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:
CONDUCTING RESEARCH ON THE GREEN ECONOMY IN KWAZULU-NATAL (Contract 2)
Scope:After the successful completion of the first KZN Government funded project, the contract has been extended to keep on conducting research on the Green Economy in KwaZulu-Natal. This project was again divided into two sub-projects:
- 1. KwaZulu-Natal Renewable Energy Development Potential GIS Study
- 2. KwaZulu-Natal Sustainable Energy Investment Policy (SEIP)
SOLTRAIN II: Southern African Solar Thermal Training and Demonstration Initiative
Client: AEE Intec, Institute for Sustainable Technologies
Scope: SOLTRAIN (Southern African Solar Thermal Training and Demonstration Initiative) is funded by the Austrian Development Agency and one of the main activities is focussed awareness campaigns of solar thermal applications for specific stakeholders and to highlight the impacts of energy savings and secure supply.
With solar thermal energy we refer to all technologies that convert solar energy into useful thermal energy. This includes solar water heating and cooling for residential, commercial and industrial applications using non-concentrating and concentrating solar collectors.
Status: Completed (2012-2016)
THIN FILM PV PEER REVIEW
Client: First Solar
Scope: First Solar approached the Centre for Renewable and Sustainable Energy Studies (CRSES) to conduct a peer review on papers written on thin film photovoltaic (PV) technology. First Solar has conducted previous technology peer reviews in Europe, Asia, the Middle East and South America and would like to expand the peer review to South Africa.
PV POTENTIAL IN THE WESTERN CAPE
Client: Western Cape Government, Department of the Premier
Scope: Following on from an Energy Design Lab held in early 2015, the Department of the Premier, Western Cape Government, there is a need to set a clear, bold action agenda on energy security for the WCG and local municipalities in order to minimise the impact of power shortages on the region’s economy in the next 5 years and improve long-term energy security of the region and the country.
In order to address this need, small scale embedded generation, and in particular solar photovoltaic (PV) electricity generation has been identified as a key intervention that can be rolled out in the short term. For this reason, Stellenbosch University, through CRSES, was contracted to quantify the maximum installation capacity of PV for the region and model the impact that this installed PV capacity will have on balanced electricity supply and demand.
Client:TIA, Stellenbosch University, DST and SANEDI
Scope: James van der Walt, a master’s degree student, developed a promising solution for rural electrification. He came up with the concept of using a refurbished container with solar panels that houses a battery charging station, mainly to have a safe and secure storage facility for the equipment at night. The aptly-named SolarTurtle functions as a micro-utility where consumers can recharge batteries during the day to provide light or power to appliances such as television sets, at night. Van der Walt is currently supported by the Technology Innovation Agency, Stellenbosch University, the Department of Science and Technology and the South African National Energy Development Institute to commercialise the concept by developing a pilot plant that will be deployed in the Eastern Cape. The project was selected as one of the finalists in the Western Cape’s Better Living Challenge, and was exhibited at the BLC Showcase in October 2014. James also received the WWF-SA Climate Solver Award on 6 March 2014.
IMPACT OF INCREASED RENEWABLE ENERGY GENERATION ON THE SOUTH AFRICAN GRID AND IMPLICATIONS FOR MUNICIPALITIES
Scope: Part A:
Performed a set of spatial-temporal analyses using methods developed at Stellenbosch University to conceptually evaluate the feasibility and cost of a 2030 electricity system that delivers 20% of the annual electricity by renewables and generally conforms to the technologies outlined by supporting technologies and demand assumptions provided by WWF-SA.
Scope: Part B: The Drakenstein Project Client: WWF-SA Scope: An analysis of the potential impacts of the installation of rooftop PV on municipal revenue, using Drakenstein Municipality as a case study. The study included the potential for municipalities to play a more pro-active role in the roll out of distributed energy to address electricity constraints and generate income and PV feasibility studies of three municipal buildings.
SOLAR WATER HEATING SYSTEM PERFORMANCE TESTS
Scope: A client developed an innovative new AC/DC heating element which could be used in conjunction with PV panels to form a solar water heating system. CRSES tested the new system performance and compared it to an existing solar thermal water heating system.
