Investing in energy transition
We build energy sovereignty
and resilience for Europe
First pan-European VC backing energy breakthroughs in New Nuclear, Energy Storage and Energy Efficiency & AI,
innovation for a clean, secure and affordable system.
Mission
Scale Europe's most critical energy breakthroughs, and close the gap between climate targets and industrial deployment
Fossil fuels still cover +80% of energy use. Incremental solutions will not get Europe to net zero. We deploy capital into three complementary pillars: New Nuclear, Energy Storage, and Energy Efficiency & AI.
Conviction
Only energy breakthroughs will deliver the climate neutrality called for by the Paris Agreement. Our job is to find those innovations, and help the most promising reach the world.

Our investment criteria
Team
We evaluate founders on credibility, cohesion and industrial execution: entrepreneurs who can take energy innovation from lab to plant.
Technology
Every file is reviewed through a scientific and economic lens: physics, sustainability, IP, and whether the solution can actually be built at scale.
Market
We back commercially and industrially viable paths, not demos. Go-to-market, offtake, regulation and European industrial partners are part of the underwrite.

Insights
Why we invested, and what we publish
Energy Storage
Why we backed Sinergy Flow
Zinc-sulfur redox flow for long-duration storage: power and energy scaled independently, without critical minerals.
New Nuclear
Why we backed Blue Capsule
Industrial heat up to 750°C without a water source: a Na/Air exchanger built for hydrogen, cement and hard-to-abate heat.
