Home refueling compressors have been installed in California and other locations for 8 years at least. It isn't new. Granted that doesn't mean a city may add needless code requirements; that wouldn't be a first.
The flow rate is not significant compared to your furnace and stove. would need to research that because most homes now only have 1/2 PSI systems-so compressing 30 gallons of LNG could be a large increase in demand.
It isn't LNG, it is CNG. The fill rate is slow, overnight, not like a commercial unit. 1.2 standard cubic meters per hour or 0.59 cubic feet per minute (atmospheric pressure).

I disagree these are common problems for people who handle this kind of fuels...
I've been a design engineer working commercial and industrial facilities with compressed natural gas and other petroleum and petrochemical facilities for a few decades. This isn't new and untested technology.
