The second edition of the EuroTeQaThon international competition took place at the Technical University of Munich from 23 to 25 November. The best student work from the Collider project course, which is run under the umbrella of the EuroTeQ alliance, made it to this final round. The Alliance brings together top technical universities: Technical University of Munich, Technical University of Denmark, Technical University of Eindhoven, École Polytechnique, Tallinn University of Technology, CTU in Prague, École polytechnique fédérale de Lausanne and Technion Israel Institute of Technology. The challenge itself came from EuroTeQ's industrial partners, and the proposed themes were linked to the "Leave no Waste Behind" challenge. GasNet launched the "Optimisation of power production at gas pressure reduction facilities". The winner in this category was a team of students from CTU who developed the topic "A New Life for Waste Heat". The students from the Faculty of Mechanical Engineering and the Faculty of Nuclear and Physical Engineering will present their solutions on 19 and 20 January 2023 at the European Commission in Brussels.

The students Prokop Pučejdl, Edoardo Tasini (Faculty of Mechanical Engineering) and Danila Lisitskii (Faculty of Nuclear and Physical Engineering) have proposed to optimise electricity production in natural gas pressure reduction stations by using an innovative cycle in which waste heat from the cogeneration units (also known as CHP- combined heat and power units) is used to generate electricity.

The team leader, Prokop Pučejdl, commented on the solution: "Our cycle uses an organic substance as the working medium instead of conventional steam cycles. Because of this, we can use waste heat to generate electricity and make full use of the energy production capacity of the reduction stations throughout the year." He further adds: "The Munich competition brought together a multidisciplinary and multicultural group of competitors and mentors. Therefore, we had a lot of room and opportunities to learn both during the school program and while socializing over the (in Munich so popular) Czech national drink. We entered the final competition, along with two other Czech teams, with the highest ambition, but also with a healthy dose of nervousness. In the end, we were the winners, but to be fair, the credit goes to all three Czech projects."

The project leader of the EuroTeQ Collider course is Prof. Henri Achten from the Faculty of Architecture. He remarks on the success of the CTU students: "I am very happy for our students to have succeeded in this project course, which is not quite common for us. The so-called "Challenge Based Learning" (CBL) at technical universities is a meaningful way of linking assignments from industrial partners and innovative teaching, focusing on current societal challenges."

Thomas Merker, GasNet's CFO, added his message for the winners: "Congratulations to the CTU team on their significant success, which is a great example of the link between higher education and practice. The European gas industry is undergoing a transformation towards renewable energy. GasNet is ready to increase the share of biomethane and hydrogen in the distribution network and implement new technologies similar to the one proposed by the CTU team. Collaboration with schools will be crucial for the green gas industry, and CTU's results in this year's EuroTeQaThon competition are an inspiring example for the future."
