Abstract:

In the context of global carbon neutrality, the international energy pattern is changing from the absolute dominance of fossil energy to the integration of low-carbon and multi-energy. As a key technology for promoting the transformation of renewable energy from alternative energy to main energy, the energy storage technology has attracted increasing attention from the industry. This study analyzes the strategic layout, project deployment, and key demonstration projects of the electrochemical energy storage technology in the United States, the European Union, Japan, and other major countries as well as regions. China has committed to carbon peak by 2030 and carbon neutral by 2060. In relation to this, the Chinese government has paid increasing attention to the development of the electrochemical energy storage technology by issuing a series of supporting policies, launching major research and development projects to perform technical research, and deploying several demonstration projects for electrochemical energy storage. However, although China has made efforts to catch up with advanced-technology countries, such as Europe, the United States, Japan, and South Korea, in terms of the electrochemical energy storage manufacturing technology, a certain gap remains to exist between China and these developed countries when it comes to energy storage battery mechanism research, technological breakthrough, and key material manufacturing. The demonstration and application of various types of electrochemical energy storage technology in China have just started. Therefore, further measures must be taken from the aspects of top-level design, technology research and development, industrial layout, and infrastructure construction to accelerate the wide application of the new next-generation electrochemical energy storage technology, promote energy-efficient utilization, multi-energy integration, and complementarization, and build a "clean, low-carbon, safe, efficient, and modern" energy pattern.
