Master thesis: carbon free combustion

About the Role

Location Sweden Oestergoetlands laen Finspang Company Siemens Energy AB Organization Gas Services Business Unit Distributed Full / Part time Full-time Experience Level Student (Not Yet Graduated)

Master thesis: C arbon free combustion

A Snapshot of Your Day

As the world strives to decarbonize the electricity sector, there is a growing demand for large scale energy storage. Being able to store and transport large quantities of energy is critical both to energy security as well as to handle fluctuating renewable power sources. Weaning of dependence on fossil fuels also broadens the supply choices, as renewable energy can be generated at any location where either solar or wind power is suitable.

A promising transport and storage vector is ammonia, as it liquefies at a reasonably low temperature, -33°C, at atmospheric pressure. The challenge in using ammonia as an energy storage lies in the difficulty in burning it cleanly and safely in power plants. Burning ammonia in innovative combustion systems, typically result in large amounts of nitrogen oxides, NOx, nitrous oxides, N2O, and potentially ammonia itself. However, recent research on this topic shows that there are strategies that appears promising. In this master thesis, we would like to use high fidelity computational fluid dynamics calculations, large eddy simulations, combined with finite rate chemistry modelling of the combustion process. The purpose is to find concepts that would work in a practical setting, given the operating conditions of a gas turbine.

How You’ll Make an Impact

  • Exploring novel combustion concepts on an early concept.
  • Deploy high fidelity CFD in a practical design process.
  • What You Bring 

  • Curious mind, eager to be a part of the energy transition
  • Scientific skills in the area of fluid flow and combustion
  • Master thesis: carbon free combustion
