FINAL CONFERENCE RABAT, 18-19 MAY 2010
The Role of CSP in Desalination
• Energy Source is large enough to cope with Demand
• CSP mitigates Energy Cost Escalation Risk
• Solar Energy avoids Chemical Additives
• CSP enables Solar Base Load Operation
• CSP can fight Desertification
• Multi-Purpose Plants for New Desert Communities
