> 92% efficiency in converting a tonne of CO2, using just 230kWh of energy. They estimate this equates to a cost of around $100 per tonne of CO2.

Not sure if this is really competitive enough. Just read recently[1][2] that EEMPA based solution can capture at a cost of $47

I’m not sure: is the Gallium a catalyst?

And if so, could it be replaced by orgnano-catalysts which were in the news recently? I only had chemistry in school but maybe it's even as simple as using parts from the chemistry involved in photosynthesis?

But if you get a load of solid carbon as a byproduct that could offset a lot of the energy cost, assuming the solid carbon is in a useful form.

Assuming 16 tons per person per year emissions [0], you can offset 1 person's carbon footprint for $1600 per year.
