3 key renewable energy stocks to watch amid batteries revolution

Battery storage plays a very important role in expanding the scope of renewable power generation.  Researchers have recently identified a new battery that is expected to be more cost-effective than traditional lithium-ion batteries. These new batteries would expedite the shift from fossil fuels to renewable power sources.

Lithium-ion batteries are used widely in various products ranging from mobiles to electric vehicles. However, producing these batteries is a relatively expensive process and thus is unsuitable for large-scale production needed in solar and wind power installations.

When the sunlight isn't enough or the winds are weak, energy suppliers find it difficult to fulfill the power demand. Therefore, a global group of scholars have stepped up with the idea of this low-cost battery made with inexpensive and considerable supplies, which would potentially enhance energy storage.

The analysis was led by MIT professor Donald Sadoway, who said he wanted to create a better battery than the standard lithium-ion battery, initially for stationary storage on small-scale, and in due course, for automotive uses.

Collaborating with experts from institutions in the US, Canada, and China, Professor Sadoway attempted to invent a suitable battery made up of the extensively available metal aluminium and the highly affordable non-metal sulphur.

As the batteries get revolutionised, the scope of renewable energy will keep growing. UK investors can thus keep an eye on the following renewable energy stocks suggested by Kalkine Media® for strengthening their portfolio in the long run.
