This paper introduces the feasibility study of a Dock to Dock (D2D) use case, combining aspects of route development and infrastructure definition, for the transport of goods in South West England and South Wales. The proposed system makes use of new, more flexible and environmentally friendly means of transport, such as electric Vertical Take-Off and Landing (eVTOL) aircraft and electric Autonomous Zero-Emission (eAZE) vessels. To meet the environmental targets set out for the transport sector, the use of alternative hydrogenbased fuels is investigated for air, surface and marine vehicles. Logistics, regulations and infrastructure required for the safe and efficient production and distribution of such low-emission energy vectors is also considered. Digital twin of the system is proposed to study its safety and viability, while the analysis of energy requirements is proposed to inform policy makers and define the necessary infrastructure to meet future emission-free transport energy needs.
