SNOOPY
The gas network operators are already discussing subsidies with government for upgrading/modifying the infrastructure. Firstgas indicated that at least 1/3 of their infrastructure would need to be replaced before the introduction of hydrogen at levels greater than 1%. Then there's the cost of modifying customer premises equipment, let alone training, certification etc.
The government are also being asked to subsidise hydrogen refilling stations, and even large trucks. Given the inefficiency of hydrogen generation, storage, and the highly inefficient fuel cells, we will need to produce huge volumes of gas, so the allocation of funds will need to be significant. Consuming vast quantities of water to electrolyse is ironically also likely to be very unpopular amongst environmentalists.
Given these and other issues, I'm just not convinced an accelerated deployment is viable either fiscally or logistically.

Can electrolysis not be done as an on-site, on-demand type thing using electricity and water? Either way I didn't note any additional budget allocated to hydrogen research and engineering, the 'climate emergency' was very much a back seat passenger this year from what I gather.

Yes, although the volume of water and electricity required to produce even small volumes through electrolysis are enormous.
We're all waiting for the government announcement on the climate change report. The Climate Change Commission are due to announce their final recommendations next week. In the mean time, I suspect the government are realising how complicated that the effects of any decision they make will have profound implications, for example if they levy a tax on natural gas, that could cause homes and businesses to disconnect from the existing gas network, thereby severely compromising a possible option for a future hydrogen distribution network.

I dont think it has been as warm as last year here in Christchurch....The frost has killed a couple of my plants

That's what I thought last night as I noticed the cord out to neighbours EV
And suppose they burnt through heaps of coal last night at Huntly
