Intended learning outcomes

After completing the course, students should be able to:

  • In detail describe the technical concept of cogeneration of multiple energy services with flexible fuel input, specifically with regards to
  • Characteristis of various energy converters, and their suitability for different system configurations.
  • Efficiency as compared to stand-alone production.
  • Environmental as well as economical performance.
  • consideration of the distribution in time of energy supply and demand of energy services.
  • Describe and carry out engineering design of smart buffers (batteries, hot and cold thermal energy storage, pure water reservoirs, etc)
  • Describe and carry out engineering design of functional control strategies for integrated Polygeneration systems.
  • Describe how small-scale Polygeneration systems can be operated if connected to a grid vs. being stand-alone, where the grid can be a classic national grid or a grid with distributed power generation.
  • Carry out advanced thermoeconomic optimizations for design of technically robust, and environmentally and economically sound polygeneration of energy services, as applied to practial need in various situations (e.g. industrial processes, the built environment and transportation)

Course main content

In the Polygeneration course, cogeneration of multiple energy services (heat, power, cold, pure water…) using flexible fuel input to allow for a sustainable energy mix will be in focus. The following sub-topics will be covered:

- Cogeneration;

- Control principles and strategies;

- The integration of smart buffers: batteries, thermal energy storage, pure water reservoirs, etc; and

- Thermoeconomic optimization of polygeneration systems.

Thus, the course aims at integrating those engineering skills previously aquired as applied to energy efficient energy conversion pathways -- Polygeneration.
