  1. Eskom Chair of CSP at Stellenbosch University Prof. Dr.-Ing. Frank Dinter 27 August 2013

  2. 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 Existing knowledge on Solar Thermal Energy Andasol 3: Facts & Figures • Owner: Marquesado Solar S.L. Location: Aldeire/La Calahorra (Granada, Spain) • Capacity: 50 MWelForecasted electricity production: ~200 GWh/a • Commissioning in autumn 2011 Annual CO2 savings: 150,000 tonnes • Size of the collector area: ~ 500,000 m² • Technology: Parabolic trough incl. 7.5h molten salt storage

  3. Existing knowledge on Solar Thermal Energy Dispatch-able Energy 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 Source: DLR

  4. Solar thermal history at SU First Parabolic Trough Research Research and academic committee representative SANERI/DST Solar thermal spoke & Hope project SOLAR THERMAL ENERGY RESEARCH GROUP National SANERI/DST RE centre founded Solar roof lab commissioned Dry cooling research at SU commences Sasol researcher Solar chimney research at SU commences Solar resource station at SU

  5. STERG acceleration Eskom chair and centre of excellence NRF solar thermal spoke 2013 - 17 SOLAR THERMAL ENERGY RESEARCH GROUP Sasol 40 m2 heliostat field Solar roof lab expansion (with tower, kiln, etc) Solar resource station at SU

  6. Staff: 8+ (Eskom/Sasol researchers, administrative, engineering and technical support) 1,000 m2 solar roof laboratory, staff office, workshop & control room 18 m lattice tower (multi-use) 600 °C,1.5 m3packed bed storage rig & 1,200 °C kiln Solar resource station with free web download (K&Z full tracker and shadow ring) ADA Solar water heating test facility 25 kWe Eskom McDonnel Douglas Stirling Dish Key SW: TRNSYS, Matlab, Flownex, Fluent & open source. Primary Grants: DST/NRF solar thermal spoke, Sasol Sr Researcher, Eskom Chair, SU Hope project, NRF THRIP. STERG infrastructure & resources

  7. STERG R&D overview STERG – Solar Thermal Energy Research Group Engineering (ME, EE, others) Physical,Social, Mathematical, Political, Statistical Sciences, Geography, Philosophy, etc. SUNSTEL(SU Solar Thermal Electricity Project) (Primary technologies: SUNSPOT, LFR, Dish) Other Better SWH | Coal power augmentation | other… System R&D Systems analysis | Plant thermodynamic models | Techno-economic analysis | Plant concepts & design Solar Resource R&D Satellite | Ground Dry Cooling Dry | Hybrid | Diurnal etc Heat Transfer Fluids & Storage CO2 | Air | NaK | Salt | Rock | Metal PCM Heliostats & Receivers Control | Drives | Optics | Field | Heat Transfer • Italics: On-going R&D

  8. Strategic activities at STERG 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

  9. Potential future strategic focus areas 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

  10. Outlook 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 “Let´s make SA a winner within CSP”
