An analysis performed by Ea Energy Analyses for DONG Energy and Vestas Wind Systems shows how the development of the energy supply in Denmark and the neighbouring regions can become CO2-neutral towards 2050.
The analysis is based on the assumption that the CO2 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 is how to achieve this emission reduction in the most cost effective way.
The calculations are especially interesting when it comes to expansion of the transmission grid and building of new connections within the region. The analysis shows economic benefits even from large investments in new connections. 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 is 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.
The analysis concludes that converting the entire region to CO2-neutral energy supply is an appreciable but manageable task with wind power, biomass and hydropower as key technologies.
