A starting point for the production of hydrogen through the reaction of sodium with water

Recently, I posted an article titled “Thoughts on Using On-board Equipment That Produces Hydrogen Cyclically from Sodium Hydroxide and Water to Overcome the Bottlenecks in Hydrogen Fuel Cell Vehicles” on this website, in the hope of sparking further discussion. I thank all the friends who have participated; whether with encouragement or criticism, I consider their involvement to be a sign of concern for this issue. I have also consulted several real-world scholars and industry professionals on this issue, and their view is that it is not a matter of technology or cost, but rather a social issue. Because sodium is a **hazardous chemical that is subject to controlled management, widespread use of sodium could lead to its unauthorized loss and cause social security issues. At first, I wanted to create a system in which sodium is produced through electrolysis using sodium hydroxide; hydrogen is then generated by reacting sodium with water, and this hydrogen is used as an energy source in fuel cells to generate electricity. Some of this electricity is used to power cars, while another portion is used for the electrolytic recovery of sodium hydroxide. But when I thought about it, I laughed – wouldn’t that make it a perpetual motion machine? In fact, the electricity generated from hydrogen produced using sodium is far from sufficient to electrolyze sodium hydroxide and recover sodium; therefore, the recovered sodium hydroxide must be used to electrolyze sodium with energy from the power grid. The advantage of this method is that it takes advantage of the fact that sodium hydroxide is used only once and can be reused in a cyclic manner; no other additives or catalysts are required during use, and no harmful substances are generated. Sodium hydroxide can be recovered through electrolysis to obtain sodium, again without the production of any harmful substances. However, since sodium is a controlled hazardous chemical and its use is not permitted freely in society, even if it is technically and cost-wise feasible, approval from **must be obtained first for it to have any prospects. I believe that if one day it is recognized as an effective method to overcome the challenges associated with hydrogen-powered vehicles and electric cars, and if it becomes as widely used as natural gas in households, then carbon dioxide emissions can be reduced, thereby helping to alleviate the greenhouse effect on Earth. This is a major project related to the human living environment, and it is hoped that it will resonate with society. This is the principle of the reaction between sodium and water as I imagine it, along with a schematic diagram of the onboard device.
Publishing articles with overly one-sided logic will only mislead people; “so even though it is feasible from a technical and cost perspective.” First of all, it’s definitely not feasible in terms of cost; what you say makes it seem as though it might be possible someday. “Their concern isn’t about technology or cost; any half-baked pseudo-expert who claims cost isn’t an issue should come up with meaningful data to prove it
Sodium is a **controlled hazardous chemical that cannot be made available to every ordinary car owner; isn’t it wise to recognize this obvious problem? The Hong Kong-Zhuhai-Macao Bridge has been completed and put into use. Suppose that **after some exploration and evaluation, and after engaging many top international engineering firms, the project was not carried out after all. This definitely involves highly specialized challenges such as geology, tides, seawater corrosion, tsunamis, and ocean currents; it’s possible that these challenges could not be overcome, which is why it was not built. There are surely many idiots who, without knowing anything about the matter, dare to claim that none of these are problems; the real problem is that license plates from the Chinese mainland, Macau, and the Three-Body universe cannot be used interchangeably, so there’s no point in building bridges, which is why no such bridges were built
:Curse: Group owner, beat him up. . . . Half for sodium production and half for power generation – do you think it’s a power bank?

It’s something stupid (idiotic); first of all, the law of conservation of energy cannot be violated, and then there are costs and safety considerations. If a power source that uses elemental sodium as an energy source ever comes into existence, it will surely be a fuel cell with sodium as the negative electrode or something similar to a lithium battery; it certainly won’t be a power source that first causes sodium to react with water to produce hydrogen and then burns that hydrogen. The idea mentioned in the original post is typically the kind of thing conceived by idiots who only have basic knowledge of middle school chemistry. This is the same kind of stupid idea as turning water into oil or cars that only use water.
This approach won’t work. If there is any solution, then using enzymes as catalysts to produce hydrogen through hydrolysis in the presence of light is a more reliable method than using sodium to produce hydrogen.
Think about how dangerous it is to produce hydrogen using a metal with such reactive chemical properties – heat keeps accumulating in certain areas and cannot be dissipated; the products of hydrolysis are corrosive. How can safety be ensured? Any approach based on this idea is essentially false advertising
Seeing this reminds me of the C+CO2 → 2CO reaction from middle school – no matter what you do, the energy comes from the initial fuel, and that initial fuel isn’t the right one.

Therefore, another source of energy must be used to recover sodium, as this is the only way to achieve recycling.
