Decarbonization of heavy industries using solar energy via a hot gas heat transfer fluid or synthesized energy carriers

Mechanical Engineering Graduate Seminar

Abstract

The application of solar energy to high temperature industrial processes is considered to a potential pathways with strong potential to contribute to the decarbonizing of the ‘difficult to abate’ industrial sector.

However, to realize this potential it is necessary to overcome the challenges of integration of solar energy into complex industrial processes. Two potential pathways to achieve this could be through:

  1. The utilization of concentrated solar thermal energy (CST) to heat a high temperature heat transfer fluid (HTF), which is then used as a high temperature heat carrier in a down-stream industrial process; and
  2. The use of solar energy as an energy source to produce intermediate chemicals, as chemical energy carries, to be then used in the industrial processes.

Gases has been found as a potential suitable HTF, enabling temperatures of > 850 °C. Nevertheless, despite the potential, the challenges associated with heating a gas with CST energy has been identified as the biggest barrier to the implementation of this technology, which is mainly attributed to the poor heat transfer properties of gases. Hence, new technologies are needed to reduce the technical challenges associated with heating gases using CST. On the other hand, hydrogen peroxide (HP) is an oxidant that has been recently identified as an energy carrier, which can be produced from solar energy. New technologies are also emerging for the use of HP in heavy industries. This seminar will present novel ideas in solar gas receivers and a new concept for the use of HP in cement and lime production technologies.
