The European Solar Research Infrastructure for Concentrated Solar Power (EU-SOLARIS) is a distributed Research Infrastructure that aims to achieve a real coordination of Research and Technology Development (RTD) capabilities and efforts in Concentrating Solar Power/Solar Thermal Energy (CSP/STE) technologies by the European Research Centres. EU-SOLARIS will become the reference for CSP/STE and maintain Europe at the forefront of these technologies by providing the most complete, high quality scientific portfolio and facilitating the access of researchers to highly specialised facilities via a single access point. EU-SOLARIS will link scientific communities and industry and speed up the development of research and innovation due to a closer collaboration model, knowledge exchange management and a wider dissemination of results. It will increase the efficiency of the economic and human resources required to achieve excellence and provide efficient resources management to complement research and avoid redundancies. EU-SOLARIS was included in the ESFRI Roadmap 2010 and started operations in January 2023. As expressed in its statutes, these are the Mission, Vision and Objectives of EU-SOLARIS ERIC: Vision: To become the European reference research infrastructure in the technological development of CSP/STE and related applications. Mission: To offer the best conditions for the development of CSP/STE research activities for the scientific and industrial communities Strategic objectives are, i) To coordinate, as a unique infrastructure of distributed character the main existing R&D installations in Europe, providing the most complete and high quality scientific infrastructure portfolio at international level to the CSP/STE sector; ii) To establish a single entry point where highly specialised facilities, resources and research services are effectively and optimally offered to users demanding CSP/STE related services; iii) To reinforce the collaboration between the scientific institutions, academia and industry, also fostering collaborative research among main European research centres of the sector; iv) To identify new requirements for the improvement of the research facilities, and for the construction of new ones (when needed), also optimizing and promoting the specialization of existing ones avoiding unnecessary technological duplication and repetition; v) To identify and establish the best research and experimental practices, leading and coordinating the open dissemination of results and experimental data whenever possible, thus contributing to the reinforcement of the European leadership position at an international level; vi) To maintain Europe at the forefront and leadership of CSP/STE technologies development.
