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.

Picea delivers energy autonomy by combining short-term battery storage (25 kWh) with long-term hydrogen storage (1,500 kWh). Excess solar energy is stored as hydrogen during summer, which is converted back to electricity and heat in winter. The system’s predictive energy management optimizes energy flows, ensuring self-sufficiency even during extended periods of low solar irradiation. With over 100 times the storage capacity of conventional home batteries, Picea enables households to meet 100% of their energy needs without grid reliance. The Picea app allows users to monitor real-time energy usage and adjust settings for maximum autonomy, including reserving hydrogen for emergencies.

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.
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.
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

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.
