2022 Lorraine

This was the 8th edition of doc-ECE in Lorraine on Entrepreneurship in the Circular Economy

When? 28 November to 2 december, 2022

Where? Saxon-Sinon, Lorraine, France

Europe has launched several major initiatives and an IPCEI to support innovation and rapid development of hydrogen as an energy carrier. Green hydrogen resulting from the conversion of renewable energies is a major component of the green deal strategy.


With our partner John COCKERILL, a world leader in green hydrogen generation, we aim at analyzing the potential for a circular deployment of their new range of alkaline water electrolysers. Note that no previous knowledge on hydrogen technologies is required!


After a brief introduction to the main principles of circular economy, circular design and the raw materials value chain, students will be invited to work in multidisciplinary teams and analyze different scenarios to optimize a repair-reuse-recycle approach for John Cockerill's electrolysers. The whole week includes several seminars, ideation sessions, testimonies and a final pitch competition.


All other activities and accomodations will be hosted by “Le Gîte des Hauts de Sions’ located near Nancy (France).

The objective

The concept

The core of the programme is the intense 5-day winter school from November 28 to December 2. The participants will work in multidisciplinary teams to solve a challenge provided by an industrial partner (John Cockrill) and are coached by our experts.
