EU P2G platform Copenhagen 22.06.2016 State of affairs By Denis Thomas, Hydrogenics EU Regulatory Affairs & Business Development Manager Renewable Hydrogen
The EU definition of energy storage Energy storage in the electricity system would be defined as the act of deferring an amount of the energy that was generated to the moment of use, either as final energy or converted into another energy carrier. Development and financing of energy storage could therefore rely on a number of principles: Energy storage should be developed to the extent the overall costs of the new energy system are lower with storage than without storage; In relation to the electricity grid, energy storage should be rewarded for the services provided on a peer basis with the alternative suppliers for those services, being demand response or flexible generation; Energy storage as a supporting mean for integrating variable renewable energy (vre) should be rewarded for the contribution to improving energy security and decarbonisation of the electricity grid or other economic sectors; the avoided costs of vre curtailment and the carbon reductions of the backup capacities could support the business case of large scale energy storage; When a generator or a consumer choses to integrate a storage facility at its location, this should not lead to less favourable treatment, neither in terms of obligations nor in terms of eventual support that it receives in the energy system. 22
