Presentation Transcript

  1. Work Packages: 1. Technologies (combination of CSP and desalting technologies) 2. Water and Solar Energy Resources 3. Demand Side Scenario 4. CSP Market Potential 2000-2050 5. Socio-Economic Impacts 6. Environmental Impacts 7. Literature

  2. WP 5: Socio-Economic Impacts CSP Learning Curves PR = 0.8 - 0.9 Source: NEEDS 2007

  3. WP 5: Socio-Economic Impacts CSP Learning Curves 5 % interest rate 25 years life 2400 kWh/m²/y irradiance

  4. @ 0.5 €/m³ water cost WP 5: Socio-Economic Impacts CSP Learning Curves @ 5 ct/kWh electricity cost

  5. WP 5: Socio-Economic Impacts The Cost of Not Acting

  6. WP 5: Socio-Economic Impacts The Cost of Not Acting Cost of: CSP/Desalination 1.5 - 0.3 €/m³ Savings Irrigation 0.2 €/m³ Savings Domestic 0.4 €/m³ Savings Industrial 0.2 €/m³ Wastewater Re-use 0.1 €/m³ Not-Acting 0.6 - 1.8 €/m³ Total GDP Lost: 11 B$/y

  7. WP 5: Socio-Economic Impacts Urbanisation versus Rural Development Urban settlements with over 5000 inhabitants Recent analysis by World Bank, WWF etc. state that seawater desalination is no sustainable solution  contradiction to literature

  8. WP 5: Socio-Economic Impacts Conclusions • Cost perspective of CSP desalination is affordable (< 0.4 €/m³), while that of conventional desalination is not • Efficiency enhancement and desalination are less expensive than not acting • „Solar“ water can avoid dependency on „virtual“ water • CSP desalination can create arable land for rural and urban development  CSP desalination is a totally over-looked solution to the MENA water crisis
