How one company plans to suck carbon right out of the air (and make money doing it) (www.cbc.ca)

The roughly two-hectare facility, still under construction, is hosting what could be called a carbon removal Olympics. It will pilot eight different versions of a similar technology using various machines that will suck in air, remove the carbon dioxide and send it to a central plant where it will be compressed and liquified for storage deep underground.

The winner of this initiative wouldn't get a medal on a podium. Instead, Deep Sky, the Montreal-based project developer behind it, plans to take the best versions of the direct air capture technology that prove most effective in Canada's climate and deploy them on a commercial scale all over the country.

DACC is such a scam I'm legitimately upset that engineers fall for it and work on these technologies trying to help. Chemically speaking most carbon sequestration schemes are essentially burning something but in reverse. Now this should automatically set off alarm bells in terms of thermodynamics because enthalpy is a state function and if you have a net release of energy burning something, there is no possible way to do that reaction in reverse without adding that energy back in. So you have to have renewable energy to make it work. But then, I ask, why not just use the renewable energy to replace a carbon source? It's not big enough? Then it's not big enough to offset that carbon source either.

If you had a magical piece of technology that rapidly converted CO2 into long chain molecules using sunlight andv rain water that would be pretty cool. Oh wait? That tech already exists and it's been in existence for millions of years? Yeah that's right it's a fucking tree. Carbon sequestration is a fucking scam to make you feel better about not decarbonizing
