I fully agree with your perception of CCS but i think it's only a small historical detour of about the same scale/level of harm as cellulosic ethanol or concentrated solar thermal used to be. Tried, failed, moved on. No one bets the farm on it, Fit for 55 plan for example, makes no mention of CCS.

Not here in Australia.

Have a look at: https://www.kwm.com/au/en/insights/latest-thinking/ccs-in-au...

(Burrup is the one I mentioned)

Thats $250 million of committed funding to a range of high scale projects by the gas industry, coal-seam gas included.

That's right, but by comparison, Australia has 25GW of solar installed, so this funding represents only $0.01 per watt of installed solar, probably less than 1% of subsidy that went to solar. It's an OK amount to try and fail once.

Most of that is 25GW is recent and cheap PV at close to $0.02 per watt. It’s the tiny fraction from before 2015 that was really expensive.

A 250m subsidy to grid solar right now would easily increase total installed solar to 100GW+. So, I wouldn’t be surprised if that project alone was a larger subsidy than every subsidy given to grid solar in Australia.

$0.02 per watt??? don't you confuse with the cost of kilowatt-hour of power? Cheapest installed solar is >$1 per watt, most of the time about $1.5-$2 per watt. Cheapest Chinese panels themselves are about $0.25 per watt and they make a tiny part of the overall setup costs.

Loans.

Nobody is going to hand out a subsidy and say here buy panels with this. It’s all about the multiplier, even home subsidies don’t 1:1 pay for panels it’s at best deduct the cost from your taxes saving 30% or whatever on the cost and often less than that.

So, that’s where the ~2c/kWh shows up it’s roughly the minimum cash on hand someone needs to get the ball rolling for loans on a grid solar project assuming a proven track record. Now hand someone with that track record 250 million free and clear and not only can they get loans but they can also attract private investors.

Of course the risk is you hand out money to projects that would happen either way and get noting for the subsidy.
