Electric ferries in Fynshav

Visit Fynshav ferry harbor on the island of Als and step aboard Ellen - the world’s first fully electric ferry at its launch in 2019, a pioneer in sustainable maritime transport. The latest addition, Nerthus, showcases the next generation of green ferry technology with its autonomous docking system and high-capacity batteries. You can also see it recharging in just 20 minutes, in the fully automated onshore charging station, demonstrating how the green transition at sea can look like in practice.

Community-Led Rural Bus

Ensuring effective public transportation in low-density rural areas can be a challenge. Visit one of three villages around Sønderborg taking part in a new project exploring flexible mobility solutions designed to meet local needs. In addition to reducing transport-related emissions, the pilot project addresses rural mobility challenges - helping to strengthen both economic and social sustainability.

Application Development Center for machinery of the future

Construction machinery produces significant emissions and wastes energy. Beyond electrification, the industry is tackling this inefficiency with solutions that improve performance and even support the grid during peak demand. This tour unites a component maker, a green fleet operator, and Scandinavia’s largest developer to show real ways to cut emissions now. See live demos of electric, energy-efficient machinery at a test excavation site and racetrack built to drive sustainable urban construction.

Sønderborg Hospital

Discover how Sønderborg Hospital is leading the way in decarbonized healthcare. In response to the 2022 energy crisis, the hospital’s management decided to replace its gas- and oil-based heating system with a new hydronic heating and cooling system. Moreover, by teaming up with a local district heating utility company, it has started to provide its surplus heat to the community. Explore how these solutions are expected to reduce hospital’s energy purchases by 28,300 MWh annually - cutting costs, supporting local energy needs, and creating a healthier indoor environment for patients and staff.

Social Housing Retrofits

The social housing area Kløver/Hvedemarken showcases how modern technologies can upgrade older buildings to meet today’s challenges - positioning it as a frontrunner in achieving new EU targets to reduce energy consumption in existing buildings by 20% by 2035.Since 2003, the 432 apartments dating back to the 1960s have undergone an ongoing energy renovation to reduce heat consumption, lower energy costs, and improve indoor climate comfort. Listen to the story of how these upgrades led to a remarkable 27% drop in heat consumption - contributing to lower emissions and more affordable living.  

Smart, Energy-Efficient Supermarket

Go behind the scenes of a climate friendly and super-efficient supermarket, using world-class heating and cooling technology. Located just outside Sønderborg, the Coop supermarket is purpose-built for the future; designed to maximize energy efficiency, cut operating costs, and support the local energy grid in order to meet greater energy demands, a growing need for cooling and efficient food storage. Monitor how its advanced heating and cooling system works in real time and discover the business model that makes it all possible.
