With the continuous increasing energy demand and the depleting supply of fossil fuel sources, Renewables will become a major energy source in the future. In order to integrate Renewables, our society is facing several major challenges, e.g. coping with the intermittency, transporting electricity cross large distances and demand side management.
There are several scenarios that offer possible solutions
Renewables cost reduction and reaching grid parity
Energy storage technologies available for both generation side and grid side
Large scale high voltage transmission
Using fossil fuel (mainly gas) to bridge the intermittency
To utilize these solutions, energy storage solutions will play an important role in all possible scenarios.
