Carbon capture onboard LNG-fueled vessels: A feasibility study

Worldwide, drastic reductions in greenhouse gas emissions are required to keep climate change to a more or less acceptable level. As of yet, the shipping industry has found no solution to this problem: it is expected that international shipping will be stuck with fossil fuels for the coming decades. A promising way to tackle the problem is to capture the CO2 from the ship’s exhaust gases and storing it onboard until the ship reaches a port where the CO2 can be unloaded. By combining carbon capture with LNG as a fuel, far-reaching heat integration is enabled, thus making the system very energy efficient, requiring no external heat. In this thesis the feasibility of onboard carbon capture is investigated for ships that use LNG as a fuel.
