2-butanol

Basics

It can be used as a direct Gasoline Substitute in unmodified internal combustion engines
Butanol is far less corrosive than ethanol and can be shipped and distributed through existing pipelines and filling stations
It is an effective Hydrogen Carrier in a Hydrogen Economy ; Reformed butanol has four more hydrogen atoms than Ethanol, resulting in a higher energy density
Butanol is an industrial commodity, with a 370 million gallons per year market with a selling price of $3.75 per gallon.
It can be, but does not have to be, blended (10 to 100 percent) with any fossil fuel.
Butanol can be transported through existing pipelines for distribution.
It can be blended with petrodiesel and with vegetable oils (where it also reduces the gel temperature point and the viscosity) to produce biodiesel. ?
It is a very versatile fuel and fuel extender in both gasoline and diesel engines. Octane?

Typically done via Clostridium acetobutylicum
- Any genetically modified algae/e. coli/yeast etc?
This can be done with a starch or sugar based feedstock
It can also be done with syngas (See Syngas Fermentation )
