Hydrogen – sooner than you think?

February 10, 2022
As we’ve noted before in this blog, there are strong moves to make wider use of hydrogen as a fuel for heating, to replace fossil fuels. Whilst the switch to 100% hydrogen may still be some way off there is every chance that many heating systems will be burning some hydrogen in the very near future.
