Hydrogen is tricky gas: it can diffuse into steel making it brittle. In the past the ammonia plants blew up regularly because of this. Although with smaller pressure it shouldn’t be that big of a problem. Gas burners need to be modified or changed to be able to burn efficiently H2. AFAIK now the new gas stoves and heaters can burn a 10% H2 mix with regular gas. Making a fuel cell at home? Probably it wouldn’t be energy efficient compared to just transmitting electricity. But a fuel cell car would be more usable this way.

They started using plastic for natural gas mains in the 60s, the biggest challenge would be in older residences...Code changes are required all the time and people change out appliances frequently.

People do not like the idea of burring gas for purely ideological reasons, there is nothing practical or logical behind the opposition to hydrogen energy.
