A rapidly growing contribution by renewable energies to the overall energy production can be expected worldwide. Most renewables, like wind, PV or solar-thermal, are fluctuating resources. With increasing integration of renewable energies energy storage and energy balancing capacities are needed. So far the focus is on large, central and most cost effective energy storage technologies like pumped hydro or the conversion of surplus electricity into hydrogen. The potential and contribution of small and medium sized, Distributed Energy Storage (DES) technologies to balance fluctuation caused by renewable energies is mostly unexplored. Annex 28 DESIRE addresses this topic.
Key PlanEnergi activities
PlanEnergi is a sub-task leader in the project and is responsible for techno-economic modelling of the effect of decentral energy storage solutions on the energy system as a whole.
PlanEnergi and Aalborg University have published a report on the potential for using distributed energy storages for the integration of large amounts of fluctuating renewable energy. The report describes the results of the techno-economic energy system modelling carried out within the IEA ECES Annex 28 (DESIRE) project.
