and prove that it is possible to create value from data. We need more entrepreneurs who dare to build new solutions on top of the data platforms we already have in Denmark.

We need a skills boost. Companies and educational institutions alike must integrate digitalization and cybersecurity as core competencies to support even more innovation.

Here, Energy Cluster Denmark plays an important role: to push innovation forward and bring together industry, SMEs, and knowledge institutions in new innovation projects, where digitalization and security are not afterthoughts but fundamental premises.

We are already doing this in several of the cluster’s innovation projects and through the Digital Energy Hub (DEH 2.0), which kicks off in September. Together with partners Center Denmark and DigitalLead, we will test practical digital solutions in collaboration with a number of companies and researchers. In DEH, the focus is not only on digitalization but also on supply and cybersecurity, because robust digital energy solutions are essential for a secure energy system. The partnership is supported by the Danish Industry Foundation.

Several current innovation projects also focus on digitalization and security. The RACE project, for example, is developing a digital twin of the district heating system to optimize operations, reduce waste, and thus increase supply security. And HeatSync demonstrates how advanced data management and automation can create a more flexible and robust district heating system.

Two Sides of the Same Coin

Digitalization and supply security are not two parallel tracks, they are two sides of the same coin. We can only succeed with both if we create an energy system that is green, reliable, and competitive.

We can build as many wind turbines and solar parks as we want—but if we cannot manage and protect the system, the risks to our energy system are too great. Conversely, we can build world-class security, but without digitalization, we won’t fully reap the benefits of green energy.

That’s why we say: it’s not only about building big and green. It’s about building smart, digital, and secure. And that is exactly where Denmark has every opportunity to lead the way.

The Danish startup Gridturn, which extends the life of used electric car batteries by converting them into certified battery energy storage systems (BESS), has been awarded EUR 75,000 in support from the Women TechEU program.

The support is given to female-led European technology companies with the potential to deliver significant innovation and sustainable transformation – and it is precisely this combination that makes Gridturn CEO Louise Witt Sengeløv happy:

"There is definitely no queue for the ladies' room when you go to energy-related conferences! There are few women in tech, but it is just a barrier that is extra motivating to break through. The support is a nice recognition and very inspiring for further work," she says.

Challenging the status quo

Gridturn's solution reduces waste and the need for new materials. This is what is needed:

"40 percent of the world's conflicts since the 1960s are related to the fight for raw materials. 90 percent of our biodiversity loss is related to raw material extraction, and we recycle far too little. In Europe we are at 12 percent circularity, in Denmark we are down to 4%. We must succeed in changing that," she says:

"At the same time, it is important that we make it economically sustainable. And yes, it may be difficult, but we have to do better and challenge the status quo," she says.

Gridturn's solution is to extend the life of electric car batteries so that they also have value when they are no longer suitable for electric cars:

"The range is crucial for a car battery, and therefore a reduction to 80 or 85 percent capacity effectively helps to retire the battery. But even with 80 percent capacity, the battery can still function and bring value if you place it in a different context. The batteries will do very well in our system. The ideal senior life," she says.

From waste to infrastructure

Gridturn recycles the batteries into battery energy storage systems (BESS), which integrate with existing energy solutions and help optimize consumption and balance the electricity grid.

This results in significant CO₂ savings, and the circularity is optimal: waste is turned into energy infrastructure.

Gridturn is now entering the market with a certified and scalable product line. A significant development for a startup that has been part of the Beyond Beta accelerator course in Energy Cluster Denmark.

“We hold the key to Europe’s future energy independence. By recycling batteries, we create a solution that is both greener, integrable and economically sustainable. I also hope that our journey can inspire more women to start deep tech companies – my two daughters are a big part of the motivation to lead this development,” says Louise Witt Sengeløv.

In addition to the funding, Gridturn will have access to a European mentoring and acceleration program that will strengthen business, technology and scaling.

In order to examine the condition of wind turbine blades, inspections of blade damages are usually carried out when the turbine has been stopped. In the AQUADA-GO project, the partners have developed a drone technology for automated, contact-free, real-time blade damage detection, while the turbine is spinning. Inspections that are done without stopping the turbine’s normal operation can help save turbine downtime. Now, for the first time ever, the operational concept has been successfully demonstrated offshore.

“We have proven that it is possible to autonomously inspect offshore wind turbines with a drone of a certain size equipped with a visual camera, while the turbine is in operation. This is a major accomplishment for us. We have worked on everything from developing drone software and hardware to mission planning and online data infrastructure. Now, we have a commercially ready solution that can be tailored to wind farm operators’ needs and make inspections easier, faster and more cost-effective,” says Jesper Smit, CEO, Quali Drone.

Drone-based blade inspection delivers significant savings

The core idea of the project is to combine drone technology with thermography and computer vision, enabling detection of surface damage and potential subsurface fractures on operational offshore wind turbine blades. This saves wind farm operators considerable costs due to increased efficiency, while also reducing CO₂ emissions and improving inspection safety.

The new technology has been successfully demonstrated several times onshore by the project partners, which, in addition to Quali Drone and RWE, include Statkraft, TotalEnergies, DTU and Energy Cluster Denmark. Most recently, the solution has been demonstrated offshore with visual drone footage of blade damage on the surface at Rødsand 2 Offshore Wind Farm, operated by RWE since 2010 and located south off the coast of Lolland, Denmark.

“For the first time, we have successfully carried out a drone inspection of offshore wind turbines in operation. This is good news for the entire wind industry. Through the technology developed in AQUADA-GO, we can see the potential of monitoring blade conditions without stopping the offshore turbine. This could help to increase efficiency in our production of green electricity and to further improve safety for our employees. By using drones for autonomous inspections, we expect that downtimes and costs can be significantly reduced in the long run,” says Marcus Mejborn, General Manager of Rødsand 2 Offshore Wind Farm, RWE.

AQUADA-GO technology and AI model show great potential

The project is based on the AQUADA technology developed in DTU Wind Energy’s laboratory. DTU has developed an AI model that helps the drone automatically identify wind turbine blade abnormalities to indicate critical damage using AI algorithms and infrared imaging. The AI model, which is trained and improved with new inspection data each time the drone is deployed at wind farms, shows great potential.

“We have developed an AI model that uses deep learning algorithms and computer-vision technology based on thermomechanical models to assist the drone in detecting blade defects – both on the blade surface and below it. We have tested the technology multiple times at onshore wind farms operated by DTU, RWE and Statkraft, and each campaign has fed the AI model with new data that has made it better. We are very pleased with the results and see great potential for future implementation within the wind industry,” says Xiao CHEN, Associate Professor and Head of Section, DTU Wind and Energy Systems, and Project Technical Lead in AQUADA-GO.

Facts about the project

The AQUADA-GO innovation project runs from 2022 to March 2026 with a total budget of DKK 17,796,010 and is supported by EUDP – the Energy Technology Development and Demonstration Program. The project partners include Quali Drone, the Technical University of Denmark, RWE, Statkraft, TotalEnergies and Energy Cluster Denmark.

Scaling up wind energy, thermal storage, cybersecurity, and pyrolysis.

These are just some of the themes found in Energy Cluster Denmark’s newly published Innovation Roadmap 2026–2027.

The publication contains thematic recommendations from the energy sector’s industry associations and knowledge institutions on what the Danish energy cluster’s innovation projects should address over the next two years across the entire energy system.

One of the contributors is Danish Alliance for Renewables:

“Europe has a strong position in wind technology, which is under heavy pressure from countries that are investing massively to challenge European competitiveness. If we are not to lose our industrial production once again, as we did with solar cells, it is crucial that we prioritize our innovation efforts within wind energy and its integration into our energy system. There is a misconception that wind energy technology is fully developed, but our research environments and industry have shown that there is still enormous potential to increase efficiency, optimize and automate production, ensure physical and cybersecurity, enhance sustainability, and add intelligence to deliver some of the system services that power plants provide today,” says Kasper Roed Jensen, Chairman of Danish Alliance for Renewables, which contributes recommendations through Green Power Denmark.

“The key to the most efficient, secure, and robust energy system lies in research and development in system integration and the interaction between technologies to create the sustainable energy system of the future for the benefit of all,” says Kasper Roed Jensen.

Three areas within storage and conversion
Contributors from the energy cluster to the new Innovation Roadmap include Green Power Denmark, DI Energi, Biogas Danmark, Synergi, Dansk Fjernvarme, Brintbranchen, Dansk Offshore, and the Danish Center for Energy Storage (DaCES).

The latter brings together knowledge institutions and research-oriented companies around a strategic effort in energy storage and conversion, and according to DaCES there are three areas that should be prioritized now:

“High-temperature thermal storage is the key to making industrial electrification both flexible and cost-effective. This requires investments in demonstrators, materials research, and the development of specialized components so that the technology can be scaled and integrated into industry,” says Anne Marie Damgaard, Director of the Danish Center for Energy Storage.

“In addition, active battery components such as battery management systems (BMS) and power conversion systems (PCS) are crucial for safe BESS facilities in the EU and strengthen competitiveness across the entire battery value chain. Finally, our long-term, strategic research initiatives, including innovation missions such as MissionGreenFuels, are important, as these missions play a central role in developing technologies for green fuels and chemicals for sectors that are difficult to decarbonize,” says Anne Marie Damgaard.

Sector coupling and innovation
A third contributor to the energy cluster’s Innovation Roadmap is Biogas Danmark, which sees sector coupling and innovation as the key to a shared green energy system that both drives the green transition and strengthens energy supply security:

“The interaction between biogas and other green technologies, the development of value chains for biogenic CO₂ for carbon storage, as well as future green fuels and materials, are crucial—at the same time, AI can support and accelerate regulatory processes for the expansion of renewable energy,” says Lars Kaspersen, Director of Biogas Danmark.
