The Netherlands-headed bioenergy technology specialist HoSt Bioenergy Systems has disclosed that it has been selected by Italian biomethane project developer Ringas Srl for the modernization, expansion, and biogas upgrading of three existing biogas power plants in Italy.
Located in Cremona and Alessandria, construction is underway with completion scheduled for June 30, 2026.
The total project scope, the value of which has not been disclosed, includes 20 anaerobic digesters, eight of which will be new builds.
The three projects will have a total capacity of 4,000 Nm3/h of biogas with an end-product of 2,200 Nm3/h of biomethane.
HoSt Bioenergy Systems will supply all digester components, flare, and oxygen generators for the three sites, while Ringas will execute the feedstock systems, piping, and balance-of-plant work.
Each location will also be equipped with biogas upgrading systems, delivered by HoSt’s renewable gas technology arm Bright Renewables, to upgrade biogas into biomethane, contributing to Italy’s growing renewable gas production capacity.
Collaboration built on proven reliability
Founded in mid-2024 by SWEN Impact Fund for Transition 2 (SWIFT 2) and BiogaServizi Srl to advance Italy’s biomethane production, Ringas selected HoSt Bioenergy Systems for its proven technology, reliability, and ability to meet tight project timelines.
Revamping existing biogas plants requires specific know-how and flexibility that we have found in HoSt. HoSt supplies both high-quality, future-proof anaerobic digestion and upgrading solutions, making it the right partner to support Ringas’ ambitious plans, said Marco Cipriani, Co-Founder and CEO of Ringas.
Advancing Italy’s biomethane ambitions
According to HoSt, Italy has become one of Europe’s most dynamic biomethane markets, driven by national incentives and a growing commitment to renewable gas as part of its decarbonization strategy.
Ringas is transforming its existing biogas sites, which currently utilize the produced biogas in a combined heat and power (CHP) system for electricity generation, into modern biomethane facilities.
This ensures long-term operational efficiency and sustainability.
We are proud to partner with Ringas in realizing these strategic biomethane projects. By combining Ringas’ strong local expertise with our advanced biogas and upgrading technologies, we are together contributing to Italy’s renewable gas ambitions and the decarbonization of the energy sector, said Michael Ghezzi, Director HoSt Group France and Italy.
