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 THERMAL COLLECTOR PERFORMANCE TEST

Client: Client: Kovco (Pty) Ltd

Scope: CRSES has been approached by Kovco (Pty) Ltd to assist them with improving their collector and to do a follow-up performance test of the new collector. The tests were performed at the solar roof testing facility of the Department of Mechanical and Mechatronic Engineering at Stellenbosch University.
Kovco provided CRSES with the following before testing commenced:

  • - One new flat-plate collector. Kovco was responsible for delivery and collection of the collector to/from the Department of Mechanical and Mechatronic Engineering at Stellenbosch University.
  • - Electronic copy of the collector specifications (dimensions, weights, etc.) and other supporting documentation if available (example: SABS system test certificates).

Outdoor tests were performed. The deliverable for this project was a test result datasheet. The datasheet provided all the data necessary to characterize the collector performance needed for R&D or simulation purposes. This will allow Kovco to compare their collector to existing collectors that have been tested (their own or other manufacturers where data is available). It will also make it possible to accurately simulate the performance of the collector for different regions, configurations and applications.
The data sheet provides the following:

  • - Photo of the test set-up
  • - Collector specifications
  • - Efficiency curve
  • - Test data points
  • - Incidence angle modifier curve

This work did not include thermal shock test, hail impact test, freeze tests or performance degradation tests over the life of the system.

BAPEPSA: Eskom

Client: Eskom

Scope: The Biomass Action Plan for Electricity Production in South Africa (BAPEPSA) was initiated through a G2G co-operation between the Netherlands and South Africa, and co-funded by the Netherlands Enterprise Agency and Eskom through an intergovernmental agreement. The main aspects to the BAPEPSA project are; • Resource quantification (woody biomass and agricultural); • Review and evaluation of available technologies for biomass use/conversion, fuel upgrading. • Identification of opportunities and barriers to implementation of biomass projects in South Africa BAPEPSA is focused on exploring biomass utilisation in the South African context for electricity generation using woody and agricultural biomass for on- and off-grid applications. The project defined the requirements to create an enabling environment and promote the uptake of biomass in South Africa. The project considered current and future biomass potential (local and regional), national strategies and directives and identify barriers to biomass utilization.

SOUTH AFRICAC ENERGY STORAGE TECHNOLOGY AND MARKET ASSESSMENT

Client: USTDA

Scope: The objective of the South Africa Energy Storage Technology and Market Assessment was to provide advisory services to the IDC and Steering Committee that will help guide and promote the adoption of energy storage technologies in South Africa. This effort included market research; technical, economic and financing assessments; development, environmental, and legal/regulatory assessments; and a roadmap that recommended steps, milestones and timelines for the adoption of energy storage technologies in South Africa through 2030. Although the advisory services provide some information related to residential, commercial, and industrial energy storage technologies, the focus of the advisory services has been on utility-scale (over 1 megawatt) energy storage technologies.

THE ROLE OF SOUTH AFRICAN MUNICIPALITIES IN RENEWABLE ENERGY: A Review of Business Models

Client: GIZ (SU in consortium with WWF-SA and TIPS)

Scope: This report reviews possible business models for South African municipalities to seize arising opportunities and minimise potential risks associated with the introduction of renewable energy technologies in the domestic electricity system. It proposes a typology of available business models for municipalities to seize emerging opportunities arising from renewable energy technologies. Three overarching roles, spilt into seven business models, are considered for municipalities: building electricity generation capacity; procuring electricity; and playing a facilitation function. Based on a three-pronged methodological framework taking into account the drivers of the business models; their techno-economic potential; and their ability to manage risks (regulatory, financial and socio-political); this report reviews each business model, highlighting their strengths and weaknesses.
