Electrical energy storage (EES) systems - Part 5-3. Safety requirements for electrochemical based EES systems considering initially non-anticipated modifications, partial replacement, changing application, relocation and loading reused battery.
Energy storage requirements in photovoltaic power plants are reviewed. Li-ion and flywheel technologies are suitable for fulfilling the current grid codes. Supercapacitors will be preferred for providing future services. Li-ion and flow batteries can also provide market oriented services.
The technologies that are most suitable for grid-scale electricity storage are in the top right corner, with high powers and discharge times of hours or days (but not weeks or months). These are Pumped Hydropower, Hydrogen, Compressed air and Cryogenic Energy Storage (also known as ‘Liquid Air Energy Storage’ (LAES)).
While flow batteries could be an alternative option, Lithium-Ion or flywheel energy storage could also be used, specially in those particular cases where very high power is required (e.g. very large photovoltaic power plants). Black start is also one of the candidates to be required in the future grid codes.
Despite widely known hazards and safety design of grid-scale battery energy storage systems, there is a lack of established risk management schemes and models as compared to the chemical, aviation, nuclear and the petroleum industry.
The independent energy storage power stations are expected to be the mainstream, with shared energy storage emerging as the primary business model. There are four main profit models. Other ancillary services: Providing ancillary services such as black-start and voltage regulation.
