There is promising research into mixing hydrogen with existing natural gas pipelines at low concentration (<2%). It doesn't leak any more than gas pipes do already and the low concentration prevents embrittlement. And you don't have to go through the horrendous efficiency of a fuel cell, you just burn it with the gas
Burning hydrogen with natural gas without special equipment creates NOx which is 300x worse than CO2 (but released in smaller quantities).
