Long-Lasting Grid Batteries – Why Iron-Based Batteries May Be Key To Decarbonisation

While development of renewable energy sources, and how the energy produced may be distributed over our national grids, is advancing at a rapid rate, one problem still remains - what happens to our energy production from renewable sources when the sun sets and the wind stops blowing?

One obvious solution would be to use a large energy storage means (e.g. batteries) to help even out energy production when supplies from renewable are low, with such storage mean storing excess energy during times of high production. To provide power for large populous areas or even entire countries, the scale of any such such storage means needs to be huge, and distribution networks set up for varying energy provision between renewable sources and storage batteries. Ultimately though, being able to store energy from renewable sources for hours or even days at a time, and then being able to distribute said energy in times of low supply would be a huge step forward in the use of clean power.
