Although this is certainly more sophisticated than earlier efforts it's not exactly a new idea. Experiments on hydrogen-powered piston engines go back least 50 years. (I'll resist the temptation to post a picture of the UCLA hydrogen-powered Gremlin from 1972 again.😉)
Patents are pieces of paper, not real products.
They are used by big corporations to sue each other.
I’ll believe it when I see it. Until then, I will be happily driving my ICE.
Sounds expensive but there's no harm in studying it. Personally, I think EV's a steppingstone to something else. Synthetic gas or hydrogen, etc.
If I can run my gas engine on something for cheap I'm all for it....I just don't see that happening, ever. Aside from that one time it dropped to $1.09/gallon in 2020, oh that was magic. I cruised & cruised until repairs got in the way😄
You can always get one of those U.S. military 2.5 ton trucks which can run on any liquid capable of igniting.
They are giant, diesel & completely lacking any comforts but you can run it on used engine oil, however you'll not only have to filter it a couple times but engine maintainence will be needed even more often.
If diesel parts weren't so expensive & the works alien to me I'd give it a go. Some guys love em & can't get enough, others realize after the first repair if they don't have a giant wallet or lots of experience, it's time to sell. From what I've heard more often than not it'll be sold within two years after purchase.
Hydrogen is a carbon free fuel, so it makes the environmentalists happy. The question is where and how to obtain the hydrogen.
Hydrogen can be obtained from a variety of processes, some more "greener" than others. https://www.weforum.org/agenda/2021/07/clean-energy-green-hydrogen/
Storage of adequate amounts of hydrogen is a challenge, as is transporting it through pipelines. Hydrogen is a sneaky molecule and it leaks very easily, it also causes embrittlement in pipelines and machine components. However, that can be resolved by using the proper materials.
NASA has the largest hydrogen storage facility in the world. It stores enough hydrogen to power a utility grade gas turbine for about 8 hours. We have a long way to go before H2 is used in ICEs on a wide scale.
