Originally intended to be a booster station, Leliefontein’s location proved ideal for the establishment of a mini hydro-electric power station. The project, a marriage between the civil, mechanical and electrical engineering disciplines, shows how municipalities can use low cost, off the shelf equipment to generate clean power in their existing infrastructure. Wellington is home to […]
The Southern African Renewable Energy Association (SAREA) reports that Radisson Blu’s Granger Bay hotel in Cape Town has disconnected itself from the city’s drinking water network and sources its water via a seawater desalination system. The system draws water from a 100 m deep borehole under the hotel. The decision was made during the region’s […]
Industry uses more energy in the form of heat than as electricity, giving South African companies the perfect opportunity to exploit the country’s abundant solar and wind resources to produce power and heat for the re-industrialisation of the country. Speaking at the launch of two of Southern African Solar Thermal Training and Demonstration Initiative’s (Soltrain’s) […]
Growthpoint Properties has embarked on an exciting partnership with the Dutch green technology provider Waste Transformers by installing an on-site, anaerobic digester at its N1 City Mall property in Cape Town which uses organic waste to produce green electricity, hot water and fertiliser. The Waste Transformers unit is a modulated structure comprising four large containers that […]
Recor says its “swallow all” technology can convert waste into electricity, gas, heat, steam and even liquid fuels. The company says it has developed a world first containerised solution that delivers stored power and water from any type of waste. This is ideal for disaster relief programmes, remote off-grid communities, islands, war zones, etc. Apparently […]
Torqeedo’s Deep Blue product line offers the most powerful electric motor systems. Up until now, 50 kW was the maximum power available from a single Deep Blue motor. Twin installations could deliver a system power of up to 100 kW. The company will now launch its new Deep Blue 100 kW motors. Twin installations can […]
Gwakwani, a remote village located 300 km north of Polokwane, now has access to energy and water through sustainable interventions, thanks to the partnership between the University of Johannesburg’s (UJ’s) Department of Electrical and Electronic Engineering Science and Schneider Electric. A highlight of the project was the installation a solar-powered off-grid bakery, which not only caters […]
Water and energy conservation have become primary concerns among industries across the globe due to policies favouring and promoting the sustainable use of natural resources. Membrane-based treatment technology is highly valued for its efficiency and reliability. Smart-IoT enabled and digitalised sustainable solutions are the key growth factors in the water industry, which is characterised by […]
Mining coal and burning it in power stations uses large amounts of water, and pollutes even more water. It imposes massive but uncounted costs on society and particularly on poor people who live in the coal regions. A new report from the Life After Coal campaign calls for these costs to our water resources to be accounted […]
The total installed capacity of the large pumped storage schemes (PSSs) in South Africa is at present some 2910 MW. There are four large PPSs operating currently around the country, with the Steenbras (180 MW) being the municipal asset of the City of Cape Town, and three plants owned by the national entity Eskom namely […]
