The difference between gray hydrogen, blue hydrogen and green hydrogen

I think the difference between gray hydrogen, blue hydrogen and green hydrogen is:

1. Gray Hydrogen: Hydrogen produced by the combustion of fossil fuels (such as oil, natural gas, coal). , etc.), during the production process, there will be carbon dioxide and other emissions. Currently, the vast majority of hydrogen on the market is gray hydrogen, accounting for approximately 95% of current global hydrogen production.

2. Blue hydrogen: It is produced by steam reforming of methane or autothermal steam reforming of natural gas.

3. Green Hydrogen: This is hydrogen produced using renewable energy (such as solar power, wind power, nuclear power, etc.), such as the electrolysis of water to produce hydrogen through the production of renewable energy. the green hydrogen production process, no AC emissionsrbone at all.

Solar water heaters are below freezing and frozen. As long as the weather is good and the sun shines directly on the solar panel, it can work directly for heating.

Solar energy refers to the energy of thermal radiation from the sun (see the three modes of propagation of thermal energy: radiation). Its main manifestation is often called solar rays. Nowadays, it is typically used to generate electricity or provide energy for water heaters. Since the birth of life on earth, it has relied primarily on thermal radiation energy provided by the sun. Since ancient times, humans have also known how to use sunlight to dry objects and use it as a method of making food, such as crafting. salt and dry the salted fish. With the decline of fossil fuels, solar energy has become ahe significant share of human energy consumption and continues to grow. There are two ways to use solar energy: photothermal conversion and photoelectric conversion. Solar power generation is an emerging renewable energy source. Solar energy in a broad sense also includes wind energy, chemical energy, hydropower, etc. on earth.

Solar energy is generated by the fusion of hydrogen and helium inside the sun to release enormous nuclear energy. This is the energy of solar radiation.

Most of the energy needed by humans comes directly or indirectly from the sun. Plants release oxygen, absorb carbon dioxide and convert solar energy into chemical energy and store it in the plant body through photosynthesis. Fossil fuels such as coal, oil and natural gas are also sources ofprimary energies formed by the evolution of ancient plants and animals buried underground over a long geological period. The energy contained in the earth itself generally refers to the energy related to the thermal energy inside the earth and the energy related to the nuclear reaction.

The energy linked to nuclear reactions is nuclear energy. When the structure of the atomic nucleus changes, it can release a large amount of energy, called nuclear energy, or nuclear energy for short, commonly known as atomic energy. It comes from nuclear fission energy resources when uranium, plutonium, etc. are produced. stored in the earth's crust undergo fission reactions, and nuclear fusion energy resources when deuterium, tritium, lithium, etc. stored in the ocean undergo fusion reactions. These substances release energy when nuclear reactions occur. At presente, the main use of nuclear energy is the production of electricity. In addition, it can also be used as other types of energy sources, heat sources, etc.

Solar energy is the energy generated by the continuous nuclear fusion reaction process inside the sun. The average intensity of solar radiation in Earth's orbit is 1369 W/㎡. The equatorial circumference of the Earth is 40,076 kilometers, so it can be calculated that the energy obtained by the Earth can reach 173,000 TW. The standard maximum intensity at sea level is 1 kW/m2, and the 24-hour average annual radiation intensity at a certain point on the Earth's surface is 0.20 kW/m2, which is equivalent at 102,000 TW of energy.

Although the energy radiated by the sun in the earth's atmosphere is only 2.2 billionth of its total radiation energy, it is already 173,000 TW higher, that is- i.e. energy railluminated by the sun on the Earth. the earth every second is equivalent to 5 million tons of coal, the energy radiated to the earth per second is 499,400,00,000 joules. Wind energy, water energy, ocean temperature difference energy, wave energy, and biomass energy on land all come from the sun, even fossil fuels (such as coal, oil, natural gas, etc.) on earth are basically stored since ancient times; Solar energy, that is, solar energy in the broad sense, covers a very broad area, while solar energy in the narrow sense is limited to the direct conversion of photothermal, photoelectric and photochemical energy of solar radiation.
