Recent developments in storage technology and applications

  Electrical energy storage systems (ESS) are becoming increasingly important in both the renewable energy and the smart grid sectors, as more operators are realising that without ESS it will be difficult to progress forward. Although it was regarded in the past as too expensive, storage is now seen to be an essential economic solution […]

Suspect solar panels stunt growth of community crèche

  The opening of a community crèche as reported in October 2014 (www.ee.co.za/article/shaping-future-roots.html), was greeted with great expectations. The crèche is regarded as a major benefit the community and as a successful social upliftment programme. The performance of the main solar power system has been less than encouraging, and has affected the functioning of the […]

Wits students show they can work under pressure

  Final year students at the Witwatersrand School of Electrical and Information Engineering showed great ingenuity in the projects they presented at the annual open day on 15 October 2014. In introducing the event, school head Prof. Fambirai Takawira said that students were given only six weeks to develop, design and build their projects. “The […]

Lithium batteries: Best energy storage technology

  Wind and solar power are inherently intermittent energy sources. Energy has to be stored during productive periods so that these fluctuations can be compensated for. The focus lies on battery systems which used to be too expensive to be employed on a large scale. Now, a number of different electrochemical technologies are competing to become the benchmark. […]
