Energy storage refers to the storage of energy through media or equipment, and thenreleaseProcess.[5]Energy storage is also oilReservoirA noun in, representingReservoirThe ability to store oil and gas.
On April 2, 2024, the National Energy Administration issued a notice on promoting the grid connection and dispatching of new energy storage (GNFGJG [2024] No. 26), requiring to accelerate the planning and construction of new energy systems, standardize the grid connection management of new energy storage, optimize the dispatching operation mechanism, fully play the role of new energy storage, and support the construction of new power systems.[11]
Research and development of new and renewable energy, seeking to improveEnergy utilization rateThe advanced method of.For such a Chineseenergy production Compared with big consumer countriesconserve energy ,reduce emissionsThere is also the need for energy growth to support economic development, which needs to vigorously develop the energy storage industry.
analysis reportShows that the growingEnergy consumption, especially coal, oil, etcfossil fuelThe massive use ofglobal climateThe impact brought by this makes the goal of human sustainable development face a serious threat.It is predicted that if the current miningNon renewable energyThe useful life of coal, natural gas and oil is estimated to be 100-120 years, 30-50 years and 18-30 years, respectively, based on the technology and the rate of continuous day and night consumption of these fossil fuels.Obviously, the biggest problem and dilemma facing the 21st century may not be war and food, but energy.
On January 19, 2016, the World Energy Agency said that due to the newSolar cellTechnology and othersScientific and technological progressPromote the price decline, and the cost of battery energy storage will decline by 70% in the next 15 years.
Energy storage itself is not an emerging technology, but it is just emerging from the perspective of industry and is in its infancy.China has not reached the level that the United States and Japan treat energy storage as an independent industry and issue special support policies. Especially in the absence of a mechanism to pay for energy storage, the commercialization model of energy storage industry has not yet taken shape.

Xue Zhanhai, on behalf of the Municipal Party Committee and the Municipal Government, welcomed and thanked all the experts and entrepreneurs who came to the promotion meeting.He mentioned that Yan'an is a highland for entrepreneurship and innovation and a good place for investment and industry. Accelerating transformation and development has resource advantages, industrial foundation, basic conditions, and park platform support, especially Yan'an High tech Zone to accelerate the construction of high-techIndustrial New Town, forHigh tech industryStrategic emergingIndustrial developmentIt provides an important carrier.Welcome entrepreneurs to enter, understand and invest in Yan'an.Will persist“Do it right away, do it well "Service tenet, make every effort to extendVenture capitalProvide the most preferential policies, the most convenient conditions, and the best quality services, create a first-class investment and development environment, so that entrepreneurs can settle down in Yan'an with confidence, peace of mind, and comfort, and work together to writeNew eraA new chapter of joint prosperity and development between enterprises and local governments.
Energy storage
At the promotion meeting, Yan'an Energy Storage ValleydevelopmentThe person in charge of the company introduced the energy storage industry project. The energy storage experts from universities interpreted the development status and future trend of the energy storage industry, and some invited enterprise representatives made speeches.Under the witness of the guests attending the promotion meeting, Yan'an High tech Zone signed 6 projects on site,total investment10 billion yuan.[2-4]
The Blue Book of New Power System Development released on June 2, 2023 proposes to give full play to the advantages of power storage, heat storage, gas storage, cold storage, hydrogen storage, and realize the organic combination and optimization of various types of energy storage in the power systemfunction[10]。
All vanadium flow battery, is a kind of vanadium ionValence stateChange, implementationchemical energyThe large-scale energy storage battery that converts to and from electric energy to store and release the force generated by wind or solar energy is known as "power bank" in the industry.USA, Japan, etcdeveloped countryPower plant peak shaving and wind energy storageVanadium batteryThe industry has developed rapidly and the technology has basically matured.[6]Compared with lithium battery, the biggest advantage of all vanadium flow battery is that it does not burn or explode.[7]
Inductor itself is an energy storage element, and its stored electric energy is proportional to its inductance and the square of the current flowing through it: E=L * I * I/2.Since inductance has resistance at room temperature, resistance consumes energy, so manyEnergy storage technologyuseSuperconductor。Inductive energy storageIt is not yet mature, but there are also examples of application in the newspaper.
Capacitor energy storage
Capacitor is also an energy storage element, and its stored electric energy is proportional to the square of its own capacitance and terminal voltage: E=C * U * U/2.Capacitive energy storageEasy to maintain, no needSuperconductor。Another important point of capacitive energy storage is that it can provide instantaneous high power, which is very suitable forLaser,flash lampAnd other applications.
In addition, there are other ways of energy storage, such as mechanical energy storage.
Energy storage is mainly based on the following two points:
Wind power photovoltaic industry
1.Wind powerPhotovoltaic industryThe rapid development of will promote the development of large capacity energy storage industry.Energy storage technologyTo a large extentNew energy power generationOfRandomness、VolatilityProblem, it can realize smooth output of new energy power generation, effectively regulate changes in grid voltage, frequency and phase caused by new energy power generationPhotovoltaic power generationConveniently and reliably connected to the conventional power grid.The future of energy storage batteries should focus on wind power andPhotoelectric industry, especially the wind power industry which has been widely distributed.The wind resources are unstable. In addition, the second half of the night when the wind resources are large is also the valley of electricity consumption. Therefore, although the wind and photovoltaic industries have developed rapidly in recent years, they have been plagued by "grid connection". The application of energy storage technology can help the wind farm output smooth and "fill the valley with peak".
New energy vehicles
2.New energy vehiclesespeciallyelectric vehicleThe sound development of is conducive to the development of power battery energy storage industry.Four ministries and commissionsThe pilot scheme of subsidy policy for private purchase of new energy in five cities was launched, focusing on pure electric and plug-inHybridSubsidies were provided.With the development of electric vehicles, high-efficiency energy storage batteries will gradually replace internal combustion engines.With the gradual decline of battery cost,MaturityThe substitution ability for internal combustion engines will be gradually enhanced with the increasing of the number of engines.
Energy storage technologyIt can be said thatNew energy industryThe core of the revolution.Huge energy storage industrydevelopment potentialIt will inevitably lead to fierce competition in this market.If the policies are in place, China's energy storage industry can quickly grow into an important global influenceEmerging strategic industriesIt will also greatly promote the large-scale development of domestic new energy.
