Energy storage batteries are a necessary condition for the promotion of renewable energy. At present, energy storage batteries have entered the “pervasive period” of widespread use. In 2023, the global new energy storage battery production capacity will reach 30 GW, an increase of 87% over the previous year, and the scale will increase by 10 times within 5 years. The price of lithium batteries has also fallen by 60% within 5 years. The energy storage battery industry is also heavily subsidized by governments of various countries. Even so, reducing greenhouse gas emissions to near zero is still an elusive goal, and there is an urgent need to further improve the supply capacity of energy storage batteries.
The current energy storage battery market is popular with LiFePO4 lithium ion battery. The PowerWall is widely used in home solar energy, the 48V lifepo4 battery are mainly used for some residential and industrial projects. They are able to provide more energy capacity than conventional lead acid battery. The life cycle is at least 6 times longer while price is only 2-3 times. The LiFePO4 cell has become the first option for most of the users.
Energy storage batteries are key to making renewable energy the primary source of electricity. The output of both solar and wind power depends on the weather. To make good use of these sources of energy, people must build a system to store electricity in storage batteries at the right time, and then use the stored electricity in bad weather conditions.
The current energy storage battery market is dominated by China. China is promoting the development of renewable energy nationwide. In 2022, China will newly install 5.6 gigawatts of energy storage batteries, 2.3 times that of 2021, accounting for 34% of the global total, ranking first in the world.Europe, which accounts for 27% of the world’s total, is also building some large-scale energy storage plants. Spanish utility giant Iberdrola Power invested 28 million euros to build a large-scale energy storage plant of 0.05 gigawatts in Ireland in 2022, and it has been put into use.
On the other hand, Japan’s share of the global energy storage battery market is only 2%. The commercialization of energy storage batteries in Japan is long overdue. Japan has a fixed-price system for feed-in electricity tariffs, so demand for storage batteries, which are used to store electricity, has not grown significantly.
In 2030, the world’s new battery storage capacity is expected to reach 87 gigawatts, which is nearly three times that of 2023. It is estimated that from now to 2030, the energy storage battery industry will expand at an average annual rate of 23%. This means that energy storage batteries have finally entered a period of widespread use.
Behind this is the fact that the manufacturing cost of energy storage batteries has dropped significantly, and cost was once the biggest constraint on the development of energy storage batteries. According to the International Energy Agency, the price of lithium-ion battery packs has fallen by 60% in five years to reach $132 per kWh in 2021. In addition, substantial government subsidies also played a role.
On April 20, the U.S. Department of Energy announced that it will provide up to $3 billion in loan guarantees for the installation of rooftop solar power generation devices and storage batteries, thereby encouraging people to install solar panels and energy storage batteries at home, and try to Distributed electricity is collectively controlled and operated. It’s a technology known as a virtual power plant (VPP), which uses storage batteries to adjust power demand that fluctuates by time and region, making electricity usage more rational. In some regions, energy storage batteries have become a key factor in maintaining electricity stability.
In California, a leader in the field of renewable energy in the United States, in July 2022, the electricity supply realized by energy storage batteries exceeded that of nuclear power plants for the first time. During the day, when there is a surplus of renewable energy, electricity is stored in storage batteries. When night comes, the storage battery outputs power for the user to use. Batteries for energy storage are increasingly capable of reducing users’ reliance on fossil fuel generation during times of unreliable electricity.
However, the rate at which energy storage batteries are being installed has not kept pace with the continued introduction of renewable energy. According to the International Energy Agency, by 2030, the world needs a cumulative battery storage capacity of 780 gigawatts, so as to make global greenhouse gas emissions close to zero by 2050. However, it is estimated that by 2030, the global battery storage capacity can only reach about 500 gigawatts, and the gap will continue to be made up by thermal power generation. The main hurdle is that battery installations remain somewhat concentrated in places like the United States, where government subsidies are more generous.
In addition, there are certain risks in the fact that energy storage battery production activities are still concentrated in China. According to the International Energy Agency, China will account for 62% of global lithium battery production capacity in 2022. In the field of vehicle batteries, CATL is the world’s number one. And as the U.S.-China conflict intensifies, the Biden administration is encouraging domestic companies to produce energy storage batteries. In 2022, the United States passed a bill to provide tax incentives for manufacturing energy storage batteries in the United States, which has attracted many new investments from companies. In addition, the EU also encourages local companies to produce energy storage batteries to change the status quo of relying on China in the field of energy storage batteries.
