Today most of our renewable energy generation costs
It's already lower than the cost of generating electricity for our coal power
So we have a lot of renewable energy generating electricity
At the same time, a large number of global renewable energy projects are constantly evolving
Our renewable energy is inexhaustible in the future
That way, we can make particularly cheap hydrogen
This is a technological breakthrough
In addition to getting hydrogen, how do we use hydrogen, there is a particularly key technology in it, but also in the last three years or so, in almost every coastal city in China, including our Beijing, Zhangjiakou Winter Olympics, are promoting a technology, called what, called hydrogen this fuel cell technology.
This is a speech by Deng Jianqing, the talks speaker, chairman of China Hydrogen Energy Co., Ltd., and vice chairman of the Hydrogen Energy Association of the China Industrial Development Promotion Association.

Where can new energy green hydrogen be used in the future?
Hello everyone, I am Deng Jianqing, a speaker of Moment Talks. I was the founder of China Hydrogen Energy Co., Ltd., and then I was engaged in the development of green hydrogen energy and related technologies.
If we want to get green hydrogen, we must get electricity from renewable energy, and we use the electricity of renewable energy to decompose this hydrogen, then the electricity of this renewable energy is very, very expensive in our previous history. But by 2019, this electricity has been able to compete with the current traditional, thermal power generation price, and today most of our renewable energy generation costs have been lower than the cost of our coal power generation.
So, we have a lot of renewable energy in power generation, while a large number of global renewable energy projects are also constantly developing, our renewable energy, the future is inexhaustible, then in this way, we can make a particularly cheap hydrogen, which is a technological breakthrough. At the same time, we use our traditional military high-tech, that is, our nuclear submarine, we use to produce hydrogen, decompose hydrogen and oxygen called electrolyzer, high-efficiency electrolyzer, can be between four to five degrees of electricity, can decompose a cubic of hydrogen, then in this way, after we have this technology, our hydrogen will be easy and cheap to get.
So in addition to getting hydrogen, how do we use hydrogen, there is a particularly key technology in it, but also in the last three years or so, in almost every coastal city in China, including our Beijing, Zhangjiakou Winter Olympics, are promoting a technology, called what, called hydrogen this fuel cell technology.
This hydrogen fuel cell technology, and the traditional of our power technology is not the same, our traditional power technology, often use what, use the internal combustion engine, and our hydrogen fuel cell technology uses hydrogen electrochemical reaction, it is hydrogen and oxygen in the middle of a proton exchange membrane to generate electricity, and then through this power to drive the motor to form our power. That is to say, our fuel cell technology, it is possible to achieve, like the current Tesla this, is the power battery of such a power output.
But what are its benefits? Its same mass of hydrogen compared with the power battery, its energy density is 100 times that of the energy storage battery of the power battery, that is, our same 1 kg of hydrogen is equivalent to the power battery stored in the 100 kg of power battery, so this technology is very cutting-edge.
So now in our country, we have produced a large number or batch of heavy-duty cars, as well as this bus bus has hydrogen energy, then with these three technologies, the formation of the entire hydrogen energy industry in the future will have 10 trillion green hydrogen emerging markets.
Then these hydrogens will be applied to the transportation of automobile power, aviation power, and marine transportation, will be used in transportation. Well, it's zero-emission that these hydrogens can upend our existing supply of diesel gasoline gas stations and the like. Of course, in addition to our zero-carbon logistics and zero-carbon transportation power, hydrogen also has a very important role, that is, the use of industry just said, we have used nearly 30 million tons of hydrogen in the tradition of industry, but it will also emit billions of tons of carbon dioxide and these pollutants, then we use our green hydrogen and our traditional steelmaking, like this olefin production, like this methanol production, we can use green hydrogen, Go and merge with our traditional coal chemical industry and this petrochemical industry.
Because our coal chemical industry and petrochemical industry, in the process of production, it is to synthesize a new category, what is it called, called hydrogen less carbon more, then hydrogen and a part of the carbon, synthesized new materials, but a lot of carbon dioxide, to the emission. But after we use green hydrogen, we use green hydrogen to synthesize with this carbon that needs to be emitted, and we can make our green hydrogen play a carbon neutral role in the green chemical industry. So in the future, our material world and material world will be applied to hydrogen.
