Hi dflynch. Sorry this is a very late reply to your post of Tue 23:27. I thought you would be interested in the link below showing that Linde , the company supplying the hydrogen dispensing gear with the ITM electroliser, ALSO makes PSA systems as well. Why not kill two birds with one stone , I thought,and include your idea for topping up from the grid! www.linde-engineering.com/en/process-plants/adsorption-and-membrane-plants/hydrogen_recovery_and_purification/
In answer to your other point about the percentage of hydrogen that can be added safely in the PRESENT gas network, see the next link

In order to convert the present network to 100% hydrogen see the next.

The next link I found after seeing Way2L8 post Wed 9:06 . While I applaud the company's entrpreneuriel spirit, I think it would be a backward step to continue that Steam Methane Reforming method of hydrogen production . I can understand the attraction to the chemical industry based in the North East, but not for the rest of the country. I know it mentions carbon capture but that is an extra part to be added. Better to avoid carbon in the first place in the sustainable future. Also ,the roll out of a pure hydrogen network needs co ordination country wide rather than a piecemeal effort . All the same , best of luck Leeds.
