Berlin Battery Hackathon
The Battery Hackathon comes back to Berlin!
Join us and 80+ hackers from across Europe and beyond for the Berlin Battery Hackathon on April 24–26, 2026, in Berlin.
We want to bring together builders from battery technology, energy markets, and energy operations to work on real challenges around storage, grid applications, and intelligent energy management.
Batteries have become strategic infrastructure. They shape grid resilience, renewable integration, and energy security — and this hackathon is meant to turn those challenges into concrete solutions.
You’ll work on challenges from industry partners, get direct feedback from experts, and spend 36 hours building alongside developers, engineers, founders, and energy professionals.
Our goal with the hackathon is to put you in a position to continue towards a real pilot or project.
