As part of the CLEANHYPRO project where PNO Portugal leads WP4, we are thrilled to launch the first wave of open calls, inviting innovative companies, especially SMEs and start-ups, from EU Member States and Horizon Europe-associated countries to accelerate their technology development in the green hydrogen sector. Through these open calls you’ll gain access to fully supported technical and non-technical services designed to bring advanced electrolysis materials and components closer to market. You will benefit from: 

access to 9 state-of-the-art pilot lines across different electrolyser technologies  
expert technical support covering the value chain - from material selection to certification 
business support including market insights, coaching, and investor access to help scale your innovation 
a unique multi-material, multi-technology approach covering four main electrolysis routes and various cell geometries.  

Key dates for this first wave:  Opening: 4 November 2025 Closing: 18 December 2025
