Analysing the Performance of Ammonia Powertrains in the Marine Environment

This study develops system-level models of ammonia-fuelled powertrains that reflect the characteristics four oceangoing vessels to evaluate efficacy ammonia as an alternative fuel in marine environment. Relying on thermodynamics, heat transfer, and chemical engineering, adequately capture behaviour internal combustion engines, gas turbines, processing equipment, exhaust aftertreatment components. The performance each vessel is evaluated by comparing its maximum range cargo capacity a conventional vessel. Results indicate per unit output power, engines are more efficient, require less catalytic material, have lower auxiliary power requirements than turbines. Most merchant strong candidates for fuelling if operators can overcome losses between 4% 9%, assuming updated retain same also establishes naval likely adopt without significant redesigns. Ammonia sector compelling option detailed component design continues show concept practically feasible. present data help such feasibility studies propulsion technologies.
