The lack of direct support for energy storage from governments, the non-announcement of confirmed needs for storage through official government sources, and the existence of incomplete and unclear processes in licensing also hurt attracting investors in the field of storage (Ugarte et al.).
But currently, the running programs and unbalanced pricing in the market, the lack of certainty and certainty in regulatory affairs and the economy, are challenges that prevent investors from entering the field of energy storage (Castagneto Gissey et al., 2018).
If large scale battery storage systems, for example, are defined under law as ‘consumers’ of electricity stored into the storage system will be subject to several levies and taxes that are imposed on the consumption of electricity.
This research intends to fill these gaps by performing a systems-level investigation of the integration of storage into existing electric power systems, overly analyzing every strategic scenario for cost reduction and associated economic scenarios, and reviewing regulation policies that may encourage high storage system penetration.
As discussed in this review, there are still numerous challenges associated with the integration of large-scale battery energy storage into the electric grid. These challenges range from scientific and technical issues, to policy issues limiting the ability to deploy this emergent technology, and even social challenges.
Research at the cross section of nanomaterials and electrochemistry will enable the energy storage research community to push the boundaries of the lifetime and power densities of Li-ion batteries. Advances improving calendar and cycle life would relax the periodical need for large quantity of rare materials to replace old batteries.

Principle of Energy Storage Switch | Nader Circuit Breaker
The so-called energy storage means that when the circuit breaker is de-energized (that is, when it is opened), it opens quickly due to the spring force of the energy storage switch. Of course, the faster the circuit breaker is opened, the better. This is to have enough power to separate the contacts when the segmentation fault has a large current (excessive current will melt the …
