11 Energy is NOT religion There is no all-mighty technology Renewable Energy diversity is required like bio-diversity The right technology for the right purpose at the right time gives the best economy and performance

12 Energy production The consumption curves Solar and Wind Energy vs Consumption 4 3,5 3 2,5 2 1,5 Solar energy Wind energy Consumption 1 0, FUTURE RE PLANTS MUST HAVE STORAGE TO BE DISPATCHABLE

29 EUDP project proposal 1 Marts Lave et Demo anlæg med to smeltet salt tanke der henholdsvis opvarmes af EL og afkøles ved at energien bruges til at generer overhedet damp 100 bar 540ºC El-opladning og afladning bestemmes ud fra El spot markedet DK1 samt deltagelse i relevant regulerkraft. Energi Energy planning

30 EUDP project proposal 1 Marts Overordnede mål er : 1) Vise gennem EnergyPRO modellering, at bidrag til den grønne omstilling, kan være rentabelt. 2) Eftervise at systemet virker og processen kan styres, samt anskueliggøre at systemet kan skaleres til Giga Watt størrelse 3) Eftervise at lagerets proportioner bevirker at der kan skabes ekstra indtægter ved hhv at være til rådighed både til at aftage samt levere elektricitet on demand 4) Eftervise at nedgravede tanke kan benyttes og de er mere pålidelige i drift og billigere end højtlegerede ståltanke. Dette i samarbejde med Hydro og Kyoto Norge. Energi Energy planning

31 Aalborg future Hvad har højest prioritet for vores fremtidige energiinvesteringer? Grøn varme? -Skal vi lade el være el og droppe at forsøge at være selvforsynende?? Vi kan jo altid købe EL fra de omkringliggende lande, Tyskland og snart England og derimod koncentrere os om at lave varmt vand ved solenergi og varmepumper. Grøn EL? -Har det værdi at kunne optage og gemme energi fra grøn elektricitet, for på et senere tidspunkt, at kunne leverer en del af det tilbage på nettet, og i processen erstatte elektricitet lavet på kul og samtidig fremstille en stor del af varmebehovet. SVARET ER FORHÅBENTLIGT BÅDE GRØN VARME OG GRØN EL
