**Editor’s Note:** Arezzo’s gold district is pioneering a green revolution in high jewelry with the “Phe4Gold” project, which aims to power production exclusively with green hydrogen. This initiative marks a significant step toward sustainable luxury.
The future of jewelry passes through Arezzo and increasingly speaks the language of sustainability. The Arezzo gold district will become a testing laboratory for a technology destined to change the way high jewelry is produced: the use of green hydrogen as an exclusive energy source. This is the goal of the project “Phe4Gold – Photovoltaic Hydrogen Electrolysis For Gold,” promoted by Graziella Braccialini together with Brt Consulting, which won the Mission Innovation 2.0 tender of the Pnrr.
The project has received funding of approximately two million euros from the Ministry of Environment and Energy Security and was selected among only eleven nationwide. The ambition is to achieve a production system powered 100% by renewable sources, through the integration of photovoltaics, hydrogen production, and storage systems, contributing concretely to the decarbonization of the goldsmith sector.
The role of Brt Consulting, an Arezzo-based company already active internationally, is decisive.
“Phe4Gold” involves four companies along the Arezzo-Pisa axis: in addition to Graziella Braccialini, participants include Arezzo-based G-Smart, Enapter, and Zerynth, with scientific support from the University of Pisa.
