Energy systems

The energy transition is an infrastructure problem, not a generation problem. We invest in the systems that make renewables reliable, dispatchable, and economically viable at grid scale.

Thesis

Decarbonisation requires more than solar panels and wind turbines. The fundamental bottleneck is infrastructure: storage, transmission, grid intelligence, and the industrial systems that connect generation to consumption. We focus on companies building the backbone of the next energy system — the unsexy but essential layers where physics, engineering, and software converge.

Where we focus
01

Grid-scale storage

Long-duration and short-duration energy storage technologies including battery systems, compressed air, thermal storage, and novel chemistries.

02

Hydrogen infrastructure

Electrolysis, storage, transport, and end-use systems for green hydrogen across industrial and mobility applications.

03

Grid intelligence

Software and hardware for real-time grid management, demand response, and renewable integration at transmission and distribution levels.

04

Power electronics

Inverters, converters, and power management systems that improve efficiency and reliability across the energy value chain.

Why it matters
  • Public and private investment in grids and flexibility is rising across Europe — execution and integration matter as much as capital.
  • Renewable growth increases the need for storage, forecasting, and dispatch — software and hardware must keep pace.
  • Policy and market design in the EU and Nordics increasingly reward assets that improve stability and utilisation.
  • The hardest problems sit between generation and load: coordination, safety, and economics at system level.
