Black technology starts from the steel suit

Chapter 101 Chapter 101 Discussion about the Future

"Everyone knows that supercapacitors are a very popular concept, but what is the use of this thing? Why are everyone so excited after a certain technological breakthrough in this project?"

"That's the reason. A series of advantages such as cheap price, large capacity, and long service life make it widely used in the field of large-scale energy storage."

"Everyone knows that wind power, solar power, these green and environmentally friendly power generation methods have been in an embarrassing position. Experts also know that before nuclear fusion, wind power and solar power will be the cleanest and highest quality power. source."

"It's a pity that the lack of energy storage systems prevents green energy from playing its due value."

"Everyone should know that our installed capacity of wind power has been increasing, but it is estimated that no one knows that our installed capacity actually decreased a lot in 17 and 18, and the highest drop even reached 11%, because The cost of wind power and photovoltaics is too high, and the cost of grid regulation is also high, which sometimes cannot be adjusted, resulting in a high rate of wind and solar curtailment.”

"This is caused by the failure of energy storage technology!"

"There may be doubts. Don't we have lithium batteries and lead-acid batteries? Why don't we use these things to build large-scale energy storage power stations?"

"First of all, everyone must consider a cost issue. I still have a say in lithium batteries. I believe everyone should know this. After all, our face is quite recognizable."

"Whether the lithium battery is easy to use or not, I can tell you exactly that, expensive things may not be the best, but they must not be bad."

"But this is not a question of whether it is good or not, but a question of whether it is suitable!"

"The energy density of lithium batteries can reach 250wh~300wh/kg, which is indeed not low; while the energy density of improved lithium batteries has to be doubled, which is better to use; but there is a very real problem : What is the price of a traditional lithium battery?"

"I don't need to ask about improved lithium batteries. Let's not talk about the output. The price of a car battery is hundreds of thousands. Can we accept this cost? Can the wallet bear it?"

"The second question, although we generally don't skimp on funds for infrastructure construction, but at the same time, we have certain requirements for the service life, at least it must be consistent with the life of this wind turbine. ?”

"But at present, the cycle performance of lithium batteries is far from meeting this requirement. A set of batteries will begin to decline significantly in performance after 3 years, and will be scrapped properly after [-] years."

"After spending so much money, one can only be used for 3 to 5 years. Who can afford it?"

"Let me talk about another question related to everyone's wallet. If Guodian Group wants to start building energy storage power stations on a large scale, its funds must not be enough. Everyone knows that our state-owned enterprises generally suffer losses year after year, or The profit is definitely not very high."

"Then what should I do, issue a corporate bond, or directly issue a national bond, do you want to buy it?"

"Of course, considering the credibility of our national government, the country will definitely not let everyone lose money. But for an energy storage power station with a service life of at most 5 years, how to calculate the bond period?"

"The interest rate of bonds with a relatively short maturity is relatively low, and they can't beat the inflation rate at all. Not to mention how much money you buy, even capital preservation is a problem!"

"So whether it is for the country or for us, we need to consider this practical issue!"

"As it happens, supercapacitors make up for this deficiency. Although it does not have the high energy density of lithium batteries, it is cheaper and has a longer service life."

"Once the problem of energy storage is solved, the utilization rate of thermal power plants will increase, and a large number of wind power projects will be launched to reduce pollution and waste."

"As you can imagine, once we can solve the problem of large-scale energy storage, the peak load of wind power and photovoltaic power generation on grid equipment will be greatly reduced, which can effectively reduce the cost of maintaining equipment and reduce the cost of grid regulation. Effective use of wind power and photovoltaic power generation can even replace the status of some regulated thermal power stations, effectively reducing the operating cost of our power system!"

"At that time, we can probably imagine that the electricity has been reduced to fifty cents, or even forty-five cents!"

"Of course, you may not care about this dime difference, but you must know that if our industrial electricity consumption, or even commercial electricity consumption, can be reduced by one or two cents, it will undoubtedly be an injection for the manufacturing industry. A shot in the arm can give our industry a second spring.”

"So, right now it's not about supercapacitors, but about the future!"

"Imagine building countless steel monster-like wind power plants on China's [-]-kilometer coastline, facing the wind blowing from the Pacific Ocean, and providing clean and low-cost green energy to the mainland. Wouldn't it make people Excited?"

"And we still have vast and lush land in the north that is not suitable for farming. The cold wind from Siberia brings wind and sand, as well as rain and snow, but it also brings wind energy!"

"When the scale of our wind power and photovoltaic power generation reaches a certain level, we can shut down a large number of thermal power plants, reduce our dependence on external energy, and never have to look at the faces of those foreigners!"

"If you can, who wants to spend money and depend on other people's faces?"

"And just imagine, when we wake up in the morning, we don't have to see the gray sky anymore, we don't have to see the morning smog in winter, we don't have to see the yellow sand in the sky in spring, and we don't have to wear it when we go out. wearing a mask..."

"Isn't this a wonderful scene like a science fiction movie?"

"And the key to the future is already in our hands. To be precise, it has been handed over to the country. Everyone just needs to support it silently. I believe this day is not far away!"

Everyone was immersed in the wonderful prospect described by Wang Feng, but there were also some elderly people who were a little worried.

"Professor Wang, we all understand what you said, and we all hope that our children and grandchildren will live in clear water and blue sky, but everyone has to consider a more realistic issue: if we shut down a large number of thermal power stations, or even To promote new energy vehicles, what should workers and enterprises in traditional industries do?"

"The problem of being a friend is very appropriate. I have to admit this." Wang Feng did not avoid this problem: "But it is imperative to adjust our energy structure."

"This is not a question of whether we are willing to do it, but a question of how much time we have to make such adjustments under the globalized competition mechanism!"
