Key Points

• Cellulosic bioenergy is moving forward rapidly, positioning

underway

• Quality Partnerships

• Syngenta: waste sugarcane (bagasse) to ethanol

• Texas A & M University: cheap/waste sugars to energy

• Queensland University of Technology: using our proprietary INPACT

technology to add valuable enzymes/proteins to energy processes

• Ground floor entry to the commercialisation of bioenergy in

Australasia

• Rights issue price values Leaf Energy at $1.4m

Energy Outlook

• Cambridge Energy Research • Energy shortfall to reach 35 billion barrels per day by 2030

• Gap can’t be filled by fossil fuels

• Political uncertainty in supply exists

• Cellulosic bioenergy is a part of the solution: • Cellulose is most abundant organic material on Earth

• No feedstock “bubble” – waste biomass avoids the food/fuel debate, less volatile pricing

• Can produce a liquid transport fuel

• Renewable and carbon neutral

• Ethanol as a fuel releases 86% less carbon than petroleum

Cellulosic Energy Outlook

• Cellulosic processes close to commercialisation • Demonstration plants are being built in USA, China, Canada and other

countries around the world

• Cost of enzymes dropping

• Positioning is underway

• Mitr Phol takeover of MSF Sugar (Maryborough) to invest in bio-energy

• Oil majors and big enzyme companies are involved

• US Venture capital funds are investors

• Energy pricing predicted to rise

• Government’s supportive and incentives available

Cellulosic Energy in Australia

• Australians spend about $50 billion on energy each year

• 35% of all energy requirements are related to transportation

• Sugar cane has the potential to provide sufficient ethanol for 14% of Australia’s automotive gasoline requirement

• 10% ethanol mandate across Australia = 2,000 ml of ethanol or a $1,400 million market (@ 70 cpl to manufacturer)

• QLD and NSW alone = 1,000 ml or $700 million market

• Current ethanol mandates: NSW 6%, 40% of all petrol sold is E10

• Targets Biodiesel; WA 5% Vic 5%

• GM Australia have recently launched a flex-fuel passenger car which can run on 85% ethanol

• Collaboration between Syngenta, Australian Government, Queensland University of Technology and Leaf Energy

• Phase 1: 2008 to 2011; Phase 2: 2011 to 2014

• Combining Leaf Energy and Syngenta IP together with new joint IP

• Novel technologies covering the complete process; pre-treatment, hydrolysis and fermentation

• Leaf Energy has no outlays for research

• Leaf Energy rights to joint IP in Australasia

• Leaf Energy is also in the process of obtaining patents to joint IP in India, Thailand, the Philippines, Nicaragua and Guatemala

• Success on key fronts:

• “We have developed and demonstrated the pre-treatment process required

to modify biomass so it is more amenable to processing into fermentable

sugars and other higher value bio-commodities” (James Dale July 2011)

• “These results are the first demonstration of the expression and

accumulation of recombinant CBH1, CBH11 and EG in Sugar Cane and

represent a significant first step towards the optimisation of Cellulosic

enzyme expression in sugar cane for the economic production of

Lignocellulosic Ethanol” (Harrison et al, Plant Biotechnology Journal 2011)

• Commercialisation and scaling up activities continue at the Mackay

Renewable Bio-commodities Pilot Plant (a facility owned by and operated by

QUT and available for use by Leaf Energy) with Government support

• Debaryomyces hansenii (Dh) - a marine yeast that can produce

up to 70% oil by bodyweight

• Dh naturally produces and secretes oil

• Salt tolerant (up to 4M NaCl) – minimal sterilisation procedures

• Transformation has been achieved

• Grows on cheap sugars (sucrose, glucose and glycerol)

• Plan is to add a valuable enzyme/protein to oil production using INPACT and develop on a commercial scale
