  1. Feasibility Study of a Proposed Agrobusiness Solution for the Veenkoloniën Area commissioned by Froukje de Boer, Xiangming Chen, Victoria Naipal, Hanna Rövenich, Bart van Stratum Haregot Haile Zerom

  2. Introduction • Future Veenkoloniën: climate change, intensifying irrigation • Expected water shortage for irrigation • Proposed solution: water storage basins • Loss of agricultural area: compensate loss of income • Creation water storage • Solar energy • Algae cultivation (technical) feasibility? Introduction - Basin - Energy - Algae - Integration - Conclusion

  3. Methods • Three individual concepts => three working groups • 1) Individual study subjects + + = .... 2) Integration Introduction - Basin - Energy - Algae - Integration - Conclusion

  4. Water Basins

  5. Water Basins • Future water demand: 100M m3 (now) => 175M m3 (future) • Storage: regional vs local • Study area: farm with 100 hectare of land • Per m2 of agricultural land: 74 mm • Total storage: 55,000 m3 • Determining the basin dimensions: • Depth determines area needed • Per m2 of basin: precipitation, evaporation, seepage Introduction - Basin - Energy - Algae - Integration - Conclusion

  6. Water Basins • Volume at 1st of April sufficient to supply 74 mm of irrigation evaporation precipitation irrigation basin leakage ditch Introduction - Basin - Energy - Algae - Integration - Conclusion

  7. Solar Energy

  8. Solar Energy: Construction sensitive to movements Inefficient for the Netherlands best solution • Mounting: fixed vs floating • Floating: least expensive, but allows movement Photovoltaic (PV) cells: best solution for Veenkoloniën Introduction - Basin - Energy - Algae - Integration - Conclusion

  9. Solar Energy: Economics Small scale (<15 kWp) Individual scale: ~100 m2 Economically profitable Payback time: ~10 years Large scale (>15 kWp) Large scale: ~1,000-10,000 m2 Economically balanced Uncertainty depending on subsidies (SDE) Use partly for own energy need Sell excess to electricity grid Introduction - Basin - Energy - Algae - Integration - Conclusion

  10. Algae Cultivation

  11. Algae Cultivation • Why algae? • Environmentally friendly (CO2 neutral) • Biofuels, feed and food, electricity (H2), cosmetics, bio-plastics, ... (+) Controlled conditions (+) Easy to scale up (-) Small surface (+) Highest productivity (+) Controlled conditions (+) Optimal light impact (-) Contamination (-) Difficult to control growth parameters (-) Light conditions non-homogeneous Introduction - Basin - Energy - Algae - Integration - Conclusion

  12. Algae Species • Species: Neochloris oleoabundans • High oil content (up to 40% under nutrient starvation conditions) • Biomass areal productivity: 16.5 g/m2/day • Fresh water organism • Can grow in wastewater and on waste CO2 Introduction - Basin - Energy - Algae - Integration - Conclusion

  13. Algae Application • Dimensions: • 4,444 reactors/ha • 110 L/reactor • 16.5 g/m2/day • → ~70,000 kg/ha/yr • Biomass composition: • 40% lipids • 50% proteins • 10% carbohydrates • Price: 1.65 €/kg • Production cost: 0.5 €/kg* Introduction - Basin - Energy - Algae - Integration - Conclusion

  14. Integration

  15. Integration irrigation water pumping cooling PV electricity (external) electricity biomass CO2 reduce evaporation wastewater

  16. Integration #2 • Floating greenhouse => reduction of evaporation biogas installation starch industry waste water CO2 biomass controlled environment 2.5 - 3 m height

  17. Conclusions • Water storage: technically feasible, economic feasibility uncertain • Solar energy: • Technically feasible • Economic feasibility: depending on scale and subsidy • Algae: technically feasible, economic feasibility uncertain • Integration: creates technically feasible, energy-neutral system • Economic feasibility needs further study Questions? Introduction - Basin - Energy - Algae - Integration - Conclusion
