Czech Republic: Mexico-based Cemex plans to install a 2MW waste heat recovery (WHR) plant using supercritical CO₂ (sCO₂) at its Prachovice cement plant. The unit is intended to provide up to 8% of the plant’s electricity requirements.

The producer is part of a consortium studying new sCO₂ WHR systems. The EU Horizon 2020 Industrial Heat to Power fund awarded Euro14m in financial backing to the consortium. The project is intended to demonstrate a cheaper and more flexible method of waste heat valorisation compared to the steam or organic rankine cycle approaches conventionally used in WHR.

Plant director Karol Czubara said, “The new sCO₂ technology has a smaller footprint and higher operational flexibility than conventional power plant cycles, which produce power from turbines using water or steam.”
