In another report, the Energy Transitions Commission (ETC) projects that the levelized cost of storage systems in India will reduce from $0.41 (~₹30.8)/kWh in 2018 to $0.17 (~₹12.8)/kWh in 2030. The report adopts a two-pronged approach to estimate the cost of Li-ion based MW scale battery storage systems in India.
By using the latent energy storage, the energy storage per unit volume increases dramatically. This high-density storage reduces the cost per unit of produced energy [12] . A spherically encapsulated energy storage unit (SEESU) is made by putting filler materials in a spherical container.

Energy Storage. The Office of Electricity''s (OE) Energy Storage Division accelerates bi-directional electrical energy storage technologies as a key component of the future-ready grid. The Division supports applied materials development to identify safe, low-cost, and earth-abundant elements that enable cost-effective long-duration storage.
5 · 3. Thermal energy storage. Thermal energy storage is used particularly in buildings and industrial processes. It involves storing excess energy – typically surplus energy from renewable sources, or waste heat – to be used later for heating, cooling or power generation. Liquids – such as water – or solid material - such as sand or rocks

Similar learning rates applied to redox flow ($414/kWh) may enable them to have a lower capital cost than PSH ($512/kWh) but still greater than lead -acid technology ($330/kWh).
With the mushrooming of distributed renewable generation, energy storage unit (ESU) is becoming increasingly important in residential energy systems.
