TÜV SÜD has certified two H₂ power cubes (HPC) from the Chinese manufacturer COSBER Technology. HPCs are integrated systems for the self-sufficient energy supply of buildings. A total of three certificates confirm the general safety of the devices and their conformity with the European Pressure Equipment and EMC Directives.

COSBER Technology is one of the leading manufacturers of vehicle testing equipment. The company also develops innovative solutions for a sustainable and secure energy supply. With its Smart H₂ Energy Platform, COSBER is presenting an integrated solution for the self-sufficient energy supply of buildings based on H₂. The key components of the platform are the HPC, which include a AEM electrolyzer, a H₂ storage unit, a fuel cell power generation system, a power inverter system and a heat exchange system. In combination with photovoltaic or wind energy systems, HPCs can cover the entire energy requirements of buildings with renewable energy and H₂.

"The certification of HPCs with their various components was a real challenge that we took on with an interdisciplinary team," said Dr Helge Knobbe, Head of Industry Service at TÜV SÜD Korea. The first step was to determine the relevant regulations and then to test the HPCs on the basis of these regulations. For the European market, these are the Machinery Directive 2023/1230, the Pressure Equipment Directive 2024/68/EU and the EMC Directive 2014/30/EU for electromagnetic compatibility. Following successful testing, TÜV SÜD recently handed over the Safety Risk Assessment Reports and the corresponding certificates for the HPC-1000 Plus and HPC-3000 Plus to COSBER.

Dr Helge Knobbe said, "COSBER already took the regulatory requirements into account during the development of the H₂ Energy platform and the HPCs and prepared very specifically for certification in accordance with European standards. This made the complex certification process easier and accelerated the entire process."
