How do you turn tap water into hydrogen

Hydrogen production by electrolysis has a history of hundreds of years and is a mature technology. At present, the biggest challenge of hydrogen production by water electrolysis is energy consumption. At present, the comprehensive power consumption of obtaining 1 standard cubic meter of hydrogen is 5.2-6 degrees, so hydrogen production by water electrolysis is the highest cost of ownership hydrogen. Since the main cost of electrolytic water is determined by the price of electricity, the price of electricity is the main factor restricting the development. At present, the best way is to use renewable energy to produce hydrogen, and the electricity that can not be consumed by the grid to produce hydrogen, so that the cost of electricity is very low, and the produced hydrogen is used as energy, and the entire process has no carbon emissions.

The second restricting factor is the cost of equipment, and the cost of large-scale hydrogen electrolysis equipment is also high compared with other methods.

The third factor is the size of the equipment, the maximum size of a single unit that can be manufactured is 1000 cubic meters, which is still too small for energy applications. Large-scale equipment can reduce equipment manufacturing costs.

The other factor is the market application, before hydrogen as an energy source, water electrolysis is only used for special industrial applications, no market support leads to slow progress in technology research and development, and it is difficult to reduce the cost of single manufacturing.

The advantages of hydroelectrolysis are that the technology is mature, the process is simple, the gas is high purity, and it is the only way that can be connected with renewable energy sources to produce hydrogen.
