Project Details


Power to fuel refers to the production of fuels using CO2, N2, H2O, and renewable electricity. In this case, the renewable electricity may be used in electrolyzers to produce hydrogen from pure water or capture CO2 from flue gases. The resulted hydrogen and carbon dioxide can be used to produce valuable fuels such as methanol and ammonia. As a result, green fuels can be generated using renewable electricity, water electrolysis, and CO2 capture technologies which results in substantially reducing current greenhouse gas emission and avoid the impacts of the climate change.
In this project, the production of green ammonia will be evaluated and investigated. According to the statistics, around 146 million tons of ammonia was produced in 2019 and it is estimated that the amount of ammonia production in the world will be increased to 1.2 billion tons in 2050. Currently, Haber-Bosch process is used to produce ammonia. However, this process is energy intensive and operates under the steady-state conditions and because of that it requires a stable energy source. Therefore, it is not compatible with intermittent renewable sources like solar, wind, etc. Hence, the existing Haber-Bosch process should be redesigned to reduce its energy consumption and make it more compatible with renewable energy sources. The PhD project aims at modeling the ammonia synthesis reactor with a more active catalyst to exploit energy more efficiently and avoid the high required temperatures (>400 ֯C) and pressures (>100 bar) in the current Haber-Bosch process. Moreover, in this project an integrated reactor will be evaluated and modeled in which ammonia synthesis and separation occur at the same temperature. In this case, the produced ammonia can be separated from unreacted gases by using in situ NH3 sorption which not only results in eliminating the need for recycling the reactants, but also contributes to higher ammonia conversion by intensifying the process and removing equilibrium limitations. Furthermore, the condensation unit needed in the Haber-Bosch process is not required. This PhD project also aims at modeling advanced materials i.e., MOFs for energy storage in the form of hydrogen to solve the problem of fluctuations in renewable energy.
Furthermore, this PhD project will also evaluate the methanol production using the CO2 captured from a cement plant when Cryogenic Carbon Capture (CCC) process and Amine Scrubbing process are used. In this case, the energy consumption, purity, and quality of the captured CO2 for methanol production as well as the capital costs and the operating costs for capturing the carbon dioxide with 90% efficiency using these two technologies are investigated and compared with each other.
