The demonstrator will showcase the combination of existing technologies for use in CCU. Heat is a substantial part of the operating cost, so this interdependency between CO2-separation and heat is an interesting opportunity for the combined system.
Thus, a key design feature in the combined system will be based on the integration between the two, either by driving the separation with waste heat, or recovering waste heat from CO2 separation.
The integration will be applied both to water vapour condensation and to gas separation, whether by absorption or membrane. Once the CCU for the greenhouse is established, the project actors and others can develop other CO2 uses on the same platform.
Opportunities have been identified for algae farming or fuel production. Lastly, because emission sources and sinks will not always be in proximity, the CO2 could be liquified and distributed elsewhere.
Interest of such an arrangement have also already been identified. For all these uses, it is a question of cost. The demonstrator will design, construct and operate a complete system, thus achieving TRL 7.
