• Solix’s cost trajectory shows that fuel production f l b t titi ith from algae can be cost-competitive with petroleum – but requires full value extraction f th d ti d tfrom the production co-products

• Solix has now begun operation of the world’s largest closed photobioreactor for biofuel production.

Fuel Properties - GeneralFuel Properties - General

• Algal oil is unique in that it tends to contain a significant quantity (~5-20% by volume) of long highly unsaturated oils, which are rarely observed in more traditional biodiesel feedstocks, such as soy and rapeseed (canola) oil.

• The two most common types of long and highly unsaturated oils found in algae oil tested to date are eicosapentaeonic acid (EPA) and docosahexaenoic acid (DHA).

ConclusionsConclusions

• Economical biofuel production appears Economical biofuel production appears feasible, using low-cost high productivity photobioreactorsphotobioreactors

• Requires tight coupling of biology and q g p g gyengineeringValue of co products must be captured; • Value of co-products must be captured; may approach or exceed value of oil

• Systems modeling/integration required to achieve cost targets
