It can be created from three basic and cheap materials: water, cement and carbon black.

For many years now, our daily lives depend enormously on the supply of energy to sustain and drive all the products and services we need. For this reason, researchers have also been working for many years to find better solutions for energy storage that are also as sustainable and green as possible.

Although we already have clean sources of energy, such as the sun, wind or water, it is not always sunny, windy or there are many waves, and therefore we do not have this energy constantly and we have to store it in some way to not lose it.

The solution we currently have for this is batteries, but these have the drawback that they are generally made of lithium, an increasingly scarce material that cannot withstand the very high demand that this modern world demands of it.

For that reason, researchers at the Massachusetts Institute of Technology (MIT) in the US have found a way to create an energy storage device known as a supercapacitor from three basic and cheap materials: water, cement and a substance called carbon black. 

These supercapacitors are very efficient at storing energy and differ from batteries in that they charge faster.

Researchers assure that this supercapacitor can be a revolution in decarbonizing the world economy.

This product could be used on the walls and columns of buildings to store batteries or in the same way it could be used on roads to emit energy when cars pass by and even charge them wirelessly.

The problem is that on paper, this concrete sounds like the solution of the future for storage.
