The so-called Power-to-Power (P2P) system uses an Enapter-made AEM electrolyser to produce hydrogen from mains water, which is then stored in metal hydride technology from Switzerland’s GRZ Technologies, before conversion back to electricity through a fuel cell.

All integrated within a “cabinet” installed at Layer Electronics’ facility, Simplifhy claims the system provides an “international benchmark” for industrial uninterruptible power supplies.

The system also features an integrated water treatment system that the company says ensures “optimal performance and longevity” of the electrolysers.

Currently designed solely for demonstration, the installation is part of a project engineered by Italian electrical engineer Derec Consulting.

While AEM is seen as a promising technology, it remains nascent compared to PEM and alkaline, with larger-scale commercial deployment limited. Due to the lack of precious metals, there are still challenges related to the technology’s durability.

The process sees hydrogen stored through absorption into a metal alloy, where hydrogen molecules bond with the metal, forming a solid compound instead of being stored as a gas or liquid.

Typically, metal hydrides can hold about 4-8% of their own weight in hydrogen.
