focused on “unlocking the potential of industrial waste heat and its transformation into electricity via sCO2
of an EU “first-of-its kind sCO2
cycles”, with design and demonstration plant in a real
industrial environment”, namely in a CEMEX cement plant in Prachovice, Czech Republic. This facility has significant untapped waste heat potential, which is currently not exploited and rejected by means of water-cooling towers. The envisaged 2 MW CO2

block will be able to cover about 10% of the site’s electricity needs, amounting to 750 000 € savings per year, thus promising a short payback period (4-8 years).
Project duration June 2021 to May 2025, budget 18.8 million euro, with 14 million euro coming from Horizon.

The project will include development and demonstration of a 2 MW power cycle based on CO2
blends, to be located in Saudi Arabia. The new technology will be tested for one year at an existing CSP plant, that at King Saud University, Riyadh.

The CO2 cycle, as well as reduced
power block specific costs with respect to both conventional steam cycle and pure sCO2
cycle.
The desalination system is a novel combination of direct osmosis and membrane distillation. Forward osmosis (osmotic pressure) induces a flow of seawater through a membrane that will only let freshwater through, but will block salt. Using waste heat from the CSP plant, the diluted solution is heated until the fresh water can be recovered through a second membrane.
Main project goals are the identification of the
