Aquatic Biofuels Presentation

  1. 1. Aquatic Biofuels New Options for Bioenergy Tony Piccolo Fish Utilization and Marketing Service (FIIU) Thesis Topic (MBA - University of Malta – Rome Campus)
  2. 2. <ul><li>What are aquatic biofuels </li></ul><ul><li>Why produce aquatic biofuels </li></ul><ul><li>Conversion systems </li></ul><ul><li>Growth and harvesting </li></ul><ul><li>Potential for developing countries </li></ul><ul><li>Challenges and Opportunities </li></ul>
  4. 4. <ul><li>Why ALGAE? </li></ul><ul><ul><li>Does not compete with agriculture </li></ul></ul><ul><ul><li>High yield per acre </li></ul></ul><ul><ul><li>Contains no sulphur therefore no SO 2 emissions </li></ul></ul><ul><ul><li>Non toxic and highly biodegradable </li></ul></ul><ul><ul><li>Does not require soil for growth </li></ul></ul><ul><ul><li>Uses as little as 30cm of water per year per hectare (open pond system) </li></ul></ul><ul><ul><li>Adaptable anywhere even at great distances from water </li></ul></ul><ul><ul><li>Abatement of CO 2 – carbon neutral </li></ul></ul>
  5. 5. Oil yield per hectare of microalgae significantly exceeds other common oil sources such as soya and rapeseed 39 500 1 190 448 446 1190 39 500 PBR* *PBR – Photo Bio-Reactor 88 times more than soya 33 times more than rapeseed
  6. 6. <ul><li>Photo Bio-Reactors? </li></ul><ul><li>Using Photo Bio-Reactors is expensive </li></ul><ul><li>but it is a State of the Art Technology, it </li></ul><ul><li>produces higher yields than other systems. </li></ul><ul><li>However, Development and Processing costs are still quite high and perhaps not suited yet for developing countries. </li></ul>
  7. 7. Microalgae Biofixation Process – with wastewater
  8. 8. Open pond wastewater has demonstrated productivities of 100 tonne/ha/yr tonne per hecatre per year.
  9. 9. <ul><li>Costs and key performance parameters for Open Pond biofixation systems for GHG abatement are: </li></ul><ul><li>Land capital, cost of ponds, harvesting, processing, water supply, infrastructure + operating costs (around US$120/tonne) </li></ul><ul><li>Raceway mixed ponds capital costs of about US$100,000 per hectare </li></ul><ul><li>Availability or transport of flue gas and/or waste water to the ponds </li></ul><ul><li>Algal productivity / harvestability / processing </li></ul><ul><li>Product values: biofuels, GHG abatement, reclaimed water, fertilisers, other </li></ul><ul><li>co products. </li></ul><ul><li>Caution – With present technology fuel only algal systems are not plausible on their own - they require additional revenues. </li></ul>
  10. 10. Adaptability to developing countries – other key factor requirements Algae production with Photo Bio-Reactors (PBR) More suitable for Higher Income Countries (due to higher start-up costs) Algae production with MBP (Microalgae Biofixation Process) More suitable for Lower Income Countries (due to lower start-up costs)
  12. 12. <ul><li>FISH WASTE – From Aquaculture Farms </li></ul><ul><li>Press the fish waste </li></ul><ul><li>Oil is extracted through a water separation process at 90 o C </li></ul><ul><li>  </li></ul><ul><li>Manganese (Mn), methanol (9%) and caustic soda is added. </li></ul><ul><li>The by-product glycerine is sold to the cosmetic industry and the residues are made into fishmeal. </li></ul><ul><li>1kg of fish waste can produce just over 1lt of bio-diesel. </li></ul>
  13. 13. Aquafinca - Honduras Agifish – Viet Nam
  14. 15. <ul><li>Fish Waste - Key points and feasibility for developing countries </li></ul><ul><li>Technology is adaptable and transferable in many developing regions. </li></ul><ul><li>It can provide livelihoods through the production of fish, and produce local energy free from GHG emissions.    </li></ul><ul><li>Relatively little investment required. </li></ul><ul><li>Fish waste could also promote more efficient utilization of aquatic living resources and generate additional income for fishers' and fish farmers' communities. </li></ul><ul><li>Adaptable on large fishing trawlers.    </li></ul><ul><li>Fishing Ports </li></ul>
  15. 16. <ul><li>Aquatic Biofuels – Challenges, Opportunities and Gains </li></ul><ul><li>Algae </li></ul><ul><li>Cost intensive especially for Photo Bio-Reactors may be suitable for Higher Income Countries. </li></ul><ul><li>Open pond systems are much more viable although real costs are still not available, by-products can however make the process completely viable. </li></ul><ul><li>Abatement of CO2 Mitigation from the conversion of the algal biomass to renewable fuels – directly substituting fossil fuels – coal and gas </li></ul><ul><li>Each tonne of microalgae biomass produced = about a tonne of CO2 abated </li></ul><ul><li>Both algal to bio-fuel technologies are therefore completely Carbon Neutral </li></ul>
  16. 17. <ul><li>Fish waste </li></ul><ul><li>The oil produced for bio-diesel is already marketable as fish oil, more fish oil </li></ul><ul><li>would have to be produced to cater for the demand in bio-diesel this may disrupt fish oil markets. </li></ul><ul><li>The technology is in place and is transferable to other developing countries as pilot project studies. </li></ul>
