Why does the Gray & Blue Hydrogen recipes take 1100 seconds, and why does the Hydrolyser has a crafting speed of 500 to compensate, when you can only use the Grey & Blue Hydrogen recipes in the Hydrolyser, and those recipes are all that the Hydrolyser can do?

Also I feel there should be an electric hydrolyser that allow you to use electrolysis to make hydrogen without having to burn fuel.

Electrolysis is made in chemical plants but to make it consume the right amount of energy it has to take a long time to complete but some people get confused by the extremely high power consumption of hydrolyzers without a clear benefit and think it would be better to use chemical plants to make hydrogen, that is the reason I made it so fast, to tell everyone that it's high power consumption comes with a high speed

Nah it's the combination of high speed and very long crafting time that is confusing me.

If the chemical plant and hydrolyser shared the recipes, it would make sense. But they don't.
There's no point when the chemical plant can ONLY do Green Hydrogen, and the Hydrolyser can ONLY do Blue & Grey.

I could understand the hydrolyser's fast crafting speed if the chemical plant also had the long crafting time recipe, but it doesn't.
The Chemical Plant takes 110 second to produce 2 hydrogen.
The hydrolyser takes 2.2 seconds to produce 2 hydrogen, despite its recipe stating that it takes 1100 seconds.

It is especially weird because the Hydrolyser is a burner, so it burns coal & other fuels instead of electricity, and the Chemical Plant require acid and water to make the hydrogen, which further distance them apart, making your argument about people being confused by the hydrolyser's power consumption... confusing.
