The proportion of renewable energy is increasing, and lithium storage technology has great potential. Nowadays, renewable energy with its renewable, clean, green, more and more favored by countries around the world, the development of renewable energy power has a total of large, fast development of the two major trends, for the development of renewable energy, to explore a more environmentally friendly, safer, more economical lithium storage technology route, so as to reduce the cost of power generation, improve energy utilization is the direction of development.

As we all know, renewable energy refers to the energy that can be continuously regenerated and used forever in nature, with the characteristics of inexhaustible, mainly including solar energy, wind energy, water energy, biomass, geothermal energy and ocean energy and other energy. At present, solar energy, wind energy and water energy are the three main forms.
China's renewable energy is in a rapid development stage, and some technologies have already reached or are close to the level of commercial development, whether from the perspective of resources, technology and industry, there is the potential for large-scale development in the near future. Renewable energy has already started to play a role in China's energy supply, and can have a pivotal position in the future composition of energy supply.
As of March 2020, the cumulative installed capacity of renewable energy power generation in China reached 802 million kilowatts, including 213 million kilowatts of wind power and 208 million kilowatts of photovoltaic power generation. In the future, China's renewable energy generation gradually increase the proportion, more than 50% in 2040, reaching about 67% in 2050, renewable energy will gradually become the first major power source of the power system. Lithium energy storage in the field of renewable energy has great potential!
As the proportion of renewable energy increases, the stability and flexibility of the power supply is increasingly important to the system, and lithium battery storage technology has great potential to improve the flexibility of the entire energy sector and can achieve a high share of renewable energy in the power system. Currently, the configuration of lithium storage is becoming a pre-requisite for new energy grid connection or approval.
For distributed renewables (wind and solar), lithium storage technology is even more important. Distributed energy mainly refers to the energy supply built on the customer side, can be run independently or grid-connected, according to the user's multiple energy needs, using demand-responsive design of the new energy system, is to maximize the resources and environmental benefits of decentralized energy supply system.
Since the losses in the transmission chain can be reduced, energy utilization efficiency can be improved. However, also due to the instability of wind and solar energy, lithium battery energy storage means is one of the necessary conditions for the large-scale development of distributed renewable energy. Therefore, it can be said that energy storage technology can really change the human energy supply.
Lithium battery energy storage may be an effective economic solution to the instability of renewable energy generation. The benefits of battery energy storage are that it can be large or small, easily combined with various scales of renewable energy generation; fast charging and discharging, direct electricity to electricity conversion, and high conversion efficiency. The biggest factor in its limitation is the economics, as well as the charging and discharging efficiency, safety, and lifetime associated with the cost.
For the power grid, the development of lithium battery energy storage technology or can fundamentally solve the instability of renewable energy generation, large-scale expansion of the share of renewable energy generation, and effectively improve the rate of grid connection and system stability. For the government, the development of more targeted and differentiated differential tariff policy, not only helps to promote the profitability of lithium storage technology, but also to a greater extent to optimize the allocation of power resources and improve the overall power generation efficiency of the power system.
With the future of the world's renewable energy development process to further accelerate the overall renewable energy market shows a "promising" trend, and in this context, those who are the leading lithium battery industry is expected to take the lead in benefiting.
Summary: Battery energy storage is the key to the large-scale development of renewable energy, with the development of renewable energy, the safety and stability of the power system and flexibility is becoming more and more important, lithium storage will have great potential for development.
