Storage solutions for renewable energy in UAE

Renewable energy is a big business in the UAE, its solar-power sector is growing really fast. It was forecasted that the industry would add 1,000 jobs over the coming two years. Still, a major difficulty remains in how to store the electricity the sector generates for the times when it is needed most.
One solution now being employed involves redox flow batteries (RFBs) that make use of the element vanadium (VRFBs). These can be used to convert electrical energy into chemical energy, which then can be turned back into electricity when needed. However, according to the Masdar Institute of Science and Technology, the technology needs substantial improvements, including cost reduction, increase of energy density and extending range of operational temperatures, which currently  are only between 10°C to 40°C. Read more at
