From 25 to 27 November, the PUSH2HEAT consortium gathered in Fiuggi, Italy, for its General Assembly—a key event to review project progress, align on upcoming milestones, and strengthen the collective effort towards large-scale industrial heat decarbonisation.
A highlight of the assembly was the visit to Cartiere di Guarcino (CdG), the industrial site hosting two PUSH2HEAT demonstrators. CdG is a leading paper mill, producing 50,000 tonnes of paper annually, and like many mills, it relies heavily on steam generated from fossil-fuel boilers for its production processes. This made CdG an ideal setting to showcase PUSH2HEAT’s mission: demonstrating how heat upgrade technologies can replace conventional boilers by generating industrial steam directly from waste heat—achieving both significant efficiency improvements and emissions reductions.
What is the current status of the two demos hosted in CDG?
Two PUSH2HEAT demonstrators are being deployed at the Cartiere di Guarcino site, each showcasing a different technology to recover waste heat and generate industrial steam.DEMO 2’s Absorption Heat Transformer (AHT), manufactured by BS Nova with control support from Factor4Solutions, has already been installed and is currently in the commissioning phase. The system upgrades waste heat recovered from the cogeneration unit and converts it into steam at 6.5 bar(a), demonstrating how industrial waste heat can be effectively reused to support production processes.
Alongside this installation, DEMO 3’s High-Temperature Heat Pump (HTHP) manufactured by Cannon Bono is under construction and scheduled for installation in February 2026. Once operational, the system will recover low-grade heat and upgrade it to produce steam at 6.5 bar(a), offering a low-carbon alternative to conventional fossil-fuel boilers.
