If we want to fundamentally solve the phenomenon of wind power and wind power abandonment due to unstable and discontinuous new energy sources such as photovoltaic power, wind power, and tidal power, the solution lies in energy storage.
In this way, scattered, discontinuous, and unstable power can be converted into molecular energy and stored in energy storage tanks. It can also store a large amount of low-valley electricity and release it again during peak hours of electricity consumption. This can not only meet the needs of the power grid for peak shaving and valley filling.
, and also solves the problem of consumption of new energy sources such as wind power, photovoltaic power, and tidal power.
The stored energy is converted and output into continuous, stable power frequency alternating current, which the power grid is naturally willing to accept.
In fact, many people know that the fundamental solution to new energy curtailment of wind and power lies in energy storage.
Energy storage technology is a key node for the future energy system to have flexibility, inclusiveness and balance functions - if electricity is generated, it cannot be stored, and no matter how efficient it is, it is still a waste.
But why has this problem not been properly resolved until now?
In fact, with the development of new energy, domestic energy storage battery projects are also growing rapidly.
Speaking from data, in 2020, the Rabbit energy storage battery market shipments were 16.2 GW, a year-on-year increase of 71%, of which electric energy storage was 6.6 GW, accounting for 41%.
From May 2019 to July 2020, there were 113 new electrochemical energy storage projects on the power generation side in the world, and 59 new electrochemical energy storage projects on the power generation side were added in Rabbit. The growth rate is among the highest in the world.
It is predicted that the compound growth rate of electrochemical energy storage will remain at around 57% under conservative scenarios, and will exceed 70% under ideal scenarios, that is, the total installed energy storage capacity will reach 35.5GW and 55.8GW respectively by 2025.
Even if the capacity is installed at full capacity, it is still difficult to meet demand. The fundamental reason is that the cost of distribution and storage is too high and cannot meet the demand for "long-term energy storage" of new energy power generation.
"Long-term energy storage" means an ideal situation - new energy power generation is hung with a "power bank" 24 hours a day, and whenever God is willing, the energy can be stored for next use.
But in reality this is simply not possible.
Because the cost is too high.
According to the current requirements, "energy storage scale is 10%-15% of the project capacity" and "continuous energy storage duration is 2-3 hours" and other terms. It also requires that the energy storage equipment equipped must have peak shaving capabilities and be in line with marketization.
The project was completed and connected to the grid simultaneously.
Just such a requirement will make a wind power project with relatively good wind resources and relatively low kilowatt-hour cost increase by 30% to 60% in cost after distribution and storage, while for wind power projects with higher kilowatt-hour cost.
, the cost of electricity is likely to double after distribution and storage. For a large base project with an installed capacity of more than 1 million kilowatts, it may be necessary to invest hundreds of millions in additional distribution and storage.
And this is only the additional cost required for energy storage scale of 10%-15% of the project capacity.
If you want [long-term energy storage], the cost will be even more exaggerated.
With the support of policies, new energy power generation only makes a small profit, and if so many energy storage batteries are needed, there is no need to consider profitability.
This is also the reason why new energy power generation has been talked about for so long, but the development speed is not so ideal.
Previously [Chaoqun Group] provided more efficient photovoltaic power generation technology, but this did not really solve the problem of difficult new energy power storage.
But this difficulty has been solved with this new structural energy storage battery launched by [Chaoqun Group].

Wu Siyuan was in the photovoltaic industrial park of the Tengger Desert project, accompanied by a group of important leaders.
Their gazes were all fixed on a huge object shaped like a diamond in front of them.
This object is nearly ten stories high, with various instruments connected to it and eventually connected to the nearby photovoltaic industrial park.
There are quite a few engineers busy down below.
This object is one of the achievements Wu Siyuan brought from the world of [Tianmo Shentan], a new energy storage battery made from the energy stone structure.
Because [Chaoqun Group] already had a lot of relevant technical reserves in its laboratory, after Wu Siyuan returned to the real world, he took it out directly under the pretext of a top-secret laboratory, and went directly into manufacturing, and finally took it out
, this is the result.
"Director Wu, please introduce to us the blockbuster product launched by your group. It is so important that you are even involved." The leader who said this was a qualified person to attend meetings. He wore gold-rimmed glasses.
, looked elegant and said with a smile.
Wu Siyuan smiled lightly when he heard this, and his eyes fell on a middle-aged engineer next to him who had obvious Mediterranean trends.
The middle-aged engineer immediately understood.
Wu Siyuan said, "Let's talk about the cost first."
"Okay, Director Wu." The middle-aged engineer cleared his throat, and then said, "This is an energy storage battery developed by our company over many years. Its main materials are calcium carbonate, carbon nanotubes, and tin base.
Graphite particles were added to meet the needs of new structural adjustments."
"Compared with other energy storage batteries on the market, the energy storage battery developed by our group has many advantages. One of the biggest features is its low cost. Under large-scale industrial production, the cost per kilogram of battery is only
It requires 2-3 yuan, which means that the cost of batteries, which are essential for the new energy power generation industry, will drop significantly. It originally cost hundreds of millions of yuan, but now costs no more than 2 million yuan."
When the middle-aged engineer said this, the leaders present who did not know the inside story took a deep breath.
[Super Group], you are going to heaven!
The battery originally cost 100 million yuan, but you paid it 2 million yuan.
calm!
calm.
Still have to listen to other aspects of performance.
Leaders from the industrial sector said this in their hearts.
He took the initiative and asked, "How is the performance?"
What if the performance is not good?
The leader had not thought about what would happen if the performance was not good. The words of the middle-aged engineer gave him another fatal blow to the heart.
"The performance is still good, the energy density can reach 220-230 watt hours per kilogram, and the charging and discharging speeds are very fast."
The energy density is 220-230 watt hours per kilogram...this...
The leader feels that [Chaoqun Group] is going to attack an industry again...not the photovoltaic industry...but the thermal power industry...
Then he heard the middle-aged engineer say, "Its charging speed is 700 kilowatt hours per hour, and it can charge and discharge up to ten channels at the same time. At this level, it can easily meet the power requirements of large industries. As for cities,
Using electricity is no longer a problem."
"What about the lifespan of this energy storage battery?" the leader asked.
If the battery life is not good, it will be useless no matter how low the cost is.
