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.

The Picea sustainable solution, developed by HPS Home Power Solutions, is a pioneering green hydrogen-based energy system for residential and commercial use. It integrates solar panels, AEM electrolyzers, hydrogen storage tanks, and fuel cells to create a self-sufficient energy ecosystem. Key features include: - Year-round energy autonomy: Stores surplus solar energy as hydrogen during summer for winter electricity/heating via fuel cells. - Thermal efficiency: Recovers waste heat from fuel cells to power space heating or domestic hot water, achieving 90% total energy utilization. - Modular scalability: Multiple Picea units can be cascaded to serve multi-family buildings or small industries. This solution addresses Germany’s mandate for 65% renewable heating by 2025, offering carbon-free warmth even in winter.

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.
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.
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.
