To promote this dialogue, Connective Cities and the Green Hydrogen Exchange Working Group organised a peer learning event in Mombasa, Kenya, in November a second edition of the first gathering in April 2025 in Naivasha, Kenya.

Since its first edition, the working group network has grown from early vision-sharing to a collaborative platform where local governments, experts, and industry representatives can transform promising ideas into actionable projects.

The group works by mobilising subgroups with similar disciplines, such as production, transport and infrastructure, market stimulation, and working groups for cross-cutting issues.

For the PrAEctiCe project, the Peer Learning Event aligns closely with the goals and methodologies that promote circular economy principles, knowledge exchange, and innovative solutions for sustainable regional development.

In a keynote presentation titled “Sustainable Water Treatment and Reuse Options” by Prof. Jan Hoinkis, Talha Atiye, and Duc Dinh Ngoc from Karlsruhe University of Applied Sciences, Germany. A presentation that shed light on the project, the reuse of treated wastewater and the production of high-quality water for green hydrogen production via electrolysis.

These initiatives also recognise that sustainability transitions must empower smaller and mid-sized entities, which supports the PrAEctiCe project ideology on capacity building and enabling municipalities to design solutions that fit their contexts rather than adopting top-down models.

In a context where many municipalities lack technical expertise, regulatory experience, or access to finance, the Working Group serves as a supportive space for peer learning and capacity building. Its ambition is to ensure that hydrogen investments are not merely export-driven or technology-focused, but rather contribute to inclusive, local value creation.
