TY - JOUR U1 - Zeitschriftenartikel, nicht wissenschaftlich A1 - Krüger, Christine T1 - Electric energy storage as an element of low-carbon energy supply N2 - Energy storage is one option to provide the electricity grid with flexibility. Short-term storage can provide system services for power quality, whereas medium-term storage allows to shift significant amounts of energy over some hours up to days. Seasonal or long-term storage can, for example, be provided by the power-to-gas technology. Significant amounts of storage will be necessary, especially when a fully renewable supply is approached. New mechanisms are needed to ensure anticipatorily that sufficient flexibility is in the system at any time.
