A new life cycle assessment (LCA) model software has been developed by DTU Environment, to facilitate detailed LCA of energy technologies. The model, EASETECH Energy, is dedicated to the specific technologies needed to assess energy production and energy systems and provides an unprecedented flexibility with respect to LCA modeling of these technologies. To illustrate the functionality of the model, preliminary results from a LCA of the Danish power system in 2010 as well as two future scenarios for 2030 are presented. In addition to providing a general overview of the environmental profile of a renewable based power system, specific focus is placed on the typical challenges encountered when performing an LCA of a power system. Further, the key characteristics of EASETECH Energy that can expedite the set-up of multiple scenarios and enhance transparency in the modelling are explained.
