CSIRO and Hydrogen fuel breakthrough

Yes, but (as all good arguments begin)...
It's a fledgling technology. One more piece in the puzzle towards a 'greener' solution.
I'm not denying where the majority of H2 comes from these days, but going upstream to find the carbon footprint could be said of pretty much most things.

If there had been hydrogen generators connected to the system they could have used some of the curtailed power capacity to make some and inject it into the natural gas system. Several plants are in the planning stages. Example:

Bigger than LNG? SA to get first "green hydrogen" plant - InDaily

This is true. They could also put the energy into batteries. Like they already do.

Of course. But even though the hydrogen process is quite inefficient, it's energy storage density will make it more attractive for some users.

We all have batteries. One issue with the two 10kw ones I use is the life span of 10 years only. (Flow Batteries ) The lithium battery life span might be a bit longer. Almost Independent test link

A battery is simply a store of energy which can be used when needed. Pumped hydro is a rechargeable battery[biggrin]


If the CSIRO break though is efficient on a large scale then using renewable to make Hydrogen, store as Ammonia then move back to Hydrogen when needed could be a large scale energy store for the much hyped 'base load power' or even my own whole building U.P.S. in a generator which spits our water as residue.

Not yet a buy at bunnings of course An online option for a 5w fuel cell is 19k USD. I wonder how much they cost from Singapore?

This one would make my D3 rock and says it could also by my UPS

Do you reckon Australia is leading the world in Hydrogen fuel research because the govt has sponsored CSIRO to study it in the interests of - despite every other indication of wanting to bury clean energy in the deepest hole it can find - furthering the cause of renewable energy sourced Hydrogen? Or perhaps do you think it might be to increase demand for and thereby profitability of natural and coal seam gas operations?

Hmmm. I reckon I know the answer.

Clean Hydrogen is a pipe-dream, nobody will pay at least 4 x the price for the same gas in the hope it's emissions free. It will be made from hydrocarbon gas. And using electrolysed Hydrogen for stationary power is preposterous. Injecting into the gas grid to burn for thermal energy - sure, why not. Turning back into electricity, no - way too inefficient.
