SolarPACES Conference 2025

The SolarPACES-conference is a globally recognised conference in the field of concentrating solar thermal energy. It offers space for dialogue and discussion between stakeholders from research, industry and politics in order to develop solutions to existing energy problems.

This year's host country, Spain, currently operates 49 solar power plants and 23 SHIP systems (Solar Heat for Industrial Processes). This makes Spain a global leader in the field of CST systems. After the conference, there will be an opportunity to visit one of the world's largest public research and development centres for CST technologies: the Plataforma Solar de Almería.

The German Aerospace Center (DLR) is one of the sponsors of this event. DLR is represented by the Institute of Solar Research, the Institute of Future Fuels and the Institute of Technical Thermodynamics. They take the opportunity to explore the latest projects and research progress.

The programme offers numerous presentations on current market trends, technology developments and fields of application in concentrating solar thermal energy we look forward to an intensive exchange with you!
