Dude, where's my fuel?

One thing that is unclear to me - are there items that need to be replaced/regenerated? The article says the costs are mostly capital. If true, on a long enough timeline, are you not just looking at entirely operational costs (sourcing water + electricity)?

Yes, only inputs are air and electricity. If you have an equipment payback of only a few years, then after that all fuel is close to opex only. Similar to solar itself.

The chemical reagents are not consumed in operation, but they could be subject to contamination over time, and need to be replaced periodically.
