CENTRE FOR RENEWABLE AND SUSTAINABLE ENERGY STUDIES

LIST OF COMPLETED PROJECTS

CRSES has a team of competent engineers and project managers who can assist clients with on- and off-grid renewable energy solutions. The dynamic group includes engineering expertise in the following disciplines: Mechanical, Mechatronic, Electrical, Process and Civil. The Centre is also well positioned to assemble expertise from the broader University community and private industry to participate in multidisciplinary projects. The past projects are listed under each year below:

SOLAR WATER HEATING SYSTEMS IN STILL BAY AND KWANOKUTHULA

Client: Western Cape Provincial Government: Department of Environmental Affairs and Development Planning

Scope: Investigate if the mass roll-out of solar water heaters in Still Bay and Kwanokuthula can reduce the peak electricity usage during the summer holiday season and delay the upgrading of the existing substation. The study further included the feasibility of installing solar water heaters in the low cost housing area Kwanokuthula near Riversdale.

Continuation: 184 SWH systems (80 liter, closed coupled, flat plate panel collectors) were installed in Kwanokuthula. After the installation three visits to the area were completed: The first a few weeks after the installation, the second during winter and the final during summer to conduct interviews with the residents to determine the social and economic impact of the project.

OBSTACLES AND BARRIERS TO RENEWABLE ENERGY IN SA

Client: Department of Environmental Affairs and Tourism, DEAT

Scope: To study and write a report of the barriers to the development of a renewable energy industry in South Africa.

AGULHAS CFD

Client: Eskom

Scope: To develop a computational fluid dynamics model of the ocean and later specifically of the Agulhas ocean current to determine the influence of tidal variation on the flow-speed of the current.

HELIOSTAT DESIGN OPTIMISATION

Client: Eskom

Scope: To conduct a study for Eskom on their proposed 100 MWe CSP plant near Upington to optimise the heliostat field layout as well as some of the components of the structure of the heliostats.

Continuation: A postdoc and masters student is continuing this work.

THERMAL PERFORMANCE TESTING OF AMASOLO SOLAR WATER HEATER

Client: Amasola SWHs

Scope: Test the thermal performance characteristics of a novel low cost solar water heater design.

Main Conclusions: The solar water was tested in parallel with a commercially available solar water heater. The Amasola had a lower thermal performance than the commercial low cost solar water heater at a higher cost. Based on this the Amasola system is not rated as a technology that should be further developed.

Continuation: None

(GLOBAL ENGINEERING TEAMS)

Client: Technical University of Berlin / Kwezi V3

Scope: Oversee four students (two South African and two German) on a post graduate research project on efficient cooling and heating of buildings.

Main Conclusions: The final report was delivered to Kwezi V3

Continuation: None
