Eskom, the state-owned electricity utility of South Africa, has begun tendering for a battery energy storage system (BESS) of minimum size and capacity 80MW / 320MWh.

Germany company Voltstorage, claiming to be the only developer and maker of home solar energy storage systems using vanadium flow batteries, raised €6 million (US$7.1 million) in July.

While lithium-ion batteries continue to take the dominant share of new installations by some distance, there are a variety of other technologies looking to complement, combine or even compete. Panellists at the Energy Storage Digital Series looked at the questions of which energy storage technologies are the likeliest contenders for that future.

Zinc-based battery energy storage manufacturer Eos Energy Storage has signed an agreement with an EPC partner to deploy systems based on its devices at rural microgrids, beginning with projects in Nigeria.

News in brief from around the world in energy storage.

A just-commissioned solar and battery storage system will reduce diesel consumption by at least 80% at a base for 300 humanitarian workers in South Sudan, managed by the UN’s International Organisation for Migration (IOM).

After we reported earlier this month that despite the impact of COVID-19, progress continues to be made on nearly every one of more than 70 projects underway by energy storage technology provider Fluence, here’s the full interview with Fluence’s chief operating officer John Zahurancik that that news story came from.

A survey of over 2,000 “senior business leaders” in G20 countries has found that electric vehicles and battery storage are the most popular assets to invest in among non-power generation technologies in the energy sector.

The cost of battery energy storage has continued on its trajectory downwards and now stands at US$150 per megawatt-hour for battery storage with four hours’ discharge duration, making it more and more competitive with fossil fuels. Andy Colthorpe spoke to Tifenn Brandily, lead author of BloombergNEF’s latest LCOE report.

Solar Media’s Liam Stoker and Andy Colthorpe discuss the continuing effects of COVID-19 on worldwide power markets, reflecting on IEA forecasts for historic energy demand lows and what they mean for renewables.
