Just as he found a place to sit down, he didn't notice that someone was walking towards him.

"Hi, Shang Yiyun, it's not surprising to see me here. ”

At this time, Shang Yiyun suddenly heard a familiar voice, turned around and saw a familiar figure, he didn't expect to meet Qin Liyue here.

If he also knew in his heart that since the other party had come here, he must have come to participate in this exchange meeting.

However, Shang Yiyun thought about it and found that he had met Qin Liyue a lot during this time, and the two also had some fate.

"What's so surprising about this, it's just a little surprised, I really didn't expect to meet you here before I came, but what if I met you, now, the two of us don't have any special relationship, and we don't have any common topics. ”

At this time, Qin Liyue was also helpless when she heard Shang Yiyun's words, because she knew that what Shang Yiyun said was the truth.

And after getting along for such a long time, she also has a deeper understanding of Shang Yiyun, and it is precisely because of this understanding that she feels helpless.

Because in Shang Yiyun's eyes, except for Chen Feiyun, he will have a respectful attitude towards other girls.

Whether it is in daily life or study, this attitude can be reflected.

The two of you ask and I answer, I ask and you answer, fell into an awkward chat, and in the end there was really nothing to say, Qin Liyue found a place not far away and sat down.

In the next time, Shang Yiyun sat in his position and began to wait for the exchange meeting to officially start.

Looking at the people coming in and out of the door, time passed minute by minute, and the exchange meeting between the two schools was about to begin.

Now the two schools are elite, and they are all some cutting-edge in the field of new energy.

The people from the two schools sat on either side, separated by an aisle in the middle, so there was no problem with the position Shang Yiyun was sitting in now.

After the exchange meeting officially began, the leaders of the two schools first gave speeches, the content of which was long and boring, and he even felt sleepy after listening to it for a while.

However, he still cheered up and continued to listen to the leader's speech, and the speech was finally over, and the next time was their stage.

Hydrogen energy technology research belongs to engineering, which is not a good thing for Kyoto University, because Kyoto University is stronger in science, and as for engineering, it is slightly weaker than Huaqing University.

As we all know, Huaqing University is famous for its engineering studies, so Huaqing University's engineering strength is stronger than that of Kyoto University.

But with the variable of Shangyi Cloud, it is not certain who will overpower whom.

The exchange meeting between the two universities is to show their strength, although this exchange meeting is an exchange, but it is also a kind of secret confrontation.

Naturally, this kind of exchange will not be like a random argument in the vegetable market, but let the speaker speak his opinion on the podium and then let others refute it.

After understanding the rules, a student from Huaqing University walked up to the podium, introduced himself, and then began to explain his opinion.

After listening to the other party for a while, Shang Yiyun found that the level of the person who was giving a speech was still good, and it was right to think about it, how could he come here if he didn't have the ability.

The student from Huaqing University started from the development prospect of hydrogen energy and combined his knowledge to give a speech.

"Hydrogen is the most widely distributed substance in the universe, it makes up 75% of the mass of the universe, so hydrogen energy is called the ultimate energy source for mankind. Water is a huge "storehouse" of hydrogen, and if all the hydrogen in seawater were extracted, it would be 9,000 times more calorie than all fossil fuels on the planet.

Hydrogen combustion efficiency is very high, as long as 4% hydrogen is added to gasoline, the internal combustion engine can save 40% of fuel. Millican has clearly proposed a hydrogen plan, announcing that it will allocate 1.7 billion yuan over the next four years to support hydrogen energy development. By 2040, Milliken plans to reduce its use of 11 million barrels of oil per day, which is exactly how much Millican imports per day.

Hydrogen energy is produced through the reaction of hydrogen and oxygen. Hydrogen energy is the chemical energy of hydrogen, which occurs mainly in the form of chemical compounds on the earth and is the most widely distributed substance in the universe, which constitutes 75% of the mass of the universe.

Since hydrogen must be produced from hydrogen-containing substances such as water and fossil fuels, it is a secondary energy source. There are many ways to produce hydrogen in industry, such as water electrolysis, coal gasification to produce hydrogen, heavy oil and natural gas steam catalytic conversion to produce hydrogen, etc.

I think the future of hydrogen has great potential......"

"This concludes my remarks, and I welcome your comments. ”

After saying this, the student of Huaqing University stepped off the rostrum and returned to his position.

At this time, there was a sound of discussion under the rostrum, and they were all talking with the people next to them.

Shang Yiyun did not participate in the discussion, but thought alone, and he also agreed with the previous speech of the Huaqing University student, and his next research goal is hydrogen energy, but it is not clear when the research will be carried out.

After the students of Huaqing University stepped down from the podium and talked for a while, several students from Kyoto University expressed their opinions, which was also a supplement, and then the students from Kyoto University gave speeches.

The student of Kyoto University who walked on the podium, Shang Yiyun knew, because this student was also a celebrity of Kyoto University.

After the other party walked to the podium, like the previous students, he introduced himself first, and then began to talk about his knowledge of obtaining the total price.

As for the theme of the story, it is an explanation of the development of the hydrogen energy industry, and everyone tells a different content, and they are all the content sections that they think they understand the most.

"Hydrogen energy is regarded as the most promising clean energy in the 21st century, and human beings have been interested in hydrogen energy applications since 200 years ago, and since the 70s of the 20th century, hydrogen energy research has been widely carried out in many countries and regions around the world. ”

"As early as 1970, the technical research center of Milliken General Motors proposed the concept of 'hydrogen economy', and in 1976, the Milliken Stanford Research Institute carried out a feasibility study on the hydrogen economy, and since the mid-90s of the 20th century, the confluence of multiple factors has increased the attractiveness of the hydrogen economy. ”

"These factors include: persistent urban air pollution, the need for lower or zero-emission vehicles, the need to reduce foreign oil imports, CO2 emissions and global climate change, the need to store renewable electricity supplies, etc. As a clean, efficient, safe and sustainable new energy, hydrogen energy is regarded as the most promising clean energy in the 21st century and is the strategic energy development direction of mankind. ”

Through the amplification of the speaker, the sound of speech reaches everyone's ears.

Several professors heard these words with satisfied expressions on their faces.

On the podium, the Kyoto University student's talk was not over, and he just mentioned the research on hydrogen energy in Millican, but how could China, as a major country in the world, not have this kind of research.

"The research and development of hydrogen energy in China can be traced back to the early 60s of the 20th century, and Chinese scientists have carried out a lot of effective work on the production of liquid hydrogen as rocket fuel and the research and development of H2/O2 fuel cells in order to develop the country's aerospace industry. The development of hydrogen as an energy carrier and new energy systems began in the 70s of the 20th century. ”

"Hydrogen fuel cell technology has always been considered to be the ultimate solution to the future human energy crisis using hydrogen energy. Shanghai has always been an important base for the R&D and application of hydrogen fuel cells in China, including SAIC, Shanghai Shenli, Tongji University and other enterprises and universities, which have also been engaged in the research and development of hydrogen fuel cells and hydrogen vehicles. With the rapid development of China's economy, the automobile industry has become one of the pillar industries of China. In 2007, Huaguo has become the world's third largest automobile producer and the second largest automobile market. At the same time, the fuel consumption of automobiles has also reached 80 million tons, accounting for about 1/4 of China's total oil demand. In today's increasingly tight energy supply, the development of new energy vehicles is imminent. Using hydrogen as a fuel for a car is undoubtedly the best option. ”

"Although the key technology of fuel cell engine has basically been broken through, it is still necessary to further improve and upgrade the fuel cell industrialization technology to make the industrialization technology mature. At this stage, the state needs to increase investment in research and development to ensure the level and leading edge of Huaguo in the key technology of fuel cell engines. ”

"The state should accelerate the support for the localization and mass production of key raw materials and components of fuel cells, continuously integrate the advantages of fuel cells in all aspects, and promote the extension of the fuel cell industry chain. At the same time, the government should also provide relevant demonstration application supporting facilities, and support the cultivation of fuel cell related industrial chains, so as to accelerate the formulation of regulations and standards related to the demonstration operation of fuel cell vehicles and the construction of supporting facilities such as hydrogen refueling stations, and promote the demonstration operation of fuel cell vehicles carrying passengers. With the strong support of the state, hydrogen energy vehicles will surely become a sunrise industry. ”

......

"This concludes my speech, and if you disagree with anything, you can raise it now. ”

After saying this, he went down and returned to his place.

There were only 12 students who participated in the exchange meetings of the two universities, so even if they gave their own speeches one by one, there was enough time.

Soon, the host called out Shang Yiyun's name, and it was time for him to give a speech.

When Shang Yiyun walked to the podium, several professors sitting in the first row were discussing, and the professors of Huaqing University did not expect that Shang Yiyun would participate in this exchange meeting.

For Shang Yi Yun, several professors from Huaqing University are also more familiar, after all, they also pay attention to some of the more outstanding students in the two universities, so they naturally have a better understanding of Shang Yi Yun's achievements.

"Lao Yang, it's really despicable that you let Shang Yiyun participate in this exchange meeting. ”

At this time, a professor at Huaqing University suddenly said, full of helplessness.

"Hehe, Shang Yiyun, a student from our school, is still a freshman student, so he is naturally qualified to participate in this exchange meeting, who let you be such an excellent student in the school?"

A professor at Kyoto University had a look on his face that he was still selling well.

For these things, Shang Yiyun naturally didn't know, at this time he was on the rostrum, thinking about what to say?

Suddenly, he remembered some knowledge and started his own speech, and what he wanted to talk about was the development and utilization of hydrogen energy.

"There are many aspects of hydrogen energy utilization, some have been realized, and some people are trying to pursue it, in order to achieve the goal of clean new energy, the use of hydrogen will fill all aspects of human life. ”

"At present, the main application of hydrogen energy is hydrogen power generation, and some large power stations, whether hydropower, thermal power or nuclear power, send the generated electricity to the grid, and the grid will transmit it to users. However, the load of various electricity users is different, the power grid is sometimes peak, sometimes it is the trough, in order to regulate the peak load, the power grid often needs to start fast and more flexible power stations, hydrogen power generation is the most suitable to play this role, the use of hydrogen and oxygen combustion, the formation of hydrogen and oxygen generator sets. ”

"This kind of unit is a rocket-type internal combustion engine with a generator, it does not need a complex steam boiler system, so the structure is simple, the maintenance is convenient, the start is rapid, to open that is, to stop that is; when the power grid is low, it can also absorb excess electricity to electrolyze water, produce hydrogen and oxygen, in order to generate electricity during peak hours, this regulation effect is beneficial to the operation of the grid; in addition, hydrogen and oxygen can also directly change the operation of conventional thermal power generation units, improve the power generation capacity of the power station. ”

"The hydrogen power generation method is hydrogen fuel cells. This is a device that uses hydrogen and oxygen to produce electricity directly through an electrochemical reaction, in other words, it is also a reverse reaction of hydrogen and oxygen produced by a water electrolyzer. ”

"The simple original of the fuel cell is that the chemical energy of the fuel is directly converted into electrical energy, without combustion, the energy conversion efficiency can reach 60%-80%, and the pollution is less, the noise is small, the device can be large or small, very flexible; ”

"Moreover, with the development of hydrogen production technology and the lack of fossil energy, the use of hydrogen energy will sooner or later enter the family, first of all, the developed large cities, it can be like the transmission of city gas, through the hydrogen pipeline to thousands of households; ”

"People's lives rely on a hydrogen pipeline, which can replace gas, heating and even electricity lines, and even the gas station of the car is also eliminated, so a clean and convenient hydrogen energy system will create a comfortable living environment for people and reduce many complicated affairs. ”

The reason why Shang Yiyun will talk about this knowledge is because his next goal is to focus on fuel cells.
