While very interesting, and hopeful for the future, it is not yet cost effective to do on a large scale. It is a nice 'proof of concept', but alas, the current price of oil is a cheaper alternative. Until such time as either the price of oil goes up again, or the cost of production goes down drastically, you won't see many more of those plants built.
No one will have to build any of those plants, they already exists in the form of modern oil refineries.
Audi bought an old refinery to make their plant.
At the current claimed efficiency (70%), it looks like the breakover price point is about $90 a barrel oil.
Somewhere around that price it will be more profitable for the refinery to make the fuel products they sell
from atmospheric CO2, electricity, and water, than to buy, transport and refine oil.
Do you remember when a Saudi Prince said Oil will NEVER be over $100 a barrel again, and people laughed at him.

He may have been correct, If oil has a ceiling price, above which refineries stop buying, the price will cap out.
For over a century refineries have been doing olefin cracking, to get the most fuel product out of each barrel of oil.
From what I understand, the Sunfire process makes the olefins suitable for the reassembly process to make whatever fuel is needed.
People demonize the oil companies, yet oil companies have been at the fore front of many of the technology advances of the past century.
Chemicals , plastics, new materials, ect, the Scientists and Engineers at places like Exxon, Shell , and Dow, lead the research.
They hire the best and brightest minds in the industry, and they do not usually publish their work.
I would be surprised if they did not already have this process refined and ready to go.
