Has the era of energy storage?

Energy storage everywhere in life
Speaking of energy storage, many people think that it is not in the industry that has just developed with the booming development of photovoltaic wind power. In fact, it is not.
Since ancient times, energy storage has been there, but most of the time we have not regarded them as energy storage.

For example, in addition to a weapon, it is actually an energy storage device.
When the ancients pulled the crossbow and hung on the hook, this completed a standard energy storage process. After that, aiming at the target, the trigger was deducted, and the arrow popped up. At this time, the energy release process was completed.

In summer, if you want to freeze 1 ton of water into ice cubes, you need to consume a lot of energy. Therefore, during the ancient winter, people cut the ice cubes of more than ten degrees or even 20 degrees below or even minus, and kept it in large quantities. When the summer heat came, it was actually a kind of energy storage behavior.

The past clocks and the commonly worn robotic watches that people wore decades ago, the process of making clockwork every day is a typical energy storage process.

Today, the frequency of energy storage for ordinary people is higher, at least once a day. At this time, you may have to ask, when did I have energy storage? If you think about it, you only need to charge the phone once, which is essentially performing an energy storage process.
The golden age of energy storage may have arrived!
In summary, energy storage has always been by our side. The reason why everyone frequently hear the word energy storage is because this era no longer allows us to make small troubles on energy storage, and no longer allow us to continue to use in small range, but urgently need large -scale progress!

Thousands of miles of clear sky, the land of Shenzhou's hundreds of millions of light panels emit a huge amount of electricity. Such a large amount of electricity, the power generation area is sometimes incomplete.
At this time, the younger brother of the photovoltaic said that he had always wanted to say, but he had never dared to say: "Hi, Hi, Brother thermal power, Brother Nuclear Power, you two turn off some machines first, take a break, I'll come!"
The thermal power came with a white eyes, and the fist was tight. Nuclear power sneered: "Can I stop when I want to stop!?"

The wind is strong at night, you are sleeping, but the wind turbines across the country, as well as the coastal wind turbines are still turning hard, constantly sending a lot of electricity. However, there are two options at this time. At this time, there are two options:
Either stop turning the wind power blades, that is, to stop the money tree, don’t shake it again;
Either save the emitted electricity and release it during the peak of electricity during the day.
We will of course choose the latter and save energy!
So you see, energy storage is essentially a money -saving can.
Of course, we hope that the bigger the money can be, the better, it is best to be boundless, just as we need to expand the scale of energy storage now and expand it.
At present, there are many types and forms of energy storage, and they can't count them to two hands. Such as pumping energy storage, gravity energy storage, flywheel energy storage, compressed air energy storage, and various chemical battery energy storage, etc.
The efficiency of these energy storage systems is different. When it comes to efficiency, the crossbow mentioned above as an example:
If the ancients used 10 points to complete the energy storage process, or the energy storage of the crossbow consumes 10 points, and when the arrows were shot out, the arrows only carried 7 points, then then We can say that:
The system efficiency of this crossbow is 70%. In the same way, the efficiency of all energy storage systems at the moment is also calculated.
The current forms of energy storage are all open. The scene is so brilliant, so it can be said that the golden age of energy storage may have arrived! Only by seizing the opportunity can we catch up with the trains of the times.
Pay attention to popular science China, followed us to introduce various types of energy storage.
