South Africa: SHIP Opportunities in Agri-Processing and Textile Production

Submitted by Baerbel Epp on July 19, 2017
SHIP process heatSouth Africa shows large but untapped potential in terms of Solar Heat for Industrial Processes (SHIP). So far, there have been only seven systems in operation across the country and they provide heat in fields as varied as textile manufacturing (see photo), brewing, cheesemaking and automotive production. A recently published study titled Industrial scale solar heat in South Africa: Opportunities in agri-processing and textiles estimates the potential in agri-processing to be as high as 3.76 million m² of collector area and in textile manufacturing at around 519,000 m² (see the attached document). The 72-page document written by the WWF South Africa in cooperation with the Centre for Renewable and Sustainable Energy Studies (CRSES) of Stellenbosch University and non-profit organisation GreenCape looks at the key drivers for and barriers to increased SHIP deployment in the southernmost country in Africa.

South Africa: Solar Green Beer Production Creates High IRR

CBC Installation South AfricaSouth Africa’s solar process heat installations remain profitable when they have to compete against other heat sources, such as diesel, paraffin, petrol or gas, the Centre for Renewable and Sustainable Energy Studies (CRSES) at Stellenbosch University, South Africa, has concluded in a recently published paper. The researchers at the CRSES conducted a feasibility study of a 120.7 m² collector field that was to cover 60 % of the existing hot water requirements of Cape Brewing Company (CBC) based in Suider-Paarl, Western Cape, and analysed ten proposals submitted after the company’s invitation to tender in January 2015. South African E3 Energy won by offering an installation with a levelised cost of energy of 7.9 EUR cents/kWh, an internal rate of return of 16.7 % and a payback period of 9.3 years. CBC´s daily hot water demand is estimated to be 7,000 litres at 85 °C during 245 days a year, i.e., during a full year except for weekends, public holidays and two weeks of summer holidays. The system went into operation in November 2015 and the COO of CBC, Andy Kung, seems satisfied with the performance and the energy saving it offers.
