3. Slide 3: Carbon Nanotube Project

   Carbon Nanotube Project UQ/ Eden Developed Pyrolysis Process-CNT/CNF from Natural Gas For personal use only (Eden 100%) CH4 + Catalyst + Heat = C + 2H2 • Produces only CNT + H2 - no CO2 • Multi-walled carbon nanotubes:  tensile strength - 200-300x steel  approx. 17% the weight of steel  high elec

4. Slide 4: Eden Energy CNT/CNF Production

   Eden Energy CNT/ CNF Production For personal use only Hydrogen Product Catalyst Feed Reactor Natural Gas Supply Hydrogen CH4 Carbon CNT’s Carbon Product

5. Slide 5: Eden's CNT/CNF Production Capacity

   Eden’s CNT/CNF Production Capacity For personal use only • Eden’s Commercial Scale Reactors in Denver, USA • Scalable, modular reactors • Capable of producing <40 tonnes of CNT/ year • Low cost catalyst production • High quality/low cost CNT/CNF

6. Slide 6: Concrete

   CNT in Concrete For personal use only • Significant global research conducted over past 5-8 years • Monash University (Melbourne) - Collaboration  Ongoing collaboration since 2011 • US Consultant (Denver, Colorado)  Assisting Hythane Co in testing and developing US market  Is arranging initial US

7. Slide 7: Concrete – Results to Date

   CNT in Concrete – Results to Date For personal use only • CNT Concrete - 0.5 % CNT : 99.5% cement concrete  < 30% increase in compressive strength of cement  < 14% increase in tensile strength of cement  CNT act as nucleation points for cement hydration resulting in denser, tougher, less permeabl

8. Slide 8: Fresh Cement Paste

   CNT in Fresh Cement Paste For personal use only Build-up of dense, hydrated cement on surface of CNT (top right) • CNT provide:  nucleation points for cement hydration  nano-scale fibre re- enforcement. • CNT facilitate denser, stronger and potentially more durable concrete. • Other larger-scale f

9. Slide 9: Fractured Hardened Cement Paste

   CNT in Fractured Hardened Cement Paste For personal use only CNT bonded in hardened cement paste after fracturing Note: ends of CNTs are well- bonded within cement gel and provide anchorage Monash University Helium Ion Microscope Image

10. Slide 10: Concrete - Benefits

    CNT in Concrete - Benefits For personal use only • Benefits – denser, stronger, tougher cement  Mixed into liquid surfactant and added during batching process  less concrete needed  Less (or perhaps no) steel re-enforcing  abrasion resistant- lower maintenance costs  denser, less permeability 

11. Slide 11: Concrete - Applications

    CNT in Concrete- Applications For personal use only • Global Applications  Abrasion Resistance o road and bridge surfaces o pavements , warehouse/factory floors  Increased Compressive and Tensile Strength o high rise buildings, bridges,  Lower Permeability o dams, spillways, o sewer /water pipeli

12. Slide 12: Global Concrete Market

    Global Concrete Market For personal use only • Global concrete/ cement market- US$450 billion/year  Approx. 1 tonne of concrete produced annually for every person  Cement production creates 5% of annual global GHG emissions  CNT concrete could reduce cement requirements by >15-30% • USA - initial

13. Slide 13: Future Large Scale CNT Production

    Future Large Scale CNT Production For personal use only • 1,000 tonnes p.a. CNT capacity reactor  sufficient for > 1.7 million tonnes concrete -7% of Australian market • 10,000 tonnes p.a. CNT capacity reactor - Natural Gas Fired Power Stations - Fertiliser Plants  500 MW station uses >100,000 tpa

14. Slide 14: Challenges and Marketing Plans

    Challenges and Marketing Plans For personal use only Challenges • Extension of shelf life of admixture development underway • OH&S concerns resolved  CNT in low concentrations (< O.5%) in liquid admixture  CNT used in low concentrations and is firmly bonded with cement Marketing Plans • Global man
