The output of the project can be divided into two main areas. Firstly, results related to the further development and integration of existing tools and methodologies into coherent energy and environmental analysis tools. Secondly, results related to the analysis of future sustainable energy systems.

The result of the CEESA project includes the following highlights:

Tools and Methodologies:

  • Further development of several existing tools such as vehicle drive cycle analysis and energy systems analysis tools including implementation of abilities to analyse new biomass conversion technologies and combined hour balances of storage and exchange of bio(syn)gas as well as electricity.
  • Development of a new CEESA transport scenario tool
  • A method for qualitative modelling of electricity system control structures and a tool for evaluating control resource use in scenario studies
  • Further development of the methodology basis for combining energy system analysis with life cycle assessment.

Modelling and Analyses:

  • Development of biomass resource scenarios and review of potential biomass conversion technologies
  • Design and modelling of a transport scenario
  • Combined energy system and LCA analyses of a 100% renewable scenario including hour balances of bio(syn)gas production, storage and exchange (additional to balancing and exchange of electricity)
  • Evaluation of electricity grid stabilisation with electric vehicles
  • Design of a policy and implementation strategy


  • Establishment of a dialogue with potential beneficiaries and dissemination of tools and methodologies on an on-going basis including contributions to the Danish Society of Engineers Climate Action plan 2050 (2009), Heat Plan Denmark (2008 and 2010), EnergyTown Frederikshavn and Long-term vision for Aalborg Municipality (2010), among others
  • 5 PhD projects
  • 17 book chapters/journal papers
  • 25 conference proceedings and presentations
  • Input to proceeding strategic research projects, among others the “Zero emission buildings” research centre project 
  • Analyses and report input to a national debate on export of wind power from the Danish energy system. “Danish Wind Power - Export and Costs” (2010)
