Cost of Hydrogen Gas per Kg
On the cost of hydrogen production
In today's world, in the way of energy, hydrogen energy is gradually emerging, which is expected by everyone. However, if you want to use it widely, the cost per kilogram of hydrogen production is really the key, and it depends on whether it can be used smoothly in the world.
There are many ways to produce hydrogen. One is fossil fuel reforming. This way uses natural gas, coal, etc. as sources, and hydrogen is obtained through reforming reactions. Take natural gas as an example, its method is easy to implement, and hydrogen production is quite abundant. However, considering its cost, you need to consider the price of the gas source, the purchase of equipment, and the cost of energy consumption. When the price of gas sources is high, the cost per kilogram of hydrogen also rises. In addition, the energy consumption is not small, so the cost is not light.
The second is water electrolysis. This technique uses electricity to decompose water and generate hydrogen. If electricity is cheap, such as when water is abundant and the price is low, the cost of hydrogen production may be reduced. However, where electricity is expensive, the cost per kilogram of hydrogen is overwhelmed. And the efficiency and lifespan of electrolysis equipment are all related to cost. Efficient and long-lived equipment, although the initial purchase cost is high, may reduce costs in the long run; on the contrary, equipment is often damaged and replaced frequently, and the cost will increase.
The third is biological hydrogen production. This is an emerging method, using microorganisms to metabolize hydrogen production. Most of its sources are biomass, such as agricultural waste, sewage, etc. Although it has the benefits of environmental protection, the technology is not yet mature. Cultivation of bacteria and control of reaction conditions are all difficult problems, and the cost cannot be easily reduced. The manpower and material resources required per kilogram of hydrogen output are also considerable at the moment.
Overall, in order to reduce the cost per kilogram of hydrogen, a multi-pronged approach is required. In terms of technology, strive to improve, develop high-efficiency equipment, optimize reaction processes; in terms of energy, open up new sources, and find cheap and stable electricity or raw materials; in terms of scale, expand production, and reduce unit costs by scale effect. In this way, the cost of hydrogen energy can be close to the people, and it can be used by the world for long-term well-being.
