About Me

Robert, I enjoyed your articles and analysis. I am a bit of a novice to this area and a financial type not an engineer. I have a question though. I understand the costs associated with algal conversion to biodiesel are not cost effective, but is there analysis of C02 capture and algae production at coal facilities to utilize cofiring? I’m looking at an opportunity where that would appear to make sense, but wondered if there was any cost analysis out there on production/solar drying to provide a cost/ton of algae feedstock. Thanks for any assistance you might be able to provide.

Hi Richard,

That was in fact the business model of GreenFuels. They were using CO2 from coal-fired power plants to feed the algae. I have heard bits and pieces on the technical problems they had with this approach, but they ultimately went bankrupt.

I think the problem is that algae to fuel is such a sexy concept, people are really too quick to skim over the technical challenges that people have had in the past. However, I think if it is going to work, it will have to be an integrated approach in which the fuel does bear the costs of capital and producing the algae. If the fuel is only a byproduct of another process, then there may be a way to make that work.

Thank you so much for the lucid explanations of the short term and the long term reasons for gas prices. I’m doing a unit on cause and effect and your material cuts through the fog and truly educates.

Mr. Rapier
I enjoyed reading your Guest Column in the Atlanta Journal concerning myths about oil prices in the US. I feel there is an omission that merits consideration, as to whether the President can control oil prices, and that relates to currency.
Whether you blame tax policiy, our two costly and unfunded wars, entitlement spending, our level of borrowing affects the value of our currency, and the cost of oil. Even if oil is priced in dollars, the price of a barrel will reflect the value of a dollar.

Hi Dr. Halpern,

There are in fact many more than 5 myths around gas prices, so there was much I couldn’t cover. Also remember that it is about 5 myths, not necessarily what causes gas prices to rise. I agree that there are impacts from currency fluctuations, but it is also true that oil has risen sharply even if we price it in Euros or Pounds.

Cheers, RR

Mr. Rapier,

As a fairly young person involved in politics and policy, desperately searching for honest analysis amongst a sea of partisan hackery, I was honestly elated to find your blog today. From first read and some cursory examination, you do a phenomenal job of laying out the inconsistencies, spin, and plain misdirection of much of the discussion on energy, and explain the current situation in a way that is more refreshing than I could tell you. Thank you sir, and I look forward to reading more from you in the future. Also, if you have any recommendations for other people who write from your same approach, I would love to hear about them.

Best, Austin

Hi Austin,

Thanks for your comments. I would say that Geoffrey Styles is the person whose essays are most like my own approach: Energy Outlook.

Cheers, RR

Austin, do you have any figures on the energy costs to produce animal fat biofuels per gallon v. the cost to produce fossil fuels and ethanol?

Hello Robert,

I am an avid reader of your blog. In your recent post, you requested feedback from your readers… my request to you would be expanded coverage of the economics of GTL. I keep on hearing on the vast NG reserves the US has, yet it appears nobody speaks about converting those inputs into gasoline. Why?

Congrats on your good work and your courage in tackling difficult and politically sensitive issues.

Good article on Kior. Just saw in german press another star of BTL crash and burn – Choren which you would know well. They had so much but could apaarantly not get the scaling to commercial scale large plant right. The big challenge for all is whether they should be technology suppliers or plant developers and KIOr seems to have fallen into the same trap

Robert, I loved “five misconceptions.” You might find my little film “after the peak” of interest. There is a trailer on the website. If it does interest you, I’m happy to send you a DVD (this is not a sales pitch – I’ll send it to you free if you like the idea of the film). cheers, Jim

Robert,
Have you done any critical review on Alphakat technology developed and marketed by alphakat.de They have a few demonstration plants. I am kind of exploring to try this technology, becasuse getting synthetic diesel from biomass has advantages like distribution and using the product as automobile fuel with out needing to alter the engine of the diesel vehicle.
Thanks / sarita

I have written some about it; more about a person trying to bring this technology to the U.S. than about the technology itself. But this person has been associated with fraudulent claims in the past — never a good sign.

I would like to talk to you about doing a presentation. Please email me

Robert,

I read this article with great interest. If I do not argue with the way it is put in numbers and content I nevertheless shall say this is about antiquated technologies. People that understand about productivity and capital cost do not bother with this. Ponds are inefficient systems, huge consumers of natural and industrial resources and for a commercial bio-fuels avenues have no future.  PBRs as represented by this article are also totally ineffective and capital intensive; so have no future too. This is a fact.  As to Pyrolysis, the carbon foot print is in the way and will be a deal breaker. Because at the end the highest Energy returned to Energy Invested ratio is the goal. 

However, not everything is bad in these existing technologies, if you re-arrange the bio-engineering and you create a new growth system using the best of each existing system and adding some creative features,  you have a complete different picture. Like the coming of the railroad in the industrial revolution. The steam piston engine did not stayt but the electrical engine did it. The railroad still exist, but it has a new and efficient look now with the same tracks.  The algae biofuel will exist, it won’t be with ponds and/or PBRs but something of the both and more. Because photosynthesis will be the same ,just  more intensify and performante.

Robert,

I see your point about Obama  and how he had nothing to do with the rising gas prices . But THAT is the problem.  He hasn’t done anything about it.  The fact that he talks about American jobs and American products is baloney. What about American oil ? Where is it ? Well it’s dead  that’s right buried in the ground.  We are to dependent on foreign oil.  So your right he hasn’t done anything . Or should I say anything about it. 

As always, the formula is “quantity x net energy = total energy”

1.6 trillion barrels of oil is a meaningless number without net energy. We have no idea how much total usable energy is there.
