Based on the results of research projects, we at Cetaqua develop solutions that can be applied in facilities.


We are committed to ensuring that the results of research are put into practise and contribute to the green transition.

To do this, we follow a process that includes an experimental phase, demonstration in a real environment and integration into operators, digital products or a portfolio of services once feasibility and results have been verified.
