2 AGENDA FutureGas Gas As An Integrator Of Renewable Energy The Case Of Denmark 1. International outlook International and European scenarios 2. The situation today gas in the Danish Energy System 3. Transitions of the gas system towards renewable energy 4. FUTUREGAS project - R&D areas for the gas-system 5. Summing up FutureGas Gas As An Integrator Of Renewable Energy The Case Of Denmark

3 GLOBAL CONTEKST IEA WEO AND COP 21 Global: 2,1 ton CO2/capita Target: Well below 2 degr. IEA 450 PPM 2 degr. scenario Mission Innovation More global R&D European set plan to reduce at least 80% CO2e in 2050 Danish Governmental decition to be fossil independent in 2050 A danish target in 2030: 50% of energy based on renewables FutureGas Gas As An Integrator Of Renewable Energy The Case Of Denmark

4 ENTSO-E/G SCENARIOS (TYNDP18 DRAFT) 2020 Best estimate 11% 4% Best estimate 14% 6% Distributed Generation Distributed Generation 15% 15% 25% 25% The EUCO scenario 21% 9% Global Climate Action 34% 17% External from European Commission Bottom up Top Down System share of wind System share of solar power SUSTAINABLE TRANSITION DISTRIBUTED GENERATION GLOBAL CLIMATE ACTION Sustainable Transition 19% 7% Sustainable Transition 27% 10% Very large amounts of wind and solar in all three ENTSO-E/G scenarios (37-50% wind/solar) FutureGas - Scenario analysis

5 ANNUAL ENERGY FLOW IN DANISH ENERGY SYSTEM 2013 Energy ressources Energy system Energy services Gas today primarily used for: Power/CHP/district heating Proces heat industry/service Building heating FutureGas Gas As An Integrator Of Renewable Energy The Case Of Denmark

6 RE-ELECTRICITY RESSOURCES DK SOCIO-ECONOMIC COST OF ENERGY INTEGRATION (LCOE) Landvind Onshore wind Cost of electricity Offshore wind Bio-CHP 100 $/MWh Coal-CHP (interval) Onshore wind (high scenario) Offshore wind (up to 35 m depth) Offshore wind (more than 35 m depth) Power consumption scenarios PV solar Wave power Bio CHP Technology data 2014/2015 and 4% discount Solar large scale not illustrated Very large ressources for wind-power production compared to consumption FutureGas Gas As An Integrator Of Renewable Energy The Case Of Denmark

7 REgas prce (DKK/GJ) excl. cleaning and upgrade RESSOURCES AND COST FOR FUELS (2030 IF ALL BIOMASS IS ALLOCATED TO FUELS) Fuels demand today would require more than 30 GW extra windpower if power-to-gas should deliver Waste mun. Wood Straw Marg. bio etc. Slurry etc. Energycrops Electrolysis (power 2 gas) Consumption of fuels (gas+liquids) 2013 Price: Gasoil + CO2 (2035) Price Natural gas + CO2 (2035) Fuel production (PJ) Very large demand for fuels compared to RE-ressourcer A high need for electrification and efficient use of biomass FutureGas Gas As An Integrator Of Renewable Energy The Case Of Denmark

8 POWER-TO-GAS PERSPECTIVES RE-gas Methan BIOtGas (biogas) Methan (SNG) BIOtGAS (thermal) Synthesis gas DME Methanol Synt. Gasoline/ diesel Power-to-Gas Alkal./SOEC Hydrogen Legend: CH4 H2 FutureGas Gas As An Integrator Of Renewable Energy The Case CO Of Denmark PE plast etc. Fertilizer (ammonia) Combining Biogas and Power-togas is a key task for gas system

9 INTEGRATION OF LOCAL AND NATIONAL GAS-SYSTEM New types of RE gasses to be integrated essential to handle sub-nets with other gas-specification FutureGas Gas As An Integrator Of Renewable Energy The Case Of Denmark

10 DENMARK A SCENARIOS TOWARDS TOWARDS RE-BASED ENERGY SUPPLY IN 2050 HP EV/PHEV P2G HP Industry-HP A need for electrification of all sectors to obtain RE-targets The gas system essential to produce RE-fuels for non electrified services FutureGas Gas As An Integrator Of Renewable Energy The Case Of Denmark

11 PJ A POSSIBLE SCENARIO FOR GAS CONSUMPTION Proces Erhverv Transport El Power/CHP og varme Heating Husholdning A significant reduction of gas use towards 2030 and 2050 Heavy transport and ship might be a large new customer FutureGas Gas As An Integrator Of Renewable Energy The Case Of Denmark

16 SUMMING UP The Paris COP21 is very ambitios a very large amount of RE is needed (wind,solar,biomass) EU target 80% CO2e reduction in Denmark has a target on fossil independent in 2050 The North-Sea region is expected to be highly dominated by wind and a strong grid and efficient integration with heat and gas-system (Power-to-gas) is essential for balancing the power-system Fuels will be needed for backup power, proces heat, heavy road transport and ships (LNG) The gas-system is a key component in integration of wind/solar and biomass to deliver RE-fuels The gas system can deliver very large amount of storage capacity, needed for balancing the fluctuating wind/solar FutureGas i an R&D-project lead by DTU.
