Re: [Biofuel] Fuel from Algae
Friends I found the thread on algae base fuels interesting. Keith wisely points out that the site given does not show evidence of current production. Knowing absolutely nothing about the techniques suggested to turn algae into fuel I cannot comment further... yet here is a site that says they are producing algae based fuels... http://www.algenolbiofuels.com/thescience-biology.html 4. Algenol's prototype production strains are producing ethanol at a rate of 6,000 gallons/acre/year, and are expected to improve to 10,000 gallons/acre/year by the end of 2008.

Re: [Biofuel] Fuel from Algae
Hi Tim Friends I found the thread on algae base fuels interesting. It only discusses oil from algae and biodiesel from algae. Hm, Simon didn't reply. Funny that, how they never reply. :-) Keith wisely points out that the site given does not show evidence of current production.

Their website is quite informative, good PR job. Hey, that doesn't mean it's all lies, it means it's a good PR job - the best don't need to tell lies. Lots of info there. Their project is in Mexico, that might be more worth a visit. Anyway, this is about ethanol from algae, which is a quite different matter from oil from algae and biodiesel from algae. Ethanol from algae has little in common with the oil route, mainly in that it all exists, it's all done, no need for smoke and mirrors. People have been making ethanol from algae for about a hundred years, there's no production problem and no technology problem, and there's plenty of scope for development. Note that unlike the oil from algae projects, Algenol uses seawater or brackwater, not fresh water - the process produces fresh water as a co-product. Ethanol comes from marine algae, from the sea, not from ponds. Algenol's a bit different, I'll come back to Algenol. It's something of a subset, let's look at the main picture first, which is marine algae. Or rather, as an introduction, let's first have a look at what David Blume says about biodiesel from algae: Algae and biodiesel There has been some discussion about producing biodiesel using algae in constructed ponds. Algae can convert sunlight into fats more efficiently than trees under the right conditions. But the capital and operating costs are much higher than they are for land-based crops. As I detail here, marine algae is a rich resource for alcohol, much more productive and cost-efficient than algae produced for biodiesel. In the long run, mixtures of alcohol that contain 1% biodiesel and cetane-improving chemicals made from biomass will very likely be the diesel fuel of choice, This means the market for biodiesel will be limited to its use as a lubricant in these fuel mixtures. Under these conditions, algae-produced biodiesel may be at a distinct financial disadvantage compared to biodiesel derived from nuts or castor beans; we already produce enough vegetable oil in our currently inefficient ways to make up the 1% lubrication additive we need. That's from Alcohol Can Be a Gas! - Fueling an Ethanol Revolution for the 21st Century, David Blume, 2007, p154. You'd have to read the book to learn how he justifies his conclusions about the future of diesel fuel (he makes a good case). http://www.alcoholcanbeagas.com?bid=2aid=CD99opt= The book has a section on Marine Algae and on Using Marine Algae for Alcohol, very interesting. Marine algae means seaweed, laminar algae like kelp. China, Japan and Vietnam lead the world in marine algae production, of course, and not only for food, it produces a wide range of products. They grow it in coastal farms which can produce large quantities. Marine algae is hardly grown in the US, it's mostly gathered from the wild. Blume wants the US to start farming it. Kelp cultivation provides jobs, food, alcohol, fertilizer, high-value industrial substances, and methane, he says. He foresees an energy return on alcohol production from algae mariculture as high as 15 to 1, with virtually no fossil fuel used in the process, since methane (natural gas) production from kelp is a proven success. Like all farming I guess there are two ways of doing it, using sustainable, environmentally benign methods, or the inevitable disaster of industrial resource extraction that Big Ag calls farming. David Blume's an organic farmer and a permaculturist and he constantly emphasises sustainability, so read on, this isn't Big Oil in green drag. Blume proposes marine algae farming as a potential solution to the dead zone problem, for one thing, and again he makes a persuasive case - use the excess nitrogen run-off that's killing the sea in the dead zones to raise marine algae, he says: the kelp also cools the water, oxygenates it and absorbs dissolved CO2. Blume writes: Do you think I am proposing an
Re: [Biofuel] Fuel from Algae
Hi Erik From another list I'm on: http://jalopnik.com/394479/sears-tower-or-bust-my-algae+powered-car-adventure They actually made a little bit of biodiesel from algae, and they're not a professional lab, but they did say that they had to have a full time lab do some centrifuge work for them. They are very light on details of their process for making the biodiesel, and it sounds like it took them quite a bit of effort and time (though no telling how much of the year was learning *about* the process rather than actually doing it) to make their one gallon of biodiesel, so that probably wouldn't scale well. (Again, they don't provide enough details to know for sure, I'm just guessing.) But it's interesting that high school students could manage to do that just in a science class. They could be members of the oil_from_algae group at Yahoo!Groups, where they've been striving away at it for four years. Maybe they've got as far as actually producing sample amounts these days, I wouldn't know, but they still can't give you a how-to, We're still learning. Best of good fortune to them. Seriously. Meanwhile I still get these angry emails berating me for not providing any information at our website on how to make biodiesel from algae, and send me plans for bioreactors and full instructions. I send them this instead (it's on a macro): http://journeytoforever.org/biodiesel_yield.html#alg If the Yahoo group ever gets a how-to together maybe I'll send them there, and put that on a macro too. Or should I just forward them all to the high-school teacher, since he apparently thinks it's such a great idea to promote it? It's not just them, I also get to spend time trying to help people sort out the mess they got themselves into elsewhere (My first batch turned out great according to the hydrometer but...), or they just bought a processor and now they have 40 gallons of jelly, please help, etc etc. All part of Life's Great Golden Tapestry I suppose, though it's not as if one doesn't have other things to do. The mosquito season's just starting too. :-) /martyr mode Fun to skim through, but kinda worrisome that they just kept running it with the oil light on. I sure wouldn't loan them one of my cars after reading that! :-( Indeed not.

Keith, I tried some experiment with algae: I had algae in a plastic container with some naoh and cow dung (for methane) and applied some pressure through cycle pump and applied some ultrasonic vibrations to the plastic container ( tried all combination by reading net).

What the one out of the five links posted that's by me says is that it hasn't been done YET, in spite of all the claims by people who say they're doing it, only they're not. It's all hype. Biopact says the same, John Benemann says the same, who should know since he literally wrote the book on the subject. Are you going to send him a dumb sneer too? Go have a look, see what you can find on the Web about biodiesel from algae, see if you get the impression that it's certainly the Great White Hope of the future, or one of them, but right now there isn't any outside of a few lab samples. Because that's the truth, but if that's what you managed to distill out of all the hype you'd be very rare. Vanishingly little hope of that, on your current showing.

Re: [Biofuel] Fuel from Algae??
Hello James I'm off to investigate a an algae to oil operation in Phx. I work for a large SW US util that has produced biod from algae. Well that's a little more detail, but not a lot. Previous: Here are a few links. I've driven an E250 van that ran on biodiesel made from algae oil.. Well that would be a first. It needs a little more detail please James, or a lot more detail. Considering that by all accounts there is no such thing as biodiesel from algae apart from a few lab samples and some pilot projects that never get any further, and zero production - but LOTS of hype! Please see the links in my reply to Doug. Now you add this: The big question is how efficient are the oil extraction methods.. So I'm guessing you ran your E250 van on a somewhat bigger than usual lab sample. Progress, hey! :-) But still no real-world production of biodiesel from algae. And there appears to be an increasing number of algae to oil ventures springing up by the month. That's been going on for two or three years, but it's what I said, lab samples, pilot projects that don't go anywhere and LOTS of hype, plus a patent or two and a few scams also. That's why I stopped posting stuff about algae here, and stopped encouraging small-scale attempts, which I'd done previously, and also why Biopact took the same stance over algae projects. http://www.mail-archive.com/biofuel@sustainablelists.org/msg69384.html [Biofuel] An in-depth look at biofuels from algae - 1 http://www.mail-archive.com/biofuel@sustainablelists.org/msg69383.html [Biofuel] An in-depth look at biofuels from algae - 2 Pie in the sky. Here are a few.. http://www.algaeatwork.com/technology http://www.algaelink.com/distributors.htm http://www.originoil.com/originoil/originoil-home.html Same, seen them before. The big question is how efficient are the oil extraction methods.. Algae can also allegedly produce ethanol (75% oil / 25 % ethanol). And using the CO2 from biomass / biogas may have great promise for agricultural applications. I think the big question is, once the efficiency problems are solved (if ever), what sort of technology will it require? All the indications are that it will be high-tech stuff, for industry, perhaps including GMO strains. Not Appropriate Technology, and not for backyarders. In other words, not very useful, IMHO. Best Keith What I find disturbing is that this alternative as well as most of the rest are antique. Examples are : * Jimmy Carter MIT algae oil 1979 * Stirling Engines Ford Phillips 1975 (modern high pressure / high temp incarnation) * Photovoltaics 1950's (HCPV is still under development; close but no cigar) * Geothermal 1920's one of Tesla's favorites * Wind * Solar Thermal AC..(ammonia / lithium bromide) 1974 There has not been a real break thru in alternatives in quite some time...

Kieth, I understand what you are saying, but if the process can be industrialised use waste CO2 from power plants, it would be worthwhile: even tho it might not scale down. regards Doug On Mon, 28 Apr 2008 19:12:36 Keith Addison wrote: Hello James I'm off to investigate a an algae to oil operation in Phx.

Re: [Biofuel] Fuel from Algae??
Just couldn't resist my 2 cents worth here: The biodiesel plant I work for in the Midwest is investigating using algae as a feedstock. I'm not in the loop as far as details, but find it just fascinating and wonder if they're even thinking about going to go all the way and 'produce' it as well. Since they also, at one time, had a soy crush facility on the drawing board to produce their own soy oil. So many plans I've heard it said that the best salespeople are also some of the most gullible when it comes to buying into the hype on new products. It will be interesting to see how/when/if it's all done in the real world. Denise On Mon, Apr 28, 2008 at 4:12 AM, Keith Addison [EMAIL PROTECTED] wrote: b sample.

Thanks James Keith, I remembered the discussion on the list a while ago, had found similar links to the ones James gave me. I was also aware that SVO was an option ( a friend runs a SVO/diesel mix in Ireland in a Rover. I was interested in any info on an Australian development of the technology.

Re: [Biofuel] Fuel from Algae??
Hello Doug et al. There are two major concern signs about biodiesel from algae oil: 1) The algae have to be fed with CO2 during growth. If this CO2 comes from fossile sources, you have achieved almost nothing. 2) The oil from algae is highly unsaturated. This makes it difficult to have the biodiesel meet the EN norm and other standards.

Re: [Biofuel] Fuel from Algae??
jan i may be wrong (and i probably am) but i have been studying this one a bit and i believe the feeding you are talking about is when you use a closed tube type breeder reactor to grow the algae in and there are experiments using exhaust from sources already producing the c02not necc creating ones to feed it, in that aspect i believe that anything that would remove c02 emmisions from something already producing it,, industrial power plants incinerators etc would potentially be a net loss of carbon there are also experimennts in open pond cultivation where the algae does not have to be fed, the drawbacks to this are that the good oil producing strains of algae get contaminated by other species that dont produce near as much oil im hoping this has potential it seems one of the biggest hurdles now is cultivating and proccessing the algae without consuming more energy than is produced seems to be quite a bit of work going on in this field a lot of info can be found at oilgae.com have a good day kelly From: [EMAIL PROTECTED] To: sustainablelorgbiofuel@sustainablelists.org Date: Sun, 27 Apr 2008 14:32:40 +0430 Subject: Re: [Biofuel] Fuel from Algae??

Re: [Biofuel] Fuel from Algae??
This technology was widely covered yesterday in the History Channel, Latin america. There is an electricity central in the US, were the CO2 emmisions are being passed through an algae/light/oxigen bioreactor and consequently the algae grow. The algae is unicellular living thing. Most of it weight is fat, and hidrocarbons and protein waste. Fat is separated and treated to be converted in Biodiesel. Hidrocarbons ar fermented to be converted in alcohol. Proteins will be used for animal feed swine or poultry. The 200 MW electricity plant needs 800 hectares (100x100) to treat all the CO2 waste. US counts with 2900 centrals of this size. I wonder what happens in the night withouth sunlight. Can´t remember the exact place but if someone can dig in the History Channel site can give more precise info on location. Think it is in nevada.
