The global Internet is the need for sustainable development of human society. Today, human society faces major challenges: climate change, sustainable energy, clean air, clean water, rapid urbanization, an aging population, new infectious diseases, and a secure network. Among these major global challenges, climate change and sustainable energy are the first to bear on these two issues. The general route of energy is low carbonization, intelligence and electrification of terminal energy.
Electric vehicles are more than just a means of transportation. Electric vehicles are the carrier of energy and the carrier of information. Therefore, electric vehicles will play a very active role in the global energy Internet. Electric vehicles are distributed loads. Energy sources such as wind and solar energy are distributed in the future. How can distributed power generation be balanced with distributed load? Plus battery can run on both sides. The battery can absorb the electricity of the grid, and then use the battery to power the electric vehicle. When the electric vehicle has surplus electricity, when the power grid needs it, the electric vehicle battery can also charge the grid. I recently studied the basic relationship between energy and information. With a battery, we can achieve a sustainable distributed energy supply and achieve optimal energy allocation.
At present, clean energy is unevenly distributed around the world. For example, Africa is rich in solar energy and Nordic winds are abundant, but the load centers are far away from them, so they need to be connected by UHV. The backbone is centralized, and it must be well coordinated with the micro-grid, the isolated network, and the distributed. Just like the body, the aorta and the small veins should be well matched, and the light aorta is not good. These two, UHV main roads are guarantees, but we must also give full play to the role of micro-grid, isolated network, and distributed, and we can balance ourselves, especially in the low-carbon background, so that we can give the main road. lessen the burden.
Low carbonization is not just carbon capture, but carbon balance. What is carbon balance? Carbon dioxide is produced in energy production and carbon dioxide is also absorbed. Carbon dioxide is two-sided. On the one hand, it is waste and harmful, but on the other hand it is also a material. As an example, carbon dioxide is a waste in power plants, but some chemical plants require carbon dioxide as a material. Hydrogen is also the case. In some steel plants and chemical plants, hydrogen is a waste. Coal-to-oil hydrogen is a waste, but in some places, hydrogen is a treasure, and hydrogen is a fuel. Combining hydrogen with carbon dioxide produces methane and produces fuel. Therefore, it is necessary to balance the carbon dioxide and hydrogen generated in energy production with the carbon dioxide and hydrogen generated in energy consumption.
In order to fundamentally solve the resource constraints and environmental constraints faced by human energy, it is necessary to promote clean substitution and electric energy replacement. The power is easy to control and easy to transport, so the terminal uses it. At the same time, the terminal power is also clean, burning water at home will not produce gas, it is clean.
But when looking at energy, you can’t just see electricity, you have to see things related to electricity behind electricity. I think we need to develop a smart integrated energy system. The so-called integrated energy is to complement the electrical energy and chemical energy, and the electrical energy and chemical energy can complement each other. Just talked about carbon dioxide, hydrogen is chemical energy, when there is very cheap electricity, you can electrolyze water to produce hydrogen. When energy is needed, hydrogen can be combined with carbon dioxide to form fuel. It can also be combined with oxygen to produce fuel cells. Hydrogen itself is also energy. Therefore, the optimal configuration of energy is not only the optimal configuration of electric energy, but the optimal configuration of integrated energy. This requires a combination of optimized chemicals when optimizing the power system. That is to develop advanced chemicals, to achieve automation, intelligence, and digital.
In terms of energy digitization and intelligence, I am currently developing “energy computers” and “energy banks”. The energy computer, like the digital computer, first digitizes the energy, just like the previous telephone can only make calls, to send texts, to telegraph, or to watch videos, watch movies, use disks or belts, and now digitalize through satellites. Everything can be done, so we must digitize and intelligentize energy.
After digitization, it is storage, which is called “energy bank”. “Energy Bank” Like banks, storage media is also diverse, not only storage batteries, but also physical energy storage, energy conversion, etc. are all forms of energy storage. I recently researched micro-nano-scale supercapacitors in series and in parallel, which can be used for energy storage under the action of a magnetic field. The bank collects the scattered pieces of money to do big things. Now the electricity discarded by the wind can be collected through the “energy bank”, and it is not necessary to use it tomorrow.
After the digital storage, an operating system is added, which can be optimized like the operating system of the computer. In this way, the optimal allocation of energy, where energy is needed, and where energy is generated, are all calculated using energy computers.
Let me talk about my views on the healthy development of China’s new energy vehicles.
I believe that the following four basic rules should be followed for the healthy and sustainable development of new energy vehicles:
I. Innovation Drive: Develop different types of new energy vehicles suitable for national conditions, including national cars, high-end cars, taxis, buses, and special vehicles.
Second, two-wheel drive: policy-driven and market-driven.
Good three, three good: good products, good infrastructure, good business model.
Four or four network integration: transportation network, energy network, information network, humanities network integration.
First of all, we must drive innovation and develop different types of cars. China is a populous country. First of all, it must develop a national car. What is a national car? It is a car that everyone can afford, use, use and use reliably. This national car does not need to have the performance of super-running, does not need the performance of Tesla, do not pursue acceleration, sharp turn, because the national car is mainly a means of transportation, so the price is cheaper. I figured it out, a Tesla would need 80 degrees of electricity, and a national car would be 5 kWh. Why? Tesla had to give so much power in pursuit of the acceleration of a few seconds, so it was so big. The battery, the city does not need it, and does not need to run very far. This is a national car.
Then there is the high-end car, which has the same high performance as Tesla but has Chinese characteristics. Then there are special cars, taxis, logistics vehicles, and low-speed cars. Low-speed cars are special markets that are needed in rural areas and towns. Low-speed vehicles do not need state subsidies, but there are hundreds of thousands of possessions in Shandong. Why? In line with the needs of farmers, the market accepts: First, farmers do not need long distance; Second, no high speed is required; The battery can be charged at home, the battery is small, there is no need to charge quickly, and there is no need for a dedicated charging pile. But does it have security issues that need to be improved without quality? Needs, so the government should take care of it. The focus of the low-speed electric vehicle problem is how to solve the road right.
