Blockchain Meets the Grid: Mapping Opportunities for builders exploring real-world energy systems
05-29, 11:00–11:25 (CET), Seed

Germany’s energy transition is complex—and full of untapped potential for new technologies. This talk offers a hands-on orientation for developers and founders: Where are real-world applications working? What’s blocking progress? Based on market research and systems design, we map out opportunities in a sector ready for change.


Germany’s energy transition is one of the most ambitious infrastructure transformations on the planet – and also one of the most complex. While blockchain is often hailed as a key enabler for decentralization and transparency, real-world applications in the energy sector remain fragmented and rare.

In this session, energy analyst Andreas Corusa (Head of AI Innovation at B.A.U.M. Consult) and systems designer Bernd Riedel (Founder of Ellery Studio and Speculative Futures Berlin) join forces to map the current state of blockchain in the energy space. Based on the study “A Market Overview of Blockchain in the Energy Sector” and design research from the energy atlas "Sun, Wind & Wires", we explore where things are stuck, what’s actually working, and how developers and founders can meaningfully plug into the system.

Expect a hands-on orientation into the German energy landscape, lessons learned from pilot projects, and a systems view on where digital infrastructure meets physical flows. This is a talk for anyone who wants to build for the future—but grounded in reality.

Bernd is a designer, entrepreneur, and publicist. As co-founder and Head of Design at Ellery Studio in Berlin, he leads projects at the intersection of science, design, and societal transformation. His work focuses on science communication, futures research, and participatory formats that foster acceptance and engagement in the energy, mobility, and heating transitions.
