Carbon Capture

Nexus Aurora – Carbon Capture

Nexus Aurora Carbon Capture (CC) aims to provide a lower cost Carbon Capture solution for many purposes, home carbon capture to increase air quality, and even scrubbing Co2 in space stations! Our current plan is to use Soda Lime or Sodium Carbonate to achieve this affordability, while still offering an excellent CO2 scrubber.

I'm ngl between SSAM + school + MAC cubsat stuff I don't have much time for any other projects, but near the end of june when school ends I should have more free time to work on this project too

@​bluecatoutside @​VinFaz (Vincent) @​Orion Lawlor - Alaska Does any time work better for you?

I wonder how much better your scrubber is, since it exposes more surface area
A Jazz God May 2, 2022 @ 3:58am
Right now I'm working with EHRI to look into a biological method. Space would still be a concern, but the ocean has plenty of that to spare.
A Jazz God May 2, 2022 @ 3:57am
That too.
Orion Lawlor - Alaska May 2, 2022 @ 3:57am
At scale, the dominating cost is probably the cost of the trays, racking, and moving trays to the solar furnace for bake-out. The slow scrubbing rate makes this require a lot of space.
A Jazz God May 2, 2022 @ 3:57am
That's a pretty hefty price point given how much carbon we're dealing with.
Orion Lawlor - Alaska May 2, 2022 @ 3:55am
The scrubber reaction is Sodium carbonate plus H2O and CO2 makes stable Sodium bicarbonate. You can drive off the H2O and CO2 again to regenerate sodium carbonate by gently heating the sodium bicarbonate to just over 110C, such as via solar heating. Other than mechanical degradation (clumping) there shouldn't be a limit on how many times you can reuse it. Sodium bicarbonate is a few hundred dollars per tonne, and once baked to sodium carbonate seems to scrub over 30% of its mass over a month or two, which is at least 20% of its mass in CO2. So you're looking at about a thousand dollars for the raw material to scrub one tonne of CO2 per month, by just sitting in a thin layer in a tray and having ambient air naturally drift past it. Ideally you'd do something useful with the H2O/CO2 released during regneration, such as electrolyzing it back to a fuel, but if you just want lower indoor CO2 you could just bake it out.

A Co2 scrubber is a good first step on the way to large scale carbon capture though
sudo killall windows May 2, 2022 @ 1:16am
We don't have solid data on CO2 capture yet, since Orion and Vincent were going solely off of weight and not CO2 readings. But from the weight readings it seems to be working
bluecatoutside May 2, 2022 @ 1:01am
I'll likely become active at a later date. But I was drawn to the environmental bottom line of carbon capture and storage. A CO2 scrubber is a social bottom line concern, improving human offices and habitats.
A Jazz God May 2, 2022 @ 12:44am
what's the cost to capture ratio for that?
sudo killall windows May 2, 2022 @ 12:41am

Tech_And_Sci April 20, 2022 @ 6:49pm
The problem here is that genetically modifying something can also have unintended consequences. And accurate genetic modification itself is a difficult thing to do with the technology we have today

*A quorum killswitch is an engineered deterrent against excessive growth in engineered organisms. It effectively kills whatever has them whenever they get too far from each other*
A Jazz God April 20, 2022 @ 5:58pm
They note in the paper that in order to reach the 10 gigaton carbon sequestration benchmark, you'd need a body of water around 20% the size of the amazon rainforest, or about 1.4 mil square kilometers There just so happens to be a large source of carbon based polymers floating in the pacific ocean that's around 1.9 mil square kilometers, and we know of genes responsible for letting bacteria survive off those kind of polymers as a sole source of carbon So the idea came to mind, would it be possible to genetically modify azolla to be resilient enough to survive in the pacific saltwaters, and at the same have it feed off the pacific garbage patch It'd solve 2 problems at once On top of that, you could potentially engineer the azolla to need to eat plastic (and maybe include a quorum killswitch), preventing it from spreading too far past the patch and becoming an invasive species
A Jazz God April 18, 2022 @ 3:15pm
Regarding phosporus, last year my university's IGEM team (semi-competitive genetic engineering club) designed a biological system for repurposing waste phosphorus, which is a common water pollutant. Not sure about potassium.
Orion Lawlor - Alaska April 18, 2022 @ 8:30am
Here's the latest data from my sodium carbonate vs calcium hydroxide scrubber comparison experiment. The sodium carbonate has been regenerated once, but seems to be following basically the same scrubber curve the second time around. Calcium hydroxide is still working but *very* slowly, possibly related to my low humidity--everything seems to scrub faster with higher humidity, but calcium hydroxide can actually lose mass in dry air.
Orion Lawlor - Alaska April 18, 2022 @ 8:25am
This seems to be a decent paper on the Azolla (duckweed) fern as a CO2 sink: https://link.springer.com/article/10.1007/s11356-021-16986-6 I wonder about fertilizer demand: Azolla dry mass is 0.25 to 1.4% phosphorous and 1-3% potassium, so if you're looking at sequestering gigatonnes/year you need huge sources of P and K.
A Jazz God April 15, 2022 @ 3:55pm
Searched through the old messages, I am surprised no one here mentioned azolla

We were making some really good progress, with @​VinFaz (Vincent) and @​Orion Lawlor - Alaska having functioning prototypes. I think the only thing we really need to do to revive the project is to figure out a better meeting time that we can all make consistently

Ross (/u/_albertross) March 17, 2022 @ 11:16pm
Even without that, the key metric is cost not efficiency
Orion Lawlor - Alaska March 17, 2022 @ 10:43pm
In the US southwest, extensive solar has actually put the energy market into "the grid will pay you to *take* electricity" (post-scarcity) mode during the daytime. Since thermodynamics means CO2 to fuel is guaranteed to require energy, sourcing that energy from plentiful solar (or fusion, etc) means it may be better to use inefficient processes that scale quickly and have minimal capital overhead.
Tech_And_Sci March 17, 2022 @ 4:58am
Even the most advanced carbon capture is notoriously inefficient
Tech_And_Sci March 17, 2022 @ 4:57am
The main issue is what is the efficiency of the conversion from CO2 in the air to gasoline and jet fuel

Would it be possible to get some 3d modeling done before the meeting to allow for other people to pretty easily run the experiment?
Orion Lawlor - Alaska March 8, 2022 @ 6:26am
I realized I could *make* calcium hydroxide scrubber, by adding sodium hydroxide solution (drain cleaner) to a calcium chloride solution (spent dessicant), although this comes out as a brilliant white wet mud and needs to be washed, filtered, and dried. This calcium hydroxide scrubber was just dried on a hotplate for a few hours, so it might have already scrubbed a bunch, hence the rapid deactivation. Or calcium hydroxide just inherently armors itself over with calcium carbonate (limestone) and slows down? Both scrubbers seem faster in higher humidity, which may be most of the sodium carbonate curve.
