This doesn't pull CO2 out of the air. CO2 in the air is at 420ppm meaning you would need to process a huge amount of air to get a significant amount of methanol

This doesn't pull CO2 out of the air. CO2 in the air is at 420ppm meaning you would need to process a huge amount of air to get a significant amount of methanol.
This pulls CO2 out of "where carbon dioxide occurs in maximum concentration - for example directly in the exhaust gas stream of large industrial plants". One example would be fossil fuel power plants...
It's an interesting technology but is bound to be co-opted by those who will pretend it is a reason to allow fossil fuel extraction to continue without limit. Eg [1]
Also, many uses for methanol, such as as a fuel additive, release the carbon back into the atmosphere. Once the fossil fuel is extracted and burned, the carbon has moved from the slow cycle to the fast cycle - and it'll stay there.[2]
