All countries in the world attach great importance to the investment in energy storage. It is estimated that from 2014 to 2020, the size of China's power grid-only energy storage market will exceed 10 billion U.S. dollars.
This is an important conclusion from the All-New Energy Chamber of Commerce and the Hanergy Group recently released "Global New Energy Development Report 2014" (the "Report").
Energy storage applications are mainly focused on renewable energy power generation peak shifting, distributed energy and micro-grid, power auxiliary services, power quality FM, charging and discharging of electric vehicles, etc., is the key to solve the new energy power storage, and thus much investment institutions Favor.
However, under the premise of a large number of technical routes, who can break through in economy and technology, is the key to seize the market.
Domestic market: subject to technology
The report predicts that by 2020, the global annual investment of energy storage market will reach 4.74 billion U.S. dollars, and China's cumulative installed capacity will exceed 300 megawatts.
Take pumped storage power station as an example, China now has built more than 20 seats, accounting for 1.73% of the global total installed capacity. In general, the proportion of pumped storage in industrialized countries is between 5% and 10%. Our country has ample room for development.
China's "Twelfth Five-Year Plan" specifically mentioned that energy storage is to promote the construction of smart grids, urban and rural power grids to strengthen and enhance the optimal allocation of power grid based on technology. The "NPC and CPPCC" in 2014 discussed the magnitude and mode of energy subsidies for energy storage. National Grid in the subsequent introduction of social capital programs, but also the introduction of pumped storage power station.
In general, due to geographical constraints, new energy power generation requires chemical energy storage. However, chemical energy storage technologies have many advantages and disadvantages, and are the current status quo.
Now the main chemical storage technology, including sodium sulfur batteries, lithium batteries, flow batteries, lead-acid batteries, lithium iron phosphate batteries.
A long-time energy storage industry research and development and operations of the industry told the "First Financial Daily" told reporters that many domestic energy storage companies, but the future of technology companies rely on the government's subject fees and subsidies to survive, there is no company Rely on their own power to make money in the market, all companies are advertised advanced technology, but in fact it is difficult to distinguish.
Investors looking for investment in energy storage and new energy sources believe that although the promotion of mid- to long-term electric vehicles will promote the deployment of energy storage technologies, the market will be activated in the short term by technology and power systems. The popularity of the United States Tesla electric vehicles, mainly due to the battery series and control technology, but a far cry from the domestic technology is far from ripe.
State Grid recently made it clear that policies should encourage the construction of charging and replacing electricity piles. However, from the past experience, it is not easy to build electricity charging piles. In particular, there is no differential electricity price between ordinary users. Ordinary users will not build their own charging piles. Considering the rate of return, the price of electricity under current tariff system does not fluctuate widely, and the rate of return is not high.
However, China has always supported the development of electric vehicles. In 2013, it introduced a new subsidy standard for new energy vehicles and subsidized new energy vehicles. Energy storage technologies are also evolving. According to the report, the energy density of EV storage batteries will further increase. The cost will also drop from the current US $ 1,380 / kWh to US $ 415 / kWh in 2015 and will decrease in 2020 To $ 275 / kWh, more and more conducive to the application.
Global Market: Subsidy Driven
According to the "Report" statistics, in 2013, the newly installed capacity of global energy storage excluding pumped storage and ice storage reached 208 MW, and the number of projects increased faster than 2012.
As of March 24, 2014, a total of 335 global energy storage projects have been implemented. The global pattern of energy storage technologies is taking shape. Markets in North America, East Asia and Western Europe are particularly noticeable.
The total global energy storage financing reached 3.8 billion U.S. dollars in 2013, 1.8 times that of 2012. The amount of financing in the United States is 930 million U.S. dollars, accounting for 24.4% of the total global financing amount. The amount of financing in China is 170 million U.S. dollars, accounting for only 4.5%.
Behind the numbers, all countries are supporting the energy storage industry. In European countries, energy storage is generally supported by subsidies. From May 2013, Germany subsidized the storage of PV power plants with a subsidy of US $ 835 / kW for new energy storage devices and US $ 919 / kW for the upgrade of existing energy storage devices. Germany also initiated the energy storage startup fund project to raise 280 million U.S. dollars for investment in energy storage research and development.
UK Since 2013, the government has provided 33.24 million U.S. dollars to independently develop grid-level energy storage technologies. Italy also subsidized energy storage projects. The European Energy Storage Association and the European Energy Research Union released a roadmap for grid-scale energy storage technologies, giving a high-level market design proposal to support the development of the energy storage industry.
Some states in the United States have passed the act requiring utilities companies to complete the purchase and installation of energy storage equipment to promote the R & D and competition of energy storage technologies. Japan provides special subsidies for household and commercial battery energy storage systems.
In technology research and development, the United States is at the forefront of the world. However, the United States generally uses commercial markets in the dynasties and more in California, but its popularity is not good.
