#12I wonder if in the time since this was written if anyone has found a good source for small turbo expanders. Liquefied air is a potentially interesting mode of energy storage for islanded solar because it doesn't require high pressure storage (which has safety concerns)-- for that application the round trip efficiency isn't critical as there is nothing else to do with the power... but it can't be a total joke. And the…

The overall quality of this website I'd estimate at least in top 5% of all Web, if not top 1%. The content is superb, the presentation is quite clear.

I turned off my adblocker and I see two inline ads, nothing crazy. Not sure what you’re seeing, but I’m quite sure you should install an adblocker.

If you are dealing with liquid nitrogen from air, then you are probably also dealing with liquid oxygen in the mix. I imaging that at power-storage scales the presence of such amounts of liquid oxygen might create safety issues. Separating it out might nullify any energy storage advantages.

As far as 'closed loop' sadly that does break the economics, I think-- part of the reason why cryogenic nitrogen storage is interesting is because the nitrogen expands 800 fold at atmospheric pressure, so the container for the decompressed nitrogen would be gigantic.

They look like legit AdSense ads, and there's a "liquidnitrogen" comment on one of the related scripts.

It's not all that energetically disfavorable to extract oxygen if you're already compressing the gas. There is a lot of demand for concentrated oxygen too, so one could manufacture it as a side product instead of storing it.

#19The YouTube channel Hyperspace Pirate[0] has been consistently uploading fantastic videos documenting their attempts to make their own homemade liquid nitrogen machine. They don't shy away from including all the technical details, and throw in plenty of hilarious deadpan humor too. Highly recommend them if you're interested in this topic.
