The process of storing and withdrawing energy can cause considerable losses. Many auxiliary components of the energy storage system have a constant power demand, and in addition, there are energy losses inherent in the storage principle. These losses can be very high in relation to the energy content.
Recent advancements in electrochemical energy storage technology, notably lithium-ion batteries, have seen progress in key technical areas, such as research and development, large-scale integration, safety measures, functional realisation, and engineering verification and large-scale application function verification has been achieved.
