The HyModule® S8 system is an emission-free high-tech product from the Company's Hy-brand portfolio for stationary applications and will be integrated by UMSTRO into various projects for use in emergency power and combined heat and power applications.  Of the eighteen systems ordered, two systems of 8.4kW each are intended for the municipal housing company Euskirchener Baugesellschaft mbH, with which UMSTRO is developing a new energy self-sufficient multi-family house. An additional ten units are intended for use as decentralised and decarbonised energy supply solutions and the remaining six systems are to be produced for stock.

In 2021, Proton manufactured a HyModule® S8 system for integration into UMSTRO's innovative energy trailer, formally known as the "Mobile Solar FuelCell Aggregate".

The Company anticipates that the systems will be provided to UMSTRO throughout 2023 and into 2024.
