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%.

Direct-operated relief valve, VS/AM 65 by Pietro Fiorentini is a safety device which vents gas when the system pressure exceeds the set value due to temporary events, such as expansion due to rise in gas temperature or downstream pressure shocks caused by sudden changes of flow rate.
Strongly recommended for medium and low pressure gas distribution networks, this device can be used with natural gas and previously filtered non-corrosive gases.

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 […]
