Liquid Hydrocarbons on Demand?
January 18, 2011 8:15 AM Subscribe
In September, a privately held and highly secretive U.S. biotech company received a patent for a genetically adapted E. coli bacterium that feeds solely on carbon dioxide and excretes liquid hydrocarbons. Joule Unlimited, co-founded by George Church, appears ready to forever alter the way we produce fuel.
Additional information.
Additional information.
Converting CO2 to hydrocarbons is a endothermic reaction, so the bacteria cannot be feeding "solely" on it.

I don't want to be cynical. I want to believe. I really hope that somebody will do something that makes us stop pulling oil out of the ground as desperately as we are.
But c'mon guys, then next innovative technology that will alter our fuel dependencies has been announced every two or three months for decades now, and nothing's really changed. I'm jaded and tired and want to see something happen for really real now. Before I die. Of old age.

This seems a little too good to be true. Of course I say that without knowing any of the science, but it seems like a cold fusion/perpetual motion kind of dream.

As I understand it a major practical issue with this kind of thing (e.g. oil-producing algae) is efficiently removing the hydrocarbons so that the organisms don't choke on their own waste yet at the same time leaving the organisms behind and intact to keep producing. That may be easier to do with bacteria than algae, since they're simpler and presumably faster reproducing.

Well, no, there's also 'suitable light conditions,' per the patent.

Indeed, the company describes its manufacture of fossil fuels as “artificial photosynthesis.”We only need CO2! And sunshine, like solar power does.

Holy crap. This actually looks like it might be the real thing.
Any scientists in the house? Could this actually represent a solution to our energy source problems? How does this stack up? It uses waste carbon in production, so does that mean it's a net carbon sink?
$30 per gallon of diesel is pretty cheap, isn't it? They claim to be able to produce diesel at that price forever with this technology.
I mean, I've seen overblown claims of this kind before. But this has a different feel to it. Experts?

No. Burning the fuel releases water and carbon dioxide back into the atmosphere. Nothing gets 'used up'. That's the point of the whole thing.

You mean no significant particulates? Because there's going to be plenty of carbon, but it should be basically carbon neutral as the released carbon is captured by the bacteria again, more or less.

Aren't there lots of patents for things that don't actually work?
In theory, no, as utility is a requirement for patentability, so if it's non-functional it's not valid. The patent office does not usually demand proof of utility except for obvious things like alleged perpetual motion machines. That said, the proof is in the pudding, and if the company can't show working prototypes then they aren't going to get significant investors. And if it doesn't work they won't make any money. And of course having a patent on something useless doesn't really hurt anybody else since why would anyone infringe a useless patent? So it's really a non-issue.
Wasn't the patent office pretty much gutted so that anything that's paid for gets through, whether it's reasonable or not?
The US Patent Office is entirely paid for by applicant fees and patent maintenance fees. It can't really be gutted except by a sudden decrease in the number of applications (and by a lot of issued patents going abandoned, which means fewer maintenance fees paid). There was recently a slight budget crunch because the recession resulted in such a decrease, but Congress allocated some money to make up the shortfall. This was actually a good thing because Congress has skimmed nearly a billion dollars off of the Patent Office budget over the years from years when the Office has taken in more than it spent.

Right, but this would solve the storage problem. Hydrocarbons are a lot more energy-dense than batteries, cheaper to store and maintain than both batteries and (I believe) hydrogen, and there's already an infrastructure in place to handle hydrocarbons.
Besides, isn't everything, like, solar power, man, like, in the end? I mean, have you ever really looked at the sun, man?

There's no shortage of water in most places, just potable water. If they can use contaminated or salty water, which is one of their claims, then it ought to be fine. There's a lot of salty water in the world.
It's industrial processes that require clean, drinkable water (e.g. many IC production operations) and thus compete with people for that limited resource that are the problem.
But if you can do your industrial process with seawater, and you're not horribly contaminating it in the process, you can pretty much go nuts.

It must be carbon neutral unless there are carbon inputs besides CO2 from the air.
Once it's up and running any of the energy needs of the process could be fed by the output.

Well, that seems to produce a lot of oxygen, too -- regular photosynthesis takes water and carbon dioxide and creates CxHxOx (sugars) with a little water and free oxygen as 'waste'. It sounds like these guys made/discovered/altered regular photosynthesis to avoid adding oxygen to the mix and excrete just CxHx. Where does the excess oxygen go? Well, either which way, it's not a horrible byproduct of the system. I like oxygen, for the most part.

In the sense that it is a miracle energy source which will solve our woes, this won't happen. It may have utility in that it will enable civilization, for better or for worse, to stay on the Oil Teat for a little while longer.
If it weren't for the pesky carbon dioxide problem and all of the waste heat, liquid hydrocarbons are a not-bad way to store energy. Energy density is through the roof as compared to anything that isn't radioactive. Beats flywheels. Pourable, versus the slow battery charge times (for all of that "oh carbon nanotubes are going to make charging really fast now" stuff I'm still waiting for it to hit the market).
I think, though, that if this did pan out, we'd just use that extra time to go on ignoring the situation rather than saying, "Wow, we have a little breathing space instead of blindly panicking. Let's work on ultracapacitors and nuclear isomer energy storage while we make new, safer nuclear designs and start humping out solar panels like they're vinyl siding."

It uses waste carbon in production, so does that mean it's a net carbon sink?
Well, if you took the hydrocarbons produced and locked them away in barrels forever and ever, it would be a carbon sink. But since the point of producing hydrocarbons would presumably be to burn them at some point, producing CO2, it's not. Still, if it works as claimed (and that's a very big if), it would be pretty close to carbon-neutral.
Aren't there lots of patents for things that don't actually work?
Yes, the patent office does not determine whether an invention actually works as claimed.
Wasn't the patent office pretty much gutted so that anything that's paid for gets through, whether it's reasonable or not?
I think you're conflating separate issues here. The US patent office has not tried to determine whether an invention works as claimed in a very long time (if it ever did — I'm not even sure of that). It is supposed to determine whether an invention is new and non-obvious. They've been criticized for not even doing a very good job of that, especially in recent years, but it's still far from the case that every patent applied for gets granted. Even so, whether an invention is new and non-obvious (what the USPTO is at least supposed to be checking for) is a separate issue from whether the invention works (not really USPTO's job).

This is pretty straightforward. Converting cattle slurry to methane via anaerobic digestion is pretty well established as a working technology, and once you have methane then the process for converting to synthetic fuels is known science, albeit that it is too expensive to use currently.

On the contrary, patent examiners (the people at the patent office who decide whether to allow applications as patents) give out a lot of bogus rejections of applications instead of allowing stuff that is borderline patentable. Apparently, they can get in trouble for a bad allowance but not for a bad rejection. I have been filing a lot of appeals of these bad rejections.

Easy enough to check. Put a large sample of the bacteria in a tank full of ordinary sea water. Check on it in a few months or years and see if any of the oil-producing bacteria are left. My guess is that they either die off completely or mutate-away the oil-producing genes.

From the patent Jedicus linked: they've hacked a cyanobacterium (aka blue-green, photosynthetic, algae) and replaced a synthase with something that I guess eventually produces hydrocarbons.
This particular bacterium has both marine and freshwater strains, so presumably their tweak can apply to either.

The US patent office has not tried to determine whether an invention works as claimed in a very long time (if it ever did — I'm not even sure of that)
It used to require the submission of working prototypes for inventions that were amenable to such prototypes (mechanical ones, mostly, as you'd imagine).
Yes, the patent office does not determine whether an invention actually works as claimed.
To be strictly accurate: it will ask for a prototype or other proof of effectiveness in the case of really outlandish claims: perpetual motion machines, generalized 'cures for cancer' (i.e. all cancers), that kind of stuff. But most stuff gets a pass on utility as long as it has some alleged usefulness and passes the sniff test for functionality.

Ok, so biofuel from photosynthesising micro-organisms isn't really news. Using waste carbon dioxide from existing power plants isn't either. It has been shown many times that this works... sort of. The really critical numbers here are all to do with yield and scalability.

There's no such thing as ordinary sea water, though. You'd need samples from around the world, especially from locales where there are heavy outflows of various mutagens from human industry. And you'd want to keep a nice UV light on it.
And then you'd have to be willing to gamble that your few years and handful of tanks would be as good at recreating evolution as all of the oceans and, say, ten thousand years might be. And that lateral gene transfer might not shuffle this trait around elsewhere. As a trait, it might not be wholly a burden, given the utility of biofilms. "Hey, check this out guys, I can make an oil slick!" might be something handy for some bacteria.

But seriously, it is an interesting announcement. Going to take a fair bit of further explanation and scrutinizing before I'd get my panties in a bundle over it. They will have to pretty rigorously show that it is safe, and poses no harm if accidentally released, in a wide variety of settings. Not just saying.. oh well it will be out-competed, blah blah blah. History is chock full of idiots who thought like that and introduced, on purpose or accidentally, different organisms to non native ecosystems with disastrous effects. So, yeah, I fully understand that at this stage it seems unlikely to be able to survive in the wild. But I want a good sight better than "unlikely". No fucking possible Ice-9 scenarios eh?

Okay, so we put together a few hundred bioreactors with samples of sea water from all over the world, some with extra UV lights, some without.

I don't think we should be terribly worried about problems ten thousand years down the road given the impending doom of peak oil. But anyway, I think we can be at least as sure about the safety of this bacterium as we are about a lot of other dangerous stuff we do. It doesn't have to be perfectly safe forever, just worth whatever risk there might be.
"Hey, check this out guys, I can make an oil slick!" might be something handy for some bacteria.
It would not surprise me if there were already bacteria capable of producing oil. My guess is that they don't produce a lot of it, though, and the extra energy needed to produce more is heavily selected against.

Isn't it possible to design some set of genetic switches into these bacteria, so that they can't survive long enough to reproduce in the absence of some particular set of artificial living conditions? An approach like that could minimize the risk of contamination to the point it becomes insignificant. If the bacteria depends absolutely on certain artificially-created conditions (conditions not occurring in nature) being met to thrive, then there's no problem.

Probably still worth the risk, though. True, this isn't nuclear isomer energy storage or even a practicable thorium reactor, but it's a break; good lord, do we need one.

More bio-fuel bullshit
They claim 20,000 gallons per acre (I assume per year). That's 4.9 gallons per square meter per year.
They use photobioreactors whose typical costs are $150 per square meter.
So their capital costs are $30 per gallon, or $6 per gallon if depreciated over 5 years.
That's before any operating costs (like recovering the oil, paying employees and power bills) let alone making any profit.
I'm not a biochemist, so I don't know if their 20,000 gallons claim is bogus, but I suspect it is wildly optimistic.

This is pretty straightforward. Converting cattle slurry to methane via anaerobic digestion is pretty well established as a working technology, and once you have methane then the process for converting to synthetic fuels is known science, albeit that it is too expensive to use currently.

And water: whether fresh, brackish or salt.
The only thing more scarce than oil these days seems to be water. So good luck with that.
If they can use salt water they can take the water from the ocean. I've been led to believe that there is a drop or two extra there. Besides, isn't water one of the by-products of the combustion process?
If it produces diesel fuel, it's clean burning, right? No significant carbon output from the engine?
One would think that, as long as you can capture the carbon somehow (maybe it just pulls it from the atmosphere?), the production cycle could get close to being carbon neutral. You would burn the fuel, produce carbon dioxide and water, then use those to make more fuel. It couldn't make as much fuel as you started with but it would recycle what it could.
It isn't really perpetual motion though it really seems like it. You're basically turning energy from the sun into petroleum based fuel. If it works and it scales up well enough, it really would be game changing.
It seems like it should work in theory at least. The energy to make it all work comes from the sun and it is based on existing biological processes. Any biochemists out there that can tell us if this could work?

I will believe it when I see it. People have been trying to use bacteria, algae and even some higher plants to produce hydrogen, fatty acids, and hydrocarbons from sunlight and carbon dioxide for almost two decades. All of these systems tend to be very, very finicky. The systems used to produce the fuel, Joule's is pretty typical, have proven to be very, very susceptible to poisoning. These organisms produce waste products and decay products in addition to the hydrocarbons. After a while these systems are full of dead organisms and wastes, in a wet, aerated environment. The wastes themselves may poison the organisms; nothing likes living in it's own foulness. In addition, these are perfect conditions for invasive microbial growth. It's impossible to make a completely sealed system as air has to come in, which means that spores and encysted microbes can too.
These problems are will be very familiar to anyone who has ever run an aquarium.
This is the hard problem that no one has been able to crack so far: growing the organisms from more than a few cycles, at fuel high productivity. There are many organisms that would be very productive fuel generators: common duckweed, for example, can be as much as 50% vegetable oil, which directly converts to biodiesel and can be reformulated to gasoline. The problem is growing it sustainably.
If Joule has cracked this problem, that's a major advance. If they've bred a strain which can spit out hydrocarbons instead of fatty acids or triglycerides, say, then that's much less interesting. There are half-a-dozen or more startups busily burning through VC money with similar IP. Running a stable production system is the really hard problem. The particular organism, and even the particular fuel it produces, whether fatty acids, alcohols or alkane hydrocarbons, isn't really that important. In quantity, any of these could be converted or used as a liquid fuel.

Here's an ugly fact: hydrocarbons are bascially the most efficient, simple, and safe means of storing energy. They're what life itself uses for energy storage. We're never going to top them on a practical scale—not within the next twenty years, and maybe not at all. Hydrogen ain't gonna do it, and batteries won't either. Not by a long shot.
This is honestly one of the best bets we have for sustainable energy production, folks. Not necessarily this particular venture, but the general idea: biofuel production from microorganisms. Ignore the projected numbers, which are no doubt overly-optimistic. New technologies always take more money, time, and effort than expected. But the principles are more than sound. It's one of the few energy technologies that has a fighting chance of being a primary replacement for fossil fuels.

Dodecane is dodecane is C12H26, no matter if it comes out a bacteria's bum or from distilled dinosaur. Aside from sulphur inputs, the pollution from diesel combustion is more a function of the engine or power plant it burns in than the fuel itself. Particulates (PM10, PM2.5) will still be produced. Nitrogen oxides (NOX) will still be produced. Those happend because of the combustion thermodynamics of the engine. Trucks will still need urea reactors or some other activated filter to deal with NOX. Diesel fuel will still burn the same way, and still produce the same combustion products.

Oh, bullshit. Nobody, and I mean nobody, uses hydrocarbons to store energy, because hydrocarbon conversion efficiencies are crap. Sure, we're happy to burn it at 25% efficiency when there's an endless supply spewing out of the ground. It's a very convenient energy source. But no one actually converts energy into hydrocarbons for storage. End-to-end efficiency would be in the single digits. Good lithium-ion batteries, on the other hand, are over 90% efficient.

From the Joule FAQ: We estimate our costs for diesel to be as low as $30 per barrel equivalent.
Some weasel words there, but oil today is running between $80 to $90 USD per barrel, so that's roughly a third of present prices.
I say weasel words bcause a barrel of oil isn't a barrel of diesel. Depending on the source oil and the refining technology used, the yeild on crude for diesel is typically about 30% to 50% of the barrel. That is a third to one half of a barrel can be made into light fuels, gasoline, kerosene and diesel. This number goes up with better refining and processing technology and down with the poorer, heavier sources of oil now being extracted.
Given that, their actual per barrel cost is probably in the $60 to $90 USD range, but that's "per barrel equivalent" to two barrels of oil.

You may be able to get 90% of the energy out of a Li-ion battery that you put into it, but there are hidden costs associated with manufacturing and maintaining them. Batteries do not last indefinitely, they're relatively expensive to produce, and you'd need a small warehouse of them to equal the energy you can store chemically elsewhere.
I agree that using, say, a solar panel to produce hydrocarbons would be pretty inefficient. Instead of thinking along those lines, the better analogy to me would be comparing it to alcohol-producing yeast (another hydrocarbon, by the way).

Oh, bullshit. Nobody, and I mean nobody, uses hydrocarbons to store energy
Everybody uses hydrocarbons to store energy. You're more than likely doing it right now. I know my own body has a particular penchant for doing so. The problem is that we don't have technologies capable of reproducing this feat. That's what ventures like this one are trying to change.
In terms of energy conversion, you're right. Batteries are a much more efficient means of storing energy, at least compared to burning fuel rather than metabolizing it. The problem is energy density: batteries don't come close to comparing. Nor can they hold energy in a stable fashion for very long. Nor do they have long operational lifetimes. Nor are they cost effective on large scales. A lithium ion battery works great for small electronic devices, but they just don't hold up to high energy applications. Which is why, when the power goes out in a hospital, the diesel generators come on rather than a battery bank.

Technically, terrestrial biology uses carbohydrates to store fuel, as either complex sugars and starches or as triglycerides and/or fatty acids. I don't know of any organism that actually uses hydrocarbons, CNHM-type compounds for energy storage. Petroleum is produced by non-biological degredation under high heat and pressure. Organisms, by and large, don't make pure hydrocarbons.

Rats, dephlogisticated (and what an apt handle for this discussion) got there even as I was doing the research.
But have a look at this graph anyway. This is why there are effectively no electric cars or planes - batteries have a tiny energy density compared to petrol - and why hydrogen power is such a pain.
Petrol, and its various hydrocarbon pals, hits the sweet spot for portable energy storage. The only other stored energy thing that'll get you across the Atlantic in any kind of style is nuclear.
Energy you don't have to store is often better, but that's hard because of things like night, winter, windless days and Tesla not actually coming up with wireless power transmission.
I think my favourite energy source, which I read about as coming within twenty years much more than twenty years ago, is orbiting powersats in permanent sunlight, beaming microwaves down to huge rectenna farms. Who knows, with the current remarkable rate of development in PV, someone might write another article predicting them within ten.

You're absolutely right. I was using the terms interchangeably to make a point; carbon-based fuels are universal and enormously efficient. For those who might be confused as to the difference, both hydrocarbons and carbohydrates use carbon-hydrogen bonds (and to a lesser extent, carbon-carbon bonds) to store energy. The difference is that carbohydrates also include oxygen, which make them more soluble in water (and thus more easily used by the body).

That's just storing hydrocarbons, not energy in general. It's basically just the fossil fuel supply chain. Totally inapplicable to any other energy source.
there are hidden costs associated with manufacturing and maintaining [batteries]
Clearly this puts batteries at a distinct disadvantage to oil, which has none of these drawbacks.
Batteries are a much more efficient means of storing energy
More than an order of magnitude more efficient:
1) Solar cells are more efficient than photosynthesis.
2) Charging a battery is more efficient than building fat.
3) Discharging a battery is more efficient than burning fat.
Solar panels and batteries are much, much more efficient at every step in the process. And I'm not even talking about space-grade solar cells and laboratory toys. Even cheap thin-film panels are more efficient than the best photosynthesizer (sugarcane, I think).

Isn't pure oxygen extremely flammable, though?
No. However, many things are extremely flammable in pure oxygen.
More importantly, though, these wouldn't create oxygen out of nothing. They wouldn't convert the atmosphere into pure oxygen. It's not as if these are King-Midas-bacteria that turn things into oxygen instead of gold (though the idea is just as absurd).
They would take carbon from the carbon dioxide in the atmosphere, and hydrogen from water, convert those into hydrocarbons, and convert the oxygen atoms from the carbon dioxide and hydrogen into molecular oxygen. And for all the trouble it causes us, there's relatively little carbon dioxide in the atmosphere compared to the amount of oxygen that's already there. (20.95% O2 but only 0.039% CO2 by volume, if Wikipedia is to be believed.) And while there is a lot of oxygen in, say, ocean water, the amount used there is limited by the CO2 available.
Even if these soaked up all of the CO2 in the atmosphere, at worst the oxygen content of the atmosphere would increase from 20.95% to about 21.02%, at worst.
Now that I think of it, removing all the CO2 from the atmosphere is a nightmare scenario for other reasons (1. greenhouse gases work both ways; too little CO2 = another ice age? 2. No CO2 = nothing for plants & other photosynthetic organisms to grow on; food chain collapses) but things bursting into flame is not one of them.

The problem is energy density: batteries don't come close to comparing.
They're good enough today, and they are constantly improving.
Nor can they hold energy in a stable fashion for very long.
Self-discharge is a couple percent per month.
Nor do they have long operational lifetimes.
Compare it to a typical gasoline car:
200k miles / 40 mph / 24 hours / 30 days = 6.9 months
200k miles / 30 mpg / 15 gallon tank = 440 cycles
Lithium batteries can beat those figures.
Nor are they cost effective on large scales. A lithium ion battery works great for small electronic devices, but they just don't hold up to high energy applications. Which is why, when the power goes out in a hospital, the diesel generators come on rather than a battery bank
That's only because the hospital didn't have to fill the generator tanks from a renewable energy source.
The original comment I replied to stated that biofuels were our best bet for sustainable energy production and that more traditional technologies like batteries were doomed to fail.
That's crap. Today's solar cells are more efficient than any photosynthesizer. High-end solar cells are more efficient than the maximum theoretical efficiency of photosynthetic metabolism. Our batteries are nearly perfectly efficient. They can deliver enough power to run a high-performance sports car. They hold enough energy to cover nearly everybody's transportation needs. All this stuff is available right now, and it works great! It's commercially available, and not outrageously expensive.
But nah, let's pin our hopes on a tiny startup with a patent and a clipart website. They're our only hope!

The hydrocarbon / battery debate is off the point. What no one is doing is taking kinetic energy and using that to make hydrocarbons, and then burning those hydrocarbons to get their energy back.
If you want to factoring in the weight of the battery for comparison, you've pretty much reached a point where you need to start factoring in the power need of the application, the weight of the engine in a hydrocarbon fueled system and so forth. Without that you might as well be looking for venture captial to start making MP3 players powerd by little tiny two cycle engines.

I agree that the battery/fuel debate is off-topic. I'll concede the point on total-cycle efficiency. As for applications, it goes without saying that both Li-ion and hydrocarbons have their niches, and despite your protests to the contrary, one cannot effectively replace the other. Again, for high-energy applications like vehicle use, Li-ion batteries just don't compare to hydrocarbons—not in terms of energy density (1.30 MJ/L versus 35MJ/L for gasoline) or lifetime (your analysis ignores degradation due to time, which is roughly 20%/year for Li-ion). Nor in terms of cost, but you may fairly argue that gasoline is artificially cheap insofar as it isn't renewable, and I won't go so far as to argue the costs of a technology that hasn't been invented yet.
I don't think we can pin all our hopes on any particular technology. And it may surprise you to know that I'm actually a huge supporter of solar energy, especially solar-thermal. But batteries (no matter how they are powered) are not in any danger or supplanting hydrocarbon fuels for certain applications. Not any time soon.

This is not radical new secret technology, quite a few companies ahve been working on this for some time. If/when Joule Unlimited get this to market, they'll have first mover advantage, but tehre's no special secret magic to this process. I know of people that are working on this in Australia.
The real issue with this, that I am very surprised hasn't come up yet, is that the process requires concentrated CO2, not just the ~390 ppm that's hanging around in the atmosphere. Scrubbing the atmosphere to get your concentrated CO2 wouldn't ever work, it would be entirely self-defeating (analogous to a perpetual motion machine) so of course you'll use 'waste' CO2 which is basically going to be the tail pipe of a fossil fuelled power station.
What this means is that you are still burning coal or natural gas, and you can only get two bites of the cherry. While it's pretty neat to get up to a 50% reduction in CO2 emissions (depending on your chimney scrubbers), this isn't going to be nearly enough to avert catastrophic climate change. The only way to avoid that (unless it's already too late) is to stop burning coal entirely, and only use NG as a transition fuel.
So it's good news, but it's not a game changer by any means.

Scrubbing the atmosphere to get your concentrated CO2 wouldn't ever work, it would be entirely self-defeating (analogous to a perpetual motion machine) so of course you'll use 'waste' CO2 which is basically going to be the tail pipe of a fossil fuelled power station.
What this means is that you are still burning coal or natural gas, and you can only get two bites of the cherry. While it's pretty neat to get up to a 50% reduction in CO2 emissions (depending on your chimney scrubbers), this isn't going to be nearly enough to avert catastrophic climate change. The only way to avoid that (unless it's already too late) is to stop burning coal entirely, and only use NG as a transition fuel.
So it's good news, but it's not a game changer by any means.

wilful: But if you get this working on a large scale, economics and all, then you can burn the captured hydrocarbons in the power station rather than dig up coal, gas etc. Displace your electricity sector emissions (about 25% of emissions in western countries), switch your heating to electrical (direct, maybe with heat pumps long term, typically close to 50% of emissions are currently heat) then that's big savings on CO2. Electrically powered vehicles and/or biofuels to displace emissions in the transport sector. Would be odd to burn oil for electricity again, but its primarily the economics that stopped that.

biffa, sorry, but that makes no sense whatsoever. You still have to dig up the coal to create electricity, you run the waste through the algae scrubbers to create some biodiesel, the only net win is the transport fuel.
You cannot possibly run the biodiesel back through the power station. Apart from the fact that a new power station would be required, that starts turning into magic. If they made this absolutely as closed loop as they could, all they're doing is using photosynthesis to convert CO2 into fuel. In which case, I give you this.

Fossil fuel power stations are not the only significant sources of CO2. Cement plants also produce a lot, about 3.4% of global CO2 production. Globally about 829 million metric tons of CO2 is produced as a byproduct of cement production every year. That's ~348 million metric tons of carbon, enough for roughly 2 billion barrels of fuel. That compares to 30.7 billion barrels of oil consumed every year. 6.5% of world oil consumption being carbon neutral wouldn't be half bad. Is it enough all on its own? No, but it would put a big dent in things.

jedicus, wrong on a few accounts, sorry. Fossil fuel power stations really are the main game, ask James Hansen. The 3.4% figure isn't of total emissions, it's of fossil fuels and cement.
There's no suggestion from this technology that cement production is amenable to carbon capture. Is it? I don't know. Also, I can't imagine this technology is 100% efficient in conversion, it would have embedded energy costs of its own.
Oil consumption is rising.
Cuts of 95 percent or more are required for first world countries. A 6.5 percent cut (though likely to be far less for the reasons above) doesn't take you terribly far at all.
I'm not sceptical about this, I'm happy to see it develop, it's just not going to be any sort of a panacea at all. TANSTAAFL.

Fossil fuels + cement is pretty close to total emissions. Iron and steel production is another major source and it drops off really fast after that.
There's no suggestion from this technology that cement production is amenable to carbon capture. Is it? I don't know.
The patent specifically suggests capturing CO2 from cement production facilities. It's on a pretty short list, after concentrating it from the air and nabbing it from fossil fuel burning facilities. So in the absence of other evidence I'm going to take that to mean yes.
it's just not going to be any sort of a panacea at all.
Hence "Is it enough all on its own? No, but it would put a big dent in things."

FTFY. Check the wee jagged line in the first data point, compared to the scale.
Really I guess the quibble is over "big". I think it will be an insignificant tiny little bump. And it's not really radical. But more power to 'em.

Yes, and of the remainder cement production is one of the few major sources. Really you're making my point for me, which is that the 3.4% figure was close enough to '3.4% of all carbon emissions' as makes no difference.

nah, my point is that 3.4 percent (or a figure less than that) is closer to zero than it is to 95%.
Not that I want to get all fighty over it, it's just that this technology aint going to amount to a hill o beans.

KokuRyu writes "It seems pretty irresponsible to regard any system on the planet, including the oceans, as an infinite resource we can exploit to solve problems created by our own greed and inefficiency."
The emissions from burning the algae produced fuel is going to return the water to the oceans eventually either as rain or fresh water input. Unless this process is so successful that we end up storing significant amounts of fuel and thereby sequestering the water it can't make a dent in ocean levels.

Late to the party here, but as has been noted a few times, there are lots of groups working on similar approaches. Issues include maintaining the microbial ecosystem of your precious engineered bugs, and conversely, worrying about them getting out in the wild. That said, I note that the Joule folks are woefully undercapitalised compared to these folks.

What's the production rate of the largest microbial biofuel demonstration project? Are there any?
Look, it's not that I'm skeptical of the science, just the medium-term practical utility. Looking back on the history of solar panels, it took a long time before they became practical for terrestrial power generation.
The first big commercial market for solar cells was in communications satellites, starting around 1960. Ever since then, the space industry has been pouring money into improving solar cell efficiency and reliability. That's 50 years of commercial, government, and military funded photovoltaics research. It's taken billions of dollars and many thousands of patents to develop solar cells suitable for terrestrial power generation.
So with that context as a gauge, what is the current state of microbial power generation? How far along is it in the journey from laboratory to power station? Has microbial generation found its "communications satellite", its first commercial application? Are there any cozy, high margin markets where the technology can develop and mature for the next 50 years?
