  1. Biomass to Energy Assessment St. Kitts & Nevis Mark Lambrides (OAS/DSD) Kevin de Cuba (OAS/DSD) Pre-conclusions December, 2006

  2. Why does sugar matter? • Shutdown of the sugar industry • Unemployment • Decreased sources of income • Lost benefits of sugar crop (tradition, erosion, tourism) • Traditional energy supplies • High cost of diesel import for electricity generation • High cost of transportation fuels • Dependent on external geo-political forces • Negative environmental impacts (local and global) • Increased reliability of electricity supplies • Current waste management • Health impacts • Environmental impacts • Landfill space constraints

  3. Current state of the sugar industry

  4. Current state of the energy sector • Electricity Transportation fuel

  5. Current state of waste management

  6. Objectives • Determine if there is reliable biomass feedstock supply for long term ethanol and/or electricity production • Highlight commercially viable biomass to energy conversion approaches • Outline potential strategy for public-private partnership to develop biomass to energy • Attract commercially proven developers to consider investment approach in SKN

  7. Methodology of study • Biomass resource assessment • Technology identification and selection • Design of multiple scenarios • Techno-economic analysis • Sensitivity analysis • Results summary • Recommendations – Outline a commercial development pathway

  8. What do we know? Sugar cane/ bagasse data (1)

  9. What do we know? Sugar cane/ bagasse data (2) [1] Van Groen, M., “Energy rooted in sugar cubes”, The interaction between energy savings and cogeneration in Indian sugar mills, Utrecht University, 1999 [2] Hassuani et al., “Biomass power generation”, Sugar cane bagasse and trash, UNDP Brazil, 2005, page 26 [3] Hassuani et al., “Biomass power generation”, Sugar cane bagasse and trash, UNDP Brazil, 2005

  10. What do we know? Municipal waste data

  11. Scenario A – Ethanol (from SKN sugar)

  12. Scenario B – Electricity and Cane Juice

  13. Complimentary Alternatives • Add BMW as feedstock (A & B) • Import hydrated ethanol from Brazil, create larger facility, feed in imported and local product to produce ethanol • Manufacture other derivatives

  14. Critical challenges • Available land for sugarcane production (currently ~6,000 acres, optimal 10,000 acres) • State of sugarcane harvesting system • State of sugar processing system • SIZE MATTERS….

  15. What's next: Steps to commercialization • Remainder of this week - data gathering interviews with stakeholders in St. Kitts and Nevis • Preparation of preliminary assessment • Final Draft expected by end of January ´07 • Stakeholder review and comment on final draft • Presentation of findings • Initiative to facilitate commercial development (international tender; short list tender; sole source)

  16. Bio-Energy Potential St. Kitts
