This article claims that producing hydrogen will remain too expensive
and therefore people will continue to choose to use natural gas if there
isn't an electric alternative. It also mentions the poor efficiency of
producing it.
Using hydrogen fuel risks locking in reliance on fossil fuels,
researchers warn

Fuels produced from hydrogen can be used as straight replacements for
oil and gas and can be low-carbon, if renewable electricity is used to
produce these “e-fuels”. However, the research found that using the
electricity directly to power cars and warm houses was far more
efficient.
...
The analysis estimated that hydrogen-based fuels would be very expensive
and scarce in the coming decade. Therefore, equipment such as
“hydrogen-ready” boilers could end up reliant on fossil gas and continue
to produce the carbon emissions driving global heating.
...
The research, published in the journal Nature Climate Change, calculated
that producing and burning hydrogen-based fuels in home gas boilers
required six to 14 times more electricity than heat pumps providing the
same warmth. This is because energy is wasted in creating the hydrogen,
then the e-fuel, then in burning it. For cars, using e-fuels requires
five times more electricity than is needed than for battery-powered
cars.
...
Daryl Wilson, the executive director of the global, industry-backed
Hydrogen Council, said hydrogen could become the most competitive
low-carbon solution for some sectors by 2030, such as long-haul trucking
and steel.
