3. www.fhi-berlin.mpg.de The wall: why store the sun on earth? 3

4. www.fhi-berlin.mpg.de The sun-gap…..bricks in the wall Thermo-mechanical storage is too ineffective 4

5. www.fhi-berlin.mpg.de What we find… 5 We break the wall by creating artificial solar fuels like nature uses sugar

6. www.fhi-berlin.mpg.de...behind the wall 6

7. www.fhi-berlin.mpg.de Can we split the water? 7 We use catalysts like nature does in photosynthesis: We need high performance systems

8. www.fhi-berlin.mpg.de Can we make the solar fuel? 8 We need a catalyst with structural and electronic modifiers Then we can form methanol and transportation fuels and polymers

9. www.fhi-berlin.mpg.de We break the wall….. 9

10. www.fhi-berlin.mpg.de … when we keep on remodelling the energy system 0.17% of the earth surface receives all energy needs of mankind. Collect now solar energy by a combination of physical and chemical technologies. Store large amounts of this energy in chemical bonds. Complete and expand existing knowledge into a fundament of technologies. Price and prejudice: You need to support their implementation! 10
