Cheap Hydrogen Production Methods
Cheap hydrogen production
The desire for cheap hydrogen production is related to people's livelihood and national plans, and it is of great significance in this world. At this moment, the energy revolution, hydrogen energy is the leader of clean energy, but its production cost is high, shackles its wide use. Therefore, it is urgent to explore the way of cheap hydrogen production.
First, the method of water electrolysis. Water is the most widespread thing in the world. By electrolysis of water, hydrogen and oxygen can be obtained. In the past, this energy consumption was quite huge, and the cost was difficult to drop. However, today's technology is new, and new electrode materials and high-efficiency electrolysis technology are developed. If advanced solid oxide water electrolysis cells are used, efficiency can be improved and energy consumption can be reduced. And solar energy, wind energy and other renewable energy sources are gradually emerging, and their electricity is inexhaustible. With renewable electricity water supply electrolysis, the cost may be greatly reduced, which is also in line with the idea of green environmental protection.
Second, the method of reforming fossil fuels. Fossil fuels, such as natural gas and coal, are still abundant in reserves. Take natural gas steam reforming as an example, methane and water vapor react under the action of catalysts to obtain hydrogen. This process is mature, but it needs to solve the risk of carbon dioxide emissions. Today, carbon capture and storage technology (CCS) has been developed together, which can collect the carbon dioxide generated by the reaction and bury it deep in the ground to obtain cheap hydrogen and reduce greenhouse gas emissions.
Third, the method of biological hydrogen production. In nature, many microorganisms have the ability to produce hydrogen. Such as photosynthetic bacteria, fermentation bacteria, etc. Organic waste is used as a substrate, and hydrogen can be generated when microorganisms metabolize it. This raw material is easy to obtain, low cost, and difficult to deal with waste. However, the process of biological hydrogen production is complex and greatly affected by environmental factors. If the technical bottleneck can be broken, the conditions can be optimized, or a new way of cheap hydrogen production can be achieved.
To sum up, in order to achieve the purpose of cheap hydrogen production, it is necessary to gather the advantages of many methods, integrate the power of science and technology, and unremitting exploration to obtain the wide application of hydrogen energy, and create a new chapter for the world's energy pattern.
