Sirius project completed: green hydrogen electrolyser validated at industrial scale with record purity
Hyter and its partners validated an AEMWE electrolyser up to 1 MW in an industrial environment, achieving hydrogen purity up to 99.999%.

The HM-iCON is a smart meter with hybrid technology for commercial and light-industrial applications.
The HM gas meters series are designed and manufactured to meet the most stringent requirements of the European Natural Gas Distribution industry.
The HM-iCON combines new generation electronical features with a diaphragm measuring unit. The mechanical register is now replaced by an electronic totalizer equipped with a data transmission interface and a remote firmware update function. The HM-iCON combines integrated temperature and pressure sensors that can be used (by configuration) in order to perform gas volume compensation (this feature is only configurable in factory) of the measured gas volume.

Pietro Fiorentini, Athena, 2RZ, the Department of Chemical Sciences of the University of Padua and UniSMART Foundation have joined forces in the Veneto Region-funded LEONE project — LEan Optimisation of Novel Electrolysers. Over 30 months, the partners will work to simplify electrolyser manufacturing, improve reliability and reduce dependence on critical and costly materials. The project […]
2025 was marked by evolving geopolitical dynamics and shifting international balances. In this complex scenario, the solidity of the Pietro Fiorentini Group ensured the continuity needed to face challenges and seize opportunities responsibly and with a long-term vision. Built on this resilience and the Group’s new governance structure, the 2025 Sustainability Report is titled “Many […]
