Hydrogen Natural Gas Comparison
Comparison of Hydrogen and Natural Gas
Hydrogen and natural gas, both of which are energy choices, have unique characteristics and different applications. Try to analyze in detail.
First, energy characteristics
Hydrogen is lightweight and the lightest element in the universe. Its combustion heat is very high, and it can release about\ (142\ times10 ^ {3}\) kilojoules per kilogram of hydrogen combustion, which is more impressive than the combustion heat of natural gas. And the combustion product is only water, and there are no pollutants such as carbon dioxide and sulfide. It is clean and pure, which is very beneficial to environmental protection.
Natural gas, the main component is methane, which is a fossil energy. Although it burns cleaner than traditional energy sources such as coal, it still emits greenhouse gases such as carbon dioxide. Its combustion heat is about\ (33 - 46\ times10 ^ {3}\) kilojoules per cubic meter, which is lower than that of hydrogen.
Second, production and storage
Hydrogen is produced in various ways. It can be obtained by fossil fuel reforming, water electrolysis and biological hydrogen production. However, although the cost of fossil fuel reforming to produce hydrogen is low, it has concerns about carbon dioxide emissions; water electrolysis to produce hydrogen, the product is pure, but the energy consumption is quite high. As for storage, hydrogen requires strict technical requirements because of its small molecule, easy leakage, and high pressure or low temperature conditions.
Natural gas is mostly derived from underground oil and gas reservoirs, and the exploitation technology is mature. It is relatively simple to store and can be compressed or liquefied. The technical difficulty and cost are lower than that of hydrogen storage.
III. Application field
Hydrogen is used in the transportation field. It can be used as fuel cell power to supply energy for automobiles, ships, etc. It has a long battery life and zero emissions, and has broad prospects. It is also indispensable in industrial fields, such as chemical synthesis, metallurgy, etc.
Natural gas is widely used in power generation, heating and civil gas. In the chemical industry, it is an important raw material for the synthesis of many chemical products.
From this perspective, hydrogen is clean and efficient, but the production and storage problems remain to be solved; natural gas technology is mature and widely used, but environmental protection needs to be taken into account. Both have their own shortcomings and lengths, and they should be used according to local conditions and trade-offs to achieve sustainable development of energy.
