$600 is the level where butanol becomes

economic as a biofuel


Global driver is need for low cost / low carbon products

Competitive advantage driven by lowest cost of production

Market OpportunityButanol Today:

Chemicals

• Derived from multiple feedstocks

• Superior properties to alternate biofuels

• $50bn p.a. worldwide biofuel market growing 7.5% p.a.

• Regulations requiring biofuel blends guarantees the market (e.g. EU / US)

• Derived from petroleum

• Used for paints, coatings, resins, polymers, and solvents

• $4.3bn p.a. worldwide chemical market, growing at 4% p.a.

• Bio-butanol is a direct substitute

Butanol tomorrow: Biofuels

Butanol: A Superior Biofuel

• Butanol is superior to ethanol:

– Higher energy density and lower vapour pressure

– Better compatibility with existing fuel distribution and vehicle engines

• Also superior to biodiesel

– Cold weather properties and sustainable feedstocks

• Simple market entry through blending in gasoline or diesel
