Green Hydrogen as a Fuel - Indian Companies leading the Green Revolution

Now World’s first Synthetic Diesel from Green hydrogen -project backed by Bill Gates and Jeff Bezos of Amazon

Synthetic Diesel production from Green hydrogen is called e-fuel.
You would be wondering we want to get rid of Diesel , so here comes Green hydrogen.
But why diesel from Green hydrogen ?.
Intersting !
if in the process of Diesel manufacturing from Green hydrogen , carbon dioxide can be captured and used up during the process of manufacturing diesel. such a diesel is called e-fuel.
when e fuel - Diesel is used in existing IC engine it emits same amount of carbon dioxide. so the entire process is carbon neutral.
Will it not be expensive process ? yes it is , but you don’t need to change your existing fleet of diesel vehicles with hydrogen vehicles which is more expensive
