1 Fakulteit Ingenieurswese  Faculty of Engineering Eskom Chair of CSP at Stellenbosch University Prof. Dr.-Ing. Frank Dinter 27 August 2013

2 Existing knowledge on Solar Thermal Energy Prof. Dr.-Eng. Frank Dinter since June 2013 in STERG Former Technical Director of Andasol 3, Spain and Head of Solar at RWE Innogy, Germany 2 Andasol 3: Facts & Figures  Owner: Marquesado Solar S.L. Location: Aldeire/La Calahorra (Granada, Spain)  Capacity: 50 MW el Forecasted electricity production: ~200 GWh/a  Commissioning in autumn 2011 Annual CO 2 savings: 150,000 tonnes  Size of the collector area: ~ 500,000 m²  Technology: Parabolic trough incl. 7.5h molten salt storage

3 3 Source: DLR The main advantage of CSP technology against other RES as PV or wind power is the capability to provide dispatch-able power by storing solar energy through thermal energy storage Flexible and predictable electricity generation Dispatch-able Energy Existing knowledge on Solar Thermal Energy

8 8 STERG Group at SU  A good base with own labs  Moving forward by improving methods and understanding the technology more deeply  Growing networking in SA and worldwide (SASTELA, SASEC, SolarPACES, DLR, Sandia, NREL, etc.)  Reducing costs, increasing efficiency and reliability in CSP technology  Strengthening our relationship to CSIR  Joining and enabling other SA universities in doing more CSP R&D  Supporting national solar R&D plans (roadmaps and centres)  Contract R&D for clients and commercialization Strategic activities at STERG

9 9 Specific technology focus on:  Central Receiver Systems with different Heat Transfer Fluids (e.g. liquid salt, liquid metals and air)  Parabolic Trough and Fresnel with liquid salt  Thermal Energy Storage Systems with different HTF  Component development in Solar fields (Heliostats and Trough)  Optimization on Balance of Plant (Equipment and Process)  Technical and economical evaluation of CSP technologies Potential future strategic focus areas

10 10 View to the world:  SA is one of the best sun spots in the world  Current situation in Europe and US gives SA a chance to catch up  CSP can deliver dispatch-able energy and support SA electricity production reliably  Creating new jobs for new talents for a CSP rollout in SA and worldwide  CSP awareness is improving in government Outlook
