An initiative of the Walloon clusters in the water and energy sectors!

The REWAN HUB [Renewable Energy & Water Network] provides access to all the mapping of Walloon and Brussels stakeholders in the renewable energy and water sectors.
In total, REWAN represents more than 850 organisations. Thanks to structured navigation, it is easy to identify and contact an organisation.
REWAN’s ambition is to contribute to the development of renewable energies and to address the environmental challenges of the water sector, both by acting on supply and on demand.
Our multidisciplinary team will support you through the many challenges of the energy transition and the water sector.
Since their creation, Cluster H2O and Cluster TWEED have each had their own website serving as a communication platform for paying members – that is, water and energy professionals in Wallonia and Brussels. Over time and following feedback from the field, it became evident that an additional component needed to be added to our setup in order to contribute more broadly to the environmental transition and to meet the expectations of stakeholders seeking sustainable solutions.
