EuroTeQaThon 2026 : L’X wins the European student competition

Organised each year by one of EuroTeQ’s member universities, the EuroTeQaThon brings together multidisciplinary student teams to tackle major socio-environmental challenges, asking them to design innovative solutions in response. The 2026 edition was held from 13 to 15 June at the Technical University of Denmark (DTU) in Copenhagen, under the theme "Enhance Connections for a Sustainable Future". 

Twenty-two teams from partner universities, including two from l'X, presented their projects to a jury of academic and industry experts, following several weeks of collaborative work as part of the EuroTeQ Collider course.

BESSaaS: turning barriers to the energy transition into collective opportunity

The winning team, made up of École polytechnique's Master of Science & Technology (MSc&T) students Florian Kozikowski, Luca Knab and Emily Hommerich, won the jury over with their project "BESSaaS", a solution tackling local electricity grid congestion. The concept: installing battery storage units directly at the points where renewable energy is wasted due to insufficient transmission capacity. What sets the solution apart is also its participatory business model, enabling local communities to invest in these installations and receive dividends in return. The team sums up their project in a single sentence: "We turn wasted energy into community wealth by deploying batteries that citizens co-own."
 

L'X steps onto the EuroTeQaThon winner’s podium for the first time

This win by a student team from École Polytechnique marks a first since the EuroTeQaThon was launched. Florian, Luca, and Emily successfully defended their project before the jury, standing out in an international environment where innovative ideas are in no short supply, and turning technical expertise into an entrepreneurial project with real-world impact. Securing first place also reflects the growing engagement of École Polytechnique students within the EuroTeQ alliance, of which l'X is a founding member.

For the members of the BESSaaS team, the competition was far more than an academic exercise. "The EuroTeQaThon was a truly great experience to explore my entrepreneurial spirit. I really enjoyed working on a project with my friends, completely intrinsically driven and outside of the usual classwork," says one of the team members. 

Beyond the result itself, it is the human and interdisciplinary dimension that makes the event so valuable. Meeting students from vastly different backgrounds, attending workshops dedicated to pitching and inclusivity, and taking part in the activities organised in Copenhagen allowed participants to expand their networks and develop their entrepreneurial thinking in a stimulating environment.

The other winning teams
Two other teams join BESSaaS on the podium in second and third place, alongside a team whose project was recognised with the Audience Award.

• Peak Response (DTU) unlocks the untapped potential of household solar batteries across Europe by connecting them into a coordinated energy pool through a shared network.
• Splitter (TU/e) uses physics-informed machine learning to analyse live sensor data and prevent unpredictable degradation in green hydrogen electrolyzers. By optimising operations and anticipating maintenance needs, the software extends plant lifespans and makes green hydrogen production cheaper and more reliable.
• Parkinsense (TU/e) received the Audience Award for its wearable device enabling continuous monitoring of Parkinson's disease symptoms in daily life.
