Which kind of new energy does hydrogen energy belong to, and what kind of energy is hydrogen energy?

Hydrogen energy vehicle hydrogen energy is a secondary energy source, which is produced by using other energy sources in a certain way, unlike coal, oil and natural gas, which can be extracted directly from the ground and almost completely rely on fossil fuels as an ideal new energy source of energy, it has the following characteristics: l, the lightest weight element. In the standard state, when the density is , it can become a liquid, and if the pressure is increased to hundreds of atmospheres, the liquid hydrogen can become metallic hydrogen.

2. The gas with the best thermal conductivity is 10 times higher than that of most gases. 3. The most prevalent elements exist in nature. It is estimated to make up 75 percent of the mass of the universe, and in addition to the presence of hydrogen in the air, it is stored mainly in the form of a chemical compound in water, which is the most widespread substance on Earth.

It is estimated that if all the hydrogen in seawater were extracted, it would produce 9,000 times more heat than all the fossil fuels on Earth. 4. The calorific value of hydrogen is the highest among all fossil fuels, chemical fuels and biofuels, at 142,351kJ kg, which is three times that of gasoline. 5. Good combustion performance, fast ignition, wide flammable range when mixed with air, and high ignition point and fast combustion speed.

6. Non-toxic, compared with other fuels, hydrogen combustion is the cleanest, and there will be no harmful pollutants such as carbon monoxide, carbon dioxide, hydrocarbons, lead and dust particles in addition to hydrogen nitride, and a small amount of hydrogen nitride will not pollute the environment after proper treatment, and the water generated by combustion can continue to produce hydrogen and be recycled repeatedly. The product water is non-corrosive and non-destructive to the equipment. 7. There are many forms of use.

It can not only produce heat energy through combustion, generate mechanical work in heat engines, but also be used as an energy material for fuel cells, or converted into solid hydrogen for use as a structural material. 8. It can appear as gaseous, liquid or solid metal hydride, which can adapt to the different requirements of storage, transportation and various application environments. 9. Long-distance high-voltage transmission can be canceled and replaced by long-distance and short-distance pipeline hydrogen transportation, which is relatively improved in safety and reduces ineffective energy loss.

10. Hydrogen eliminates the noise source of internal combustion engine and the hidden danger of energy pollution, and the utilization rate is high. 11. Hydrogen can reduce the weight of fuel and increase the payload of the vehicle, which can reduce the transportation cost and consider the total social benefit from the whole process benefit, which is better than other energy sources. 12. Hydrogen substitution of fossil fuels can minimize the greenhouse effect can be found on.

Hydrogen energy is a secondary energy source and is a recognized clean energy source.

Scientists predict that hydrogen has the potential to become an important secondary energy source in the 21st century. Hydrogen has a calorific value of up to 24 times that of gasoline, which is up to 24 times that of gasoline. Liquid hydrogen can produce a high temperature of about 1700 meters when burned, which can be used to cut metal; Hydrogen is used as fuel for gas turbines, both to generate electricity and to produce high-pressure steam for heating.

As a general internal combustion engine fuel or urban gas, it is even more superior. After combustion, hydrogen is reverted to water, which is the raw material for hydrogen production, which can be recycled repeatedly and is a non-polluting energy source.

Hydrogen energy is abundant, with 1,000 grams of hydrogen in every 9,000 grams of water on the earth, which is stable and inexhaustible. It is convenient for storage and transportation, can be bottled and piped, reacts with some active metals, and can also temporarily become solid and easy to handle.

Methods for producing hydrogen from water are pyrolysis, electrolysis, and photolysis. Hydrogen in synthetic ammonia gas, which uses coal or coke as raw materials, is obtained by decomposing water vapor through a red-hot carbon layer. This is a typical pyrolysis method for hydrogen.

In the process of producing caustic soda by electrolysis of table salt, hydrogen is precipitated from the cathode of the electrolyzer. In addition, there is a hydrogen production method for direct electrolysis of water. Another method is to imitate the photolysis of water to produce hydrogen that some natural plants have.

Scientists envision the construction of specialized nuclear power plants to produce hydrogen from water electrolysis. For example, building some man-made islands and building nuclear power plants on man-made islands is economical and safe for electrolysis and cooling water, and away from residential areas. The hydrogen and oxygen produced are transported to the land by gas supply pipelines laid underwater, and then some special underground gas storage depots are dug on land by storing natural gas, and the hydrogen is stored inside.

Hydrogen energy source is a kind of clean energy, it is environmentally friendly, that is, after hydrogen combustion, it is very sufficient, it will not pollute the air, so this is a kind of energy advocated.

Yes

1. Hydrogen energy is a secondary energy source, which is renewable and can be obtained by using other energy sources through a certain method, unlike coal, oil and natural gas that can be directly exploited.

2. Compared with other fuels, hydrogen is the cleanest when burned, and will not produce environmentally harmful pollutants such as carbon monoxide except for generating water and a small amount of hydrogen nitride.

Hydrogen energy is a new source of energy. Hydrogen energy is a secondary energy source, which is produced by using other energy sources in a certain way, unlike coal, oil, and natural gas that can be directly extracted, and hydrogen energy is recognized as a clean energy source, and is emerging as a low-carbon and zero-carbon energy source.

Hydrogen has natural advantages such as zero emissions and easy availability, such as the ability to obtain hydrogen through water electrolysis.

There are three reasons why hydrogen energy is listed as one of the important new energy technologies in China:

First, it can get rid of the shackles of traditional fuel energy and control the autonomy of the energy field;

Second, it can achieve the results of energy conservation and emission reduction more quickly, and achieve the "double carbon" goal as soon as possible;

The third is to overcome the cutting-edge technological difficulties and stand firmly on the commanding heights of technology in the global new energy field.

Hydrogen energy is a secondary energy source. Hydrogen energy is a secondary energy source, it is produced by using other energy sources in a certain way, unlike coal, oil, and natural gas that can be directly exploited.

Advantages of Hydrogen Energy:The need to accelerate hydrogen uptake was highlighted in the world's largest climate change report on August 9, and the need to accelerate hydrogen adoption has never been greater. Natural Sciences ** will.

A warning was issued: global warming in the next 20 years.

Levels are likely to rise above pre-industrial levels, and hydrogen is a potential indicator of the fight against global warming.

China Association for Science and Technology. Chairman Wan Gang.

If wind power and photovoltaic power generation are the leading forces in the current new energy industry, hydrogen energy is the future star of the energy field. Hydrogen energy will become the ultimate goal of changing traditional energy, and the development of hydrogen energy industry is the only way for human energy structure adjustment and industrial structure transformation.

Hydrogen energy is a secondary energy source.

Hydrogen energy is produced by using other energy sources in a certain way, and in the standard state, when the density is , it can become a liquid, and if the pressure is increased to hundreds of atmospheres, liquid hydrogen can become metallic hydrogen.

It has the advantages of lightest weight, best thermal conductivity, universal color, recyclability, ideal calorific value, good combustion performance, non-toxic, many forms of utilization, various forms, low consumption, high utilization rate, convenient transportation, and reduction of greenhouse effect.

Storage of hydrogen energy.

High-pressure gaseous hydrogen storage is the most commonly used hydrogen storage method, and it is also the most mature hydrogen storage technology, where hydrogen is compressed and stored as a gas in cylinders.

It is a widely used, simple and easy way to store hydrogen, with low cost, fast filling and deflation speed, and can be carried out at room temperature. However, its biggest weakness is that the hydrogen storage density per unit mass is only about 1% (mass fraction), which cannot meet the requirements of higher applications.

Therefore, under the premise of satisfying safety, it is necessary to increase the hydrogen storage pressure of the container through the improvement of materials and structures to increase the hydrogen storage density, and at the same time reduce the cost of hydrogen storage, so as to meet the commercial application.

Hydrogen is a new energy source, and no one has praised hydrogen as "the world's clean energy" because its combustion product is only water. More importantly, hydrogen is a storable energy carrier. Advantages of hydrogen new energy.

1. It can be prepared by using widely available water as raw materials.

2. The biggest advantage is that the product of its combustion is water, which does not pollute the environment.

3. The heat released during combustion is more, and the heat released by the shed is about 3 times that of gasoline, alcohol and coke of the same quality.

As an energy source, hydrogen has advantages that other energy sources do not have, and it is widely used. It can be used as a fuel, which can be applied to aerospace, welding and section, aerospace, military, etc.; According to its reducibility.

It can also be used for smelting certain metal materials.

2. High calorific value of combustion: hydrogen combustion emits more heat, so the energy utilization rate is higher;

3. The product is pollution-free: water is generated after hydrogen combustion, so that there are no other products and no pollution to the environment.

The calorific value is very high, and it can be used as a new energy source by virtue of this advantage.

When it is put into the air, it reacts with oxygen, and only water and oxygen are produced.

New energy hydrogen fuel is battery technology.

Hydrogen energy is regarded as the most promising clean energy in the 21st century, and is emerging as a low-carbon and zero-carbon energy source.

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. The state should also accelerate the support for the localization and mass production of key raw materials and components for fuel cells, continuously integrate the advantages of fuel cells in all aspects, and promote the extension of the fuel cell industry chain.

How it works

A fuel cell is an energy conversion device, which converts the electrochemical energy of the fuel into electrical energy, which is similar to a battery and is also an electrochemical power generation device, so it is called a fuel cell. The corresponding fuel cell that uses hydrogen as fuel is a hydrogen fuel cell. It can be understood as the reverse reaction of water electrolysis into hydrogen and oxygen.

As a result, the reaction process is both clean and efficient.

Hydrogen fuel cells work by breaking hydrogen into electrons and hydrogen ions (protons) through a catalyst (platinum) in the cathode of the fuel cell. In which protons pass through the proton exchange membrane to reach the negative electrode and react with oxygen, the finch turns into water and heat. The corresponding electrons flow from the positive electrode to the negative electrode through the external circuit to generate electrical energy.

As a new type of energy source, hydrogen energy is one of the research fields that has attracted much attention in recent years. Compared with traditional fossil energy, hydrogen energy is more environmentally friendly and cleaner, so it is considered to be one of the development directions of new energy in the future.

First of all, hydrogen energy can be produced through renewable energy sources such as hydropower and solar energy, which will cause pollution and waste of resources compared to traditional fossil energy. At the same time, hydrogen produces only water and carbon dioxide when burned, and emits negligible pollutants compared to conventional fuel oil, making it more environmentally friendly.

Secondly, hydrogen energy can be applied to many fields, such as automobiles, power generation, etc., which can solve the energy crisis and environmental problems, and Yuji has a wide range of development prospects. At present, some large automobile manufacturers have begun to develop hydrogen energy vehicles, and many research institutions and enterprises are also promoting the research and development of hydrogen power generation, which shows that hydrogen energy as a new energy source has a wide range of application prospects.

Although there are still some problems in hydrogen energy technology, such as high production costs, storage and transportation difficulties, etc., these problems will be gradually solved with the continuous progress of technology and the expansion of applications. It is foreseeable that hydrogen energy will become one of the important new energy sources in the future and contribute to environmental protection and sustainable development.
