Then you might want to make that 100%.
The only way you can get a boost with hydrogen is if you collect/create it
offboard. Generating it from water onboard will always consume more
power than it generates. In an ideal world, it will consume exactly as much as it generates, still making it pointless.
And electrolysis isn’t just less than 100% efficient. It’s much less.
Let’s say it’s 20% efficient. Now for the sake of simplicity, let’s say that burning the resulting hydrogen is 100% efficient. This means that
for every 5 units of energy you spend electrolyzing the water, you only get 1 back from burning the hydrogen. It’s a losing proposition.
If you still don’t quite get it, let me propose a financial arrangement with you.
For every $5 you pay me, I’ll give $1 back. We can keep doing this until either you’re broke or you get the point. Whichever happens first.
I apologize if I seem a bit aggressive. I’m about to call it a night, so I’m hitting you a bit harder with the math for good measure.
