Electrical grid is a complex system that requires power supply and demand to be equal at any given moment, which is why viable storage solutions are emerging to help mitigate that power usage. Constant adjustment to the grid is required to maintain stability, and efficient storage will play a significant role in that critical balancing act, providing more flexibility and reliability to the system.
The key factors determining the selection of technologies for the future are the investment costs of the required storage units and the variable costs associated with the procurement of fossil energy carriers and CO2 certificates. The latter would open up new perspectives for man- aging an intermittent power supply. Ultimately, the political framework will be decisive.
