The energy system – shift of paradigm



2011 – 25 % wind power in the electricity supply 2025 – 50 % RES – most wind power - equals 18 TWh wind power a year for Denmark But 50 % wind power is just a step stone – The Danish goal is non-carbon energy supply 2050 – 100 % RES in the energy supply – calls for electrification The high penetration of wind power calls for balancing and storage facilities The non-carbon future calls for coherent solutions electricity and gas partnership

Wind power


Wind power covers the entire demand for electricity

In the future wind power might exceed demand

in 200 hours (West DK)

in more than 1,000 hours

Effective Wind power integration using:

  

Robust Transmission grid – with strong interconnectors Coherent energy system with high flexibility Intelligent control using Smart Grid applications strong prioritizing for 2025 Production

Means and solutions

+ 50% ? 50% Wind


Robust transmission grid, strong interconnectors and market integration

Flexibility in demand and production – cooperation with the heat- and transportation sector Smart Grid for efficient control and market based regulation of the power system – integrating of all local DER many based on gas

Smart Grid is the future

Smart Grid – puzzle to the future RES electricity system

CHP and gas for balancing the power system CO2 neutral Input resources Municipal waste Biomass Solar heat Geothermic heat Agricultural waste The Gas system Biogas Biogas – upgrade Thermal gasification RE-Gas Hydrogen

Heat system RE-Heat District heat CHP - flexibility Poly Generation Bio fuels High value Storable

Electricity grid Grid connection Marked participation Prosumer facility Ancillary services Fast regulation

2025 Strategic goals for the coherent energy Wind power as the major non-carbon RES supply - Calls for other sources of flexible and regulation power

Existing power plants with fossil fuels (coal) are closing down - The electricity grid need ancillary services from CHP units

Surplus of electricity in 900 – 1.200 hours a year - Calls for new consumption – Heat and Transportation (EV)

No wind production in many hours a year - Calls for strong interconnectors to neighboring countries

Intelligent use of Biomass – biogas and other bio resources - Bio resources must be utilized with maximum benefit - Electricity production - District heat production - Storable Bio fuel and RE-Gas

CHP units with Poly Generation is the future

Coherent energy planning for 2050

Coherent planning of the power and gas systems 2050 

Four possible track towards fossil free future: Wind power – Biomass – CDM or CCS

Examine the consequences for the power and gas infrastructure, security of supply and market by 2050

Contribute to a robust platform for decision making

Danish Climate Commission The Wind Track It is possible to run the power system at 100 % RES and wind power as main supplier – with…  Strong interconnectors  Wind to heat conversion  Wind to gas conversion  Full Smart Grid dissemination

Recommends priority for wind power and other fluctuating power generation as the major RES

In 2050 with 100 % RES fluctuating power production there are massive need for flexible and new consumption – and storage capacity vision for the future - 2050 Production

Means and solutions


Strong interconnectors and market coupling to Europe

Coherent energy systems, cooperation between gas, electricity, heat and transport

100 % RES

+ Intelligent energy using smart grid, gas fired CHP units and flexible demand

+ Gas storage

Conversion of electricity to gas for quantitative storage for later use in CHP units to new electricity production

Integration of wind power – cooperation between gas and electricity Electricity grid Low electricity price

Key messages; Utilization of Electricity and gas cooperation Competitive peak-load capacity from RE-Gas conversion- Turbines, FC or CC Will contribute to the integration of fluctuating RES – Wind power Optimal use of bio resources Substantial storage capacity in the gas sector at low costs

The future is already tomorrow – in Denmark The Climate agenda is unchanged -

The EU and Denmark will reach ambitious goals by 2020

30 % RES in the energy system ≈ 50 % RES electricity in Denmark 2025 -

The Danish focus is primary on Wind power and Biomass

50 % RES from electricity is just a step stone -

Denmark is aiming at reaching 100 % RES by 2050

Intelligent power system is one of the corner stones -

Electricity as the primary energy carrier – cooling, heat and transport


Strong Interconnectors and Market integration on European scale


Smart Grid allows integration of mutual RES


Gas fired CHP units for fast reserves and ancillary services


RE-Gas production and large storage facilities for the gas system strategy:

The worlds best RES based power system by 2025 - step stone towards non-carbon energy system by 2050
