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.

Why choose us?

Diverse electrolyzer technology coverage

We offer alkaline, PEM, and AEM electrolyzers, catering to needs from large-scale industry (alkaline) to renewable integration (PEM) and cost-efficient innovation (AEM).

High-efficiency PEM electrolyzers for renewables

PEM electrolyzers achieve over 80% efficiency, fast response, and high-purity output, perfectly coupling with wind and solar energy for green hydrogen production.

AEM electrolyzers balance cost and efficiency

AEM electrolyzers merge alkaline's cost advantages with PEM's efficiency, using non-precious metal catalysts, suitable for emerging commercial scenarios.

The integrated home unit of Picea combines all critical components—PV inverter, electrolyzer, fuel cell, battery, and hydrogen storage—into a single compact system. Measuring 2.5 m × 1.5 m × 2.0 m, the unit can be installed in basements or utility rooms without major renovations. The Picea 2 model is 70% lighter and shorter than its predecessor, fitting into low-ceiling spaces. The unit includes standardized interfaces for PV connection, heat distribution, and grid synchronization, ensuring plug-and-play installation. All components are optimized for silent operation and require minimal maintenance, making it a turnkey solution for energy-independent homes.

Frequently Asked Questions

What is the efficiency of your PEM electrolyzers?

Our PEM electrolyzers boast an efficiency of over 80%, making them highly efficient for hydrogen production. This high efficiency, combined with fast response times, makes them ideal for integration with renewable energy sources like wind and solar.
Our AEM electrolyzers use anion exchange membranes, combining the cost advantages of alkaline electrolyzers with the high efficiency of PEM electrolyzers. They also utilize non-precious metal catalysts, making them a cost-effective and innovative option in early commercialization.
Yes, our hydrogen storage solutions are designed to operate in various climates, including cold regions. Metal hydride systems and specialized tank designs ensure reliable performance even in low-temperature environments.
Our metal hydride storage systems offer high hydrogen density through chemical reactions with metals such as magnesium, titanium, and zirconium. The maximum capacity varies by model, with options tailored for small-scale applications. For home use, typical models can store enough hydrogen to meet daily electricity and heating needs, while on-vehicle versions support extended vehicle range. All are optimized for compactness and safety, fitting seamlessly into their respective scenarios.

Customer Reviews

Mark Davis

We’ve used Picea for 2 years. Even on cloudy days, stored hydrogen ensures consistent electricity. The heat recovery feature is brilliant—no wasted energy. It’s reduced our energy bills by 60%, and we love being carbon-neutral. Highly recommend for homes in cold climates.

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.
