J Bower,
Ash is a hardwood and burns hot, not as hot as our better hardwoods such as the Box trees and best of all, Iron Bark.
Ash has a low moisture content so will burn green but for best results should dry for 6 months.
Ash is comparable to Stringy Bark in my experience, l must look up their calorific values.

Probably in England demand has exceeded supply.

Hi Paul,

Taken from the link listed below:

" NSW Premier Dominic Perrottet says a hydrogen strategy
unveiled by the NSW government that aims to help the
state hit net zero emissions by 2050 is 'world leading.'"

"The strategy provides up to $3 billion incentives for
green hydrogen production including tax exemptions and
includes plans for a "hydrogen refuelling highway" between
Melbourne and Brisbane."

" Mr Perrottet unveiled the blue-print at a media event
with mining magnet Andrew "twiggy" Forrest in Sydney
(Wednesday morning). The Premier said the plan would create
tens of thousands of jobs and secure NSW as an "energy superpower."

I'm even more impressed with this man!

cont'd ...

Sorry Paul I left out "news" in the link.
Here it is again:

Having read that I am not impressed.

Forrest saving the planet? Spare me, that bloke will be looking to stripe every poor person in Australia. We will pay and he will play. Claim every dollar as tax free and then some. At the end of it will be all sorts of junk lying around for the next fraud to buy up and use to steal from us. There was a big solar array in Bridgewater in Victoria, went broke and equipment taken North for further harvesting of subsidies.
What a joke we are, anyone here read about the "Groundnuts Scheme" or even the "South Sea Bubble". We deserve all we get as a cowardly bunch cowed by loudmouths and spivs!

Truth is no measured in mass appeal.

"All truth passes through three stages. First,
it is ridiculed. Second, it is violently opposed.
Third, it is accepted as being self-evident."
