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.

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.

[@oootoob]

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.

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. Thanks for your videos, they are very illuminating and a stark contrast to the general gloominess of these times.

[@clivestainlesssteelwomble7665]

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.

[@ps.2]

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.

[@savroi]

@@ps.2 Thanks for a thorough answer! I still have some doubts when thinking this on a vast scale. It’s one thing to see a few hectares and maybe that’s the scale it should be kept at. Then again a few hundred tons of dried up algae can be handled whilst thousands… Finally I wasn’t thinking about conversion to fuel but rather a compost that could enrich the land.

@@savroi You're thinking about giving this operation an additional revenue stream, aren't you? I can't think of other uses for dried algal biomass. There may be some.

In these locations, seawater is free for the pumping.

@@ps.2 Let’s put it this way, if revenues is the drive needed to take us (humanity) to try new ways to tackle this then let it be. At any rate I think it would be better than just trading CO2 credit.

Technically I'd say it's _indirect_ air capture. The carbon comes from the seawater, not the air.

This looks quite promising, and I think that it's worth keeping an eye on this.

[@kma3647]

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.

[@kurtholmy3448]

Yes, algae can be a feedstock. BUT IT IS EXPENSIVE. But what makes you say "withdrawal of carbon from the atmosphere appears to be necessary"? During the "Cambrian Explosion" atmospheric carbon dioxide levels were about 20 times higher than today. 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.

Yes, i know the algae is quite salty and not immediately useful. But, it has the potential to change the albedo of deserts to the point where rainfall becomes more plentiful. That rainfall can "wash away" the salt into the porous sand below and, over time, leave the top soil in a condition to support terrestrial plant life. It just seems more sustainable to kill two birds with one stone by using sequestered carbon to restore as much of the roughly 25% of the earth's surface (up from an estimated 10% in 1910) that is now desert in carbon-absorbing, oxygen-producing biomass.

[@silvergreylion]

The solution already exists: make the deserts green (and stop deforestation). You can let clay dry to harden it, grind it into nano-sized particles, and re-mix with water to a thin slurry, which you can pour onto desert sand. It'll seep down 30-50 cm, and then you have "sandy soil" you can grow some (initial) plants in. Needs watering at first, of course, which may be the biggest hurdle, but once large areas have grown over, they will attract rainfall by themselves. A few years down the line, and it'll actually be proper soil. Over time, biomass (more or less organically bound carbon) will accumulate, and the soil will retain enough water to completely negate the rise in ocean level. All that's needed is getting funding and people to do the work. The two norwegians behind the Desert Control project are who thought of this process, and are trying to make this happen.

Someone who has worked in the algae industry for >5yrs here. 1. Normal doubling time of algae is not 12-18 days, for sure. Most species double at around per day at low concentrations, but at higher concentrations this slows as other limiting factors come to play. This sounds like a bit of marketing talk to me. 2. This will require large amounts of nitrogen and phosphorus from the sea (or from fertilisers). Typically 106:16:1 ratio of C:N:P. This may work at small scale but at larger scale the local area maybe N or P limited. If 2 billion tonnes are to be sequestered this would mean 20 million tonnes of P would be required or about 5 years of the global phosphorus supply (~200 million tonnes/yr at ~2% P by weight)

Yup, phosphorus is the limiting factor (we do have enough nitrogen). I have been thinking about this for a while, my solution was turn the algae into charcoal and recycle the nutrients.

Or, even better still, sell it at a very low cost, or donate it, for use in saving our increasingly degraded soils.

Unfortunately, removing the salt, and then the energy and logistics of transporting the biomass from remote deserts to fertile farmlands would both be pretty big obstacles to this.

[@robertanderson5092]

It is a carbon credit scheme. Upgrading the carbon is more expensive than cheap desert land

[@patreekotime4578]

If you sell it, you cannot gaurantee it will not be burned or allowed to rot and thus releasing the carbon.

Great video. Made my coffee break. I am enthusiastic but cautious. I'd love to understand the details of how water is kept from the buried algae. If we're just developing a huge source of methane that could be creating a problem rather than solving one. And, as ever, I'd love to see the economics ... indeed, 200 eur/tonne will get you in the competition. 150 or less may get you a win. 100 or less ... we're going to displace even teh stop gaps of traditional CCS.

Are they taking into account potential remain increase at their sites occurring as a result of climate change? Also, are they effectively salting the land and eradicating any potential for it to be used later on, especially given all that biomass they are sequesting. Finally, there was no mention (I think) of existing desert ecosystems in the places they are choosing to bury the algae.

[@CitizenAyellowblue]

My thinking exactly. The reason others are not picking up on this could be that people without ecological understanding believe that deserts are “barren wasteland” which of course they are not. There is a lot of buzz about this without much examination of the impacts. I can’t see that it will be as “green” as the video is suggesting.

[@patreekotime4578]

It is possible that climate mitigation projects are given something of a pass when it comes to environmental impact in Morocco. It is also frankly development money going into otherwise "useless land", or at least that is how it is often viewed by politicians.

[@islandsedition]

@@patreekotime4578 I think the bigger issue with politicians of most stripes is that come election time they like to show something immediately tangible that has bettered their constituents. Jobs, higher wages, better health or social provisions. Putting something in place that fixes the climate is a one time thing that cannot be pointed to as a benefit. Your ability to cover your rent, or buy a house, this month and next month etc is something that is always available to help them say "I did that for you". Whereas " Look you're breathing air that isn't polluted or at 40'C" isn't going to be something they can sell so easily.

👍 Dave!

I'm really glad to hear the info about this. This algae approach is exactly the process I had thought of being the only really practical approach - just takes a lot of lead time to get the strains and process down. Thanks for sharing this!

[@myramisimake-hovell782]

thank you i enjoyed your video, my minds been racing away on how we can live with not only off grid living but also figuring out how off grid we can get with all of todays tech. with algae you can achieve alot of your off grid living needs. the carbon credits you described has further given my idea a feasible way to live off grid and may even give us a way to earn a living doing our bit to our planet thank you for your knowledge and the others willing to share it.

[@benedictmarshall7031]

I would rather the dried algae be used as a food resource, or a biodegradable alternative to plastic. Burying it seems incredibly wasteful unless it could somehow support the re-greening of arid land. Can the algae strains being used do this?

[@cathyhaynes2903]

There's a lot of salt in with the algea. Add in the cost of removing it, and you may not have such an affordable process.

[@TuttleScott]

just seems a shame to go through all that work and then just bury it. even if it was used as a fuel it'd be carbon neutral but then they couldn't get their carbon credit money for it.

[@SeeNickView]

This is literally what sequestration means, guys. It's no different than the conventional CCS ideas/methods of pumping CO2 into fracked rock near offshore oil rigs and other depleted oil deposits. Yes we'd like to rewild many areas of the world as that approach is another serious contender for carbon sequestration, but: We all might have better luck achieving that by changing our diets, going 80-90-95-100% plant-based/vegan, and calling for much of the habitable land in the world dedicated to specifically agriculture (~50% according to OurWorldInData) to be rewilded. Just like anything with sustainability though, having multiple means for achieving the same goal, whether alkalizing the oceans or rewilding the continents, is better than one or two solutions alone. This is what it means to be resilient.

[@DuelingBongos]

I had this exact same idea several years ago. Glad to someone with the ability to make it a reality thought of it too.

[@PalimpsestProd]

I've wondered if all the fish and other things we've depleted were still living how much of a carbon sink would all that life be?

[@SocialDownclimber]

Animal biomass? Not much. All the forests we have cleared? A hell of a lot more.

[@PalimpsestProd]

@@SocialDownclimber Apparently you are unaware that there used to be so many cod on the Newfoundland grand banks that you could lower a barrel and pull them out by the ton.
