**9. Conclusion**

Arising from government policies to minimize greenhouse gas emissions and improve economic feasibility combined with storage, clean energy sources and more advanced storage systems in comparison of 20 years ago will inevitably increase dramatically over the next decades. To find out how this 'Grid of the Future' will look and work is a global problem that every nation will have to face in its own way. This continues to be a main theme of future studies, as developed and emerging countries face a wide variety of problems in terms of energy and power systems. While the prospects for decarbonizing the energy market are facing significant challenges in terms of technical breakthroughs, stationary energy storage has already achieved a competitive edge, partially due to cost declines in the production of batteries. The increase of incorporation of storage would lead to closer relations between supply and demand in the transition to a decarbonized energy environment. As a consequence, the value of the device would not depend on the volume and size of the hardware used, as is the case for current storage modes (hydro- or fossil fuel-based). Storage should also be known as an additional type of investment in grids (copper grid lines), an aspect of demand for service responsiveness, and a stabilizing factor for power grids. The energy storage market is increasingly shifting from an equipment-based industry to a service-based industry where various device players (generators, grid managers, aggregators, and final customers) will be given access to storage-related facilities. This summary of energy storage shows the future role of emerging services in the transition of energy systems. However, regulation and implementation of new market rules across MS in the EU are essential. In conclusion, despite all the above market problems, incomplete regulations, and the lack of legislation, the most important human factor is the ability to cooperate that EU member states must understand and ensure the functioning of the renewables market and their subsequent storage.
