Production of green hydrogen through water electrolysis - how does it work?

Green hydrogen is called the fuel of the future as it has the ability to power the hard to electrify sectors like industry, transportation and buildings,
contributing around 65% of yearly greenhouse gas emission in Europe.

Hydrogen can be produced through a process called water-electrolysis. This process takes place in a unit called an electrolyser. Electrolysers split water into hydrogen and oxygen molecules using electricity, which then provokes a chemical reaction. Direct current at an anode and a cathode splits water into oxygen and hydrogen.

The produced hydrogen is then ready for use in direct application like transport, industry feedstock and steel production.
Indirect, power-to-x applications like, e-fuels, fertilizers, and replacement for natural gas. And lastly grid stabilization and storage.

If the electricity comes from renewable energy sources, such as solar and wind, the hydrogen is completely CO2-free and truly green.

short n crisp video compare to all other videos.
thanks a lot 🤗

How many million tons of vosl will we need to make enough electricity to produce hydrogen for 10 percent of the cars on the road today?

How much water is used for this process? Water is a very valuable commodity. How much energy does it take to produce H2?

Need more electricity to produce hydrogen gas and this very expensive
