Rules:

Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

I’m not sure why you’re getting downvoted, but companies are looking to use hydrogen fuel cells for 18 wheelers for just this reason. They won’t have to stop for gas even on long trips because the energy density is very high and the weight is less.

Here are a few charts about it from the DOE: https://www.energy.gov/eere/fuelcells/articles/fuel-cell-and-battery-electric-vehicles-compared

The downvotes are because almost all of the global hydrogen production is made either with natural gas, as a byproduct of oil drilling or through coal.

In its current state, it is a fake green product pushed by the oil industry to hamper the transition.

Ah - that makes sense, thank you. You’re correct, but I work in the aerospace industry with hydrogen fuel cells and green hydrogen is all I’m familiar with, but I realize now that this was bias on my part.

Is hydrolysis not cost-effective? If we have excess electricity, as in this case, can we not use that to get hydrogen?

On the recent lemmy topic of using up votes and down votes incorrectly.

Literally just stating a verifiable fact, not in support or against the technology, and I get down voted lol.
