Storage

The technology value chain of the storage sector can be subdivided as follows :

  • Electrochemical – conventional batteries
    • Lead-Acid Battery (LAB)
    • Nickel-Cadmium (NiCd)
    • Nickel–Metal Hydride (Ni-MH)
    • Sodium-Sulfur (NaS)
    • Lithium-ion (Li-ion)
    • Lithium-Sulfur (Li-S)
    • Metal-air
  • Electrochemical – flow battery
    • Zinc-Brome (ZBR)
    • Vanadium Redox (VRB)
  • Chemical – Synthetic Fuels
    • Fuel : Liquid Hydrogen, Hydrogen gas, Methane, Hythane
    • Application : Power to gas, Proton Exchange Membrane Fuel Cells (PEMFC), Solid Oxide Fuel Cells (SOFC)
    • Electrolyser : Proton Exchange Membrane (PEM), Electrolyser alkaline
  • Electrostatic / Magnetic
    • Supercapacitor
    • Superconductor Magnetic Energy Storage (SMES)

    • Compressed Air Energy Storage (CAES)
    • Gravity Hydraulic (STEP: Station of Transfer of Energy by Pumping)
    • Flywheel
  • Thermal
    • Sensible heat
    • Latent heat
    • Heat of reaction (thermochemical storage)
    • Seasonal thermal energy storage (STES)
  • Stationary / Embedded
    • Stationary storage (curative / palliative)
    • Embedded storage (cars, public transport, computers, …)
  • Domestic / Industrial
    • Domestic Storage
