Chapter 907 Cheap Energy Storage Battery

If photovoltaic power, wind power, tidal power and other unstable and discontinuous new energy abandonment of wind and electricity are to be fundamentally solved, the way out lies in energy storage.

In this way, the scattered, discontinuous and unstable power can be converted into molecular energy and stored in the energy storage tank.And it can store a large amount of off-peak electricity.Release it during peak hours of electricity consumption.It can not only meet the needs of power grid shaving peaks and filling valleys, but also solve the problem of accommodating new energy sources such as wind power, photovoltaic power, and tidal power.

The stored energy is converted and output into continuous and stable power frequency alternating current, and the grid is naturally willing to accept it.

In fact, many people know that the fundamental solution to new energy abandonment of wind and electricity lies in energy storage.

Energy storage technology is a key node for the future energy system to have flexibility, inclusiveness and balance functions - once electricity is generated, it cannot be stored, and no matter how efficient it is, it is a waste.

But why until now, this problem has not been properly resolved!
In fact, with the development of new energy, domestic energy storage battery projects are also growing rapidly.

In terms of data, in 2020, Rabbit’s energy storage battery market shipments will be 16.2 GW, a year-on-year increase of 71%, of which 6.6 GW of electric energy storage, accounting for 41%.

2019年5月至2020年7月,全球新增发电侧电化学储能项目113个,兔子新增发电侧电化学储能项目59个,增速据世界前列。

It is predicted that the compound growth rate of electrochemical energy storage will remain at about 57% in a conservative scenario, and exceed 70% in an ideal scenario, that is, the total installed capacity of energy storage by 2025 will reach 35.5GW and 55.8GW respectively.

Even if installed at full capacity, it is still difficult to meet the demand. The fundamental reason is that the cost of allocation and storage is too high to meet the demand for "long-term energy storage" of new energy power generation.

"Long-term energy storage" means an ideal situation-the new energy power generation is hung with a "power bank" for 24 hours, and the energy can be stored for next time whenever the weather is good.

But in reality, this is simply impossible.

Because the cost is too high.

According to the current requirements, terms such as "energy storage scale is 10%-15% of the project capacity" and "continuous energy storage duration of 2-3 hours" are also required. The project was completed and connected to the grid simultaneously.

It is just such a requirement that the cost of a wind power project with relatively good wind resources and relatively low cost per unit of electricity will increase by 30%-60% after allocation and storage, while for wind power projects with higher cost per unit of electricity , the cost of electricity per kilowatt-hour is likely to double after allocation and storage.For a large base project with an installed capacity of more than 100 million kilowatts, it may require an additional investment of hundreds of millions in allocation and storage.

And this is only the cost of additional investment if the energy storage scale is 10%-15% of the project capacity.

If you want [long-term energy storage], the cost required is even more exaggerated.

With the support of policies, new energy power generation is only marginally profitable, and if so many energy storage batteries are to be equipped, then there is no need to consider profitability.

This is why new energy power generation has been talked about for so long, but the development speed is not so ideal.

Before [Chaoqun Group] provided more efficient photovoltaic power generation technology, but this did not really solve the problem of new energy power storage difficulties.

But this difficulty has been solved in front of this new structure energy storage battery launched by [Chaoqun Group].

……………………………………………………………………………………………………………………………………… ……

Wu Siyuan was accompanied by a group of important leaders in the photovoltaic industrial park of the Tengger Desert Project.

Their gazes were all fixed on a huge object shaped like a diamond in front of them.

This object is as high as a ten-story building, and various instruments are connected to it, and finally connected to the nearby photovoltaic industrial park.

There are quite a few engineers busy below.

This object is one of the achievements Wu Siyuan brought out from the world of [Tianmo Shentan], a new type of energy storage battery made from the energy stone structure.

Because [Chaoqun Group] already has a lot of related technical reserves in the laboratory, after Wu Siyuan came back to the real world, he took it out directly as a top-secret laboratory, and directly entered the manufacturing process, and finally took it out , that is the result.

"Wu Dong, tell us about the blockbuster product launched by your group. It's so important that even you are dispatched." The leader who said this is a person who is qualified to enter the meeting. He wears gold-rimmed glasses , a pair of elegant style, said with a smile.

Wu Siyuan smiled lightly when he heard the words, and his eyes fell on a middle-aged engineer with an obvious Mediterranean trend.

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 for many years. Its main materials are calcium carbonate, carbon nano-iron tubes, and tin-based. Graphite particles were added to meet the new structural adjustment needs."

"Compared with other energy storage batteries on the market, the energy storage battery developed by our group has many advantages, the biggest one of which is low cost. Under large-scale industrial production, the cost per kilogram of battery is only It needs 2-3 yuan, which means that the cost of batteries, which are necessary for the new energy power generation industry, will be greatly reduced. It used to cost hundreds of millions of yuan, but now the cost does not exceed 200 million yuan."

When the middle-aged engineer said this, the leaders present who didn't know the inside story all gasped.

[Superior Group], you are going to heaven!
The cost of the battery that originally cost 1 million yuan, you call it 200 million yuan.

calm down!

calm.

Still have to listen to other aspects of performance.

Leaders from the industrial sector said this in their hearts.

He took the initiative to ask aloud, "How is the performance?"

If the performance is bad?

The leader hadn't thought about what would happen if the performance was not good, and the words of the middle-aged engineer gave him a fatal blow to his heart.

"The performance is still good, the energy density can reach 220-230 watt-hours per kilogram, and the charging and discharging speeds are equivalent to fast."

Energy Density 220-230 Wh/kg... This...

The leader feels that [Chaoqun Group] is going to raise the butcher knife against another industry...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 electricity requirements of large-scale industries. As for the city Electricity is not a problem.”

"What about the life of this energy storage battery?" the leader asked.

No matter how low the cost is, it is useless if the battery life is not enough.
