Recently, the Ministry of Science and Technology solicited opinions on the 2022 project application guidelines for the key special project of the “14th Five-Year Plan” national key research and development plan “Energy Storage and Smart Grid Technology”.
The 2022 guidelines are planned to focus on medium and long-term scale energy storage technology, short-term high-frequency energy storage technology, ultra-long-term scale energy storage technology, high-proportion renewable energy active support technology, safe and efficient operation technology of super-large AC-DC hybrid power grid, there are 7 technical directions of multi-user supply and demand interactive electricity consumption and energy efficiency improvement technology, and basic support technology, and 26 guiding tasks have been launched.
It involves nine energy storage sub-tasks, including low-cost and long-life manganese-based energy storage lithium-ion batteries, organic energy storage batteries, water-based metal-ion energy storage batteries, 100-megawatt-hour sodium-ion battery energy storage technology, and high-power lithium-ion batteries. Battery energy storage technology, high-power dual-ion energy storage battery, 100MW advanced compressed air energy storage technology, new generation flow battery energy storage technology, wide liquid temperature range high temperature molten salt heat storage technology.
