Denmark phase change energy storage

What is the thermal capacity of a Danish heat network?

Danish heat networks with CHP typically operate with a large amount of non-seasonal thermal storage in the form of steel water tanks. In 2013, this was estimated to have a thermal capacity of 50 GWh , while in 2018, seasonal storage capacity (almost entirely PTES) was estimated to be 14 GWh.

Will Denmark phase out natural gas use in 2023?

Denmark had already decided to phase out natural gas use by switching to district heating and heat pumps. Denmark is among the global leaders in biomethane, with around 70 large producers that inject into the gas distribution network. In 2023, the DEA expects gas consumption to consist of 39% biomethane and 61% of natural gas.

Does Denmark have a reliance on fossil fuels?

The district heating sector has practically phased out coal, helping lower the reliance on fossil fuels in Denmark’s total energy supply (TES) from 75% in 2011 to 53% in 2022, well below the IEA average of 79%. Denmark is committed to ending fossil fuel production by 2050.

Is Denmark a leader in decarbonisation?

Denmark has been an early leader in decarbonisation and is inspiring many countries around the world. The technological transformation of Denmark’s energy system is fast and visible, notably in electricity with offshore wind, biomethane, district heating, and carbon capture and storage (CCS) development.

What can Denmark learn from the energy crisis?

Denmark can learn from the energy crisis with a view to prepare for the winter 2023-24, which will require a continuous focus on energy savings, renewables deployment, maximised energy production and the scaling up of clean energy investment. One lesson learnt is that demand-side flexibility can be enabled.

Does Denmark have a potential for underground CO2 storage?

Beyond offshore storage, Denmark is also exploring the potential for underground CO2 storage on land. The country has granted exploration licenses for a land-based reservoir in Jutland, where the lessons learned from Project Greensand will be applied.
