Certainly the same disappointment that you have had has happened to me, when ethanol was in fashion as a fuel we were sold the idea that it was a form of clean energy, we know everything that happened afterwards, it turned out to be a fiasco.

If by means of electrolysis I have to generate a great energy expense to obtain hydrogen from water, then it is not so clean and sustainable, because the energy behind it is fossil fuels.

In the end that is why fossil fuel energy is the one that unfortunately continues to dominate the world, because the new energy alternatives are either very expensive or generate a lot of energy.

Greetings friend and thank you for your contribution.
