This project aims at deployment of methods and tools for effective utilization of industrial waste heat as well as other low temperature heat sources to provide higher efficiency and higher level of operational flexibility of aggregated energy systems. The primary target is to analyze the possibilities of using the energy intensive industries such as metal, petrochemical and cement industry in the North Sea region, as dispatchable load for grid control, using various development and operational scenarios. This will be achieved by conducting techno-economic analysis of industrial waste heat utilization to provide added value by means of poly-generation options that could enable additional storage options and thereby operational flexibility. The results of this studies will provide guidelines for future utilization of dispatchable loads and the related waste heat/low temperature heat for grid control applications. The secondary objective of the project is to investigate the state-of-the-art heat recovery systems including utilization of waste heat as energy source for Carbon Capture and Storage (CCS) options for obtaining maximum efficiency.

The results of this project contribute to a deeper understanding of concepts enabling better utilization of industrial waste heat as well as other low-temperature heat sources to improve energy efficiency and mitigate emissions as well provision of flexibility options for the overall energy system. The project will also provide tools incorporating technical and economic methods for evaluation of different options.

The research work of the PhD candidate will focus on:

  1. Carrying out background research to improve and deepen understanding of the available waste heat recovery systems
  2. Identification and use of suitable open source tools/software.
  3. Developing, assessing and optimizing energy recovery systems through appropriate simulations, from both energy and real-time techno-economic analysis point of view.
  4. Collecting and utilizing experimental and simulated data in collaboration with international partners of the project to evaluate and validate the developed tools.
