Electro-fuels (E-fuels) are a potential zero-carbon fuel option, that are able to reduce emissions from the marine sector. However, e-fuels still face several challenges, as currently, their production costs are high, and the implementation
of e-fuels in the marine sector is still in a research and development phase. Therefore, this study focuses on the impact that implementing an e-fuel has for both the vessel and vessel owner, from a techno-economic perspective. Since this research is performed at Heerema Marine Contractors (HMC), the focus is on large offshore construction vessels.
Through findings obtained from literature research and a case study, a general indication is obtained regarding the impact of implementing an e-fuel on a large offshore vessel. Several KPIs are defined to quantify and evaluate this impact by
comparing them to a fossil base case.
