This company seems to be making good progress. I don’t know how old the page is though sorry.
Also of interest is the proportion of Australian exports on the economy. I suspect the ratios have shifted a touch in the last year or three as well.

current economic thinking for Australia

unemployment is good because it keeps wages down, when wages are down inflation is down which makes it good for exporters – all we need to do is become like china and things will be very good – except we don’t manufacture anything to speak of so apart from crushed rock and some agriculture and animal cruelty we don’t have much else to sell, except land to foreign investors.

town planner, doctor, economist, handyman, is there anything wookie doesn’t know about…

I trust his advice on washing machines.

Looks to me as though coal seam gas has more potential than anything else for expanding the Australian economy.

For me, the important part is this figure:

Compressed H 200 bar -
LaNi5H6 –
MgH2 -
NaBH4 -
Li BH4 -

MgH2 looks best, but requires 350 degrees and above 300 bar to operate. Going down to 150 degrees would make it worse than straight compressed hydrogen at a lower pressure of 200 bar. 350 degrees is achievable, see for instance
But 300 bar is not easy – the maximum pressure inside a car engine ranges from 75 bar for a production car to 100 bar for a race car.

> Today only a few materials (e.g LaNi5, see the chart below) can absorb and release hydrogen at ambient temperature. Unfortunately, these materials are heavy and thus can only store small amount of hydrogen (less than 1.5 wt%, i.e. 1.5 % of their own weight).
Many other materials, like borohydrides, can to store large amounts of hydrogen (up to 18.4 wt%). However, the use of this material is currently limited by the need for high temperatures to enable the release hydrogen and extremely high pressures (above 300 times atmospheric pressure) for hydrogen uptake.

That’s what I thought. Hydrogen power can’t work because there’s no good storage mechanism. The chart doesn’t mention pressure.

From the web. “Around 15% of the usable energy from the hydrogen is lost on compression”.

Engineer wanted.
It’s said on the above chart that 4% of the weight of a compressed hydrogen cylinder is hydrogen. Using pressure vessel design, that’s true for what size tank? Given that a sphere han hold a higher pressure than a cylinder (because the casing is in pure tension), how much extra weight of hydrogen could you get out of a spherical tank?

PS. I assume from what is in the article that the idea is to load hydrogen into the matrix at the service station and then swap the solid component in the car with that in the service station. Anything else and the car would have to contain a pressure vessel capable of at least 300 bar for hydrogen in solid solution, which would make the energy density far worse than straight compressed hydrogen at 200 bar.

We seem to store a shed load of hydrogen as water, this seems to have worked OK so far.
