On May 28, 2024, at the Huaqiang New Energy Clean Energy Integrated Development Demonstration Park in Zhangbei County, Zhangjiakou City, RigorPower unveiled its independently designed and developed "SparkTorch 10K" 10kW Hydrogen Energy Storage Hydrogen Production Combined Heat and Power (CHP) System. Following the release, the system commenced demonstration operation and testing. After successfully achieving off-grid operation, it was upgraded to a 100kW power system. As of March 2025, to meet the park’s actual energy supply demands, the system has accumulated nearly 1,000 hours of safe and stable operation, with an average daily runtime of 5-6 hours, and has exceeded 200 days of cumulative operation.

The hydrogen energy storage combined heat and power (CHP) system consists of subsystems including hydrogen production via water electrolysis, hydrogen storage, fuel cell power generation, heat supply, and safety auxiliaries. Its source end is connected to photovoltaic (PV) power, and through coordinated operation with PV electricity, it provides 24/7 green electricity and energy supply for the zero-carbon town.
During effective PV periods (primarily daytime), PV supplies electricity to the zero-carbon town. A portion of the PV energy is used for hydrogen production via water electrolysis and storage, while waste heat generated during hydrogen production is utilized for heating.
During ineffective PV periods (primarily nighttime), the previously stored hydrogen is converted into electricity via fuel cell power generation to supply the town, with waste heat from power generation also used for heating.
To ensure timeliness and stability of energy supply, the entire project is also equipped with a lithium battery system.
The system operates with full-process visualization, automation, and intelligence, enabling fully automated, unmanned operation with real-time monitoring and inspection during runtime.

In addition to providing basic power supply, the entire system maintains a stable heating temperature above 45°C and automatically detects and adjusts its output power based on users' actual electricity and heating demands, successfully ensuring year-round winter usage requirements. Furthermore, the system features a two-way connection to the grid: it can utilize off-peak electricity for hydrogen production and supply power to designated areas to reduce grid load.

In the next phase, RigorPower will conduct lifespan verification while initiating a new round of operational mode design, product technical validation, and economic feasibility assessments. The focus will be on active research in areas such as:
Efficiency enhancement of fuel cell microgrids,Active grid support,Multi-unit coordination,Hydrogen-electric coupling efficiency,Hydrogen-electric safety.

Furthermore, the 300kW hydrogen power generation system delivered and operating smoothly by RigorPower in Shanghai in 2024 is currently awaiting user notification to upgrade to the Phase II 1MW hydrogen power generation system. Concurrently, RigorPower will deliver the 100 SCM/h hydrogen production system and 3MW hydrogen power plant project contracted in the previous year by 2025. This project will be utilized for green hydrogen energy storage in the power grid.
Looking ahead, RigorPower will deepen industrial integration with Huaqiang Group’s cultural tourism and diversified industrial resource sectors. Together with partners across the hydrogen energy industry, the company will steadily develop more hydrogen application scenarios. In the field of hydrogen energy storage, RigorPower aims to deploy larger-scale, more economically viable hydrogen energy storage power generation projects, effectively enhancing the grid’s flexible regulation capabilities and accelerating the development of a new-type power system that integrates electricity-hydrogen synergy. These efforts will provide innovative technical pathways and solutions for the commercial application of hydrogen energy storage in future renewable energy accommodation networks.
