i'm from Algeria and live in the desert, and algae really grow like crazy here even in the middle of summer as long as there is plenty of water i was trying to grow duckweed to feed my chicken but duckweed started dying when temperatures reached 40C so i gaveup and let my small 2x4m artificial pond dry, but ended getting 5kg of free dry algae and i was feeding it to tilapia fishs i'm raising, so i avoided buying expensive fish feed

What saddens me the most is that despite the decades long push to plant trees and stop the deforestation of rain forests, it seems most of that effort has fallen along the wayside. I am in my 60's and can recall hearing about these issues 50+ years ago and we still are decades behind according to experts.

There is just too much money wrapped up in land speculation, in timber, in massive hydro, and in farming for it to ever stop. At the point that nations like Brazil are turning a blind eye to genocide of natives and illegal deforestation in front of the entire world stage, there is just no stopping it. Unless the money spent on mitigation can be redirected so that people in Brazil can have a good living without resorting to these kinds of operations, how will it ever stop? Because the problem isnt a technological one, or even a political one. The problem is a basic economic one. As long as people are struggling to survive, they will do what they can to survive. If that means burning old growth forests, and endangering wildlife that is what it means. If it means murdering native tribespeople to be able to do that, then that is what it means. And lets face it, the richest countries in the world just flat out refuse to take responsibility for their own actions, so how to we expect Brazil or any other equatorial nation to do so? We lead by doing, and our leadership in the "developed" world has been shameful, so there we are.

Fires don't kill most forests, you can see this in BC, you can drive by an area that was burned two to three years before and it's green again, the trees starting to recover. So, yes, fires do affect them, but they are not totally lost. Forests also manage humidity. The true challenge is to prevent anyone from cutting down forests that are 60+ years old (normally called Old Growth). Those are the C02 absorbers, cutting them down is a net C02 bomb as all of the moss and everything else that actually traps a lot of the C02 in these old forests dies, producing methane and C02.

The trouble is that this only works as a business through offsetting, so it only addresses current emissions demand and not historic emissions already in the atmosphere, so unless governments start paying for the capturing of historic emissions, this is never going to scale up fast enough to be effective.

I had a similar thought of growing kudzu in the American south, drying it out and sealing the compressed biomass back into West Virginian coalmines. Humidity and transportation complicate the idea, but if one could show reticent people in those areas that carbon capture could be profitable, minds might start changing.

My guess would be that you are probably correct. Algae is rich in micronutrients, complex chemicals. It can be a part of fertilizer, but then you need a process to produce fertilizer, and buyers. At that point the product is too far from their expertise and they will need new people and it will just complicate things. I am guessing for now they are getting some funding from universities, some fro. governments and carbon capture price is a cherry on top. So maybe they are thinking about your idea as a possible market in the long term. The sad truth is for now is the demand for algae products is minimal.

Technically I'd say it's _indirect_ air capture. The carbon comes from the seawater, not the air. It is ultimately absorbed from the atmosphere, not by the facility, but in the several square km of sea surface _near_ the facility. The oceans already absorb most of our excess CO₂ emissions. This works by giving them additional capacity to keep doing so.

THis is a concept that I was wondering about since the past 4-5 years. But thought there are lot of smarter people who know what they are doing. Really glad that this is a very promising tech If all the plants can put 21% of entire atmosphere with )2, then definitely they know how to scale naturally. So definitely theycan take out the CO2 as well . I once read an article that these dried up algae can be put back into unused mines for sequestration for good. Re using the desert area for this is the best part. The evopration from the ponds can also help the local climate by keeping it cool for vegetation to start. Big boost to the economy of the people living in such airid region. I love this project. I really hope/pray that they succeed.

look up Raffael Jovine, the double Ph.D. marine biologist who founded Brilliant Planet. He says his desert near-ocean algae farms could store, at best, 10 gigatons per year of co2. But this same concept can just be scaled bigger, more inland! Algae is what created oil in the 1st place. I was pushing this idea 20 years ago. Exxon buried it but ecology is bigger than big oil.

There are a few things I don't fully understand. 1- While being dried up, doesn't the algae release at least some CO2 back to the atmosphere? 2 - Once the dried up algae is buried does this mean the land on top becomes "sterile" forever or can it be reused after a period of time and if so, how long? 3 - I imagine a few of this recycling plants won't affect climate, how extensive can this be without affecting at least the local climate? 4 - Are there any studies or projects to use the dried up algae to make something out of it? I think if that can be found a way to use this algae without releasing it CO2 back to the atmosphere this method would be not only sustainable but a great development asset.

By adding the algae to the soil or sand you begin to rebuild a living soil so not only do you bind the mineral soil together and hold on to most of the CO2 that was in the algae but you also activate a living soil which in itself sequestrate's Carbon in large amounts globally if maintained properly.. currently mechanised farming degrades most soils. The biota on and in revived soils increases the capture and redirects the flow of carbon through longer paths in the systems. As for food and products made from algae there are hundreds from cosmetics, animal feedstocks... which may also help reduce methane produced by cattle. Its been a food source since ancient times and used as a fertilizer to add to thin soils throughout the western British isles and Ireland's potato crop was grown in fields fed on storm washed seaweed from the beaches. The latest super food is Spirulina a blue green algae thats grown and dried to add to foods and drinks as its the rich in Omega3 vitamins .. Fish even Salmon Tuna Mackerel etc that we eat for their oily flesh that helps with the body's management of cholesterol.. and the growth of the brain and protection of nervous system. Dont actually make those valuable chemicals ...they just concentrate them from their food chains.. that start with BG algae in our oceans. Farmed fish have to be fed concentrates from crops like flax and other oil rich seeds to produce the Omega fatty acids..but its noticeably less than in wild fish ... so you have to eat double. 🐟🐟 The farmed fish 🎏 to get the same amount. They can also remove nitrates and phosphates from utrophicated water.. a common problem with farmland run off where fertilizers have been added trying to boost yields. Carbohydrates ...plants/algae can be converted to plastics alcohols ..etc..even into oils hydrocarbons. Our present day Oil and gas formed from the very burial and change under pressure and some temperature and away from O2 of ancient sediments laden with organics from ancient phyto and zooplankton. The Blacksea is one such possible example of this ongoing process. Oil and gas are too valuable to burn ....is a critical and very early observation of one of the pioneers of oil chemistry.

1 - Probably a little, but not much. As Dave explains, the idea is to dry it out fast enough and thoroughly enough to prevent it from rotting. This is why a desert is an ideal location for this tech. 2 - This desert land is already pretty infertile. Anyway he said they're burying it 4 or 5 meters deep. That's far deeper than most plant roots, even if you were to try to turn this to agricultural land. 3 - I don't see how local climate is particularly affected. Additional evaporation from the open-air tanks? Given this is next to the ocean, that seems meaningless. Depletion of dissolved CO₂ from the local ocean? (Technically when it dissolves it becomes carbonic acid, H₂CO₃, which is why atmospheric CO₂ causes "ocean acidification." And why even without sugar, carbonated water harms your teeth.) Sure, but that naturally balances out both with ocean water mixing, and with absorption of CO₂ from the atmosphere. And atmospheric CO₂ mixes very quickly around the world. 4 - In theory any biomass can at least be burned for fuel and thus energy. But of course then you're putting the CO₂ back into the atmosphere. And given this project is designed for desert environments, there's not necessarily a good market for excess energy there anyway. And if you wanted to produce power on site, you'd do better adding solar and/or wind, as mentioned in the video.

One small issue. Much of the world's coastal deserts have very little ocean upwelling, which would mean that to get sufficient nutrient to grow the algae from the ocean alone would require pumping water from much greater depth.

This is very interesting as a carbon capture and sequestration technology, and as you pointed out, to reach stability and sustainability or the global environment, withdrawal of carbon from the atmosphere appears to be necessary.

The only way this is "sustainable" is if you're able to take the solar energy back out of the carbon-based chemical bonds later. The cycle is that you're releasing energy from carbon-based bonds when you burn fossil fuels. Then you use algae to photosynthesize new carbon-based bonds which can again be used. Of course, it's highly inefficient because photosynthesis is inefficient, but that's the process we have for converting solar radiation into usable power. And of course, the idiots doing all of this have no intention of actually using the power they're storing up for some sort of useful purpose. Nope, they're burying it in the ground because idiot rich people are paying them billions to do that.

Most contemporary plants, including important C3 food crops, evolved under conditions of considerably higher carbon dioxide than we have at present. Global Greening is an increase in Earth leaf coverage observed by satellites over these past decades; this indicates that a return to pre-historically higher atmospheric CO2 levels is largely benefitting the biosphere. There is no carbon crisis.

Now you have a input stream to ensure that the process will not only continue but that more players will get in on the game. Collect the oyster feces and psudo-feces and bury this material. Oysters produce more feces than cows, kg per kg. If you want to add another stage, grow macro-algae such as the type that makes caragenan, agar or that are used for sushi. More income. You don't even need the carbon credits but why not. If someone is willing to give you more money, say thank you.
