The Greens don’t care, but in fact it doesn’t use carbon dioxide (CO2), but carbon monoxide (CO). By combining CO and hydrogen (obtained by decomposing water with electricity) in the presence of tricky catalysts, you can produce methane, ethylene, paraffins, gasoline with an octane rating of 40-55, diesel fuel … In general, a lot of fuel.
But in any case, the CO2 of the greenhouse – which was actually all the fuss about – was not even close to this. Environmental warriors are not ashamed: what is CO2, what is CO – but what is the difference? The most important thing for them is to talk smart about “decarbonization” … After all, to really fight greenhouse gas CO2 in some way, it first has to be fished out of the atmosphere and converted in some way in carbon monoxide CO.
This can be done, for example, by heating it above 2700ºС. Just imagine how much energy will be needed to organize such a process of industrial processing of CO2 to CO, and be shocked. It is possible to decompose carbon dioxide in a plasma using microwave radiation – in a kind of “microwave”. How much clean energy (not to mention the cost of equipment) it requires is also another question.
