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’s fuel cell heating mechanism recovers waste heat from the fuel cell to provide space heating and hot water. The fuel cell operates at 45–55% electrical efficiency, with the remaining energy released as heat. This heat is captured via heat exchangers and used directly in radiators or underfloor heating systems, reducing reliance on conventional boilers. For example, Picea-equipped homes achieve 50% heating cost savings compared to grid-dependent systems. The system’s thermal management also integrates with heat pumps for hybrid heating during extreme cold, ensuring year-round comfort with 100% renewable energy.

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

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.
