Solvay and Sapio Sign 10-Year Deal for Renewable Hydrogen Production at Rosignano, Backed by Italy’s PNRR

Solvay and Sapio have signed a 10-year agreement to develop renewable hydrogen production at Solvay’s Rosignano site in Italy, a key component of the Hydrogen Valley Rosignano Project aimed at cutting emissions from the company’s peroxide operations.

Under the partnership, Sapio will build and operate a 5 MW electrolysis plant, while Solvay will install a 10 MW solar photovoltaic system to power the facility. Scheduled to begin operations by mid-2026, the integrated project is expected to produce up to 756 tonnes of renewable hydrogen per year, enabling a 15% reduction in CO₂ emissions at the site. 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 supply Solvay’s peroxide manufacturing operations, which serve multiple industries, including electronics, solar panel production, water treatment, energy, and food safety.

Carlos Silveira, President of Solvay Peroxides, said the collaboration strengthens the company’s global peroxide operations and aligns with its strategy to provide more sustainable solutions to key industrial sectors.

Sapio Group President Alberto Dossi said the project represents a major step forward for Italy’s hydrogen value chain, emphasizing the importance of collaboration among industry, research institutions, policymakers, and communities. Sapio CEO Mario Paterlini added that the project demonstrates how companies can meaningfully contribute to decarbonization and national growth.

The project’s construction phase officially began with a groundbreaking ceremony on 18 November 2025, attended by Solvay and Sapio leadership and representatives from national, regional, and local authorities. The event highlighted the project’s strategic role in advancing Italy’s clean-energy transition.
