Operational Impact of Ammonia as Marine Fuel: A MILP model for an Ammonia-Powered Shipping Network

The consequences of climate change are becoming more and more visible. A significant cause of this is CO2 emissions; the shipping sector is responsible for 3% of global CO2 emissions. As a result, the Fourth IMO GHG Study 2020 presents pathways to reduce the GHG emission of the shipping industry by 50% by 2050. Recent IMO goals have overtaken...

Costs competitive large-scale green hydrogen production in North-Africa in 2030: How can a system that produces green hydrogen and ammonia be optimized to minimize the levelized cost and will this system be able to compete with fossil fuel based production in 2030?

The European Green Deal states that it wants to develop 40 GW of electrolyzer capacity by 2030 in North Africa to combat climate change. Using PV power as the primary energy source, a system is designed that can produce green hydrogen and ammonia to investigate how the location and the capacity of the components can be optimized to produce at...

Shipping Renewable Hydrogen Carriers: A study on the impact of shipping renewable hydrogen carriers and using those as a fuel on, the ship design, the different powertrain configurations, and the cost of transported hydrogen

Hydrogen enables renewable energy storage, and hydrogen carriers can allow easier transportation. This research was initiated to get more insight into transporting renewable hydrogen carriers (RHCs) by ship, which is one of the transportation options. The research was conducted in three steps. First, a system description with a literature study...

A Techno-Economic Evaluation of Green Ammonia

Up until now, ammonia has primarily served the fertilizer and chemical industry with limited regards to carbon emissions. The hydrogen within the ammonia molecule is commonly produced using fossil fuels; this process accounts for 1,2 % of the global CO2 emissions. Rather than using fossils fuels, electrolysis with renewable energy could be used...
