Paths to a fossil free energy supply

Location | May 2010 - September 2010

An analysis performed by Ea Energy Analyses for DONG Energy and Vestas Wind Systems showed how the development of the energy supply in Denmark and the neighbouring regions can become carbon neutral towards 2050.

The analysis was based on the assumption that the carbon emissions from supply of electricity and heat in Denmark, Germany, Norway, Sweden and Finland should decrease from current levels to zero in 2050. The main question in the calculations was how to achieve this emission reduction in the most cost effective way.

Basis for large investements in transmission interconnectors

The calculations were especially interesting when it came to expansion of the transmission grid and building of new connections within the region. The analysis showed economic benefits even from large investments in new connections. An estimated investment of DKK 125 billion would generate annual savings of DKK 15 billion, thus the annual operating benefits would outweigh the investments in the transmission grid with a good margin.

Expansion of the transmission network turned out to be not just good economy. According to the analysis, it would also make it more attractive to increase the exploitation of the major wind power resources in the North for the benefit of the entire region.

Wind power and biomass

The analysis concluded that converting the entire region to a carbon neutral energy supply is an appreciable but manageable task with wind power, biomass and hydropower as key technologies.
