With the rapid growth of solar and wind energy, a new challenge arises: how to store renewable electricity to warrant a continuous energy supply? A series of different electricity storage technologies exists (pumped hydropower, compressed air, Li-ion batteries, etc.), but none of them has enough geographical possibilities or material abundancy to store sufficient electricity for a global transition to solar and wind energy only. Therefore, new storage technologies are being investigated. I will present 2 new types of batteries that run on water and (NaCl) salt only, developed by AquaBattery, and compare it power-to-gas and power-to-liquid routes that my group are working on at TU Delft. A pilot plant facility of the salt water-based battery (10 kWh) demonstrates the technical operation and feasibility of such battery, and options for large-scale energy storage will be discussed in this presentation.
