("Proton Motor" or the "Company")

Follow-up order from GKN Hydrogen

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, is pleased to announce that it has received a further order from GKN Hydrogen Italy S.r.l. ("GKN Hydrogen") for an additional 15 "HyModule® S8" hydrogen fuel cell systems.

The HyModule® S8 system is an emission-free high-tech product from the Company's Hy-brand portfolio for stationary applications and is designed for the autonomous provision of energy and heat. The Company anticipates that the HyModule® S8 systems will be delivered to GKN Hydrogen in the first nine months of 2023.

GKN Hydrogen is part of GKN, the Aerospace, Automotive and Powder Metallurgy international business controlled by Melrose Industries plc. Taking into account previous orders, GKN Hydrogen has now ordered 46 "HyModule® S8" hydrogen fuel cell systems in total from Proton Motor. While there can be no certainty, the Board of Proton Motor expects to receive further orders as GKN Hydrogen continues to integrate the Company's technology in its "HY2" energy systems.

GKN Hydrogen is deploying the green sustainable power plant "HY2" based on renewable resources in its own facilities and with its customers in the residential, industrial and transportation sectors. Applications of the "HY2" metal hydride storage solution include IT back-up systems, off-grid power generation and plug-in electric car charging station. Further information on GKN's HY2 energy systems can be found at https://www.gknhydrogen.com.

Proton Motor CEO, Dr. Faiz Nahab, commented: "We are delighted to continue to support GKN Hydrogen in their drive to demonstrate the use of hydrogen as a means of storing energy from renewable resources and we look forward to expanding our relationship to support GKN Hydrogen's international sales."
