Description

​

The HySupply Shipping Analysis Tool is a Microsoft Excel Workbook developed to model the cost of shipping hydrogen (as liquid hydrogen (LH2) and hydrogen carriers (ammonia, methanol, methane (LNG) and LOHC (as toluene / methylcyclohexane (TOL/MCH)). Users input all relevant shipping costs and can either select a shipping route from list of pre-determined routes linking major Australian and global ports to those in Europe and Asia, or can define their own shipping route data, hence enabling users to cost shipping transport via any route. 

​

The tool includes a comprehensive range of costs designed to emulate a close to reality analysis for shipping transportation of hydrogen and hydrogen carriers (transport mediums). These costs include ship investment, storage investment, additional capital costs, labour, canal, port, maintenance, miscellaneous, insurance, storage operating costs, additional operating costs, fuel, carbon emissions and boil-off gas (BOG) costs. To best enable comparison between transport mediums the levelised cost of transport via shipping is calculated by adding the total annual costs and dividing by the annual total energy delivered. This levelised cost is presented per kilogram (kg) of hydrogen, per gigajoule (GJ) of transport medium and per tonne (t) of transport medium.

​

Total energy delivered is dependent on the storage capacity of the ship (in tonnes) and the number of trips made per year, which in turn is influenced by the ship speed, shipping route length, time spent docked at port and ship availability (days per year the ship is available for operation). Total annual costs are a summation of capital and operating costs. Annual capital costs were calculated using a capital recovery factor for the ship capital costs (outright cost of buying the ship). Annual operating costs were given through the addition of labour, canal use charges, port service charges, maintenance, miscellaneous, insurance, storage operating cost, fuel, carbon emissions and boil-off gas (BOG) costs. Users are also given the option to incorporate any other additional capital and operating costs into the model if required.
