“Energy Storage” has become the new buzzword in the context of the energy transition. Power fluctuations caused by wind power and photovoltaics have led to a decoupling of electricity generation and demand. In the course of the expansion of installed renewable capacity, fluctuations in the power grid (displayed as gradients of renewable generation) have increased (see figure below).

The challenges for grid operators increased due to the expansion of installed renewable power generation capacities. They have to take various measures to stabilize the power grid. This can be seen from the increase in Redispatch over the last years. In addition, power generation from wind and photovoltaics has to be increasingly curtailed (see figure below).
Development of Redispatch und Curtailment between 2011 and 2018
This problem is expected to become more severe in the future. Economically usable energy storage technologies have the potential to make the energy transition manageable. Energy Storage could enable the cross-sectoral utilization of CO2-free renewable electricity and become a decisive link between the power, gas, heating and mobility sectors.
Energy storage solutions enter the market
Energy storage solutions are suited to absorb excess power and make it usable with a time-delay or for mobile applications. This includes battery storage (as home storage systems or large scale storage systems), the Power-to-X technologies (such as Power-to-Heat and Power-to-Gas), as well as pumped-hydro storage and flywheel energy storage systems. The different storage technologies have different properties, e.g. regarding storage capacity and storage duration (see figure below), which strongly influence their suitability for various applications.
