Zhang: energy storage technology is experiencing explosive growth

Polaris solar PV net news: at the moment, global climate change has a major impact on international energy situation. Renewable energies rise, efficient, clean, low-carbon has become the mainstream of new energy development in the world. But the Intermittency of wind, solar power and control are factors that affect renewable energy, wind power in China has abandoned wind 15~20% rate this year. In addressing the problems of grid-connected renewable energy in the energy storage industry won an important opportunity for the development of the market.

For example, the United States AB2514, California law requires public electricity Board of California (CPUC) starting from March 1, 2012 to determine investor-owned (IOU) power company’s grid in 2015 and 2020 energy targets. This legislation requires the CPUC energy objectives before October 1, 2013, to accept. State-owned power companies have the same requirements. According to this Act established the goal of 1.3 million-kilowatt storage power station. Now you can see in the media: “energy storage time is coming! Are you ready yet? “,” Energy: real impact on future energy pattern of cutting-edge technology “this kind of headline articles.

Both number and size of the project, United States and Japan is still the main energy storage demonstration application countries, global installed capacity share of 40% and 39% respectively. United States is energy storage in the older country, currently has nearly half of the demonstration projects, and there have been a number of commercially available energy storage project. United States in the manufacture of lithium-ion batteries and systems integration applications more often. Coupled with massive government funding. Japan modified by sodium-sulfur batteries, redox flow batteries and lead acid batteries to store energy technologies at the international leading level. After 2011, Fukushima, Japan to promote household energy storage as the focus of industry support. April 2012 introduced subsidies for home energy storage system. In support of this policy, in 2013, increasing energy storage systems get it and put on the market.

EU grid (EEGI) recently published the Atlas of European energy innovation report, 14 European countries energy storage research, development and demonstration projects carried out a statistical analysis. In the past 5 years, these countries public investment and projects directly funded by the European Commission a total of 391, a total investment of EUR 986 million. Germany movements in advancing the energy storage industry is large, planned to invest 50 million euros in 2013 and 2014 for 2 years, subsidies for new energy storage systems directly, 30MW project have now received subsidies. Due to the introduction of the energy subsidy program, and Germany over the next 5 years the storage capacity is expected to reach 2GW˙h.

“Huge solar yield shows Germany will need more solar energy storage batteries, at present there are over 1.4 million photovoltaic plants producing too much power, especially in the time of the noon sun. “Germany Federal Foreign trade and investment agency’s storage expert TobiasRothacher believes that” every Germany newly installed photovoltaic devices, will drive the demand for storage batteries, solar energy storage battery prices will drop significantly in the coming years, this shows that storage battery is a must for the increase, and their prices will become more attractive. ”

EuPD Research institutions under the European market forecasts, Germany for solar battery system sales volume of savings will be increased from 6,000 in 2013 to 2018 more than 100,000, Germany solar savings will burst long battery market in the next three years. Australia mining developed, many industrial and mining areas is an independent power, diesel power, mining, utilities, home storage, and distributed energy market has already begun the overall layout, is expected in 2030 are expected to reach 3000MW. Malaysia, Indonesia and other Southeast Asian countries have become slightly grids in emerging markets. In these areas many of the island, no population, given the island’s geography and economy, micro-grid to be the best solution.

By the end of December 2013, China’s cumulative run total energy storage projects, building and planning more than more than 60, installed capacity exceeds 80MW, including Zhang beichuan country scenery storage transmission and power demonstration project, baoqing energy storing power station reservoir project demonstration project, Ningxia wuzhong Sun mountain scenery, Liaoning Wo Niu Shi wind farm projects, such as all-vanadium redox flow energy storage power station. Among them, distributed generation and micro-grid energy storage projects account for a large proportion, Fushan island scenery wood storage projects, Rudong, Nanji Island micro-grid project, Ali, Tibet solar energy projects, to participate in distributed water and sediment storage and complementary systems, three independent PV smart microgrid projects etc. These demonstration projects implemented both Beijing’s industrial policies encouraging factors, more new energy development and stable market demand on the power grid companies to build an energy storage device. But there is no system in our country’s policy to encourage the development of energy systems, mainly by spontaneous construction enterprise, price policy is also unclear, China’s energy industry faces a triple challenge of the technologies, applications, and market mechanisms.

I joined United States largest multinational power company AES Corporation’s Board of Directors, found in new power plants, they attach great importance to supporting the construction of energy plants. In Chile to build a 200,000-kilowatt power plant 20,000-kilowatt energy storage power station construction, and energy storage power plant investment is often expensive, when they ask me why energy storage power station? They say Chile mine power stability. The company is involved in gas turbine power plant in California to bid, the terms of which was made to complete the construction of 100,000-kilowatt energy storage power station. Electric power enterprises in China when investing in wind power, solar power, there is little to think about building energy storage power station.

At present four important and new energy-related areas, distributed generation and microgrid, support, user side demand response and electric grid energy storage business opportunities and economic system began to emerge. Energy storage industry in China is still in the early stages of development, along with the rapid development of renewable, domestic energy market has great potential, and once started, China will become the world’s largest energy market. Although at this stage it is not related to the storage system and pricing mechanism, but storage is a booming industry, energy and technology sectors has become increasingly subject to the Government’s concern and support, application and demonstration of financial subsidies are gradually advancing.

By the end of 2013, China has run energy projects installed capacity up to 51.5MW in 2012, representing a growth of 39%. Rapid growth related to grid-connected renewable energy, distributed generation and microgrid, electric vehicles and other aspects. In particular the fields of distributed generation and microgrid, Islands with no electricity population the problem solving, build sustainable energy systems, distributed photovoltaic startup, opens up opportunities for energy storage, energy storage application market in China has great potential.

End of 2013, the global total of 40 wind energy projects (including running, building and planning projects), the installed capacity of about 241MW,3/2 projects in Europe and the United States. United States wind energy storage capacity of the largest proportion of European battery energy storage technology and its application in wind farm is in its infancy; China gradually began to develop the wind farm energy demonstration projects. Advanced lithium-ion batteries, lead-acid batteries, redox flow batteries and energy storage in the sodium-sulfur battery is a wind farm application up to four kinds of technology, in terms of quantity, the installed capacity of the project, share more than 80%.

Distributed generation and microgrid is increasingly becoming one of the hotspots in the energy field, according to the national energy plan, by 2020, and distributed power generation capacity will reach 210 million kilowatts, accounting for 11% of the total national installed capacity and energy will be key to distributed generation networks supporting technologies. Energy storage for distributed generation and microgrid mainly to stabilize the system, playing the role of standby power supply and output increase scheduling flexibility of distributed power generation systems. Distributed generation and microgrid projects are mainly used for community, industry, business, users, remote areas, the military and other fields. Among them, the largest number of community classes, representing 50% number of projects, mainly in the United States and Japan. Second class energy storage project is an island and remote areas, total number of items 12% and 9%, respectively, mostly in China and the United States.

United States energy FM projects is the most populous country, more well known projects are energy storage utility, AES New York NY Stephentown20MG 8MG storage power station. Chile FM also carried out energy projects, such as AES Corporation in Chile power grid using three storage projects in the North. China has also begun storing FM station pilot. In September 2013, the first FM-energy storage power station in China Beijing Shijingshan battery energy storage project was officially put into operation.

In North America, Europe and the Asia-Pacific region is to store energy in more areas of the project. United States owns nearly half of the demonstration projects, several installed larger projects were put into operation in 2013, such as AES 40MW FM project is located in the city of Dayton, Maui 10MW wind farm project, making its global installed capacity surpassed Japan, in the first place. European plans to promote renewable energy generation in recent years, Germany and the United Kingdom, and France, and Spain in 2013 and other countries have initiated a number of projects, related to transmission and distribution, Smart City, island micro-grid areas, especially Germany currently 30MW project subsidies. Japan energy storage project installed capacity after the United States, only NGK company more than 300MW of installed capacity.

Fast development of energy projects in China in the past two years, respectively, in grid-connected renewable energy, distributed generation and microgrid deploys in areas such as energy storage and electric vehicle project. From the application point of view, according to the capacity, highest proportion of energy storage in the field of grid-connected renewable energy, 51%, power transmission and distribution, distributed generation and microgrid, and ancillary services is also a main application fields, respectively, and 19% and 16%. Along with China’s energy structure adjustment, energy storage technology market has become a “Blue Ocean”. China’s wind and solar energy “is available everywhere, but it’s not, there are always”. Bottleneck is energy storage, energy storage technology has played a crucial role.

From a technical point of view, as of 2013, highest proportion of sodium-sulfur battery installed still accounted for 45%, followed by lithium-ion batteries and lead acid batteries, 32% and 12% respectively. All-vanadium redox flow batteries are also used in wind power and solar power adjustable reservoir. In 2013, the Chinese energy storage project cumulative installed capacity in 2012 from 47.7MW up to 6,4.9MW, an increase of 36%. As more and more demonstration projects in China, estimated that by 2020, China’s energy market will reach approximately 136.97GW (including pumped storage, Chu Re technologies) 2020 and accounted for 7.6% of the national total power installed capacity 1800GW.

A few days ago, universal Holdings Limited announced in Shanghai, China, through its wholly-owned subsidiary Guan apsun shaped companies and Japan electrical company limited (NEC) set up a joint venture company, NEC to pay $ 100 million to buy A123 companies owned by universal storage system integration Department (A123EnergySolutions), targeting the global energy market. NEC is rivals with universal to buy A123. A123 asset when entering the auction phase, universal faced several competitors are Fortune 500 companies, such as Johnson controls, Siemens and NEC, JCI and NEC to form the joint bid was universal’s biggest competitor. Visible world many companies are bullish on energy storage battery market prospect.

Batteries into battery, start the power supply as well as grid energy storage in three parts. Universal power battery businesses compared to the original goal of universal’s rival bid, Johnson is starting batteries, NEC aims to battery. Electric vehicle businesses in the ascendant in recent years, we need to break through the core technology is the storage battery. Batteries now have a variety of genres, BYD is lithium iron phosphate battery, Tesla is nickel, cobalt, aluminum-lithium-ion battery. Recently Alcoa Canada Corporation and Israel Phinergy company in Montreal to show the mass of aluminum-air batteries, claims may be reduced to 3000 kilometers. At this stage but the aluminum-air battery is irreversible, which is not circulating, but disposable batteries. Mounted on the car for the negative piece of aluminum after the reaction (aluminum hydroxide) was removed, and replaced with new aluminum. Water not only so simple, practical, of course there are many problems to solve.

Renewable energy is the future direction of energy structure adjustment, but only the energy storage problem is solved, we can really move into the era of renewable energy. Real impact on future energy pattern is energy storage technologies, energy storage technology is likely to be the next energy revolution inside the most important direction of breakthrough. If anyone on the storage technology made a major breakthrough, was a great contribution to human development. Now all kinds of storage battery technology emerged, United States after the resignation of former Energy Secretary Steven Chu, the Nobel Prize winner to return to Stanford University research cryptographic lithium batteries. Na sulfur, iron, chromium, vanadium, zinc-air energy storage battery, aluminum and so on endlessly, Tesla electric car claims to their advantage in battery management. Energy storage technology is experiencing explosive growth.
