The Cleantech-Cluster Upper Austria

The Cleantech-Cluster (CTC) is the platform for energy and environmental technology companies in Upper Austria. It supports innovation, competitiveness and visibility of its partner companies. It contributes to market growth across the value chain in the fields of sustainable energy and environmental technologies.

Together, innovative, environmentally and economically sound solutions for the present and the future are developed and implemented. The cluster serves as an interface between companies, research and training institutions, decision-makers and users. The CTC initiates, promotes and coordinates the cooperation between the more than 250 partner companies.

The Cleantech-Cluster builds upon the experiences and contacts of two successful networks (Ökoenergie-Cluster and Umwelttechnik-Cluster). Two specialised teams - situated at the OÖ Energiesparverband and Business Upper Austria - support the topics of energy and environmental technologies.
