SOLAR POWERED VARIABLE SPEED DRIVES FOR REMOTE BOREHOLE APPLICATIONS -ZEST WEG GROUP

SOLAR POWERED VARIABLE SPEED DRIVES FOR REMOTE BOREHOLE APPLICATIONS

Farmers are making increasing use of photovoltaic solar panels and variable speed drives (VSDs) to get clean and continuous power to their boreholes in remote locations, cutting out the need for costly infrastructure and cables to link with the main grid. Zest WEG Group, a subsidiary of leading Brazilian motors and controls manufacturer WEG, supplies these stand-alone electrical solutions so that users in the agricultural sector can immediately benefit from ‘free’ solar power for pumping water. As a key element of this arrangement, the VSD protects the motor from the…

Algal biofuel production is neither environmentally nor commercially sustainable

Modern biofuels have been touted as a greener alternative to petrol and diesel since the early 1900s. It seems like a good idea on paper, and they do work – but their use and production doesn’t come without problems. The first generation of biofuels – mainly ethanol made from plant crops – and second generation, derived from plant and animal waste streams, both had environmentalists and others concerned about the competition for land and nutrients between biofuels production and food production. It was with a lot of hope, and hype, that production of the third generation…

Hulisani bets on wind tower firm

Hulisani, the black-owned energy investment company, has made its third acquisition in three months by injecting R82.5m into wind tower manufacturer GRI Wind Steel SA. The move appears surprising because SA’s renewable energy sector has stalled on Eskom’s refusal to sign offtake agreements with successful bidders in the latest round of projects, citing affordability. Eskom has told Parliament that several conditions need to be met before it signs agreements, including completion of the Integrated Resource Plan. Its refusal has jeopardised the future of manufacturers of wind towers and solar photovoltaic…

Finding a renewable storage solution

Currently, energy produced by solar or wind costs around 60c per kilowatt hour produced, and roughly R1 per kilowatt hour for coal-fired power stations. However, the cost of storage raises the cost of renewable energy above that of coal-fired power stations. But a team, led by Professor Bernard Bladergroen, at the University of the Western Cape’s (UWC) Energy Storage Innovation Laboratory (Esil) is working to find a solution to the energy storage problem, and to make the cost of solar and wind energy comparable, if not lower than that produced…
