Our current cost per tonne is in the same order of magnitude when including the carbon value from the European ETS. The key success criteria for making large plants profitable will be connecting to cheap electricity at <$50/MWh we're in the black
It’s an interesting point. The most sunny region might be not the target market. Then you need to factor in the CO2 emissions arising from the transport to consumers.
also, transport is a minor fraction compared to the net saving
Of course they are now electrolytically strip mining the entire ocean floor…
Can you handle intermittency in your power, or do you need to run continuously? What capacity factor do you assume in your cost model?
Whether your country has invested in renewable sources like hydro plants and associated high-voltage, long-distance transmission lines is what matters. The geography of whether hydro plant is near the coast or not is of less importance than whether it exists or not!

We are a bit behind in the US in credits or taxes, we are now treating the social cost at $51, but not using that for tax or trade policy.[1]
There's one more number that is useful to get a numerical sense of the costs: $258 / ton, an estimate of the actual cost to society. [2]
