A few % no problem. Various trials being done including one in SA.There has been talk of introducing a small quantity of hydrogen into the LNG reticulated system.
The idea that we'd reticulate pure hydrogen at the residential level using the existing gas pipes however has a lot of problems with it and I'll be very surprised if it happens. Everything from metal embrittlement through to the very wide flammability range of it makes the idea of people using it in their kitchens at least somewhat concerning. It needs far stricter standards than does natural gas, in a situation where costs tend to be cut and maintenance is hit and miss at best.
It's not impossible we end up with every house having hydrogen piped into it but it's far more complex than just changing what's put into the existing gas pipes and adjusting burners. It's not like the change from town gas to natural gas for example which was relatively straightforward.
Different for industry etc obviously.
