$1/Gallon "Green Gasoline" In Sight
mattnyc99 writes "We've gotten excited here about the startup that claims it can make $1/gallon ethanol out of anything from trash to tires. But we've also seen how cellulosic ethanol is a better option, and how ethanol demand in general is only adding to the worldwide food crisis. So what about $1/gallon gasoline? NSF-funded researchers at UMass Amherst just completed the first direct conversion from cellulose using a new method of hydrocarbon refining, which they claim can be commercialized within 5-10 years and essentially make fuel out of anything that grows. Quoting: 'We already have the infrastructure in place to distribute liquid fuels. We're using them to power transportation vehicles today, and I think that's what we'll be using in 10 years and in 50 years,' Huber says. 'And if you want a sustainable liquid transportation fuel, biomass is the only way to go.'" The process is running at about 50% efficiency now; the $1/gallon figure is based on getting to 100%.
For the consumer or in some huge volume?
1 US gallon = 3.78541178 litre
Over here in Sweden the taxes put the gasoline price at something like 12.49-12.99/litre in this town right now according to a webpage.
Say 12.70 sek / litre * 3.785 = 48.07 sek.
8.36$ / gallon in the gasoline station.
So yes, people would gladly pay 2$/gallon here. In face people already pay almost 1.5 $ / litre for etanol/E85. (And we do have tax reduction / no taxes(?) on that.)
Well, I can't say exactly how long it will take to commercialize, but the company I work for, which may or may not have been mentioned in the article (wink) has a production-scale run of the catalyst scheduled for later this year. I wouldn't scoff too hard at a 5-10 year projection.
The 50% efficiency is how much of the biomass energy they can convert to the "high-octane liquid". Can they get to 100%? No...you cannot extract 100% energy from something, also the process that is getting you 50% yields will probably require much more energy then what you are doing right now.
Also does this $1/gallon figure account for the energy needed to raise/cool this biomass the 1000 degrees per second? Also the cost of getting the biomass? And the cost of collecting (and probably liquifing/straining/etc this biomass. Is this $1/gallon number include current tax rates for transportation maintenance? I have a funny feeling that that might just be the cost to actually execute the refinement assuming everything else was free.
I just bought a car that happens to take this E85 ethanol combo gas.
It dropped my mileage from city 22 to like 16, highway 30 to 22.
It was a little cheaper due to government subsidies ($2.77 vs $3.30 at the time), but it didn't come close to breaking even with the drop in mileage.
Overall very disappointed.
Where are the plug-in hybrids?
That's rough, but at $118/bbl, the cost of refined gasoline is somewhere about $2.50/gallon. The $3.50 you're paying at the pump includes distribution and taxes. So you'd pay $3/gallon for a fuel that stores only about 60-65% of the energy as the $3.50/gallon gas your paying now. Not really economical. At their theoretical 100% efficiency, it's about a wash, though you'll still have to visit the pump half again as often to fill up.
Is it just my observation, or are there way too many stupid people in the world?
When we can make affordable fuel out of trash, garbage, and untreated sewage, then trash, garbage, and untreated sewage will nearly immediately be in short supply. Cost of the raw material will increase, and make the finished product less affordable.
Pretty soon after that, we will cut down perfectly good trees for no other reason than to make liquid fuels. Darn. There goes the forest. And the parks, etc. Not so good.
It's just not that easy. But it's attractive, and will keep us until we can do the electric car thing and do away with liquid fuels altogether.
Maybe.
deleting the extra space after periods so i can stay relevant, yeah.
When I calculate my fuel mileage based on ONLY how much diesel I actually pay for, I get about 30-33 highway mpg in my 7900 pound 3/4 ton diesel truck.
Gasoline engines are a flawed design and gasoline/ethanol is a flawed fuel. It does have a place such as in motorcycles or small engines. I'll take my diesel powered vehicle any day of the week over some inefficient gasoline powered vehicle.
Truth. The premise of the third movie was that they couldn't get the Delorean up to 88 MPH since they had no gasoline.
I do wonder how much organic waste we are just letting go in the garbage every year now, though? I mean, millions of yards get mowed weekly (or more depending on where you live)....not to mention golf courses, stadiums, parks...etc. Then as someone said, we have tons of paper and boxes that are garbage each day. How about recycling most all of that waste paper into fuel?
I'd say at the start...that amount of ethanol, combined with the domestic oil reserves we have....could get us off the world 'grid' pretty quickly. Eventually..we could get off the fossil fuel altogether, but, this would be a huge stop-gap answer.
I wonder how much organic waste we currently just throw in the trash now, which could go for this type of ethanol generation? We could quit using corn for ethanol (well, except for consumption) right away too.
Now, if we could just do away with the fscking corn subsidies, and lift the sugar tariffs we could also kick the HFCS problems we have, get food prices back down a bit, and have real Coke with real sugar again in the US.
Light travels faster than sound. This is why some people appear bright until you hear them speak.........
This is being done/worked on. It's called Terra Petra "Black Earth" and is being developed for use in biomass gasification.
Basically you gassify carbonaceous materials such as wood or other biomass. Instead of allows all the biomass to be consumed in the process, you pull a portion of the charcoal out of the gasification stream and then disc it into the earth. Charcoal, being a fairly stable version of high density carbon will remain in this state for a very long time and in a sense becomes fertilizer for the soil (over time). Charcol is a more stable form of carbon than just raw biomass which will otherwise decay into CO2 as it rots
In fact, in the amazon, this has been going on for 1000s of years and is a way to make otherwise not so great tropical soils fertile.
Gasification combined with Terra Petra has the possibility of not only being carbon neutral, but carbon negative. If you gassify existing biomass (in particular the waste wood and garden clipping stream of most municipal wastes) you start out carbon neutral. The carbon in the waste stream is already destined to either be incinerated or 'mulched' which releases the carbon as CO2 either way.
If during the process of gassifying this biomass stream, you extract a portion of the charcoal that is created, you can then sequester it in the soil. Thus becoming carbon negative to the extent you pull from your gassifier. The trade off is that you have less carbon to convert to CO for use as a producer gas.

The only drawback is that the landfills are being refilled with ash, and eventually will run out of room again.
If you trashed the CFLs, the amount of mercury released would be less than the mercury released by coal-fired plants to power the equivalent in incandescent lights.
And CFLs can - and should be - recycled, so no mercury is released except for the occasional broken bulb. If you break one, you just take some simple precautions to clean up. They have about 1/100th of the mercury in a old thermometer, the type everyone had in their house not very long ago.
Environmentally, mercury in CFLs is a very very small issue.
And an electric car powered by a coal-fired generating plant still emits much less pollution than a gasoline car.
So what's your point?

Post to undo accidental modding. A long set of dropdown boxes that take effect immediately with no way to confirm or change...what could go wrong?
(Or have I missed something?)
I figure a better way to store hydrogen would be with around a chain of carbon atoms ;). There's a lot of hydrogen you can store that way.
Either we burn the result, or we figure out how to build filters, fuel cells and catalysts that can handle the result in an environmentally friendly way.
A big benefit of having an electric subsystem is for the regenerative braking.
The benefit of sticking to hydrocarbons would be backward compatibility.
One of the problems is if we use rare catalysts - there might not be enough to go around to put in every vehicle (assuming a believable catalyst recycle rate when the vehicle is scrapped).
Actually, you're wrong. That's a POSSIBLE consequence, but not a necessary one. The reactors do not need to be of a type useful for making weapons-grade material in order to be useful for making useful nuclear reactor fuel.
And the waste problem remains unsolved.The reprocessed waste has a half-life which at least seems manageable on a human time scale, and is not nearly as nasty in any case.
Skip uranium entirely. Go to an "energy amplifier", where thorium is hit with a proton beam. It's subcritical - pull the plug and it shuts down. It's proliferation-resistant, and it can even be used to burn up plutonium. And it produces a lot less waste.Per your source, This design is entirely plausible with currently available technology, but requires more study before it can be declared both practical and economical.
"You're right," Fisheye says. "I should have set it on 'whip' or 'chop.'"
Actually, quite a bit of the environmental cost of using steel or aluminum is related to the energy cost of refining it.
It would make more sense to stop making so much plastic shit than to recycle it. We can make compostable hemp plastics. No shit. You can make them with corn too, but corn is not a good feed stock for reasons which should be obvious.
Given that most of our energy comes from Coal in this country, you should be concerned about the energy cost issue.
"You're right," Fisheye says. "I should have set it on 'whip' or 'chop.'"
not sure where you pulled that from? Their seams to be one clean coal plant in the US, and with batteries not being exactly green, and a pure electric car costs more to run than the same car running on hybrid (if battery replacement cost is not subsidized.) Throw in all the radio-active emissions of coal plants (none in gasoline.)
It's very, very simple. Gasoline engines are very inefficient. Non-hybrids average less than 20% tank-to-wheel efficiency. Hybrids, just over. Fuel-burning power plants, 30-50% efficiency. Transmission losses, ~8%. Charger losses, ~7%. Battery losses, ~0.1% in Li-ion. Motor losses, ~10%. Do the math. I can give you several peer-reviewed studies on the topic if you're prefer.
As for batteries, you're just not up to date with the technology. These aren't lead-acid or nickel-cadmium batteries here. For example, my Aptera is to use lithium phosphate batteries. These last 10-20 years and are almost completely nontoxic. Their raw ingredients are things like iron, phosphoric acid (the same stuff as in soft drinks -- made from fluoroapatite, the same stuff as in well cared-for teeth, plus sulphuric acid, which is an oil industry *byproduct*), graphite, and even sugar (for the carbon binding). These aren't "in a few years" -- they're already here. They're becoming the new standard for cordless power tools, for example.
Considering low emission gas vehicles currently exhaust cleaner air than they take in
That's nearly always a myth promoted by the manufacturers. If you look at the actual numbers, they usually lower one pollutant by a tiny amount (say, particulate matter caught up in the air filter) while still emitting the other pollutants.
I just invaded Grammar Czechoslovakia and duped Grammar Neville Chamberlain; now it's on to Grammar Poland.
(and was used to make gasoline in SA),
The sentence should read: Is still used to make gasoline (petrol, diesel) in SA, and Qatar.
however it's not energy efficient, and i hardly believe that this process is either.
CTL and GTL is energy efficient. It is cheaper to manufacture gasoline from gas or coal than to pump it out of an oil field. SASOL (the company in SA that makes gasoline from coal and gas) has grown considerably during the high oil prices. Their stock price doubled in a year. They made huge profits at $40 dollars/barrel - imagine what they are making now. There were even calls for a special tax on this company (since it makes humongous profits).
Here is a stock chart for SASOL (on the LSE). As you can see, the stock price is 6 times what it was in 2004.
Just a side note, making cellulistic ethanol is a much harder and difficult beast â" it is more difficult (by a few orders of magnitude) than making ethanol from corn.
