2 CSP in Spain Cayetano López CIEMAT Director General December 2011

3 The serious drawbacks of the existing energy supply scheme Imply a change whose main vector is: Reduce the carbon content of the primary energy sources Energy saving and efficiency increase Less fossil fuels More renewables More (at least keep) nuclear (Fukushima accident?, Gen IV?) Possible clean use of coal (CO2 capture and sequestration) Fusion (not available in the short term) None of these alternatives are free of problems. To implement them, a big effort in technology development and political support is necessary. The elements of change in the energy paradigm

4 Electricity Generation in Spain, 2010 Renewables: 35 % Natural Gas, 32 % Nuclear, 20 % Wind, 15 % Hydro, 14 % Coal, 8 % Oil products, 5 % Solar, 3 % Biomass & Waste, 3 %

5 CO2 emissions by unit of electricity produced Renewables in 2010: 11,3% in Primary Energy 13,2 % in Final Energy 35 % in Electricity 5 % biofuels Renewables in the Spain energy supply

6 The solar resource Solar energy is plentiful but diffuse In good conditions, the daily averaged incoming solar flux is around 220 – 250 W / m2 which, integrated, gives a yearly primary energy of around 2000 – 2200 kWh / m2. This is equivalent to a rain of about 20 cm of oil per annum and m2. 1,2 barrel/(year x m2)

7 With Spain at the Epicenter, Global Concentrated Solar Power Industry to Reach 25 GW by 2020 Cambridge, Massachusetts, 28 April Led by development in Spain and potential in the US, concentrated solar power markets are entering a new growth phase, amidst a tumultuous global economic landscape. The CSP industry is scaling rapidly with 1.2 GW under construction as of April 2009 and another 13.9 GW announced globally through 2014, according to a new study from Emerging Energy Research analyzing global CSP markets and strategies. Spain is the epicenter of CSP development with 22 projects for 1,037 MW under construction, all of which are projected to come online by the end of Despite only 75 MW of CSP under construction, the US continues to offer significant opportunity for CSP, with 8.5 GW in the pipeline and scheduled for installation by Attracted to promised lower costs, US utilities have turned to CSP -- through both Power Purchase Agreements and direct ownership -- to meet their Renewable Portfolio Standard mandates. CSP prospects in Spain, 2009

8 CSP in the world (July 2011)

24 Over-cost derived from the subsidies to RES

25 Other financial data RES Export – Import = M (2015) to M (2020) Avoided emissions = 171 Mt CO2 Jobs related to RES in 2020 =

26 Thank you !!!

27 MENA-Europe Complementarity The Desertec and the Mediterranean Solar Projects

28 Renewable Energies Problem 1: High Cost Possible solutions: Increasing size of the plants Advances in R + D Improvements in component manufacture Series production (market expansion) Experience in O & M Problem 2: Intermitency Possible solutions: Hybridation Energy storage (electricity, heat, H 2 )
