Global Internet is the need of sustainable development of human society.
Today, human society faces major challenges: climate change, sustainable energy, clean air, clean water, rapid urbanization, population aging, the emergence of new infectious diseases and safe networks.Climate change and sustainable energy are the first major global challenges, and the global energy Internet is designed to address them.
The general route of energy is low carbon, intelligent and terminal energy electrification.
Electric vehicles are not only a means of transportation, but also a carrier of energy and information. Therefore, electric vehicles will play a very active role in the global energy Internet.
Electric vehicles are distributed loads. Wind energy, solar energy and other energy sources in the future are distributed generation methods. How can distributed generation and distributed load be balanced?
Batteries can run both ways.
The battery can absorb the electricity from the grid and then use the battery to power the electric vehicle. When the electric vehicle has surplus electricity and the power grid needs, the electric vehicle battery can also charge the power grid.
I recently studied the basic relationship between energy and information. With batteries, we can achieve sustainable and distributed energy supply and optimize energy allocation.
At present, clean energy is distributed unevenly all over the world. For example, Africa is rich in solar energy and northern Europe is rich in wind energy.
The backbone centralization should be well coordinated with the micro grid, the solitary network and the distributed network, just like the body, the aorta and the small vein should be well coordinated, and the everbright artery should not be good.
These two ultra-high pressure trunk roads are guaranteed, but they should also give full play to the role of micro grid, isolated network and distributed network, and be able to balance by themselves, especially in the context of low carbonization, so as to reduce the burden on the trunk roads.
Low carbonation is not just about carbon capture, but about carbon balance.
What is carbon balance?
In energy production, carbon dioxide is produced and absorbed. Carbon dioxide is two sides. On the one hand, it is waste and harmful, but on the other hand, it is also material.
For example, carbon dioxide is waste material in power plants, but some chemical plants need carbon dioxide as material.
The same is true for hydrogen. In some steel plants and chemical plants, hydrogen is a waste, and coal oil is a waste. But in some places, hydrogen is a treasure, and hydrogen is a fuel.
When hydrogen is combined with carbon dioxide, methane is produced and fuel is produced.
So you have to balance the carbon dioxide and hydrogen produced by energy production with the carbon dioxide and hydrogen produced by energy consumption.
To fundamentally solve the resource constraints and environmental constraints faced by human energy, clean substitution and power substitution are needed.
Electricity is easy to control and transfer, so the terminal USES it.
At the same time, the terminal electricity is also clean, in the home cooking water does not produce gas, is clean.
But when you look at energy, you can't just look at electricity, you have to look at what's behind it.
I think we need to develop smart integrated energy systems.
The so-called comprehensive energy means that electric energy and chemical energy should complement each other, and electric energy and chemical energy can complement each other.
Carbon dioxide and hydrogen are chemical energy. When you have cheap electricity, you can electrolyze water to produce hydrogen. When you need energy, hydrogen can combine with carbon dioxide to produce fuel.
Therefore, the optimal configuration of energy is not only the optimized configuration of electricity, but also the optimized configuration of comprehensive energy.
This needs to be combined with the optimization of chemical engineering when optimizing power system.
That is to develop advanced chemical industry and realize automation, intelligence and digitization.
In terms of energy digitalization and intelligence, I am now developing "energy computers" and "energy Banks".
Like digital computers, energy computers are first digitized, just as before the telephone could only make phone calls, to text, to telegraph, to watch video, to watch movies with disk or with tape. Now after digitization, everything can be done through satellite, so the energy should be digitized and intelligent.
Digital is storage, or "energy bank".
Like Banks, "energy Banks" have a variety of storage media, not just storage batteries, including physical energy storage, energy conversion and other forms of energy storage.
I've recently been working on nanometer scale supercapacitors that can be used as energy stores by a magnetic field.
Banks centralise bits and pieces of money on their books to do big things. Electricity that is now being dumped can also be centralised through "energy Banks", which do not have to be used today or tomorrow.
After digital storage, add an operating system, which, like the computer's operating system, can be optimized.
That's how you optimize the allocation of energy, where you need energy, where you generate energy, all with energy computers.
In my opinion, the healthy and sustainable development of new energy vehicles should follow the following four basic rules:
1. innovation drive: development of different types of new energy vehicles suitable for national conditions, including national vehicles, high-end vehicles, taxis, buses, special vehicles, etc.
2. wheel drive: policy-driven and market-driven.
3. three good: good products, good infrastructure, good business model.
4. Integration of four networks: integration of transportation network, energy network, information network and humanistic network.
