Tuesday: Energy Sprint

5 December 2023, ETH Zurich


What is the Energy Sprint?

During the Energy Sprint, participants explored the not-yet-solved problems on a path towards a more sustainable energy system. They have been guided through a Design Thinking Process to come up with creative ideas and a concept to tackle the challenges ahead of us all.

Our energy experts from industry and research provided the participants with insights into the current challenges of the innovation fields in the energy sector: electricity supply + policy, mobility, built environment, storage + grids.

The mix of people from different backgrounds, the opportunity to be creative or even a little bit crazy and the relevance of the topic turned this event into an unique experience. In only one day,  students understood an industry challenge, formed teams, defined a relevant problem and upon this developped, prototyped and pitched a solution.


Who was participating?

The Energy Sprint is an event that is aimed at Masters and Doctoral students. The selection of the participants was very competitive and has been made by an expert jury. The Energy Sprint was performed in English.


What were the prizes for the best pitches?

In addition to the gained experience and the support you received from the facilitators and the energy experts during the day, the winning team of the jury prize received CHF 3’000 in the form of the “ESC Start-Up Ticket” – provided that they participate in the Venture Kick.

Wednesday: Next Generation University

6. December 2023, ETH Zurich


What is the Next Generation University about?

As part of the Energy Week @ ETH 2023, a new sub-event has been launched this year, the “Next Generation University”, which addressed to interested students (1-2 years before Swiss Matura or “Berufsmatura”). At the “Next Generation University” students worked in teams to develop creative solutions for very specific energy challenges. The focus was on the following areas: electricity supply + policy, mobility, built environment, storage + grids.
A “Challenge” was defined for each topic, and the solution process has been accompanied during the day by energy experts and a professional design thinking team. The teams were interdisciplinary and focuses in particular on the development of creative solutions.


Who could participate?

Enthusiastic students (entire classes are welcome as well), especially two years prior to the Matura.


Was there a prize to be won?

The winners of the best solution of the day goz the chance for a coaching session (duration of three hours ) from ETH energy experts for their Matura thesis.



Registration for entire classes is not possible any more. Individual students interested in energy in the last two school years before the Matura can gain information aboit the event via

Wednesday: DemoUpCARMA Closing Event

6 December 2023, ETH Zurich

Specific solutions for CO2 management – Lessons learned from the DemoUpCARMA research project

At this half-day event, the main findings of the pilot project DemoUpCARMA were presented. It investigated the implementation and scale-up of two pathways leading to negative emissions: CO2 utilization and permanent storage in concrete in Switzerland using a novel technology and CO2 transport and permanent storage in a geological reservoir abroad.

The event has been held in English and was part of a collaboration between the Energy Science Center and the DemoUpCARMA management team.
