Hydrogen blending into gas infrastructure is marketed as a bridge solution but is actually a stalling tactic: even at maximum feasible 20% concentration, it only yields 6% emissions reductions, whereas simpler efficiency measures (operating boilers at condensing temperature) achieve greater reductions without capital expense.

“even if you put 20% hydrogen into the gas grid it only gives you 6% reduction in carbon emissions... We get much better than 6% reduction in carbon emissions just by running our boilers at a at at a proper condensing temperature”
