Impact of energy storage system policy ESS policies are the reason storage technologies are developing and being utilised at a very high rate. Storage technologies are now moving in parallel with renewable energy technology in terms of development as they support each other.
These policies are mostly concentrated around battery storage system, which is considered to be the fastest growing energy storage technology due to its efficiency, flexibility and rapidly decreasing cost. ESS policies are primarily found in regions with highly developed economies, that have advanced knowledge and expertise in the sector.
The novel portable energy storage technology, which carries energy using hydrogen, is an innovative energy storage strategy because it can store twice as much energy at the same 2.9 L level as conventional energy storage systems. This system is quite effective and can produce electricity continuously for 38 h without requiring any start-up time.
In general, policies are designed to establish boundaries and provide regulatory guidelines. According to the Energy Storage Association (ESA), the policy tools fall under three categories which are value, access and competition .
During this period, the management system, incentive policies and business models of energy storage were mainly explored. It is expected that from 2021 to 2025, energy storage will enter the stage of large-scale development and have the conditions for large-scale commercialization .
The International Energy Agency (IEA) estimates that in the first quarter of 2020, 30% of the global electricity supply was provided by renewable energy . ESS policy has made a positive impact on transport storage by providing alternatives to fossil fuels such as battery, super-capacitor and fuel cells.
