Students create innovative solutions on Bornholm

Engineering students once again visited Bornholm to develop sustainable solutions that address the island’s challenges and contribute to realizing the climate goals of the regional energy and utility company, BEOF. The initiative highlights how valuable innovation can be created outside major companies in the big cities.

Magnetic power supply cable

In 2022, a ship's anchor destroyed Bornholm's power supply connection from Sweden. This forced the island to produce its own electricity for a period of time—and the repair cost DKK 50 million.

Engineering student Veronica Euan Jensen and her group have developed a solution that reduces the risk of that happening again. The group proposes dividing the cable into modules connected by electromagnets. This way, only the damaged part needs to be replaced. In theory, if a module is only torn loose, it can reconnect itself using the magnetic field:

“Our biggest challenge is probably how to ensure that the magnetic field is strong enough to find and connect the modules, and how we guarantee that the connection is good,” says Veronica Euan Jensen.

Education app

Through discussions with Bornholmske Borgerforeningers Samvirke, an umbrella organization for several local citizens' associations on the island, Martin Merforth and his group discovered that Bornholm is struggling to retain and attract young people - 30% of the island's population is over 65 years old, and many young people leave for the mainland to study.

Martin Marforth's group has developed a simple idea: An education app where young people can get internships at companies on Bornholm that match their field of study. The companies get to know the students—and may choose to hire them afterwards. It is a solution that benefits the students, the companies, and Bornholm.

Local greenhouse heated by waste heat

Rikke Alstrup, a student on the Innovation in Engineering course, has been working with her group to create a green initiative that directly involves the citizens of Bornholm in the green transition. The project involves establishing a local greenhouse which, in collaboration with BEOF, will be heated by waste heat from district heating installations. Local residents will be allocated a piece of land, and there will also be a café where everyone is welcome.

 

To come up with the concept, the group used a method that Rikke Alstrup had not used before:

“We started with 10 ideas. Then we narrowed it down and looked at which idea actually had potential. It taught me a new way of working with idea development and projects,” says Rikke Alstrup.
