This is something that has drawn my attention. 

Looks like these guys have taken the first step towards getting this tech to the consumer market , unfortunately I could not see any prices ,,

Lets hope for the best , the only problem would be , what to do with the BMV

 

Ancient thread, but interested people may enjoy this https://www.lowtechmagazine.com/compressed-air/

It's an interesting parlor trick, but until they repeal The 2nd Law of Thermodynamics,  it isn't really very energy efficient, and there are engineering & safety issues involved in storing and using that compressed air in traffic....

...but it's still nice to dream.

So if you store the compressed air and also the heat produced it can be efficient enough to to make it commercially viable.. it seems... in theory. When it pops I would not want to be close

But it seems like Europe is moving towards towards splitting water and storing the hydrogen gas to be used in fuel cells and also as combustible fuel.

The japanese have gas cooled nuclear reactors that are able to produce large quantities of hydrogen as a by-product of operations. Might explain why Toyota is not so keen on BEV and would rather develop fuel cells

In December 2017, the company ran out of money.^[2] In December 2017, it cut the workforce down to 15 as it entered "hibernation".^[11] In March 2018, the company closed.^[2] Innovacorp vice-president of investment Charles Baxter cited the emergence of cheaper Lithium-ion batteries in the field of energy storage as the reason for LightSail's failure to commercialize its storage devices.^[2]

Fuel cells are so stupid, no offense, when you look at the total lifecycle efficiency from water -> car moving forward, the efficiency is laughable

Green Hydrogen is a solid concept but ONLY when applied as a direct fuel additive/replacement or base to produce other organics like methanol, ethanol

My opinion is that compressed air is good combined with a combustion engine because it could exploit the heat of the exhaust gases.

I'm a fan of a futuristic hydrogen combustion engine  h2 -> turbogas system(combustion + steam power) -> clean exhaust gases(for a combined compressed air engine)...  It'd can be more performing(power, efficiency)/green than fuel cells...
