Storage Systems for Increased Flexibility

The energy transition will not be able to succeed without energy storage solutions. Energy storage is becoming an increasingly important factor in energy systems with a high share of electricity fed in from volatile renewable energy sources and changing usage structures, for example, due to electromobility. Storage technologies have evolved at a fast pace over the last few years. Given the above-average intensity of research, many further innovations and a continued reduction in costs are expected in the future (IEA, 2020).
