A first exploration of potential fuels for the Dutch Maritime Sector that will allow the sector to achieve the energy transition goals of 2050. A first comparison on costs of the power plants and life time fuel is made. Including, accepting a mix of green and grey fuel sources. The output is of use for anyone in the sector interested in the variations of the fuels.

This paper presents the current status of additive manufacturing, also known as 3D-printing, and its relevance for the maritime construction sector. This technology radically changes supply chains, product designs and production in comparable industries, thanks to benefits such as on-demand localized production and form freedom. However, cost-effectiveness, gaps in knowledge, high technology variance and lack of standardization limit adaptation within the maritime construction sector. Especially for large scale additive manufacturing research gaps exist in the structural area. Models for analysis of design and production are also needed to clarify the business case.
