Optimal design of fuel-shift solutions in integrated heat and power systems




Greater Copenhagen area

“Fuel-shift” is recognized as one of the most promising technical solutions enabling integrated low carbon heat and power systems. Our previous research has shown fuel-shift could reduce district heating network losses by 35%, and it could reduce the peak boiler usage by as much as 48%. The figure below provides an overview of the system and our experimental setup.

The current fuel-shift design is strongly influenced by the industry standard. For example, Danish standard provides suggestion of tank size design according the number of inhabitants. Current standard clearly does not take into account of the different flexibility level coming with a different design. You will help us to understand this from a techno-economic perspective.

Your role:

·       Understanding the system operation and fuel-shift concept proposed in our research

·       Optimal sizing/sensitivity analysis for heat booster w.r.t. power rating, water storage tank size, inlet temperature of DH, and heat demand

·       Document your suggestion for the industry in view of the increasing need of flexibility with increasing wind penetration in the energy system.

Technical University of Denmark

For almost two centuries DTU, Technical University of Denmark, has been dedicated to fulfilling the vision of H.C. Ørsted – the father of electromagnetism – who founded the university in 1829 to develop and create value using the natural sciences and the technical sciences to benefit society.

Today, DTU is ranked as one of the foremost technical universities in Europe, continues to set new records in the number of publications, and persistently increases and develops our partnerships with industry, and assignments accomplished by DTU’s public sector consultancy.
