Reply to comment by AldoLagana in 'Landmark achievement': Rolls-Royce and easyJet hail successful hydrogen jet engine test by Wagamaga

And batteries are made of organic fairies? Don’t forget most electric grids in the US are still powered by coal power plants! Id rather bet on hydrogen tech any day and get over this battery obsession!

It’s not like hydrogen storage requires any precious metals

Coal is 20% of the US overall and falling rapidly, so this is just flat out misleading.

My state currently has 0% of electricity produced by coal. At this very moment the CA grid is currently producing approximately 75% of it energy from renewable (63%) and nuclear (8.5%).

If it helps you sleep at night. Don’t feel guilty driving your obnoxiously fascist Tesla.

I drive a Porsche Cayman S. Nothing in that link disproves what I said, in fact it confirms it.

Here’s a list of coal powered plants you can go visit in your overpriced wagon.

Well you must admit, it's a good looking wagon: https://i.imgur.com/ia2gZ2c.jpg

That's looks kinda like the Panamera and not the Cayman.

Panamera is 4 door, but the design language is similar. It’s extremely similar to the 991 911, though, even sharing a bunch of parts. It’s also teeny tiny in person. Another angle gives a better idea of the proportions:

Ah shit, I was thinking of the Cayenne SUV lol

If it's about point of use variables and if all production, transport, and useage "carbon impact" costs were equal, then hydrogen is great for personal transport. Unfortunately, production and transport aren't equal. Applications like jet fuel where hydrogen is part of a controlled reaction for thrust are way different that hydrogen applications in vehicles where hydrogen is part of the electrical discharge process to power electrical batteries that then deliver energy for motors. In the EV Vs Hydrogen dialogues online most people seem to think that hydrogen cars and busses are "burning" hydrogen and that is not the case.

Elon fanboys got their crotch less panties in a bunch. I said it before and I’ll say it again, fuck EVs. https://www.bloomberg.com/news/articles/2022-10-18/bmw-group-chairman-oliver-zipse-hydrogen-cars-are-still-happening

I also am not a fan of Elon or his business practises or the mismanagement of EV marketing over the past two decades from him and any of the fanboys on that particular side of the playing field. I also, however, have been around long enough to know that each vehicle and each "fuel source" will have its proponents and its naysayers and eventually everything works out to whatever the easiest possible method is for getting something done with the appropriate tool at hand. I think every single one of these should be developed to their extent and the market should decide which one is the easiest thing to work with for the desired outcome and desired cost.
