The cost difference on consumeable inputs looks like at least $3/kg.
That's with expensive Australian natural gas, and an optimistic take on wholesale electricity, zero costs for network etc. 2/
Winding in a capital component... If Orica plans on using the electrolysers at decent capacity to 20 years (ie they don't just stop when the subsidy runs out) that might add as little 80 cents per kg. 7% discount rate, which is standard for ISP estimates. 3/
But... that calculation right-sized the electrolysers... and concluded just over 30MW were required. Orica (and Bowen) have announced a 50MW project.
Which implies a utilisation of closer to 50% than 80% for their daily output of 12 tonnes. 4/
adjusting up the capital component to a little over a dollar/kg, you end up with a difference of about $4/kg.
This is may be roughly 3X the cost of hydrogen from natural gas?
But that only consumes a $180 million subsidy over 10 years. 5/
So, given that Orica has got $500million grants from the federal government (before we roll in NSW), what does this imply?
Probably that electricity would cost an industrial user more like $230/MWh, or 23 cents/kwh.
That's... realistic? 6/
Remember, we don't have a green grid yet. I think once we're above 80% renewables, costs will hike further. Today small businesses and households already pay well over 30c/kwh.
But at 23c/kwh, hydrogen will be up around $13/kg.
Over 6X current practice. 7/
So, quite apart from there being no chance of this being commercially feasible, ever, due to the cost of electricity alone... the depth of the scandal is exposed in the cost of carbon abated.
Over $1200 per tonne.
This is INSANE. 8/
To put this into perspective, in 2023 the Clean Energy Regulator contracted nearly 8 million tonnes of abatement for around $17/tonne.
Even if $17/tonne isn't realistic, ACCU prices have rarely exceeded $40.
This project is 30X that cost. There's just no way that any money should be spent on such a ridiculously expensive abatement. 10/
That absurd cost of abatement goes to show that Bowen is spending an insane amount of money for a win on Hydrogen specifically. This isn't serious decarbonisation. This is Bowen bailing out his own failed policy narrative, at an excruciating cost to taxpayers. 11/
But my head now turns to @OricaLimited. What are they trying to achieve?
Are they making a profit, or loss on this plan?
A profit would be morally reprehensible. Ripping off the taxpayer. Cashing in on Bowen's recklessness. Being bribed to support his delusions. 12/
But if they're making a loss, the implications are... Well... Maybe worse?
Because that implies Hydrogen is EVEN LESS VIABLE than these calculations imply.
The intellectual depravity to continue is utterly obscene. 13/
I'd welcome feedback btw, from @OricaLimited or anyone else who'd care to critique and cross-examine the assumptions and calcs.
(The largest, most likely adjustment I can find would be to assume the electrolyser capex is amortized over 10 years, instead of 20.)
14/
And remember, this whole project will only displace 7.5% of Orica's natural gas needs.
It's minuscule.
They'd need $6.6bn subsidies to replace it all.
Their market cap is $9.5bn.
This is just absurd spending for a toehold pilot that could never scale! 15/
For context, the other project that's been backed with "Hydrogen Headstart" funding from ARENA is 30X the size. 1500MW.
And it got $815million, not even double the funding.
The Orica deal is just obscene. 16/
And the ISP, from @AEMO_Energy assumes we'll have 15GW of electrolysers, paid for by industry, operating as solar sponges, at around 30-40% utilisation.
At Orica's subsidy rate, that would cost taxpayers... like...maybe... over 200 billion?! 🤯 17/
First, I admire Dave's persistence, and commend his transparency. He acknowledges the limitation of the copperplate assumption, that any energy from any source can be pooled, and consumed in any place is the biggest.
His defence "ISP's got this" will unravel slowly. 2/
But first, "perfect foresight".
Just think this through.
This week was BAAAD for wind and solar. The massive batteries got drained every night for the last four nights. They've never come close to max charge all week.
But this night, when the bottom out, what does the model do? Charge them immediately?
Nope. Leave them drained for most of the night, because the model knows the wind is going to rise. 3/
Yesterday this news broke: transmission costs rising, and pushing up power bills.
For those watching closely, this is no news at all, but belated confirmation from official sources of the inevitable. Quick 🧵on the @AEMO_Energy source. 1/
Two years ago prices were increasing massively. (left chart)
"Unprecedented" we were told.
This year they're increasing even more. But this time (right chart) the costs are almost entirely real, rather than half made up of inflation. 2/
The exec summary states why. The current plan requires an EEAAO build. Everything-Everywhere-All-At-Once.
(I think I'll pronounce EEAAO "Ee-Aw". )
Of course that pushes costs up. Competition for everything... labour, materials, contractors, etc etc. 3/
This insane. @abcnews runs a story about all the endangered wildlife from a UNDERGROUND coal mine extension.
Just 17 hectares of land will be cleared.
Ahem...
JUST 17 HECTARES!!!
The poor bats and koalas!!! 1/
Of course 17 hectares is NOTHING compared to what's required for wind farms.
The 'direct impacts' to the bats is from 630 hectares of land that will WON'T BE CLEARED, but may gradually subside, over years. 2/
I looked up the subsidence reports. The area under the mines may drop a meter. If a 630 hectare area gradually subsides a meter, maybe a meter and a half over the course of many years, I'm pretty sure most of the bats and koalas will be fine. 3/
Spanish blackout 🧵.
Conclusion: relying on wind and solar, ie 'inverter based resources' creates a fragile system, lacking the inertia/system strength that synchronous machines (turbines, from coal, gas or nuclear) provide to ride through faults. 1/
yes, it's comical that just a week or so ago they were boasting about milestones reached being 100% renewable powered. Without very carefully addressing the system security implications of attempting that, it's a precarious position to be in. 2/
Enough of Spain.... what I really want to address is Australia's efforts to ensure we don't end up in the same mess. What careful system security measures are we putting in place to make the precarious position more secure?
The Aus reported maybe not enough. 4/ theaustralian.com.au/nation/austral…
