Economically viable Carbon sequestration

They have been built despite the uneducated anti pipeline nimbys and the cult of man made global warming.
I don't know of any other nation doing anything like this.
Guess this is fossil fuel free since the whole point is to remove carbon emissions from transportation. 4 wrongs make a right?

While it's probably worth doing, it is a high-tech process subject to all the problems associated which are many. A low tech approach would be biochar.

It may be better to take carbon from biomass instead of atmospheric gas, IDK.

A high-tech approach to biochar would be Cool Planet. Whelp, it looks like Cool Planet was acquired by National Carbon Technologies last June.

The CO2 can be released when the planet cools down for the next iceage, maybe fight off the glaciers for a few more centuries.

Here’s my suggestion.

And it’s a very “green" suggestion...

There called “trees”...

I was gonna say... low cost, I know what is low cost.

In my research, I found that pre-industrial CO2 concentrations were among the lowest the earth has ever experienced (since life existed on it). Photosynthesis stops somewhere around 180 ppm, and we were down to 280. An ideal concentration for plants is somewhere around 800. We're currently at 410.

There should be a positive feedback system to accelerate plant growth since these are "greenhouse" gasses. More greenhouse, more green.

A while back it was thought that green growth in the oceans would increase to remove the CO, haven't heard anything new about adding rust to accelerate new growth, or if there's more green in the ocean plant life

I didn't know 180ppm shuts down photo synthesis. Yeah that would be bad, we need that.

I don't understand why we don't push to make more sewage treatment plants into carbon sequestration areas. I understand that a lot of sewage needs treatment with things like anaerobic digesters, but if a large portion of partially-treated water was then put into large shallow lakes and filled up with things like duckweed or azolla, it would remove basically all contaminants from the water (INCLUDING MERCURY!).

Especially azolla, which can continue to grow in thick mats. As far as I understand it, that's what caused the last ice age, was all the carbon it sequestered. Anyway if we converted a modest amount of sewage plants that had the acreage to put some plants in there...

And maybe a dream, but cattails make excellent sources of ethanol, WAY more than corn. And you can fertilize them with the same (literal) s*** that you fertilize the azolla with.
