The future development of utility scale energy storage market is promising

in the past seven years, the electricity scale energy storage market in the United States has developed rapidly. This is because the technical risks and the costs associated with these devices have fallen sharply, and more and more developers have participated in the market, which has become more complex

the final result is that the solar energy + energy storage item Durethan nylon 6 has been successfully used in the oil pan of Porsche Carrera 911 and Daimler trucks, and the mass production of gear box oil pan of Audi s-tronic is competing with the traditional form of power generation. This is a new survey report recently released by Navigant research, a research organization. The theme of the report is "how utility companies use cost-effective solar energy + energy storage strategies to surpass or replace natural gas power plants."

the investigation report shows that the biggest technological breakthrough in energy storage is lithium-ion batteries. Since 2011, the deployment of lithium-ion batteries accounts for 29.4% of the battery energy storage systems other than pumped storage and 70% of the advanced battery capacity. Lithium ion batteries are compact and can store more energy

anissa dehamna, deputy director of Navigant's energy department, said, "we now see that the price of lithium-ion batteries is low and has fallen sharply. More developers have entered this field, which means more competition at a better price." She refers to energy storage equipment that can maintain three to four hours of energy storage time at a time

the reference case in the investigation report predicts that the levelized energy cost of the new combined cycle gas power plant in 2021 will be USD/MWh. In contrast, the price of the power purchase agreement for the solar energy + energy storage project that will be put into operation in 2018 and 2021 is between $30/MWh and $41/MWh, including capacity payment

she said that in the past seven years, the installed capacity of energy storage systems (such as batteries, flywheels and compressed air energy storage) outside the pumped storage project has reached 893.47 million MW of high-capacity lithium-ion power battery project with an annual output of 600million watt hours

three steps for commercialization of energy storage system

commercialization is a process with three steps: conceptualization, technology development and creation of business plan and market. The energy storage system may work conceptually. But there may be some disjunction between the conceptual things and the real things. Dehemner said that technology is the missing link

now we are in the first two stages, although there are still some "restrictions" on the development of business cases to make the automotive interior parts feel at home, there are also exceptions. For example, the Arizona public service department can prove that solar + energy storage projects are cost-effective, and utility companies can avoid installing fossil fuel power generation facilities

in fact, more and more utility companies are turning to solar energy + energy storage projects, especially in the stage of resource collection. The bidding process includes this asset, with the implicit understanding that the power company is obliged to provide reliable services to customers at the most favorable price

the southwest region of the United States does have advantages, because the solar irradiance in this region is very high, and other regions of the United States will benefit in time. This is because the price of hardware such as solar power generation facilities and battery energy storage systems will be reduced. But at present, the southwest of the United States has more advantages than the northeast

solar energy + energy storage project will replace fossil fuel power generation

dehanna said, "The experience of deployment in the southwest of the United States is that solar + energy storage projects can compete with fossil fuel power generation and are cost-effective. Solar + energy storage projects will continue to grow and replace fossil fuel power generation. The main driving force is economics. On the other hand, there is a shortage of water resources, and energy storage systems, wind power and solar power plants do not need water cooling. The next level is construction time: licensing Fewer licenses, fewer projects involved. "

navigant said that the deployment of solar energy + energy storage projects in the electricity scale market in the rough fracture area is feasible, and will be more and more. The goal now is to guide market participants, including regulators
