ABENGOA BIOENERGY
Abengoa is a technology driven company committed to sustainable development
• In the early nineties Abengoa identify Bioenergy particularly bioethanol as a significant business opportunity due to the advent of biotechnology and the energy trends in the transport sector
• In 1995 we entered the business with our first biorefinery in Cartagena Spain and a commitment to develop technology to enable the future biomass opportunity.
• Presently we are operating six biorefineries, with two more under construction, and a very aggressive growth plan that includes new biomass technologies.

ABENGOA BIOENERGY
There are two different families of technologies for the transformation of conventional and modified raw materials into energy and chemicals
• Termochemical processes convert raw materials into pyrolysis oils or syngas
• Biochemical processes convert raw material into intermediate sugars
• The intermediate products are converted to fuels, chemicals, and co-products

ABENGOA BIOENERGY Production Process
Technology based in fermentation of sugars
Sugar (glucose)+ Air CO2 + Ethanol
C6H12O6 + O2 3 CO2 + 3 C2OH6
Yeast
Used feedstock is transformed into sugars, the process would change depending on the chemical composition:
�Sugar beet or sugar cane: direct fermentation
�Cereal: starch, previous saccharification (enzymes)
�Lignocellulosic biomass: cellulose and hemicellulose. Hydrolysis to break long chains and produce C6 and C5 sugars
Level of
ComplicationFeedstock
price
Each feedstock yields different co-products

Enzymatic hydrolysis technology – current situation
� Abengoa Bioenergy has develop a proprietary fractionation technology for biomass processing.
� Pilot scale plant in York, (Nebraska, US) to validate our biomass fractionation process and integrate downstream systems
� Demonstration plant in Babilafuente (Salamanca, Spain) to validate
� biomass to ethanol enzymatic technology at a commercial scale.
Enzymatic technology – Future situation
ObjectiveCompetitive production of ethanol from biomass.
StepsComplete the process engineering development
demonstrations phases.� Build first of a kind commercial facility after the demonstration of the technology in Salamanca and Nebraska� Valorization of all biomass fractions

ABENGOA BIOENERGY
Steps (continue)
Research in the biological deconstruction of the biomass to produce tailor made enzyme mixes for each specific case:
� Determine fundamental physical and chemical factors in the recalcitrante of lignocellulosic biomass to processing
� Understand cellulase and cellulosome� Develop new enzymatic systems to soften termochemical
pretreatment conditions
Advance in the sugar fermentation to ethanol through the engineering of microbial systems to achieve:
� high yield with complete sugar utilisation, minimal by- product formation, and minimal loss of carbon into cell mass.
� high final ethanol concentration � tolerance to inhibitors present in hydrolysates � higher overall volumetric productivity, especially under high solids

Biomass gasification and synthesis (BtL) technology –current situation
�Available catalysts are not productive enough to make the
process economically feasible.
�Low conversion per pass
�Mixed alcohols product with low ethanol selectivity
�Several existing technologists licensing gasification processes
for syngas production for further chemical synthesis.
�Catalysts development programs in European research centers,
combined with process design and analysis.
�Recently granted by the US-DOE a program (3 MM$) for
synthesis catalysts development

Hybrid-plants technology – current situation
� Abengoa Bioenergy is developing a biorefinery concept based on knowledge accumulated from our technology development program.
� ABRD is developing the first commercial hybrid facility integrating cereal technology, enzymatic hydrolysis technology and gasification technology to produce fuels, energy, electricity and
coproducts.
Hybrid plant technology – Future situation
Objective� Achieve maximum thermal integration between technologies� Achieve maximum integration between different process streams and process operations� Valorize all process streams
Steps� Integrate EH technology and cereal technology. Gasification technology only to provide heat and
power� Improve and demonstrate concept to produce ethanol and other valuable products from syngas.
