Energy storage technology is known as the "underpinning technology of the energy revolution" and will play a significant role in many aspects.

1. For the power system, energy storage can provide a variety of services for the power grid, such as peak regulation and frequency regulation, peak cutting and valley filling, black start, demand response support, etc., to improve the flexibility, economy and security of the traditional power system.

2. In terms of renewable energy development, energy storage can significantly improve the consumption level of wind and solar power generation, and support distributed power and micro-grid.

With the increasing maturity of distributed energy technologies such as distributed photovoltaic, small biomass energy, natural gas cold-heat-electricity triple supply, and fuel cells, as well as the progress of related technologies such as energy storage and digitalization, distributed energy will develop more rapidly in the future.

3. In terms of transportation, energy storage will play a key role in the intelligent transportation network including energy interconnection and integration of new energy vehicles.

Potentially disruptive to the energy industry are new battery energy storage technologies based on new materials, such as graphene supercapacitors, carbon nanomaterial self-storage devices, and superconducting electromagnetic energy storage technology.

If low-cost and high-efficiency energy storage technology appears and is put into large-scale commercial application, it will greatly promote the development of renewable energy, and make new energy transportation large-scale or even completely replace fuel transportation.

Controlled nuclear fusion technology

Nuclear fusion energy is the ultimate energy in human ideal, with many advantages. There are two main technologies for controlled fusion, namely magnetic confinement fusion (MFC) and inertial confinement fusion (IFC).

At present, there are many research projects related to nuclear fusion in the world, Such as the International Thermonuclear Experimental Reactor (ITER) project, the United States National Ignition Facility (NIF), the United States suspended Dipole test facility (LDX), the United States Z-IFE device, the United States Lawrenceville Plasma Physics research project, the United States FRX-L Research projects, General Fusion in Canada, the European High Power Laser Energy Research (HiPER) Program, and Wendelstein 7-X in Germany, among others.

China, which officially joined the ITER project in 2007, is also vigorously promoting domestic fusion science and technology research.

China has successfully completed the conceptual design of fusion Engineering Experimental reactor (CFETR), and is now carrying out engineering design.

Large scientific facilities such as the China Circulation Apparatus 2A (HL-2A) and the Fully superconducting Tokamak Nuclear Fusion Experimental Facility (EAST) have also been built, and many physical experimental research achievements rank among the top in the world. HL-2A has realized the configuration discharge of the diverter and the operation in high constraint mode for the first time in China. In July 2017, EAST achieved the world's first high confinement operation of 50 million degree plasma continuous discharge for 101.2 seconds, once again setting a new world record for magnetic confinement nuclear fusion research.
