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

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
