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.
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.
ESS policies mostly promote energy storage by providing incentives, soft loans, targets and a level playing field. Nevertheless, a relatively small number of countries around the world have implemented the ESS policies.
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 .
The UK’s energy system relies on the storage of fossil fuels to manage variations in supply and demand over varying timescales. As these are replaced to meet the net zero emissions target, new types of longer duration energy storage will be needed to provide secure energy supplies.
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.
