Methane ReSER hydrogen production process
From the perspective of resource utilization and in the long term, hydrogen production from coal gas and natural gas appears to be more promising.
I work in the hydrogen production industry; let me share my views. The methods for hydrogen production have been listed in great detail above. From a cost perspective, among the various common methods for hydrogen production, coal-based hydrogen production is undoubtedly the cheapest; followed by hydrogen production from natural gas, oil, methanol, and water electrolysis. However, coal-based and oil-based hydrogen production processes are lengthy and require large investments, making them suitable for large-scale hydrogen production, such as in the production of ammonia. Hydrogen production by water electrolysis is the simplest and can be miniaturized. Hydrogen production from natural gas is constrained by resource availability, and not every facility has the necessary conditions for this. Currently, natural gas is cheap, but there is a high likelihood that its price will rise in the future as it becomes linked to its calorific value. The operating cost of hydrogen production from methanol is higher than that using coal and natural gas, but the process is shorter, requires less investment, and is more environmentally friendly; it is currently the most widely used method for hydrogen production. It would be even better if hydrogen produced as a by-product could be recovered; for example, the electrolytic hydrogen from chlor-alkali plants, the coke oven gas from coking plants, and the hydrogen generated as a by-product of various chemical reactions – all of these offer incomparable advantages in terms of operating costs and investment requirements. But these are things that can only be encountered by chance; if one has such resources, they must not give them up. If any student has needs related to hydrogen production, hydrogen addition, or exhaust gas recovery, we can discuss them together.
