Solar charged electric motorcycle in Apache Junction
GreenFuel Technologies goes down...
We've often wondered what happened to the GreenFuel/APS algae pilot: now we know.
Getting the whole thing to run smoothly [...] was tougher than expected. GreenFuel could grow algae. The problem was controlling it. In 2007, a project to grow algae in an Arizona greenhouse went awry when the algae grew faster than they could be harvested and died off. The company also found its system would cost more than twice its target.
The closed photobioreactor model used by GreenFuel (and others) appears especially challenging in terms of up-front expense.
I recently posted a link to a paper by Jeff Hassania which discusses the sobering economics of algae.
A GreenFuel Technologies timeline is available at BiofuelsDigest.

Visit to XL Renewables

On Monday I had the opportunity to visit the XL Renewables algae production facility in Casa Grande, AZ and was deeply impressed by the progress they are making: among other things, I was able to leave with some sample algae that was a HUGE hit with the 7th grade class I spoke to about biofuels on Tuesday.
I particularly like the trench-based, farm-like model that XL pursues, as their low-cost approach seems like a promising way to address the difficult economic challenges that algae producers face. It was also great to speak with Mike Bellefuille and George McNeely of XL and hear about the hard-won lessons they are learning about growing algae at production scale -- they've had to navigate through a host of practical difficulties and now have invaluable experience (and lots of algae!) to show for it.
It's fantastic to see algae moving beyond just lab experiments and PowerPoint slides. Kudos to XL for meeting the "running code" test!

Desert Sweet Biofuels forum at ASU SkySong
Mark is planning to facilitate additional forums where different companies and organizations can do a "deep dive" on their particular technologies or vision (i.e., not constrained by the 5 minute format we insisted on for the Workshop). Please contact Mark if you'd be interested in presenting at such a forum. We're envisioning a monthly speakers series, picking up in the Fall.

2nd DBI Workshop summary
2nd Desert Biofuels Workshop and DPFs: an update
We just had a fantastic 2nd Desert Biofuels Initiative Workshop at ASU SkySong; about 150 in attendance, and just a great energy and buzz during the 3 hours from 9a to 12p (plus post-workshop pizza lunch: score! Huge shout-out to Dan Rees and AZ Biodiesel for paying the pizza man).
Brad did an unbelievable job in organizing and playing emcee. The format was a series of fast-paced 5 minute "update" presentations, including many who presented last year, and some new faces. A webpage with the slides from today's event is already online.
I limited myself to some (mostly) extemporaneous remarks, and started by asking: "how many of you drove here today using biofuel?" As you might guess, even among this self-selected and highly motivated group, I would (generously) estimate a dozen hands went up.
When I got home I wrote up and expanded on my thoughts, put them into PowerPoint, and they're now also online. Kind of like a mulligan. Cool.
But it was my closing comment that got the most attention of my talk: I mentioned the ongoing issue with diesel particulate filters, which are being used in newer passenger vehicles with diesel engines. After expressing new-found respect, and even empathy, for the engine manufacturers, I noted that anyone who is running biodiesel in these newer engines should be aware that in-cylinder injection of fuel in a post-combustion process can experience problems, like oil dilution, high and/or premature wear, etc.
I summed up with something like: what are we going to do if we finally get widely available biodiesel, and then don't have any new vehicles that are compatible with it?
I've blogged about this issue previously, and I had several people approach me at the break to ask me about it, and later received a phone call of disapprobation from a prominent local biodiesel advocate.
I think I've been about as public an advocate of biodiesel as most people can be, without being a public figure, so I want to clarify that I'm talking about a very specific technical, but real, problem with newer engines and their biodiesel compatibility.

FUEL film extended in Scottsdale

FUEL film follow-up

Dave posted a introduction to the Josh Tickell film "FUEL" which is now showing at Harkins Camelview 5 in Scottsdale. I was invited to this Saturday's 7p show; afterward there was a short Q&A with Greg Piraino of Applied Engineering (who's helping with local promotion of the film), Greg Pitz of Logos Solar, and me. Friday's panel included Mark Edwards of GreenIndependence.org.
Saturday's audience included Dan Rees of AZ Biodiesel, who answered questions about getting biodiesel into local school buses, and James Towner of AZ Sustainability.com and the Arizona Alternative Fuel Alliance.
The film itself was visually compelling and told Josh's personal story around biodiesel, with a liberal sprinkling of political muckraking. Tighter editing would help; toward the end of the film not much new is being said. Dorothy attended as my "guest" and Harkins got his $5.50 for Emily. All three of us were fidgeting in our seats by the 90 minute mark of the nearly 2 hour movie. The soundtrack was fantastic.
Many of the issues are more nuanced than the somewhat histrionic version Tickell presents, and some of the interviewee's proposed solutions would only exacerbate our current problems (new government mandates and subsidies are mentioned more than once as "obvious" solutions).
One of the reasons *why* we are in this pickle: we don't pay, at the pump, the true cost of petroleum (we pay in other ways, though: through higher taxes to pay for foreign entanglements, and Superfund cleanups, for example). These externalities subsidize our petroleum dependence, and prevent alternatives from competing on a level playing field. This is a *hard* problem for which lots of solutions have been proposed.
And it seems, at least to me, that few people want to acknowledge the obvious: we benefit greatly from cheap energy, in the form of, well, everything! Food, clothes, housing, ... Whatever the solution is it better be consistent with first principles. Is massive social engineering really required? To quote David Boaz: "A socialist system - or an interventionist state, which is just partial socialism - requires uniform solutions to problems rather than the myriad variety of solutions available through the market process." [1]
Here's a simple question: Are we willing to pay for what we use?
Despite its faults the movie achieves its main purpose: to inform and, more importantly, to motivate those rapidly diminishing number of persons who are unaware that we have serious and immediate issues with our continuing dependence on petroleum. It'll also be interesting to see if Tickell can generate enough buzz, and money, to fund a follow-up: something that provides a "deep-dive" into some of the proposed alternatives to oil.
After all, folks (especially those for whom this is all new) want to know: what do I *do*? Suggesting CFLs is good as far as it goes, but kind of misses the point. Using his own logic, if the situation is really as dire as Tickell suggests, then we *really* need to focus on the big wins.
But enough nit-picking: FUEL is *definitely* worth checking out.

The FUEL Film
Over the last few years, Josh parted ways with the homebrew community (accused of "selling out" and abandoning amateur scientists and engineers) to reach a broader audience, primarily through presentations and keynote addresses to farmers, policymakers, and investors. For years, he's been working on shorts and a feature-length documentary, which won accolades at independent film festivals worldwide.
Now, buoyed by the support of Hollywood icons like Peter Fonda, the film is building national momentum. In fact, it starts tomorrow in Scottsdale. I plan to attend the Saturday 7pm show, where Josh will be leading Q&A (according to his website: http://thefuelfilm.com/).

2nd Annual Desert Biofuels Workshop - April 24, 2009
Our first Desert Biofuels Workshop, held in March of 2008, was an exciting event; attendee feedback included comments such as:
- "...a watershed for AZ biodiesel..."
- " ...never been at a conference with such broad representation, from corporate, to government, education, NGOs and home brewers..."
- "...showed just how important this topic is..."
- "...tremendously valuable..."
Details about last year's event can be found here (the "agenda" .pdf file includes links to the slides presented by each speaker).
For our second annual Desert Biofuels Workshop we hope to build on last year's success. Our primary goals for the Workshop are to (1) enable the diverse members of the Arizona biofuels community to connect with each other, and (2) explore how the $50 Billion in energy programs in the stimulus bill can advance biofuels in Arizona.
Confirmed presenters include (in alphabetical order):
- John Andrews, Principal, Biofeedstocks Global
- Andrew Ayers, CEO, Algae Biosciences
- Ben Cloud, President & COO, XL Renewables
- Jeff Collier, CEO, Energy Derived

Amereco B99 at Western States Petroleum
According to the folks I spoke to, WSP is now selling only Amereco B99 (which is made from WVO) at the B99 pump at 16th Ave and Grant, and the Iowa "Soy diesel" is only available to bulk customers.
Light duty B99 pricing on 1/28/09 was $2.19/gal.
Way to go Bill!
Meeting the Phoenix Biodiesel Task Force
After I received the email meeting invitation last week, we quickly enlisted the aid of several DBI "advisers" to get input on what to present and how to present it. Hans Huth in particular gave invaluable feedback on our slides (which we will post on our website). (Sidenote): Hans' manual is exactly the type of thorough, well-organized information that homebrewers can use to be safe and effective, and it gives real weight to the assersition that homemade biodiesel can be done responsibly.
Going into the meeting we didn't have any idea of what had already been discussed within the City bureaucracy, or how much impact we would have with our presentation. But it was great to be invited to participate.
As the various department reps assembled (Fire, Planning, Development Services, ...) we had a chance to review the minutes from the initial Biodiesel Task Force meeting, held Dec 12, 2008. At that meeting, according to the minutes, it was decided that "Planning will start drafting changes to their ordinance to prohibit bio-diesel manufacturing in residential zoning." Ugh! It appeared that we would be facing an uphill, and perhaps futile, slog.
Brad gave a short intro about DBI and then segued into my presentation about "homebrew". My purpose was: a) to accurately describe the basics of making biodiesel at home, b) to describe the advantages and challenges of homemade biodiesel, and c) to emphasize (as previously discussed here) that although it may not be reasonable to make large quantities of biodiesel at home (with "large" yet to be defined), it was certainly reasonable to allow some quantity of biodiesel to be made at home, and Phoenix residents should be at liberty to pursue their "homebrew" activities as long as they do not negatively impact their neighbors. We noted that the Town of Gilbert has already taken a "pro-homebrewer" stance which we find very encouraging, and we expressed hope that the City of Phoenix will follow their lead.
Whether or not we achieved these goals, we did have ample opportunity to answer the numerous questions that came up. And, in closing, we emphasized the need to continue dialog on this issue.
DBI will be hosting a "homebrewer safety" workshop at ASU SkySong where we hope to assemble homebrewers, home biodiesel processor manufacturers, biodiesel cooperatives, and various government stakeholders, the purpose being more constructive discussion on this topic.

(Mis)reporting the problems with biodiesel
Some Cold Truth About Biodiesel In Minnesota
School buses that left kids stranded in the cold, buses running a biodiesel blend per the Minnesota B2 mandate, were reportedly disabled by the biodiesel turning "gel-like".
The truth, it appears, is that the petroleum gunked up the fuel system, according to the National Biodiesel Board.
Hmmm....
Coffee diesel: update

Ken Costello has done an initial oil extraction from the coffee grounds we procured from MonaLou Callery's Cup o' Karma. It turns out that the coffee grounds only contain about 10% oil, and the amount of hexane lost to evaporation exceeds the amount of oil extracted (at least in the small amounts used for his testing) by a factor of 4.5!
To get 15ml of coffee oil Ken lost 70ml of hexane during the extraction process (he recovered 230ml). Since hexane costs about $16 a gallon, plus shipping and hazmat fees, we probably aren't looking at a new feedstock for biodiesel! A lot of the hexane lost was residue in the coffee grounds that evaporated out when the grounds were dried, after extracting the oil. Residual hexane in the coffee oil also reduced the final amount of coffee oil.
Ken will be trying additional extractions to a) see if he can reduce the amount of hexane lost in processing, and b) scale-up the process to get us to a gallon of coffee oil to turn into biodiesel.
You can check out Ken's full write up of his experiment on his Chemistry Land website.

Coffee diesel
Spent Coffee Grounds as a Versatile Source of Green Energy
Narasimharao Kondamudi, Susanta K. Mohapatra, Mano Misra
Journal of Agricultural and Food Chemistry 2008 56 (24), 11757-11760
Paraphrasing, he said: "Wouldn't it be cool if we could get used coffee grounds from a local coffee shop, extract the residual oil, turn it into biodiesel, and document the process via pictures, video and blog(s), from start to finish?"
Well, why not?
Ken Costello is a friend of Desert Biofuels and was intrigued by the idea. He agreed to do some small test batches to determine how much oil was present in the coffee grounds. MonaLou Callery, who operates Cup o' Karma in Mesa, agreed to collect coffee grounds for the project.

So yesterday I went down to Mesa and picked up two 5 gallon pails of coffee grounds and delivered them to Ken this morning. He'll be spending at least part of this afternoon trying to find out the percentage of residual oil in the grounds, and then a reasonably efficient way to scale up the extraction process so that we can get about a gallon of oil to turn in to biodiesel.

We'll post a full report, with pictures and maybe video, sometime soon.

Diesel Particulate Filters
There are a couple problems with this system:
- extra fuel is used to burn the particulates, which reduces overal MPG.
- extra CO2 emissions are released when burning up the particulates.
- Biodiesel, which vaporizes a higher temperature than petroleum diesel, doesn't function the same way in the system, and fuel ends up in the engine crankcase rather than clearing the DPF. [1]
http://biodiesel.infopop.cc/eve/forums/a/tpc/f/419605551/m/2721003282
[1] It depends on how the system is designed, of course. The problem is caused by using the fuel injectors in the cylinder to place additional fuel into the exhaust gases. Since biodiesel doesn't vaporize per the system design, some of it stays in the cylinder and leaks past the piston rings into the crankcase. If the additional fuel is squirted into the exhaust pipe, and not the cylinder, then you bypass the problem of fuel getting into the crankcase. But that is more complex and maintenance intensive (additional dedicated fuel injectors).

Visit to potential demonstration algae biofuels site
We made a trip today to the site for our proposed algae biofuels demonstration plant. The land, near 19th Ave. and Lower Buckeye Road, just southeast of downtown Phoenix, is really perfect in many respects: great water and power infrastructure, close to downtown but zoned industrial, flat and sunny. The quality of the land coupled with some progress we're making on the grant funding side has me in a state of optimism and excitement with the project at the moment -- which, of course means that the next iteration of frustration and despair is just around the corner, but we'll take what we can get. :-)

Phoenix reportedly creates biodiesel task force
Joe McElvaney, a Phoenix fire protection engineer, said the city requires a permit to handle the flammable and combustible materials used in biodiesel. But many home brewers ignore zoning regulations and waste-disposal requirements.

Almost there!
Dan Rees and his son Richie gave us a tour of their new facility, and we spent a couple hours discussing the numerous obstacles they've had to overcome, and some they still face, to get their business off the ground.
Their test batches are dialed, and except for a few new (and rather esoteric) testing requirements, they will be ready to begin selling to the public very soon.
AZ Biodiesel is really the best example we have of the community-based commercial model of local biofuels that DBI is championing: local restaurants giving their grease to a local company, which in turn makes ASTM-spec fuel to be sold locally. Environmentally and economically: what a huge win for our community.

Mark Edwards - Green Independence
Mark Edwards is a close friend of and a key strategic advisor to our Desert Biofuels Initiative effort. We're very pleased to be partnering with Mark to help him advance some components of his global "Green Independence" vision.Mark is a professor in the Morrison School of Management and Agribusiness at ASU and the author of Biowar I -- which focuses on problems associated with corn ethanol, among other issues -- and Green Algae Strategy, which lays out a compelling vision for how algae can solve critical global fuel and food problems. We've found Mark's vision to be inspiring, and we're striving to implement aspects of his vision in an algae biofuels demonstration plant project we're exploring with Mark and a number of other team members.
Mark has generously agreed to allow us to post some documents he's authored that capture some of his thinking on Green Independence and related topics (all in .pdf):
- Green Algae Strategy Summary and FAQs
- Mark's Speaker Brief from a recent talk (addresses algae and summarizes Biowar I)
- Green Independence (version focuses on U.S. transportation fuel issues)
- Biowar I powerpoint slides
Mark has also made available reviewer copies of his full Green Algae Strategy manuscript that we can provide electronically upon request (to brad-at-desertbiofuels-dot-org).

DBI policy projects for Fall '08
Our relationship with ASU's Technology Ventures Services Group (formerly Technology Ventures Clinic) continues to be exciting and productive for DBI. This Fall we have three extremely talented students joining us, to work on two projects. The projects are:
1. A market analysis of biofuels feedstocks in Arizona, focusing on (a) waste vegetable oil, (b) region-suitable agricultural feedstocks, and (c) algae. The goal of the project is to gather facts about precisely what is happening in AZ in connection with these feedstocks (e.g. how much WVO is there? where is it currently going? what agricultural feedstocks looks promising for our region? etc.) . Our hope is that this sort of data will enable regional biofuel producers to make solid investment decisions and will help policymakers who are interested in advancing the regional production of biofuels. This project is an expansion and continuation of the project that we launched this past summer.
2. An analysis of state-level legislative initiatives aimed at promoting biofuels that have been enacted in other states. The goal of this project to accumulate data that may be helpful to Arizona policymakers interested in advancing the production of sustainable biofuels locally.
The students are:
- Pete Arambula, a third year J.D. student with an M.A. in Physiological/Experimental Psychology and professional interests in biotech, health science, civil rights and sustainability.
- Sarah Howe, a junior in the undergraduate chemical engineering program at ASU's Barrett Honors College. Sarah has biodiesel homebrewing experience and a deep interest in environmental engineering.
- Carrie Thomson-Jones, a J.D. student and former entrepreneur and business owner. She brings deep business experience and savvy to our projects, plus has the additional incentive of hoping for success of our mission so that she can regularly run her VW TDI on biodiesel.
We're grateful to Eric Menkhus and the entire team at the Technology Ventures Services Group for all of their support.

US Fire Administration on Homemade Biodiesel
"The overall process [of making biodiesel] is legal and relatively safe when properly performed."It goes on to list some of the potential hazards, and notes:
"If the [home] processors are not careful, they can poison or burn themselves, and modifications to pressure vessels by inexperienced people can result in possible explosions."Thanks to Hans Huth for the referral.

Unfortunate / Opportunity
While DBI remains favorably disposed toward the idea of individuals producing their own fuel [1], there are very real safety and legal obligations in making biodiesel. One of my realizations after making biodiesel for a while was that it just wasn't reasonable to expect that a family in a residential area could make themselves fuel self-sufficient. [2]
While some would assert that no amount of biodiesel can be safely made at home, I still believe the issue to be resolved is how much is too much? Some folks are going to do what they will, regardless of what anyone says, but for those who are trying to be good neighbors while they pursue their homebrew activities a couple things seem obvious:
1) Making a "Dr. Pepper" batch is a perfectly reasonable example of homebrew biodiesel, even in a residential setting.
2) Making hundreds of gallons per week for a "cul-de-sac biodiesel coop" is not. [3]
The question is: where on that continuum -- between a liter test batch and hundreds of gallons for friends and neighbors -- can a reasonable person say "this is (or should be) permitted" in a residentially zoned area. And I mean this activity is permitted in the sense of "non-interference" from the authorities, not sanctioned or licensed by them. The City of Gilbert has a forward-thinking approach on this issue, based on work done by the Arizona Emergency Response Commission.
Anyone who is currently contemplating "homebrewing" biodiesel would be well-advised to do some extensive investigation into the safety and legality of making fuel at their residence. A great starting place is Hans Huth's excellent "Biodiesel 101", which is an updated (and improved) version of a widely used homebrewer's guidebook, and has the additional benefit of Arizona-specific legal/tax information.
What may be an even better alternative is to join a biofuels cooperative, such as Dynamite Biofuels Co-op. This leverages the experience of persons who have been doing this for years, and neatly side-steps the idea of residential fuel production altogether.
[1] Brad put his thoughts into a dbi-workshop forum post which I think neatly captures our thinking:
"Re homebrewing, while I'm not a homebrewer myself, I personally remain favorably disposed to homebrewing, subject to a few serious caveats. I admire the do-it-yourself, self-sufficient culture that homebrewing embodies -- it seems somehow quintessentially American. I like too that homebrewing is a manifestation of an extremely decentralized model of fuel production -- I think the trend towards decentralization in fuel production is good for everyone except a few petrol fuel stakeholders. And homebrewers meet our "running code" test: they have been getting sustainable biodiesel into fuel tanks and on the road for years, with all of the attendant air quality and other benefits. The grassroots energy of homebrewers has significantly helped the adoption of biofuels. Plus there's an element of liberty: people should be free to pursue their homebrewing interests (and put non-ASTM tested fuel into their own personal vehicles) unless and until they create unwarranted risk for others."
[2] I use about 15-20 gallons of biodiesel a week. Add an additional vehicle (or three, in my case, if I count my two sons, who both wanted in on this deal :-) and let's say for round numbers 40 gals of biodiesel a week. That means processing 45-50 gals of oil per week, which uses over 10 gals of methanol and approx. 3 lbs. of catalyst. I would also have to dispose of at least 15 gals of glycerol/soap and, if water washing, more than 80 gals of high BOD wash water a week. Keeping enough methanol around to avoid running every week to get it, and enough catalyst for same, means we've probably moved beyond what could be considered reasonable in my home. However, doing a 15 gal batch per week, as I did for several months, meant keeping only 10 gals of methanol at the house, good for about 3 batches. By avoiding water-wash entirely using Graham Laming's process, and composting the glycerol, I found it quite reasonable to fuel my personal vehicle from 50-100% with homemade biodiesel.
[3] I want to emphasize I am talking about typical, densely packed residential neighborhoods. At the closest point the gap between the roofs of my house and my neighbor's is about 15' (I just measured it). And I have only the garage as a work area. There are plenty of residential areas in Phoenix where there is enough room to safely make hundreds of gallons of biodiesel a week in an out-building away from anyone else's property. A lot of people would disagree with that statement, though :-)

Torrey Kolesar joining DBI
Another piece of exciting news for DBI (in addition to the release of our regulatory white paper) is that Torrey Kolesar will be joining us as an intern this summer. Torrey is a junior in ASU's Barrett Honors College, where he is studying chemical engineering and finance. Torrey was part of a groundbreaking effort in Ghana, Africa to develop a biofuel infrastructure based on Jatropha feedstocks, and is co-author of a biofuels wiki hosted by ASU. We're thrilled to have Torrey on board.Torrey will be leading a project to assess the current state of biofuels feedstocks in Arizona. The goal of the project is to analyze WVO, agricultural and algae feedstocks, assessing issues such as current market structure, supply/demand, costs, and feasibility. Our plan is to publish the results of Torrey's research as a white paper, and to host a meeting at ASU SkySong in the early fall where Torrey can present and discuss his results with interested parties.
We're also hoping that Torrey will contribute to this blog, and envision that he'll participate in some of the other projects we have underway.
Torrey can be contacted by email at torrey@desertbiofuels.org.
AZ Biodiesel Regulatory Environment white paper
Deep thanks and kudos to author Sam West, who did an amazing job pulling the paper together.
Thanks as well to AZ Biodiesel, whose generous support of the ASU Technology Ventures Clinic helped make the paper possible.
We expect that the white paper will be a living document that will be revised regularly. The information in the document is not comprehensive or complete, but in the spirit of running code our hope is that it can serve as a starting point for deeper discussions among the AZ biofuels community.

Hunter's new ride
Hunter turns 18 on Tuesday and wants to go to NAU in the fall. Last year I promised him the same deal I gave Nelson when Nels got my old Toyota T100 as a graduation present. At the time I booked out the T100 to get an idea of how much this promise was going to cost.
As we spent the last month or two looking for vehicles, I noticed that all the trucks and SUVs Hunter suggested were about twice the budget I allowed. Hmmm. I kept looking anyway. Last weekend I found a truck online that looked perfect: original owner, less than 100K miles, all maintenance records, etc. It was also within "the budget". So I called and we went to look last Sunday.
Although not perfect by any means -- it was repainted marginally well, the dash is horribly cracked, the stereo is convinced that a (phantom) tape is inserted at all times, the door locks are broken -- it started immediately, ran great, and sounded bitchin'. So I put a deposit down and we picked it up last Tuesday.
What does this have to do with DBI?
Well, everyone who sees it immediately notices that I bought Hunter a BIG truck. Yep. And I'm concerned about the environmental impact of driving, so I run biodiesel. Yep. And this 4x4 pig is thirteen years old, runs gas, and gets (optimistically and according to the EPA) 10 mpg city, 14 highway. Yep.
See, he has to fill it up. He got a truck, not a gas card. And with gas approaching $4.00/gal, and a 35 gallon tank, it will cost nearly $140.00 to fill the damn thing. How much driving is an 18 year old going to do when it takes 14 hours of work to fill his truck? Once! Sure, we need vehicles on the road that get better mileage. But more importantly, wherever feasible, we need to drive less. And a NAU freshman doesn't need to drive much at all. So Hunter got the truck he "needed", the one I promised, and now it's his problem. Maybe he'll even start reading the blog :-)

Another month of record fuel prices
According to the Energy Information Administration:
Based on projections of weak economic growth and record high crude oil and product prices, consumption is projected to decline by 190,000 bbl/d in 2008 [...] After accounting for projected increases in ethanol use, U.S. petroleum consumption is projected to fall by 330,000 bbl/d.So if demand is falling, why are prices rising dramatically?
World oil consumption is projected to grow by 1.2 million bbl/d in 2008. Almost all of the growth in 2008 is expected to come from the non-Organization for Economic Cooperation and Development (OECD) countries, led by China, Middle East oil producing countries, and Russia, as well as Brazil and India [...]more than offsetting any decline in demand in the US.
Bummer for us. Of course, it's also great for us. Fuel prices are starting to more directly affect individual driving decisions, consumer vehicle preferences, and therefore auto manufacturer's vehicle production. Business Week reports:
Ford Motor (F) is cutting its production of its one-time cash cows, pickups and SUVs, to instead increase production of smaller and more fuel-efficient cars.And the New York Times reports:
With technical and environmental hurdles overcome — and facing tougher mileage standards that call for a 35 m.p.g. average by 2020 — automakers are rushing in with clean-diesel cars.Nice.

The Right Biofuels
Articles like this are not just nice to see, but necessary for public awareness, if we are to save the term "biofuels" from being misused to the point it must be abandoned.
Measuring Petroleum MPG
Another angle on this is something I've been thinking about: Petroleum MPG, or PMPG (yes, I made that up! "That just happened!"). Since environmentally it is a heck of a lot better to be running biodiesel from WVO than gasoline from petroleum, for a number of reasons explained elsewhere, I was interested in what my effective MPG was for the truck if I measure based on the amount of petroleum diesel I use.
Since the beginning of the year, when my truck had an oil change (Jan 8), I've driven, as of this morning, 6883 miles. If I counted correctly, that's 107 days, a little over 64 miles a day. Looking at my fuel receipts, and using $3.50/gal as a rough number for that period, I've purchased 86.9 gallons of petroleum diesel. The rest has been either B99 from Western States Petroleum [1], B100 from Dynamite Biofuels Co-op, or my own individually produced biodiesel.
My PMPG is 79.2 miles per gallon.
If I factor in the methanol needed to produce the biodiesel [2] used to increase my PMPG so dramatically, that is another 44.3 gallons of "fossil fuel" products (most methanol is produced from natural gas). That brings my "petroleum" fuel total up to 131.2 gallons for the period.
My PMPG is 52.5 miles per gallon.
Something interesting to think about.
[1] WSP's B99 is not WVO-based, but soy biodiesel from Iowa. I'm giving it a pass here for simplicity. It's still better than petrol diesel!
[2] 20% of the volume of oil for the reaction, but we'll factor in methanol recovery since we are environmentally and economically sensitive :-) , so let's call it 15%.

AZ policymakers "get" biofuels
While we haven't had the opportunity to meet with him personally, another Arizona policymaker who is playing a leadership role in connection with biofuels is federal Representative John Shadegg. As described in this article, on April 4th Shadegg proposed legislation to close the shameful "splash and dash" loophole that has enable foreign biodiesel producers to transship biodiesel through a U.S. port, blend it with 1% petrol diesel, collect a $1 per gallon blenders credit (funded by U.S. taxpayers), and then ship the fuel onward to Europe (or elsewhere) for sale. Kudos to Shadegg for leading on this issue.
[The one potential counterexample we've encountered in connection with local policymakers "getting it" (or not) is AZ Biodiesel's current struggle with the City of Chandler. As described here, AZ Biodiesel is caught up in dispute over zoning and planning issues which threatens to shut them down. Our hope is that cooler heads will prevail and city leaders will figure out a path to resolution that enables this critical local resource to stay online while issues are being addressed.]
DBI Inc., con't
For anyone who wants more info about how we envision DBI evolving, we have a draft 1-pager posted here (.pdf) that might be useful. As noted in the 1-pager, Eric and I see our roles currently as roughly "technical director" (Eric) and "policy director" (Brad), with responsibilities split equally and considerable overlap in what we cover. Also, Sam has been working with us in a role that I think of as "policy analyst." We're all volunteer at the moment, but we're working with some grant writers (whose services have been generously lent to us by ASU Law's Center for the Study of Law, Science and Technology), and if we can raise some money we'll hire in an executive director-type position.
As described better in the 1-pager, we envision our activities falling roughly into three categories: policy, operational and education. On the policy side, our goal is to create a virtual "think tank" focused on biofuels policy issues, working closely with various partners at ASU. Operationally, we're excited about some ideas under discussion about a program to incentivize restaurants throughout the Sonoran Desert region to keep their WVO here for use as feedstock for biodiesel, and about the possibility of creating a pilot biofuel plant that could help local commercial producers bridge new technologies from academic research labs into actual production. On the education front, we plan to continue extensive stakeholder outreach, more blogging and info-gathering, and will plan a second local biofuels summit.
Ultimately we hope to help play a "glue" role connecting the many various stakeholders -- entrepreneurs, policymakers, regulators, researchers, the grassroots community -- who will need to work together in order for "local biofuels" to thrive in Arizona. Our intent is to complement the efforts of other stakeholders, and to try to identify and solve problems that aren't being addressed by others.
