1, the necessity of the development of the global energy storage industry
Since the industrialization, fossil energy supporting the development of human society is facing exhaustion. The long-term environmental problems caused by fossil energy consumption and the related global climate change affect the survival of mankind on the earth, which is a common challenge faced by mankind. In order to solve the contradiction between the expansion of energy demand and the shortage of fossil energy supply, the global energy sector is undergoing profound changes in order to cope with the severe challenges of environmental pollution and warming.
First of all, in the development of energy supply and energy, increase the development and utilization of new energy, gradually replace fossil energy, and promote the transformation of energy development mode. New energy has played an important role in meeting the needs of energy, improving the energy structure and reducing environmental pollution. The proportion of new energy in the energy sector is increasing year by year.
Secondly, promote the transformation of energy supply and distribution, and increase the construction of smart grid. The smart grid, namely "2 power", is based on the traditional power system, through the integration of new energy, new materials, new equipment and advanced sensor technology, information technology, control technology, energy storage technology and other new technologies, a new generation of power system is formed, with high informatization, automation, interactive and other features. Can achieve better network security, reliable, economic and efficient operation.
Finally, the transformation of energy use is realized. The changes in energy use are mainly shown in two aspects: one is to energetically carry out energy saving and emission reduction, and the two is the rise of new energy products.
However, due to the instability and intermittence of new energy generation, large-scale development and utilization will make the contradiction between supply and demand more prominent. The problem of global abandoning and abandoning light is widespread, which seriously restricts the development of new energy. Therefore, the breakthrough and innovation of energy storage technology is the key to the smooth development of new energy and the key to the promotion of energy field.
2, the development status of the global energy storage industry, the energy storage industry as the supporting industry and key driver of the energy structure adjustment, has broad application prospects in the traditional generation, transmission and distribution, power demand side, ancillary services, new energy access and other fields. As an emerging industry, energy storage in 2007 has maintained rapid growth, according to incomplete statistics, the global energy storage project in power system the total installed capacity from 2007 to 2016 the development of the 100MW 1945.1MW (not including pumped storage, compressed air energy storage and heat storage), a compound annual growth rate (CAGR) reached 193%. According to the incomplete statistics of the energy storage alliance project library, the total installed capacity of the global invested energy storage project is 169.2GW as of the third quarter of 2017. Among them, the total installed capacity of pumped storage is the largest, which is 97%, and the total installed capacity of electrochemical energy storage projects is third, 2244.4MW, accounting for 1.3%, which is 15% higher than that of last year. In the third quarter of 2017, the installed scale of the new global investment electrochemical energy storage project was 94.4MW, which increased by 551% compared to the same period, and increased by 50%. From the geographical distribution, the three quarter of 2017, in the new global investment projects, the UK, China and Japan are the top three countries. The three countries of all projects in centralized renewable energy grid and auxiliary services; new construction / planning project, Australia, the United States and the United Kingdom is the installed capacity of the top three countries, the three countries of the project are mainly distributed in the centralized renewable energy grid and auxiliary services, the proportion reached 91%. From the perspective of application distribution, in the third quarter of 2017, the installed capacity of ancillary services in the world is the largest, 31.5MW, the proportion is 33%, an increase of 6200% over the same period, and the growth rate is 75%. The project mainly concentrated in Europe and Britain, Germany and Belgium and other countries such as Britain, Bristol and Darlington FM storage projects, energy storage in Europe to balance the market or independent power plant and gas turbine combined operation mode, provide an FM service.
3. The prospects for the development of the global energy storage industry
The research and development of energy storage technology has been attached importance to by many countries, because in a sense, the degree of application of energy storage technology determines the development level of new energy, and the importance of energy storage industry is obvious. With the decline of photovoltaic FIT, household subsidy, tax credit, energy intelligent network control and other factors, the main energy storage market in the world is booming. With the decreasing cost of energy storage technology and the implementation of the compensation mechanism, it is expected that by 2025, the total installed size of the global electrochemical energy storage project will break through 4000MW. From the predicted data, all walks of life have confidence in the rapid development of the future energy storage market.
