Solvay and Sapio have signed a long-term agreement to jointly develop renewable hydrogen production at Solvay’s Rosignano site in Italy—an initiative central to the Hydrogen Valley Rosignano Project and to decarbonizing Solvay’s local peroxide operations.
As part of the collaboration, Sapio will design, build, and operate a 5 MW electrolyzer, while Solvay will install a 10 MW photovoltaic system to power it. When fully operational in mid-2026, the facility is expected to generate up to 756 tonnes of renewable hydrogen per year, enabling up to a 15% reduction in CO₂ emissions from the Rosignano plant. The initiative has secured €16 million in funding from the Tuscany Region under Italy’s National Recovery and Resilience Plan (PNRR).
The green hydrogen produced will be used directly in Solvay’s peroxide manufacturing processes, supporting cleaner production for downstream industries including electronics, water treatment, solar manufacturing, and food safety.
Carlos Silveira, President of Solvay’s Peroxides business, commented:
“Our collaboration with Sapio enhances the sustainability of our global peroxide operations. This project strengthens our commitment to delivering cleaner solutions to essential sectors—from semiconductors to renewable energy.”
Alberto Dossi, President of the Sapio Group and H2IT, added:
“This project marks a meaningful step in advancing Italy’s hydrogen value chain. By connecting industry, research, policy, and communities, we are helping build a sustainable and competitive hydrogen ecosystem.”
Mario Paterlini, CEO of the Sapio Group, stated:
“We are proud to partner with Solvay on a project that demonstrates how industry can actively support both decarbonization and economic growth. At a time of global uncertainty, initiatives like this provide stability and direction for the entire energy transition landscape.”
The project officially entered the construction phase following a groundbreaking ceremony held on November 18, 2025, with representatives from Solvay, Sapio, and national and regional institutions highlighting its strategic importance for Italy’s clean-energy future.
