The British government continues to invest millions of pounds in
hydrogen heating trials. However, Lord Callanan, parliamentary
under-secretary of state for climate change & corporate
responsibility at the Department for Business, Energy and
Industrial Strategy, has admitted heating homes with green hydrogen
rather than natural gas could be "pretty much
impossible".
His main fear is the UK could not produce the volume of green
hydrogen "at reasonable cost" that would be needed to
replace gas. His comments have come as a blow to those who
have long championed hydrogen as the best option with which to
tackle one of the energy crisis' biggest challenges, home
heating.
Depending on which study you read, domestic heating is
responsible for between 25 and 35% of the UK's greenhouse gas
emissions. To put this figure into context, it is 10 times the
aviation industry's emissions.
