Proton Motor Power Systems plc (AIM: PPS), the designer, developer and producer of fuel cells and fuel cell electric hybrid systems with a zero-carbon footprint, announces that it has delivered three of its emission-free high-tech innovation "HyFrame® S36" systems to its new customer, WILO SE ("Wilo").

The Dortmund-based group, Wilo (www.wilo.com), is a leading provider of pumps and pump systems for the building services, water management and industrial sectors.

The modular and universally applicable "HyFrame® S36" systems, supplied by the Company, can generate 36kW of electricity each and will be integrated as components into Wilo's planned "H₂Powerplant". The pilot project will serve as an emergency power plant for Wilo's headquarters "Wilopark" in the south of Dortmund, which was inaugurated in 2021. The state of North Rhine-Westphalia and the city of Dortmund issued the official building permit in the Spring of 2022.

Dr. Nahab, CEO of Proton, commented: "The entire Proton Motor team is very proud of the powerful hydrogen fuel cells we have provided and which provide a decentralised and decarbonised energy supply. We are confident that they will make a decisive contribution to the success of a sustainable energy transition for industrial companies such as Wilo."
