Master thesis - CFD on carbon free combustion

Master thesis – CFD on carbon free combustion

In most part of the world, renewable energy sources are now cheaper than fossil and nuclear power generation. As they deliver energy intermittently, there is a growing demand for energy storage solutions. While batteries can address the challenge of daily fluctuations, they are prohibitively expensive for weekly to seasonal storage needs. Simply speaking, the longer the energy needs to be stored, the more important is the low cost for the storage container. Chemical bound energy in the form of liquified electro-fuels can provide that. Hydrogen is the simplest of electro-fuels, but in itself not very storage friendly, as both liquefaction and compression are energy intensive, and/or requires expensive storage containers. Converting hydrogen to ammonia solves that. However, ammonia is not convenient as a fuel, as the fuel bound nitrogen forms both the polluting nitrogen oxides, NO and NO2, as well as N2O which is a strong greenhouse gas. Furthermore, ammonia has a low flame speed which can make it hard to achieve stable combustion.

Ammonia can however be cracked back to hydrogen, either partly or fully. To which extent it needs to be cracked depends on the configuration of the burner. This thesis aims to use the full potential of CFD to investigate how the fuel should be injected into the combustor of a gas turbine, and how much cracking is needed. Focus here is to continue exploring the viability of the previously identified concepts.
