What are the characteristics of hydrogen energy Please briefly summarize

Clean, extensive, does not pollute the environment, and has high thermal efficiency.

However, with the current technology, it is difficult to produce and store.

It is clean and environmentally friendly (the only product produced is water), and there are a wide range of raw materials for production (70% of the earth's area is water), but so far there is no suitable method of production, transportation, and storage.

It is clean and pollution-free, and the only product is water.

There is no pollution, and the heat energy generated by combustion per unit mass is maximum.

1. The most common elements exist in nature.

2. 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.

3. Good combustion performance, fast ignition, wide flammable range when mixed with air, high ignition point and fast combustion speed.

4. Non-toxic, compared with other fuels, hydrogen combustion is the cleanest, and a small amount of hydrogen nitride will not produce pollutants such as carbon monoxide, carbon dioxide, hydrocarbons, lead and dust particles harmful to the environment, 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.

5. 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.

6. It can appear as gaseous, liquid or solid metal hydride, which can adapt to the different requirements of storage, transportation and various application environments.

The advantages of hydrogen energy are numerous:

1. Good combustion performance: fast ignition, wide flammability range when mixed with air, high ignition point and fast combustion speed;

2. It is a new energetic energy source with abundant reserves that does not rely on fossil fuels;

3. High calorific value: Except for nuclear fuel, the calorific value of hydrogen is the highest among all fossil fuels, chemical fuels and biofuels;

4. Less consumption: 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 energy ineffective loss;

5. Non-toxic and non-polluting;

6. Multiple forms: gaseous, liquid or solid metal hydrides, which can adapt to the different requirements of storage, transportation and various application environments;

7. High utilization rate: hydrogen eliminates the noise source of internal combustion engine and the hidden danger of energy pollution, and the utilization rate is high;

8. Convenient transportation: 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 benefits from the whole process benefit to be better than other energy sources;

9. Reduce the greenhouse effect: Hydrogen replaces fossil fuels to minimize the greenhouse effect.

Obviously, hydrogen has many advantages over traditional energy sources: it is cleaner and the only product of combustion is water.

Its energy utilization rate is higher, hydrogen per unit mass produces more energy than other energy sources, and more importantly, its water electrolysis can be used by many chemical methods.

There is no pollution after combustion, and the hot plant of hydrogen is large and the content of hydrogen element in the earth is large.

Renewable, pollution-free, low density and high heat.

1. 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 exploited.

2. Hydrogen energy is recognized as a clean energy source and is emerging as a low-carbon and zero-carbon energy source. In the 21st century, China and the United States, Japan, Canada, the European Union and other countries have formulated a hydrogen energy development plan, and China has made progress in the field of hydrogen energy, and is expected to become one of the leading countries in hydrogen energy technology and application in the near future, and is also internationally recognized as the country most likely to take the lead in realizing the industrialization of hydrogen fuel cells and hydrogen energy vehicles.

Hydrogen energy is a kind of new energy, new energy refers to the energy that has just begun to be developed and utilized or is being actively researched and to be promoted, and hydrogen energy is regarded as the most potential clean energy in the 21st century, human beings have been interested in hydrogen energy application since 200 years before Zen Zhi Jujube, to the 70s of the 20th century, many countries and regions in the world have carried out extensive research on hydrogen energy, so hydrogen energy is a kind of new energy. Readers who want to continue to understand whether hydrogen energy is a new energy source can continue to read.

1. Hydrogen is mainly found on the earth in the form of chemical compounds, which is the most widely distributed substance in the universe, which constitutes 75% of the mass of the universe and is a secondary energy source.

2. Hydrogen energy is likely to become a pivotal energy source on the world energy stage in the 21st century, and hydrogen production, storage, transportation, and application technology will also become the focus of attention in the 21st century.

3. Hydrogen has the characteristics of high calorific value of combustion, which is 3 times that of gasoline, twice that of alcohol, and twice that of coke, and the product of hydrogen combustion is water, which is the cleanest energy in the world, rich in resources and sustainable development.

4. Hydrogen is located at the top of the periodic table, its atomic number is 1, it is a gaseous state at room temperature and pressure, and it can become a liquid state at ultra-low temperature and high pressure.

It's obvious. Hydrogen energy has many advantages over traditional energy sources.

It is cleaner and the product of combustion is only water.

It has a higher energy utilization rate and produces more energy per unit mass of hydrogen than other energy sources.

What's more, it's more widely electrolyzed water can be self-fetched using many chemical methods.

(1) Hydrogen has good combustion performance, fast ignition, wide flammability range when mixed with air, high ignition point and fast combustion speed.

2) Hydrogen itself is non-toxic, compared with other fuels, hydrogen combustion is the cleanest, in addition to the generation of water and a small amount of hydrogen nitride, it will not produce pollutants such as carbon monoxide, carbon dioxide, hydrocarbons, lead and dust particles harmful to the environment, 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.

3) There are many forms of hydrogen energy utilization, which can not only produce heat energy through combustion, generate mechanical work in heat engines, but also be used as energy materials for fuel cells, or converted into solid hydrogen for structural materials. The use of hydrogen instead of coal and oil does not require major modifications to existing technical equipment, and the current internal combustion engine can be used with a slight modification.

4) Hydrogen can appear as gaseous, liquid or solid metal hydride, which can adapt to the different requirements of storage, transportation and various application environments. From the above characteristics, it can be seen that hydrogen is an ideal new energetic energy, but to use hydrogen energy must prepare hydrogen energy and store and transport hydrogen energy, the scale preparation of hydrogen is the basis of hydrogen energy application, the scale storage and transportation of hydrogen is the key to hydrogen energy application, hydrogen fuel cell vehicle is the main way and the best form of hydrogen energy application, only the organic combination of the three aspects can make hydrogen energy quickly towards practical use, at present, domestic and foreign are mainly engaged in the development and research of hydrogen scale preparation and hydrogen scale storage and transportation, and have made certain progress.
