One of the applications of veg biodiesel was to address the available
issue of diesel in rural areas where there is no grid and generators
are used (also for charging batteries). An idea connected to Jatropha
seeds is that farmers (who charge their battteries to run light and
their TVs) can pay in the form of oil seeds for charging their
batteries.

At Sdao, a farmer is charged 5 Baht to charge a battery (a need to do
it about once a week). It takes e.g. about 1 hr to harvest 3 kg of
Jatropha seeds manually from a Jatropha plantation. 4 - 5 kg jatropha
seeds are needed to extract 1 liter of oil. A day's wage is around
100-150 Baht per day.

Q: Is the economics of such a system viable ?

Jacky one of the benefits to the modern hybrid and fuel cell cars proposed is that when you are not driving them they can power your house for you.

Are you saying that rural farmers should buy a modern hybrid and fuel
cell car so that when they are not driving it, it will light up the
bulb in their single room "house" and their TV ?

I have observed that some subscribers who were originally here for the
Chinese Tallow Tree discussion are starting to signoff from this
G-GROUP.
e.g. Reg Preston (CO/KH)
Kangmin Li (CN)

Kindly avoid the non-CTT discussions in this G-GROUP.

Jacky, I am not saying I recommend it but alternative energy advocates state that a battery operated automobile with an on board engine for generating supplemental power, especially a fuel cell engine, can power the owner's home when parked in the driveway.
 
I suppose that this assumes a cheap source of fuel, such as hydrogen, for the fuel cell.

Hanns-Andre: Biobutanol is butanol - C4H9OH - made from biological
sources. The route being commercialized in the next two years by BP and
DuPont with British Sugar is an advanced version of the classic ABE
route, a bacterial fermentation of sugar to make a mixture of Acetone,
Butanol and Ethanol. This has been improved to yield mostly butanol. ABE
was the main route to make butanol, used mainly now as a solvent and
chemical reactant, until it was displaced by petrochemical routes.

Butanol is a much better gasoline-range oxygenate fuel component, or
even a neat fuel, than ethanol for both technical and practical reasons
- it has high octane, lower vapor pressure, almost as high energy
density as gasoline, low water solubility, so it can be handled in
refineries, pipelines, tankage, and vehicles with no special provisions
(unlike ethanol). The downside is toxicity greater than ethanol, and a
tendency to smell like spoiled milk if a spill degrades - not a bad
trade-off, I think. There are also routes of dehydrating ethanol and
catalytic synthesis from bio-syngas. There is potential to leverage the
intellectual and physical capital already in place for ethanol and BTL
(biomass to liquids - gasification plus FT synthesis) to make
biobutanol.

Nexant is launching a multiclient study entitled "Biobutanol: The Next
Big Biofuel", which I am managing. Our clients are clamoring for such a
study. I will forward the link to the prospectus next week.

Neal: Where did you get the idea that hydrogen is, or will ever be a “cheap source of fuel”?

 

First, hydrogen (H2) is not a source of anything - it doesn’t exist on this planet unless we make it.

 

It is a chemical intermediate, high-tech working chemical, chemical reactant in refineries and natural oil hydrogenation, and aerospace propellant, and a plaything for those who don’t want to get serious about vehicle energy conservation, like George Bush.  No one has yet demonstrated it to be practical or cheap as a vehicle fuel.

 

The pie in the sky is that we will make it from solar electricity by hydrolysis – this is currently an inefficient process, and may always be, excluding some “deus ex machina”. If we can ever get cheap solar power, why not just use the power? – we already have an infrastructure to get that around – it is called the grid. Right now, if we want hydrogen, we have to make it from fossil fuel – we don’t how to sequester the CO2 from those processes, and we may never.

Poor choice of words on my part.  However we can produce it using the trimmings from CTT and some animal manure rich in ammonia, such as poultry litter, in our gasifier.
 
By harvesting the CTT across the southern USA or elsewhere, we will have the tree trimmings, shell of the nut, meal, oil and tallow. Not a bad energy system developing there.  Maybe those African plantations should consider CTT instead of jatropha.
