Italian startup Hybitat Srl has developed a groundbreaking hydrogen storage solution for residential applications. The system transforms surplus solar energy into stored hydrogen power. This integrated technology offers 100 kWh capacity, suitable for both homes and small commercial buildings.
Innovation in Home Energy Storage
The system marks a major breakthrough in how homeowners can store renewable energy. It combines hydrogen production and storage capabilities in a format specifically designed for residential installation. Converting extra solar power into hydrogen solves a critical challenge in renewable energy storage. This technology allows homeowners to store energy for much longer periods than traditional battery systems.
System Components and Design
The complete solution features two distinct units working together for optimal energy management. The main processing unit contains essential technology for hydrogen production and power generation. It uses advanced AEM electrolyzer technology to produce hydrogen efficiently and reliably. A PEM fuel cell converts stored hydrogen back into usable electricity when needed.
The system connects smoothly with existing solar installations through specialized power management components. A DC/DC converter and inverter system ensure efficient power flow throughout the entire process.

Market Deployment
Hybitat operates as a key subsidiary of the established SIT Group. They have successfully secured their first major installation contract. The project involves a 200 kWh system installation in a historic 18th-century residence. Installation will begin during the first quarter of 2025. This project demonstrates the system’s adaptability to various architectural environments.
Scalable Solutions
Hybitat offers three distinct system configurations to match different energy requirements. The standard residential package includes a single main unit with one storage unit. Larger installations can utilize expanded configurations with additional storage capacity. The system scales effectively for apartment buildings and commercial properties.
Safety and Compliance
The system meets all requirements under the European Machinery Directive for safety standards. This certification confirms its suitability for both residential and commercial energy applications. Every component undergoes rigorous testing to ensure reliable and safe operation. The certification represents a significant milestone for residential hydrogen storage technology.
The development brings hydrogen storage technology closer to mainstream residential energy markets. Hybitat’s innovation helps address growing demands for sustainable energy storage solutions. Their technology offers a practical approach to long-term renewable energy storage.
