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
Andasol 3: Facts & Figures Owner: Marquesado Solar S.L. Location: Aldeire/La Calahorra
(Granada, Spain) Capacity: 50 MWel Forecasted electricity
production: ~200 GWh/a Commissioning in autumn 2011 Annual CO2 savings:

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

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
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
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
“Let´s make SA a winner within CSP”
