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).

Mature and stable alkaline electrolyzers

Our alkaline electrolyzers with KOH electrolyte feature mature technology, high operational stability, and low water purity requirements, ideal for large-scale industrial 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.

While Picea is primarily designed for standalone home use, its modular architecture supports microgrid integration in multi-building complexes or community-scale projects. For instance, cascaded Picea units (e.g., 9 units in Bad Kissingen) can supply energy to multi-family buildings with 13,500 kWh storage capacity, balancing local energy supply and demand. The system’s standardized interfaces and grid-synchronous power electronics enable seamless connection to decentralized grids, enhancing resilience and reducing strain on centralized infrastructure.

Frequently Asked Questions

Are your alkaline electrolyzers suitable for areas with low water quality?

Yes, our alkaline electrolyzers have low requirements for feedwater purity. This makes them well-suited for areas with lower water quality, reducing the need for extensive water treatment and lowering overall operational costs.
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.
Our fuel cells, especially PEMFCs, are designed for durability. With proper maintenance, they can have a long operational lifespan, suitable for continuous use in various applications such as transportation and distributed power generation.
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.

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.

Sophie Martinez

I was worried about space, but Picea fits neatly in our garage. It’s quiet, user-friendly, and the app monitoring makes it easy to track hydrogen production. During power outages, it kept our essentials running. Worth every penny for energy security.
