Still following the post above check the recent grand plan to be carried out between the UK firm Storeega and the Canadian company Carbon Engineering in Scotland:
The plant seems most interesting the problem in my view is fourfold. First of all there´s no way a plant can remove "one billion tons of CO2 from the air every year". The article says that the plant "will remove the same amount of CO2 as around 40 million trees" but the idea that 40 million trees can absorb 1 billion tons of carbon dioxide in a single year is preposterous. A typical tree absorbs around 20 kgs of CO2 per year meaning that 40 million trees will absorb around 800 million kgs or 800.000 tons which is very different than 1 billion tons.
Secondly, using temperatures of about 900 ºC does not seem very sustainable. Also, such big promises will send the wrong message to polluters, and finally, since Humanity is on the verge to produce 2 trillion tons during the next 50 years ("we hit our trillion-tonne limit in under 27 years. And if the trend continues beyond that time, the dark magic of exponential growth brings our planet to two trillion tonnes in 50 years") to remove all that carbon dioxide would require a colossal number of massive sequestration plants. Exactly 10.000.000.000 sequestration plants !
PS - The author of the article finally replaced 1 billion by the more modest number of 1 million both in the title and in the text but he cannot change the word billion in the link of the article
