Picea: Our Integrated Home Energy System for Self-Sufficiency

We offer the Picea series, such as Picea 2, an all-in-one energy system integrating electrolyzer, hydrogen storage, and fuel cell. It uses photovoltaic power to produce and store hydrogen, and in winter, the fuel cell generates electricity and heat, enabling households to achieve energy self-sufficiency.

Picea ensures reliable winter energy supply by storing surplus solar energy as hydrogen during summer. When sunlight is scarce, the stored hydrogen is fed into a fuel cell to generate electricity for heating (via heat pumps) and domestic use. The system’s waste heat recovery captures up to 90% of energy from fuel cell operation, directly heating water or space. In cold months, Picea can cover 100% of a home’s electricity and 50% of heating needs, reducing reliance on fossil fuels and mitigating winter energy price spikes. This aligns with Germany’s 2025 mandate requiring 65% renewable heating in new buildings.

Customer Reviews

Emma Thompson

The Picea 2 system integrated perfectly with our solar panels. It produces and stores hydrogen efficiently, and in winter, the fuel cell keeps our home warm and powered without relying on the grid. Installation was smooth, and maintenance is minimal. A game-changer for eco-conscious households.

James Wilson

Our Picea system syncs flawlessly with solar. Excess daytime energy becomes hydrogen, which powers us at night. Winter heating is consistent, no more cold spells. Customer support was great during setup—they walked us through every step.
