With the advent of energy storage era, what is the future development trend?
Looking at the development of the global energy storage industry, countries have formulated and implemented many incentive policies and subsidies to promote the sustainable development of the energy storage industry. Looking ahead, the energy storage industry is expected to show explosive growth, driven by the rapid development of renewable energy industry, electric vehicle industry and energy Internet industry.
Experts pointed out that in the future energy pattern, energy storage products and services will comprehensively cover the three major energy use fields of transportation, construction and industry. Electrochemical energy storage technology will become the mainstream energy storage technology. Comprehensive energy services and smart energy technology will become the basic configuration of energy enterprises in the future. Electricity combined with energy storage will replace traditional energy and become one of the most important international trade commodities in the new era.
At present, the global energy storage market has huge development potential. Facing the huge market space, China's energy storage industry may usher in the wind. In addition, the performance and cost of the battery system determine the large-scale promotion and application of energy storage, which is a bottleneck problem affecting the rapid development of the industry. Some experts predict that the technical development route of energy storage battery will be gradually clear in the next 10 years.
The prediction of the future global energy storage market scale by major institutions around the world shows that the development potential of the energy storage market is huge. According to the prediction of all parties, the installed capacity of energy storage in the world is expected to triple by 2030. The growth of energy storage is mainly driven by the promotion of renewable energy and the improvement of power system requirements. It is expected that the development of renewable energy power generation, distributed power generation, smart grid and electric vehicle markets will drive further growth of the global energy storage market. At the same time, it is predicted that although there are still many large-scale pumped storage power station projects under planning, in the long run, the proportion of pumped storage power stations in the installed energy storage structure will show a decreasing trend.
In addition, as the demand for renewable energy continues to grow, long-term energy storage will become more important. The average continuous discharge time of the energy storage system will increase by more than 2 hours, which has already taken place in the American market. Analysts predict that the global market will catch up with this trend in 2022.
Look back at the development road of China's energy storage industry. With the "double carbon" east wind, the energy storage industry has ushered in an unprecedented attention and hot investment climax. In 2021, the state and local governments will introduce more than 300 energy storage related policies, and the industrial chain investment plan has exceeded 1.2 trillion. New energy storage enterprises will also make great breakthroughs in financing and technology, and the large-scale development of energy storage has arrived.
However, objectively speaking, at present, China's energy storage industry is still in the early stage of large-scale application, and some relevant technical standards are not perfect. In contrast, foreign energy storage commercialization models have been relatively mature, and their energy storage policies, business models and successful experiences may give us some inspiration.
