Surely this is the final nail in the coffin for the silly idea of blending #hydrogen into the #gas network?

We know it's horribly inefficient and because of the lower calorific value of hydrogen, blending at 20% would only decarbonise the gas supplied by about 7%.

But recent network planning in Victoria (which consumes by far the most gas in Australia) shows that blending wouldn't even be possible until at least 2030.

Major works would be needed, with separate issues affecting both the transmission and distribution systems. Total costs are still unknown but are expected to be high.

Network businesses themselves don’t expect blending to be possible until 2030 and wouldn't be ready to transport pure hydrogen until 2050, or maybe 2040 as a "stretch target".

#Electrification is a much better option on all fronts and will likely make significant progress before any blending could even begin in 2030.

And we don't need to blend hydrogen into the gas grid to provide early demand. That's just daft. Australia uses 650,000 tonnes of hydrogen a year for fertilisers and petrochemicals, all made from fossil fuels. How about we start by replacing that with green hydrogen instead?

If it is technically possible, eventually the economic means to do it will be understood.

Are there use cases where hydrogen/gas mixes can fill a need that electrification simply is unable to? Perhaps industrial energy needs for particularly high temperatures that electricity can't meet?
