Research and development

• Further development of two-tank storage systems for commercial solar thermal power plants
• Development of an in-fill tank with lower investment costs
• Nitrate salt storage tank with increased operating temperatures > 560 °C

Methods and infrastructure

• Pilot plant TESIS:store for the development of in-bottom storage tanks with liquid salt
• Pilot plant for pre-testing of liquid salt storage concepts up to 700 ° C
• Modelling of heat and material transport, as well as salt chemistry with respect to the gas atmosphere
• Tools for conceptual design and cost estimation of liquid salt storage tanks
