Long duration energy storage (LDES) will be crucial to our future energy systems and enable increasingly high levels of renewable penetration. As opposed to short duration storage that mainly provides system services, LDES allows for storing and dispatching energy on-demand rather than letting surplus renewable energy go to waste …

With longer duration storage, the energy contributions from the different technologies gradually revert to their levels without energy storage (y-axis intersect). Note that at the largest storage installation level (100 GWh), the share of the bio does not go back to the level of without ESS, because ESS provides the required flexibility instead of bio.
