I’m just waiting for these companies to admit the same thing about all other forms of “sustainable aviation fuel.” SAF is a joke and distracts from the fact that the travel industry needs to shift to electrified high-speed rail for continental travel and, for intercontinental travel, investigate ways to use wind and solar to make sailing an realistic option.
Admittedly, this makes long journeys longer. But the reality is that the world’s obsession with fast travel is a problem in and of itself. We need to slow down as a society. There’s no way around it.
I don’t how this guy seems to have made a living shitting on hydrogen without ever showing his working out. I guess he saves costs by using AI generation

Let them know. Maybe point out the hypocrisy of telling people to go green and use less energy while they’re using AI generation which is fucking awful for the environment.
Well, the image itself isn’t bad, but I agree they really could have spent that time to get an actual image of an Airbus hydrogen concept plane.
Hydrogen will never catch on until we can figure out the storage problem. It’s hard to store useful amounts of hydrogen in a small space without cryogenics or insane pressures. Fuel cells that generate hydrogen as needed from water or something is probably what we’ll end up with.
It’s easy, really. Base grid load tends to be slow to adjust, like nuclear could take days. Use that extra base load to run electrolysis when it isn’t being used. Grid usage is predictable enough that production would be pretty steady. It is already being stored successfully, and in some places there are even fueling stations for fuel cell cars like the Toyota Mirai.
The fuel is produced ostensibly “for free” and could also be reused in hydrogen turbine peaker plants nearby the nuclear facility when peak needs more peak. For double-free.
We have a new fuel source for a car type that already exists, that has faster refueling times and better range than electric alone, and the fuel cycle is zero carbon.
Fueling stations need to swap tanks, but they can all still exist, so we don’t break a section of the economy at the same time. (The cost to each fueling station would likely be a challenge, in the old days, a government subsidy for conversion would take care of that.)
Suddenly, we’re all on green energy and fossil fuels can suck it. Meanwhile, millions of cars are spewing water exhaust all over instead of pollution, helping with weather/drought cycles at scale.

Oh shit, we’re in now Nazi America, never mind.
The problem with “from water” is that it takes as much energy to separate the hydrogen and oxygen in water as you get back by oxidizing the hydrogen to produce water. You can’t use water as a useful way to store hydrogen for energy because of that.
Also, that’s our drinking water you’re turning into fuel.
Good thing people have been able to use untreated ocean water as the feedstock. It looks like it needs to be scaled up, but the economic advantage should help incentivize that (seawater is free; treated water is expensive!).

Why is a “clean technica” website using AI imagery? Hard to take seriously
https://cleantechnica.com/contact/
Tell them your thoughts.
I really despise how many websites have just started to openly use AI pictures for their featured images. I agree that it’s hard to take seriously. To me: It also says a lot about the values of the websites that use it.
