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 RSE / RSV smart meter by Pietro Fiorentini comes from the integration of traditional gas meters with new generation electronic module.
The transmission from the measuring group to the electronic board is carried out by a high-technology interface, made upon an efficient anti-tampering system, supplying the maximum guarantee against any fraud attempt.
The type of gas, its pressure as well as any impurity does not interfere on the performance of this device, mainly used in low pressure gas distribution networks for residential market.
RSE / RSV is Hydrogen Ready for NG-H2 blending.

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 […]
