These days it's easy to get productivity during recessionary times. You just keep laying off people and/or make those that retain their jobs work longer hours.
It didn't used to be like that. In the past, there was a lag between a downturn and when people actually got laid off. Employers would tend to put the workers they didn't need to work doing other things even if it was only sweeping up the place. Skill and experiance were valued and the employer also didn't want to have to train new workers.
Now the trend is reversed. A downturn provides the employer with justification for "rationalizing" the work force. Higher paid experianced workers as well as deadwood are let go, other workers fearing that their job might be the next to go are usually willing to work harder and longer. Productivity goes up.
Productivity is good for the bottom line; however, it doesn't guarantee jobs, the thing we need most right now.
On CNBC, they where talking about where American college students ranked internationally on math and science. I missed the actual rankings but based on PISA rankings in December the US was ranked 35th in science (out of 57 countries) and 21st in math. The math was up from 29th place two years ealier. Pretty good improvement but still the ranking was still pretty low imo.

Just another night's work for those guys not bright enough to get a real job, I guess.
Here's a very interesting article by Mark Perry, and a great graph, on how little finished consumer food products are influence by wildly gyrating Commodity Prices.
The Soperton, Ga fiasco was a big ol' "Gassification" project, the kind the government likes to fund, that I've said for quite some time was doubtful. There are a few other ones like it that will end the same way.
The ones that work are the "Enzymatic" processes. Inbicon built the first one in Denmark, and it's working like a charm.
Wood is, at this time, a non-starter. It's just too hard (pardon the pun.) Inbicon, and the future Abengoa plant in Kansas, use wheat straw. It works good, but isn't optimal.
Switchgrass, Miscanthus, corn stover, and cobs are optimal.
We'll end up getting about 5 Billion Gallons/yr from corn stover, and cobs, and then move on to switchgrass, miscanthus, etc.
Sweet sorghum might, also, make a contribution some day.
If a serious person asked me for the energy/cost inputs into cellulosic I would do it, Doug. But I'm quite sure you are just looking for a chance to be snarky, and aren't the least bit interested. So I'll save myself the trouble.
But, in case someone might be curious, the producer will need a price of about $2.25 - $2.50 to make a decent profit with enzymatic cellulosic ethanol. (Without Any Subsidies)
Wholesale ethanol is selling for $2.61 gallon, today.
David Walker, ex Comptroller of the Currency was on Squawk Box this morning. He stated that the Mean Effective Tax Rate for the Top 1% of all earners was 18.2%.
Last Year, GE made $14 Billion, and paid NO Federal Income Tax.
When the Republicans start addressing those things, I will start listening again.
When the first Republican leader stands up and says, "That $100 Billion/Yr in Afghanistan is Stupid" I'll start paying attention to their rhetoric again.
When the first Republican leader says, "Social Security has $2.6 Trillion in the Trust Fund, and is running a Surplus virtually every year, including this one. Why do we continue hammering on That?"
When the first Republican (other than Grassley) says, "Shit, gasoline is at $3.83/gal, and going to God Knows Where, and global oil production is peaking, Why are we still Beating Up on Ethanol?"
I might start taking them for something besides self-serving fools.
When the first Republican stands up and says, "Gentlemen, why are we spending a couple of hundred Billion/yr in the Persian Gulf when 85% of the oil from there goes to Asia?"
"If a serious person asked me for the energy/cost inputs into cellulosic I would do it, Doug. But I'm quite sure you are just looking for a chance to be snarky, and aren't the least bit interested. So I'll save myself the trouble."
---
I am serious, Rufus, ...and don't call me snarky.
No need to go into details and numbers to start with Rufus: Just list some of the significant elements in the process that consume energy:
Why Doug? As much as I've posted, here, on the positive energy balance of corn ethanol, and the extreme uncertainty of the "hungry world" claims you still post that.
I'll just give you one little tidbit, Doug. After the cellulose is removed, mostly from enzymatic action, there is, left over, an enormous amount of lignin.
That lignin is burned, or run through an anaerobic digester to produce biogas which is then burned, to provide, not only all of the process energy for the plant, but, also, to produce electricity for sale onto the grid.
A 10 million gpy plant (approx the size I recommend) will not only power itself, but will sell approx (depending on feedstock, process, etc) 100,000 Megawatt/hrs onto the grid. That would run, maybe, 4,000 homes.
So, the process would use NO nat gas, or electricity, and would supply 10 Million gallons of ethanol, and enough electricity for a small town.
You will need about 10,000 acres in the South East to end up with 10 Million gallons.
Switchgrass is a perennial, and, after the first year there is very little (usually, no) fertilizing, and there is no cultivating. It's, basically, plant, and harvest every year for nine or ten years.
No heavy tractors, or machinery - a small, gas-engined tractor (might as well burn ethanol in it,) and light equipment. Maybe one gallon per acre (we're looking at about a 1,000 gal/acre/yr yield, remember.)
And, yes, dumbfuck, Corn Ethanol has a Positive Energy Balance. Even the most strident of its critics now recognize a 2.3:1 btu balance. And, those are nat gas btus, not petroleum btus.
There is only about 1 (often less) petroleum btu in 20 btus of ethanol.
Now, here's what scares the Oil state Republicans to death.
The corn ethanol plants will, in the fairly near future, have a companion plant processing corn stover, and cobs.
This companion plant will provide all of the process energy for itself, and the corn ethanol plant (thus taking away the energy balance argument, once and for all, even for the dumbass republicans,)
but will be selling electricity by the scads all over the Midwest, severely pissing off the coal state Pubs, AND dems.

Affirmative action + affirmation of feelings = Negative Correlation Coefficient of Ranking
And, as for the hungry poor peepulz: Let me say it again; Poor peepulz don't eat field corn.
Poor Cows eat field corn, and are, in turn, eaten by Rich Peepulz.
Also, the Co-Product of ethanol is Distillers Dried Grains (DDGS)
You get half of your Feed Value back in DDGS. So, instead of using 4 billion bushels of cattle feed you actually use 2 billion bushels of cattle feed.
Approx 2% of the world's grain output goes into ethanol.
However, in the process of going from four cents/lb to eight cents/lb (how many pounds of corn do you think YOU can eat in a day?) you have given 1.7 Billion malnourished subsistence farmers a potential "cash crop,"
which could very easily lead to "Less" malnourishment, not more.

But, in case someone might be curious, the producer will need a price of about $2.25 - $2.50 to make a decent profit with enzymatic cellulosic ethanol. (Without Any Subsidies)

Ruf, you get upset when we question you on your numbers or on whether cellulosic ethanol is currently ready for prime time. Admittedly, no one here puts in the time you do on this subject. Yet every day there are articles put out that dispute one or more aspects of your numbers or view on this subject.
There is no point in you getting upset when some of us ask to see some evidence, i.e. substantial commercial producion and usage.
You laughed at my definition of short-term as a year or two. What is your definition of short-term? And given that definition, when do you project we will see cellulosic ethanol commercially available and used in large quantities without (as you noted above) subsidies?
You snicker and mock us poor bumkins for 'not getting it'; however, you have to admit it's not all that straight forward.
For instance, you state "The ones that work are the "Enzymatic" processes. Inbicon built the first one in Denmark, and it's working like a charm." Heck, I might know something about the enzyme guys but didn't know anything about Inbicon so I looked them up.
From what I can see this paper was put out by Inbicon in October, 2010. It purports to show the path to commercialization for their process. There are 15 slides in the presentation. Slide 4 summerizes the requirements they need for commercialization.
The first requirement is a ‘proven technology in place’. They say they have proven this through pilot and demonstration plant volumes completed late last year. The second requirement is a 'demand for end products'. The last is 'feasible projects'. These are covered on slides 12, 13, and 15.
I am going to posts comments on those slides separately because of blogger.
From what I can see, Slide 12 is just a general projection chart showing the projected growth in 2G ethanol between 2009 and 2015. You are probably a lot more familiar with what it is saying.
The only things I noted that were interesting was the the U.S. growth is all projected to be politically "targeted". I assume that refers to the current mandates through 2022.
Also, of note is that Brazil's total usage drops for some reason and that Inbicon is using BP figures for their baseline projections.
The most interesting slide in the Inbicon presentation (for me) was Slide 13 and to a lesser extent Slide 15.
From what I can see from Slide 13 and Slide 15, Inbicon is looking for subsidies, grants, loan guarantees, tax credits, and R&D/demonstration funding for as far as the eye can see. Maybe I'm missing something here.
In addition, looking at Slide 15 and Slide 12 together Inbicon seems to be saying that the projected growth in U.S. ethanol usage is driven by government mandate. That's understandable given the mandate is already in place through 2022.
However, they project a doubling of usage in the EU, that is dependant upon higher incentives being offered. Asia and Brazil also have a question mark next to them.
Slide 15 is on 'feasible projects'. It outlines ways projects become feasible. It lists the following;
Feasibility is possible through: 1. Cheap biomass (already collected) 2. Integration with power plant 3. Integration with anaerobic digester 4. Local incentives
Many of these get back to the problem of NIMBY that I have mentioned before.
For me there seems to be a lot of questions on the timing for commercial quantities of 2G ethanol. You usually dismiss these concerns as the rantings of a loon.
So my questions are,
1. Am I missing something in Inbicon's 'road to commercialization' presentation? 2. Does the presentation present a viable plan to get to commercialization? 3. Based on your expertise, when can we expect the commercialization of cellulosic ethanol to be implemented in significant quantities, without subsidies and incentives?
Cellulosic ethanol, in theory, is a much better bet. Most of the plant species suitable for producing this kind of ethanol — like switchgrass, a fast- growing plant found throughout the Great Plains, and farmed poplar trees — aren't food
crops. And according to a joint study by the US Departments of Agriculture and Energy, we can sustainably grow more than 1 billion tons of such biomass on available farmland, using minimal fertilizer. In fact, about two-thirds of what we throw into our landfills today contains cellulose and thus potential fuel. Better still:
Cellulosic ethanol yields roughly 80 percent more energy than is required to grow and convert it.
So a wave of public and private funding, bringing newfound optimism, is pouring into research labs.
Venture capitalists have invested hundreds of millions of dollars in cellulosic-technology startups. BP has announced that it's giving $500 million for an Energy Biosciences Institute run by the University of Illinois and UC Berkeley.
The Department of Energy pledged $385 million to six companies building cellulosic demonstration plants.
In June the DOE added awards for three $125 million bioenergy centers to pursue new research on cellulosic biofuels.
There's just one catch: No one has yet figured out how to generate energy from plant matter at a competitive price.
The result is that no car on the road today uses a drop of cellulosic ethanol.
The step that has perplexed scientists is the one involving enzymes — proteins that come in an almost infinite variety of three-dimensional structures. They are at work everywhere in living cells, usually speeding up the chemical reactions that break down complex molecules. Because they're hard to make from scratch, scientists generally extract them from microorganisms that produce them naturally.
But the trick is producing the enzymes cheaply enough at an industrial scale and speed.
The truth is, every problem associated with drilling for natural gas is solvable. The technology exists to prevent most methane from escaping, for instance. Strong state regulation will help ensure environmentally safe wells. And so on. Somewhat to my surprise, this view was seconded by Abrahm Lustgarten, a reporter for ProPublica who has probably written more stories about the dangers of fracking than anyone. In a comment posted online to my Tuesday column, he wrote that while the environmental issues were real, they “can be readily addressed by the employment of best drilling practices, technological investment, and rigorous regulatory oversight.”
The country has been handed an incredible gift with the Marcellus Shale. With an estimated 500 trillion cubic feet of reserves, it is widely believed to be the second-largest natural gas field ever discovered. Which means that those of you who live near this tremendous resource have two choices. You can play the Not-In-My-Backyard card, employing environmental scare tactics to fight attempts to drill for that gas.
Or you can embrace the idea that America needs the Marcellus Shale, accept the inconvenience that the drilling will bring, but insist that it be done properly. If you choose this latter path, you will be helping to move the country to a fuel that is — yes — cleaner than oil, while diminishing the strategic importance of the Middle East, where American soldiers continue to die.
Q, Everything is political. Exxon, and Shell own Oil Fields, not Corn Fields. They would Never, ever use a drop of ethanol if not forced.
How does this in any way answer the questions I raised above on the Inbicon post?
Everything is political? Of course it is. That's why the US is still paying oil companies subsidies they don't need. That is why the East Coast is fighting the West over government dollars for wind. That is why Bush and Obama pushed on electric, mandated it, and now why Obama is talking about taxing it. It is also the reason we have a mandate on ethanol usage. Don't even get me started on the influence of the 'greens' or local NIMBY concerns.
You proclaim ethanol is the way to go and cellulosic is the wave of the furture. Maybe. But then, you also constantly tell us ethanol is competitive. That it can be so without subsidies. Yet the CEO of the company you mention as an example of it "working like a charm" puts out a paper saying commercialization (if I read it right) is a little iffy and will depend on mandates, subsidies, tax credits, etc., etc.
When some here raise questions about your rosy perspective they are called dumbfucks and morons. You have a simple answer for everything. When rising food prices and resulting riots in the ME and Africa are mentioned, you talk about the corn content in a box of corn flakes instead of any mention of the supply demand effects of commodity shortages. You assume all that fallow land out there is just waiting to be tilled for switchgrass. You have a simple answer for everything like "we'll just build a generating plant next to it" ignoring local zoning and NIMBY issues.
When asked if it is so good, so competitive, cheaper than gas, why aren't we doing more of it commercially, you tell us it is "only" because of a plot by the big oil companies and the GOP.
Sorry, I'm not that credulous. Are some Republicans and big oil against ethanol? Sure. Is that the only problem ethanol has? I don't think so.
"The way I see it, whether the yields are 400 tons or 1,000 tons per unit, non of the land used or the cash flow required goes to Saudi Arabia.
Guess you'd rather send money the Saudi princes than to US farmers."
---
Just as Quirk complains about Rufus nipping and tucking at the truth to come up with a simple answer, you have done here:
A careful reading of Quirk's arguments and the articles I posted indicate that cellulosic ethanol is still a work in progress, and specifically awaits the development of industrial scale enzyme production.
Building out a national infrastructure before a commercial solution is found would be madness.

Also ignores the fact that unlike breweries and corn ethanol plants, cellulosic is not a simple operation that can be easily downscaled.
Being that this is the case, transportation and storage of LARGE amounts of feedstock becomes another limiting factor.
(instead of Rufus's small tractor, specialized equipment is used to stack and store, as is noted above.)

Doug, the link was to a chart giving the productivity numbers from 1947 to the present.

But, in case someone might be curious, the producer will need a price of about $2.25 - $2.50 to make a decent profit with enzymatic cellulosic ethanol. (Without Any Subsidies)
ReplyDeleteWholesale ethanol is selling for $2.61 gallon, today.

Well, dougo, the Ryan proposal will not pass the Senate. There will be another piece of legislation that will pass.
ReplyDeleteIt will not be the Ryan Budget Plan, guaranteed. The Ryan Budget Plan is rhetoric, not the finished product.

When the first Republican says, "Why did we just cut $220 Million from the Border Fence?"
ReplyDeleteI'll fall out of my chair.
When the first Republican stands up and says, "Gentlemen, why are we spending a couple of hundred Billion/yr in the Persian Gulf when 85% of the oil from there goes to Asia?"
ReplyDeleteI'll have a stroke.
Doug, the chasm of difference between what You want, and what your Republican heros in congress want is so Wide as to be Unbridgeable.
ReplyDeleteWhy are we still Beating Up on Ethanol?"
ReplyDeleteBecause Corn Based Ethanol saves no energy, and steals food from a hungry World.
"If a serious person asked me for the energy/cost inputs into cellulosic I would do it, Doug. But I'm quite sure you are just looking for a chance to be snarky, and aren't the least bit interested. So I'll save myself the trouble."
ReplyDelete---
I am serious, Rufus,
...and don't call me snarky.
No need to go into details and numbers to start with Rufus:
Just list some of the significant elements in the process
that consume energy:
I'm sure some here would find that enlightening.
Why Doug? As much as I've posted, here, on the positive energy balance of corn ethanol, and the extreme uncertainty of the "hungry world" claims you still post that.
ReplyDeleteI'll just give you one little tidbit, Doug. After the cellulose is removed, mostly from enzymatic action, there is, left over, an enormous amount of lignin.
ReplyDeleteThat lignin is burned, or run through an anaerobic digester to produce biogas which is then burned, to provide, not only all of the process energy for the plant, but, also, to produce electricity for sale onto the grid.
A 10 million gpy plant (approx the size I recommend) will not only power itself, but will sell approx (depending on feedstock, process, etc) 100,000 Megawatt/hrs onto the grid. That would run, maybe, 4,000 homes.
So, the process would use NO nat gas, or electricity, and would supply 10 Million gallons of ethanol, and enough electricity for a small town.
NOW, before you get the switchgrass to the plant.
ReplyDeleteYou will need about 10,000 acres in the South East to end up with 10 Million gallons.
Switchgrass is a perennial, and, after the first year there is very little (usually, no) fertilizing, and there is no cultivating. It's, basically, plant, and harvest every year for nine or ten years.
No heavy tractors, or machinery - a small, gas-engined tractor (might as well burn ethanol in it,) and light equipment. Maybe one gallon per acre (we're looking at about a 1,000 gal/acre/yr yield, remember.)
And, that's it.
And, yes, dumbfuck, Corn Ethanol has a Positive Energy Balance. Even the most strident of its critics now recognize a 2.3:1 btu balance. And, those are nat gas btus, not petroleum btus.
ReplyDeleteThere is only about 1 (often less) petroleum btu in 20 btus of ethanol.
You're welcome.
ReplyDeleteNow, here's what scares the Oil state Republicans to death.
ReplyDeleteThe corn ethanol plants will, in the fairly near future, have a companion plant processing corn stover, and cobs.
This companion plant will provide all of the process energy for itself, and the corn ethanol plant (thus taking away the energy balance argument, once and for all, even for the dumbass republicans,)
but will be selling electricity by the scads all over the Midwest, severely pissing off the coal state Pubs, AND dems.
On CNBC, they where talking about where American college students ranked internationally on math and science. I missed the actual rankings but based on PISA rankings in December the US was ranked 35th in science (out of 57 countries) and 21st in math. The math was up from 29th place two years ealier. Pretty good improvement but still the ranking was still pretty low imo.
ReplyDeleteAffirmative action + affirmation of feelings = Negative Correlation Coefficient of Ranking
And, as for the hungry poor peepulz: Let me say it again; Poor peepulz don't eat field corn.
ReplyDeletePoor Cows eat field corn, and are, in turn, eaten by Rich Peepulz.
Also, the Co-Product of ethanol is Distillers Dried Grains (DDGS)
You get half of your Feed Value back in DDGS. So, instead of using 4 billion bushels of cattle feed you actually use 2 billion bushels of cattle feed.
Approx 2% of the world's grain output goes into ethanol.
However, in the process of going from four cents/lb to eight cents/lb (how many pounds of corn do you think YOU can eat in a day?) you have given 1.7 Billion malnourished subsistence farmers a potential "cash crop,"
which could very easily lead to "Less" malnourishment, not more.
Well, hell, Deuce, no nation on earth sends as high a percentage of their students to college as the U.S. (at least, as high a percentage of Marginal students.)
ReplyDeleteThat missile defense system wasn't built in China, or India.
No flowers, no card, nothing.

ReplyDeleteBut, in case someone might be curious, the producer will need a price of about $2.25 - $2.50 to make a decent profit with enzymatic cellulosic ethanol. (Without Any Subsidies)
Wholesale ethanol is selling for $2.61 gallon, today.
Ruf, you get upset when we question you on your numbers or on whether cellulosic ethanol is currently ready for prime time. Admittedly, no one here puts in the time you do on this subject. Yet every day there are articles put out that dispute one or more aspects of your numbers or view on this subject.
There is no point in you getting upset when some of us ask to see some evidence, i.e. substantial commercial producion and usage.
You laughed at my definition of short-term as a year or two. What is your definition of short-term?
And given that definition, when do you project we will see cellulosic ethanol commercially available and used in large quantities without (as you noted above) subsidies?
.
.
ReplyDeleteYou snicker and mock us poor bumkins for 'not getting it'; however, you have to admit it's not all that straight forward.
For instance, you state "The ones that work are the "Enzymatic" processes. Inbicon built the first one in Denmark, and it's working like a charm." Heck, I might know something about the enzyme guys but didn't know anything about Inbicon so I looked them up.
Inbicon Commercialization
From what I can see this paper was put out by Inbicon in October, 2010. It purports to show the path to commercialization for their process. There are 15 slides in the presentation. Slide 4 summerizes the requirements they need for commercialization.
The first requirement is a ‘proven technology in place’. They say they have proven this through pilot and demonstration plant volumes completed late last year. The second requirement is a 'demand for end products'. The last is 'feasible projects'. These are covered on slides 12, 13, and 15.
I am going to posts comments on those slides separately because of blogger.
.
.
ReplyDelete[Ref: Inbicon Commercialization Chart Above]
From what I can see, Slide 12 is just a general projection chart showing the projected growth in 2G ethanol between 2009 and 2015. You are probably a lot more familiar with what it is saying.
The only things I noted that were interesting was the the U.S. growth is all projected to be politically "targeted". I assume that refers to the current mandates through 2022.
Also, of note is that Brazil's total usage drops for some reason and that Inbicon is using BP figures for their baseline projections.
.
.
ReplyDelete[Ref: Inbicon Commercialization Chart Above]
The most interesting slide in the Inbicon presentation (for me) was Slide 13 and to a lesser extent Slide 15.
From what I can see from Slide 13 and Slide 15, Inbicon is looking for subsidies, grants, loan guarantees, tax credits, and R&D/demonstration funding for as far as the eye can see. Maybe I'm missing something here.
In addition, looking at Slide 15 and Slide 12 together Inbicon seems to be saying that the projected growth in U.S. ethanol usage is driven by government mandate. That's understandable given the mandate is already in place through 2022.
However, they project a doubling of usage in the EU, that is dependant upon higher incentives being offered. Asia and Brazil also have a question mark next to them.
Slide 15 is on 'feasible projects'. It outlines ways projects become feasible. It lists the following;
Feasibility is possible through:
1.
Cheap biomass (already collected)
2.
Integration with power plant
3.
Integration with anaerobic digester
4.
Local incentives
Many of these get back to the problem of NIMBY that I have mentioned before.
For me there seems to be a lot of questions on the timing for commercial quantities of 2G ethanol. You usually dismiss these concerns as the rantings of a loon.
So my questions are,
1. Am I missing something in Inbicon's 'road to commercialization' presentation?
2. Does the presentation present a viable plan to get to commercialization?
3. Based on your expertise, when can we expect the commercialization of cellulosic ethanol to be implemented in significant quantities, without subsidies and incentives?

Real World Switchgrass yields.
(5 year yields typically average about 1/3 less than the max yield year)
Alabama:
"... the average annual hay yield for Alabama is about 2.5 tons per acre, ..."
bioenergy.ornl.gov/papers/misc/switchgrass-profile.html
IOWA:
"Switchgrass yields observed in the field range from slightly less than. 1 to more
than 4 tons per acre per year of biomass."
www.iowaswitchgrass.com/__docs/.../Costs%20of%20Switchgrass.pdf
@ 96 gallons per ton, we're talking 100 to 400 gal/acre, not 1,000.
Test plots managed by the Univ of Georgia averaged 6 tons per acre,
and required 13 gallons of gas per acre rather than your 1 gallon.

Then we have transportation and storage costs, and energy inputs:
Table 4. Storage.
Building costs $12 per square foot $360,000
Yearly costs:
Land, 2 acres $160
Building: yearly ownership cost at 12% $43,200
Storage cost per ton $16.67
Transportation and Handling
Assumptions
• For these estimates, the switchgrass bales are staged along the edge of the field.
This cost is included in the production budget. A farmer with a typical tractor and
bale fork can perform these duties.
• Another transportation cost is collecting, delivering and unloading the bales into
a storage facility. A semi-trailer holding 20 tons (or 42 bales) is used to haul the
switchgrass. Estimated times are 30 minutes to load the truck and 20 minutes to
unload. The charge for the semi is $70 per hour.
• A typical tractor and bale hauler will not work to stack large square bales 20
feet high. More specialized equipment is needed for this task.
Estimated costs of such a tractor were $20 per hour and $10.78 worth of fuel per
hour. The operator charge is $12 per hour.

EPA
ReplyDeletetests the 'green' value of ethanol
Our paper was not by any means to come down on ethanol," said Hill. "But we need to
be sure that if there are better options out there, that we're taking advantage of
them."
Those options include cellulosic ethanol, which is made from other plant sources
such as crop waste, grasses or wood chips. In most studies it easily passes the
EPA's greenhouse gases test.
But no one's figured out yet how to make money on that fuel.
Energy Return on
ReplyDelete(Energy) Investment (EROI) of Corn Ethanol
Conclusions:
The debate over the EROI of corn ethanol has been concerned mostly with whether it
is a net energy yielder. As such, the dialogue has veered away from many of the
larger implications of EROI analyses. Our results indicate that the EROI of corn
ethanol is statistically inseparable from one energy unit returned per energy unit
invested, and it is likely that much of our ethanol production is acting as an
energy sink, requiring more energy for production than that contained in the ethanol
product. This conclusion was confirmed in our spatial analysis, where the average
EROIRG was 0.06 lower than the average calculated from the literature.
Increasing yields is oft-touted as a way to increase the EROI of corn ethanol, but
our analysis indicates that the gains in EROI are small even when the average yield
from 2005 was tripled. Co-product credits, on the other hand, have a large influence
on the EROI from corn ethanol. There is no consensus within the literature regarding
an appropriate co-product value, and until one emerges (one way or another), we
should err on the side of caution when applying credits to co-products.
Finally, the analysis of ethanol production from biorefineries supports our
conclusion from the spatial analysis: the EROI is too low in too many locations to
make an impact on our gasoline consumption. Our best estimate is that the net energy
provided from ethanol accounts for only 0.8% of the net energy provided by gasoline.
The evidence provided in this research is clear: we do not know the exact EROI of
ethanol, but even if we are remotely close (± 0.2), we are still, in the best case
scenario, gaining an insignificant amount of net energy.
Furthermore, Hall et al. (2009) estimated that only fuels with an EROI greater than
3:1 provide the requisite net energy to provide a fuel source and to maintain the
infrastructure associated with the current U.S. transportation system.
Fuels that have an EROI below 3:1 require subsidies from other energy sources to pay
for all of the infrastructure associated with the transportation system of the US.
The EROI of corn ethanol that we calculated is lower than the 3:1 threshold,
indicating that corn ethanol requires large subsidies from the general fossil fuel
economy, and as a result, drains energy from the US transportation system.
One Molecule could cure our addiction to oil
ReplyDeleteCellulosic ethanol, in theory, is a much better bet. Most of the plant species suitable for producing this kind of ethanol — like switchgrass, a fast- growing
plant found throughout the Great Plains, and farmed poplar trees — aren't food
crops. And according to a joint study by the US Departments of Agriculture and Energy, we can sustainably grow more than 1 billion tons of such biomass on available farmland, using minimal fertilizer. In fact, about two-thirds of what we throw into our landfills today contains cellulose and thus potential fuel. Better still:
Cellulosic ethanol yields roughly 80 percent more energy than is required to grow and convert it.
So a wave of public and private funding, bringing newfound optimism, is pouring into research labs.
Venture capitalists have invested hundreds of millions of dollars in cellulosic-technology startups. BP has announced that it's giving $500 million for an Energy Biosciences Institute run by the University of Illinois and UC Berkeley.
The Department of Energy pledged $385 million to six companies building cellulosic demonstration plants.
In June the DOE added awards for three $125 million bioenergy centers to pursue new research on cellulosic biofuels.
There's just one catch: No one has yet figured out how to generate energy from plant matter at a competitive price.
The result is that no car on the road today uses a drop of cellulosic ethanol.
The step that has perplexed scientists is the one involving enzymes — proteins that come in an almost infinite variety of three-dimensional structures. They are at work everywhere in living cells, usually speeding up the chemical reactions that break down complex molecules. Because they're hard to make from scratch, scientists generally extract them from microorganisms that produce them naturally.
But the trick is producing the enzymes cheaply enough at an industrial scale and speed.

About My Support for Natural Gas
ReplyDeleteThe truth is, every problem associated with drilling for natural gas is solvable. The technology exists to prevent most methane from escaping, for instance. Strong state regulation will help ensure environmentally safe wells. And so on. Somewhat to my surprise, this view was seconded by Abrahm Lustgarten, a reporter for ProPublica who has probably written more stories about the dangers of fracking than anyone. In a comment posted online to my Tuesday column, he wrote that while the environmental issues were real, they “can be readily addressed by the employment of best drilling practices, technological investment, and rigorous regulatory oversight.”
The country has been handed an incredible gift with the Marcellus Shale. With an estimated 500 trillion cubic feet of reserves, it is widely believed to be the second-largest natural gas field ever discovered. Which means that those of you who live near this tremendous resource have two choices. You can play the Not-In-My-Backyard card, employing environmental scare tactics to fight attempts to drill for that gas.
Or you can embrace the idea that America needs the Marcellus Shale, accept the inconvenience that the drilling will bring, but insist that it be done properly. If you choose this latter path, you will be helping to move the country to a fuel that is — yes — cleaner than oil, while diminishing the strategic importance of the Middle East, where American soldiers continue to die.
It’s your call.
If the EPA was "right" doug, why in the whirled would the Republicans be trying to defund it?

ReplyDeleteQ, Everything is political. Exxon, and Shell own Oil Fields, not Corn Fields. They would Never, ever use a drop of ethanol if not forced.
How does this in any way answer the questions I raised above on the Inbicon post?
Everything is political? Of course it is. That's why the US is still paying oil companies subsidies they don't need. That is why the East Coast is fighting the West over government dollars for wind. That is why Bush and Obama pushed on electric, mandated it, and now why Obama is talking about taxing it. It is also the reason we have a mandate on ethanol usage. Don't even get me started on the influence of the 'greens' or local NIMBY concerns.
You proclaim ethanol is the way to go and cellulosic is the wave of the furture. Maybe. But then, you also constantly tell us ethanol is competitive. That it can be so without subsidies. Yet the CEO of the company you mention as an example of it "working like a charm" puts out a paper saying commercialization (if I read it right) is a little iffy and will depend on mandates, subsidies, tax credits, etc., etc.
When some here raise questions about your rosy perspective they are called dumbfucks and morons. You have a simple answer for everything. When rising food prices and resulting riots in the ME and Africa are mentioned, you talk about the corn content in a box of corn flakes instead of any mention of the supply demand effects of commodity shortages. You assume all that fallow land out there is just waiting to be tilled for switchgrass. You have a simple answer for everything like "we'll just build a generating plant next to it" ignoring local zoning and NIMBY issues.
When asked if it is so good, so competitive, cheaper than gas, why aren't we doing more of it commercially, you tell us it is "only" because of a plot by the big oil companies and the GOP.
Sorry, I'm not that credulous. Are some Republicans and big oil against ethanol? Sure. Is that the only problem ethanol has? I don't think so.

Just as Quirk complains about Rufus nipping and tucking at the truth to come up with a simple answer, you have done here:
A careful reading of Quirk's arguments and the articles I posted indicate that cellulosic ethanol is still a work in progress, and specifically awaits the development of industrial scale enzyme production.
Building out a national infrastructure before a commercial solution is found would be madness.

Also ignores the fact that unlike breweries and corn ethanol plants, cellulosic is not a simple operation that can be easily downscaled.
Being that this is the case, transportation and storage of LARGE amounts of feedstock becomes another limiting factor.
(instead of Rufus's small tractor, specialized equipment is used to stack and store, as is noted above.)
