In 2010-11 I worked on the process engineering design of an algae biofuel project. Producing fuel at that time was a non-starter as the ability to get enough sunlight into a mass that would produce any significant amount of algal oil was near impossible. The people who had worked on an algal strain for a decade tried open circulating channels, plastic tubes and a number of other ways to get light into dense slurries of their specially selected algae. We finally convinced them to look at using the algae to produce edible oil and a high protein flour substitute from the spent algae. Both had excellent properties for high value food use. The problem is that even after genetic modification they just aren't productive enough.

The algae can then be dried using the heat from the 1.5 MW of biomass boiler or heat from the 1MW GSHP already installed on site. The info re Asparagopsis taxiformis is excellent information which we will now explore further. When we get the process right then modular system could be deployed onto farms with livestock and biomass boilers so farmers could cultivate their own algae feed additive for their livestock.

So glad to see a great KZreadr covering this incredibly powerful climate solution! More attention on this!

Thanks for another great video! The potential of algae seems limitless, because it grows on its own. Unlike machinery, your algae facility will upgrade itself if given enough sunlight, water and nutrients. That's why the idea of growing algae for carbon sequestration actually sounds plausible. If there's any method of removing carbon from the atmosphere that might actually make a dent in the enormous amount we emit, surely it's this one. You said that it would require "extremely careful stewardship" to ensure it didn't get out of control, but surely this could be done by careful placement of the algae farms (putting them in the "desert" of open ocean, nowhere near coastlines or reefs) and using species that don't normally cause blooms in the wild. We can figure this out. As for the other uses of algae... There are so many of them. It's wonderful. I remember debating people on the Internet about using algae for biofuel back in 2001. It's been over twenty-one years and it seems the researchers are finally just about there, thanks to Exxon.(!) I don't know if algae biofuels will be energy intense enough to use in aviation, but algae is pretty much the only feedstock that might make sense as a biofuel. It has more potential than dead ends like ethanol, anyway. The other uses of algae you talked about are all wonderful in different ways. Bioplastic is pretty new, but it might be big in the future. Then there's more immediate applications, like growing algae on an industrial scale for use as a protein feedstock. I bet there's a huge potential market for that. And the industry it creates will develop technology and experience that'll help in growing algae for other uses. And who knew that Asparagopsis Taxiformis could nearly eliminate cow farts? Apparently some scientists did. What a great discovery. If they can farm it on a big enough scale, this stuff should be added to cattle feed all around the world. It'll help the cows feel better _and_ reduce methane emissions. Win win!

Here in the sea between Sweden and Finland we have a problem with algae blooming/ booming every year due to much fertilizer making its way into the sea via groundwater and river streams. These algae show up as a natural response to human action on the land creating unbalanced contents in the water. As nature will always do. I assume algae farms near the coast could "fix" this problem, benefit from the fertilizer problem and making it a solution. I don't see it happening any time soon tho. Some oil fields that have been closed for decades are able to produce again, scientists claimed for many decades already that crude oil is being produced by the planet on a quicker scale as we are told. If humanity learns to use this energy respectively we wouldn't even run out of it. The reason they want crude oil to be called a rare mineral is merely a genius move from a business perspective. Having said that, if the day comes we can make algae fuels/ plastics efficiently i will be very happy.

Great video! Sounds like a promising piece of the solution. I like the carbon capture and potential use for aviation. Here's to the hope it can live up to even some of what you mentioned in your video!

As an old cowboy whose first 4-H project was a.black Angus steer grown as a beef producer, I can say irrefutably that if dairy farmers can feed their stock with the 2% supplement with, perhaps, some tax incentives (maybe not) they would do it. If the supplement could replace some element of the existing feed used and not impact milk production and not appreciably increasing the price of the feed it could be rapidly accepted in the dairy industry. I can see how to do that reasonably quickly. Two element of quick acceptance to be clear: not increasing the price per ton and not impacting milk production. As to ranches cattle are grown for beef. The price factor remains the same and second factor becomes weight production. Price per pound on the hoof is critical to a ranch or feedlot success. As a beef segment a feedlot vertical would have rapid acceptance segment after several independent simultaneous demonstrations in different areas and climates. Range beef is an different business than feedlots. Methane reduction from feedlot and dairy operations should be substantial based on the data in this video. Can you or others comment? I grew up around lots of dairies and worked several ranches as a younger man. Hell older man in 2005/6 as a respite from my profession. Hard but fun being horseback fulltime again.

Growing algae and, not processing it but simply pumping it down into depleted oil wells could be a good way to draw down CO2 out of the atmosphere. We have to get back to 325-350ppm somehow and using algae for this may be the quickest and cheapest way to do it...

One very important Algal Oil study was NASA’s Omega project driven by Dr Jonathan Trent, now founding director of UpCycle Systems. What the Omega project demonstrated was that the primary limitation to algal production is fuel, specifically CO2. For starters the fuel is in the atmosphere in very small quantities, and secondly when you do have it in sufficient quantity to promote explosive algal growth, the next problem is feeding that CO2 to the algae with out killing them through water acidity. Thinking about it there may be a solution by creating high CO2 content microgranules that the algae can attach to to absorb the CO2 directly rather than from the water.The Omega project explored growing the algae in plastic bags that float on the surface water in a water farm environment. The project looked at the ideal location was adjacent to coastal sewerage farms drawing on released CO2 and nutrients. Send Jonathan a text, I’m sure he would happily contribute.

So much Information ....Thank you

Re searching for algae with high oil content: If there is a "zooplankton" with high oil content, it can be fed using the "phytoplankton" with low oil content. This two-step process is less efficient than having oil-rich algae (zooplankton turns some part of its food back to CO2), but maybe still better than the currently used biofuel producing methods?

Hey, finally something I can talk about with authority! That DOE project, my startup is going to use technology that came out of that program. The problem with biofuels is the same as many of these green alternatives-they simply can't compete in costs. We could ramp up algae production to make biofuel, and replace many fuels we use. But why would we when it's like 5-10x more expensive? News flash, we're not going to. It won't come into widespread use until there's some kind of regulatory change such as massive carbon tax. Or the technology improves so radically that it is 5-10x _cheaper_ than regular oil.

A decent carbon tax that made a carbon sequestering fuel more cost effective than oil fuels would be amazing.

If we could get politicians to quit releasing hot air that would be a god send.

I suspect soon we will see some open source algae at home carbon capture systems. It seems relatively simple and can use hardware store grade components.

Growing algae is indeed easy. The harvesting part is difficult though. I don't see that happening at home in an environmental friendly way.

Glad and surprising that you and many people in this channel which usually pro battery,solar&wind appreciate potential of some non-direct electrification tech as well. There are always technology that worked really well in some areas but in another areas make existing problems even worse.

I see 1 acre in my imagination being used like this... 1.Elevated run-of-thtube PV panels covering the entire acre. 2. Agrovoltaic regenerative farming of plants and animals underneath. 3. Bio-Algae tubes used to cool PV panels. 4. Thermal Electric Generator (TEG) tech converts the thermal variances into electricity. 5. Vortex micro-hydro power plant at the bottom end of the Algae production, closed-loop system as it meanders thru the solar farm. 6. More vortex power plants.. Place the PV panels on contours, divert a portion of creek flow into controlled ditches back and forth across the field until it dumps back into the same creek. Turbulent vortex generators placed at each drop of only 6 feet. The amount of water retention in the soils equates to aquifers re-filling, springs start coming back which then feeds the sustainable supply of water that grows the Algae. 7. Fresh, purified water is a byproduct of the system that can be harvested or fed directly to animals below the PV panels or cycled thru Algae tubes.. I could rant for hours about what a modern-back-to-the-future farm would look like.

Maybe a conveyer machine could bring it slowly onto land where it would simply dry. Maybe such a machine could be adapted to lift the algae onto a floating island of itself! The carbon density is impressive!

Algae will be the future feedstock for livestock, increase the health of livestock and people

About 30 years ago, in the 90s, I invested in both the algae oil and the bio plastics making a lot of money with both. So this,to me seems like old news.

Well, you got lucky, Bill. Algal fuels and bioplastics are still not a significant technology.

This video remindedme of some technology i heard about in the iet magazine 10-15 years ago called thermaldepolymerisation (TDP). From memory the case study was a chicken farm in pennsylvania. The point being TDP is old tech, it was used by Apartheid South Afria to produce synthetic oil in the 70s/80s, its just generally expensive and inefficient. The PA case study found if you assume the waste organic matter being fed into the process from a chicken farm, was just that, waste, then it was something like 80% efficient. Combining TDP offshore, with an algae or kelp farm producing organic matter, and last weeks video producing power, presumably you could manufacture green oil/gas.

I hope we do not repeat the same mistakes with monocultures while ignoring the surroundings that we did on land.

A research group in the Tri-Cities here in Washington state, found they could fossilize algae in about 15min. Oversimplifying here, but basically they run a slurry of algae and water through a fancy pressure cooker and end up with crude oil. The upside is the process is not picky about which species, or combination of species are used. The downside is it's incredibly energy intensive. Was trying to find more information on this and if any head way had been made to make this more economically viable. Was hoping you covered it here

You hit the nose on this one. There is interesting directive evolution work being done to improve chlorophyll and lipid production with different algal strains. There may be a wonderful symbiotic relationship of carbon capture and fuel production, harvesting algal oil and meal from growth optimized by capturing CO2 concentrated flue gas… some day. Capturing CO2 from a power system’s exhaust and producing algae on a continuous basis could provide about half the fuel needed to run that power plant. Algae based biofuels would be great for aviation considering the carbon accounting.

I'm pretty sure that open algae runways are not suitable when rigorously targeting a specific algae strain due to inevitable contamination. Especially with a gmo as the chance of it escaping to the greater environment would be very high. Which means you need an expensive enclosed system.

I keep saltwater aquariums and aquaculture live corals, Have had a number of rudimentary experiments using the excess nutrients in the reef tank wastewater to grow algae for these purposes. Have attempted plastic with some species of micro and macro algaes. Hoping to find what the net carbon footprint would be with a certain amount of coral growth and algae growth of different species- as corals utilize the carbon cycle to calcify skeletons.

PHB sounds good. I'd guess it needs to be massively scaleable if plastics companies can use it ...

The potential for kelp farms along the coast is enormous; from what I’ve read, massive projected growth in seaweed farming here in the US is due to its profitability and versatility across industries. So far it’s grown for: Nutritional supplements, vegan protein, carrageenan content (for innumerable uses), green nitrogen rich agricultural fertilizer, and biofuels on an experimental basis. The potential for large scale industrial uses is growing with the economies of scale, and when a few of these billion dollar processing facilities are in operation, we may see a serious shift towards seaweed as a multifaceted, and profitable, solution for many separate environmental challenges.

Enlightening, thank you

What's really good about some algae types is that they grow in salt water unlike most plants that need fresh water which is in short supply in many places.

Excellent video!

Doesn't burning biofuels also release CO2 into the atmosphere when you burn it, or am I missing something?

@JustHaveaThink

It does David, so it is certainly not the perfect solution. but because algae grows so quickly and captures carbon dioxide so effectively, it is carbon neutral, as opposed to using fossil fuels that have been in the ground for millions of years, and burning their carbon content which can never be recaptured. And because algae can be grown at sea or on otherwise non-productive patches of earth, it will not impact on current agriculture spaces

The relevant question (in terms of our predicament) is not can biofuels replace fossil fuels; it is how best to drawdown carbon and use the most carbon neutral fuel. Instead, the U.S. spends $5 Billion or more per year on Industrial Carbon Removal (or ICR) that emits 3.7 times as much carbon as it draws down; while not funding forest fuel reductions using hand tools to convert fuel reduction materials to recalcitrant char via pyrolysis and sequester it safely in the soil, on site, for hundreds if not thousands of years---which would reduce the amount of CO2 emitted by 50%, while also increasing the longterm fertility of the soil by capturing nutrients, forest resilience to fire, and reducing wildfire intensity. Clearly, solar panels on rooftops generating electricity appear to have lower emissions than ICR biofuels, but we won't know if we don't "have a think about it"......and take action. (for ICR subsidies see J. Sekera "Assessing Carbon Capture: Public Policy, Science and Societal Need, 2020)

@@JustHaveaThink good answer… it is important to do a thorough accounting to truly demonstrate carbon neutrality including any logistic or transport emissions that are involved to get to the end use of the product.

Looking for the link to the podcast mentioned …. Help please. Thanks 😁

I have tried growing spirulina and I found that it grows faster and has a higher lipid content when exposed to taxifolin (a agricultural growth stimulating antioxidant). I am not a profesional algae grower but I wold like to know if research is beeing done on this chemical in algae cultivation.

i did grow algae at home for a project to make biodiesel, but the problem was the extraction, not enough QTE to test chemical ones i tried to use a mechanical way but the pressure wasn't enough to overcome the cell's walls, i think i need to reach supercritical water phase for that to happen, not enough money to test that out so for now, i feed my chickens with duckweed and i will start farming fish using algae in a pond or a tank

7:23 to me, looking at all these algae in a lab and ponds is completely the wrong approach. We need to cultivate and expand the use of KELP in the ocean, to help rebuild those ecosystems while making useful products. It's maddening considering the fact that these oil majors have Already invested so much infrastructure and R& D into building offshore platforms which are perfect for cultivating kelp in the ocean
