Loui Algren is an engineer in sustainable energy systems from DTU. He has been at Energinet.dk in the department of Energy Analyses for 3 years where he has worked with integrated energy systems scenarios and synergies between energy sectors in a socioeconomic perspective. Denmark is world leading in integration of wind energy with 42% in 2015. Since Denmark is continuing to deploy wind power integration with the heat, gas and transport sector is crucial in order to achieve an efficient green transition which could be a show case for other countries. Loui Algren has an increasing interest in new market designs for integration of distributed energy resources and he considers this one of the major challenges for the future integrated energy system.
