Can you recycle hydrogen

Answer 1

No. Hydrogen is too dangerous to be where humans live. A spark will generate a glorious explosion. After explosion, the product is water. You need energy to break up the water molecules to form hydrogen and oxygen gases again; the combination of hydrogen and oxygen is also explosive. The energy to break up the water is probably higher than what you can get from burning hydrogen with oxygen -- I did not do a calculation, but if it is untrue, then we should have been breaking up water molecules and not worry about rising gasoline price. So, recycling hydrogen is possible but impractical.

Answer 2

Yes, hydrogen can be recycled through processes like steam methane reforming, water electrolysis, or biomass gasification. These processes allow hydrogen to be extracted, purified, and reused in various applications such as fuel cells or industrial processes.
