You can't just replace natural gas with hydrogen. Biggest issue is the piping. Here in the Netherlands we have a lot of natural gas infrastructure (it used to be mandated that every house gets a gas pipe for central heating and cooking). We would like to reuse it for hydrogen, but the pipes we have right now would leak horribly. Beyond the issues of containing hydrogen, there is another difference. You can't (easily) liquefy hydrogen, whereas liquefied natural gas (LNG) is a big thing.
