3 DK 1990! Energirelateret CO2 Global contekst IEA WEO and COP 21 DK 2015: 6,9 ton CO2/capita (energi) Global: 2,1 ton CO2/capita Target: Well below 2 degr. IEA 450 PPM 2 degr. scenario Mission Innovation More global R&D INDC s Energy system scenarios for Denmark & Europe A tough challenge to realise Paris COP21 targets significant CO2-reduction needed 3

4 Uncertainties in international framework conditions (fuel and CO2-prices, focus on green energy etc.) Paris COP21 A need for scenarios to handle uncertainties Energy system scenarios for Denmark & Europe 4

5 Global plans (INDC s) significant grow in wind/solar Kilde: Ecofys, april 2016 INDC s does not lead to needed reduction in CO2 if Well below 2 degr should be realised A need for even more wind, solar, RE-fuels and energy efficiency Energy system scenarios for Denmark & Europe 5

6 Europe a case with wind and solar mix Wind ressources Solar ressources Population densities Smart Energy system compliant with COP21 visions for CO2 reduction Europe A high population density region with a mix of wind and solar ressources - A representative case

7 European scenarios to cope with uncertain future Tyndp 2016 Tyndp 2018 (work in progress) Distributed generation High impact from local prosumer solutions EU on track with 2050 vision High oil prices (IEA New policies) and high CO2 prices 50% electricity from wind/solar in 2040 Global climate action Strong international green framework EU on track with 2050 vision Moderate oil prices and very high CO2-prices (IEA 450 PPM) 50% electricity from wind/solar in 2040 Sustainable Transition EU not fully on track with 2050 vision Low oil/natural gas prices and moderate CO2- prices (IEA Low oil price scenario) Energy system scenarios for Denmark & Europe 7

8 RE-electricity potential ressources DK Socio-economic cost of energy 2030 excl. integration (LCOE) 100 $/MWh Landvind Onshore wind Cost of electricity Offshore wind Bio-CHP Coal-CHP (interval) Power consumption scenarios Onshore wind (high scenario) PV solar Offshore wind (up to 35 m depth) Wave power Offshore wind (more than 35 m depth) Bio CHP Technology data 2014/2015 and 4% discount Solar large scale not illustrated Energy system scenarios for Denmark & Europe 8

9 REgas prce (DKK/GJ) excl. cleaning and upgrade Straw Waste mun. Energycrops Wood Ressources and cost for fuels (2030 if all biomass is allocated to fuels) Today primary used for heat and CHP Marg. bio etc. Slurry etc. Electrolysis (power 2 gas) Consumption of fuels (gas+liquids) Fuels demand today would require more than 30 GW extra windpower if power-to-gas should deliver Fuel production (PJ) 2013 Gasoil + CO2 (2035) Natural gas + CO2 (2035) A significant demand for fuels electrification is needed to solve the fuel challenge Natural gas cheaper than gasoil RE-gas cheaper than biofuels Energy system scenarios for Denmark & Europe 9

16 Summing up The COP21 (Paris) aggreement i very ambitios. A need for very large increase in wind and solar power A high need for electrification heat, transport sector to reduce CO2 and reduce need for fuels A need for fuels (gas/liquieds) for heavy transport, aviation, peak-power A need for further development of new central energy plants suited for wind/solar dominated regions A need for further development of decentralized bio-energy plants (biogas/power-to-gas) solving the energy-agro integration Energy system scenarios for Denmark & Europe 16
