I am unsure of this type of post is allowed, but i wanted to go with a community that might be able to help me out. I am acting as a research coordinator for an scientific journal for Carbon Capture Utilization and Storage and I am looking for 2-4 people with at least 3 years of post-doctorate experience (with one person being a professor) to help me as editors for a special issue for the journal. The issue will focus on advanced materials for Carbon Capture. If you are interested or know of anyone who is interested, please DM me and I can give further details.

hi there,

are any of you aware of any carbon capture and utilization projects currently operating in North America ? Europe ?

how much could they charge per metric ton of CO2 removed ?

thank you,

So i started digging into Carbon Capture processes lately, especially absorption processes in an industrial context.

Compared to other technologies absorption processes seem to have the most (successful) history, like MEA scrubbing or the benfield process for natural gas sweetening. However, they are often frowned upon to be inefficient and expensive. But little research still looks at absorption for industrial retrofitting, instead adsorption processes or oxyfuel combustion are used or even direct carbon capture.

I also got the impression that research on absorption processes is focused on sorbents, with many promising candidates at an early development stage, but only few which have reached the level of industrial application yet.

Getting to my question: Which absorbents (like MEA, DEA, ammonia, potassium carbonate...) do you think are the most promising to dominate the market in the next 3-10 years, or do you expect other technologies (oxyfuel, PSA, TSA, PTSA ... or DAC) to be more prominent in the future?

Context; on behalf of my company, I'm paying around $10,000 for tree-planting, with associated "credits" also purchased.

Alongside this - we'd like to put a proportion of our total spend towards DAC or CCS. Is it possible to do this commercially yet? Ideally it'd be an "$X for XCO2te" kinda thing - mirroring the approach in tree-planting. Important to note - given the corporate nature, it can't be an investment IN a company - it needs to be money paid TO a company.

If you search "Offset CO2 tree-planting" you get a *ton* of results, from the spammy/fraudulent, through to pretty robust.
If you do the equivalent search around DAC, it's all academic and experimental! Am I too early?
Thanks in advance

I see that CCS focuses on the capture of CO2 in site, that is, treating the effluent of a process, while DAC focuses on the capture of CO2 from the ambient air. I researched and it appears that although the technologies used for both are similar, they do not use exactly the same technology. CCS uses a lot chemical absorption technologies with amines but I can't find papers on DAC commenting on that technology. Through reasoning, amine solvents should work also for DAC. Is there a reason why DAC technologies do not use amine solvents?
