Cost Of Hydrogen Per Kg
On the cost of hydrogen production
Today, if you want to discuss the cost per kilogram of hydrogen production, this is a priority. There are many ways to produce hydrogen, and the cost of each method varies.
One is to produce hydrogen by reforming fossil fuels, which is a common method. It relies on fossil fuels, such as natural gas, coal, etc., to obtain hydrogen through reforming reactions. However, fossil fuel reserves are limited, and the process of extraction is often polluting. Although the technology is mature, the cost is greatly affected by fluctuations in raw material prices. Mining and transporting fossil fuels costs money, and the equipment and energy required for the reforming process are not small. If the price of natural gas rises, the cost per kilogram of hydrogen produced by its reforming will increase.
Second, hydrogen production by water electrolysis. This is the use of electricity to split water into hydrogen and oxygen. If there is a cheap and stable source of electricity, such as surplus electricity from renewable energy generation, the cost may be controllable. However, in most regions, the cost of electricity is still high, and the investment in electrolysis equipment is expensive, and maintenance costs are also required, resulting in a high cost per kilogram of hydrogen.
Third, the method of biological hydrogen production. Although the use of microorganisms to metabolize hydrogen has the advantages of environmental protection and sustainability, the technology is still in the development stage. Microbial culture conditions are harsh, hydrogen production efficiency is low, and large-scale production is difficult, resulting in high production costs per kilogram of hydrogen, making it difficult to compete with the former two for the time being.
Overall, in order to reduce the cost per kilogram of hydrogen production, multiple efforts are required. At the technical level, continue to develop, improve the efficiency of water electrolysis, and break through the bottleneck of biological hydrogen production; at the energy structure, vigorously develop renewable energy and provide cheap electricity; at the policy level, provide support and guide the development of the industry, in order to achieve the ideal cost of hydrogen production and promote the wide application of hydrogen energy.
