A recent study from EASAC (the European Academies Science Advisory Council) examines how far CSP can help the EU reach its target of all electricity being produced with zero emissions of greenhouse gases by 2050. It concludes that CSP could make a significant contribution to this target but four problems need to be overcome:
1. Costs – currently 2-3 times higher than fossil fuels but are expected to come down.
2. Location – Plants are most effective in hot, dry locations but they currently need large amounts of water.
3. Infrastructure – grid lines will have to be improved between Europe and the Middle East and North Africa.
4. Security – in protecting these lines and plants.
