Design and techno-economic feasibility study of a hydrogen-powered integrated energy system for cold ironing application [dataset] Open Access

The maritime sector contributes substantially to greenhouse gas emissions, with direct implications for climate change and air quality in port-adjacent communities. This study investigates a hydrogen-powered cold-ironing system for a major international port under variable shore-side power demand. A semi-empirical model integrating a proton exchange membrane electrolyser, a proton exchange membrane fuel cell, hydrogen storage, and battery storage was developed. Techno-economic analysis and multi-objective optimisation were conducted to evaluate the proposed system configurations. Without heat recovery, the hydrogen storage and battery hybrid configurations achieved levelised costs of 0.5172 $/kWh and 0.4969 $/kWh, with exergy efficiencies of 46.44% and 47.43%, respectively. Under the upper-bound heat-recovery case, the corresponding levelised costs were 0.4498 $/kWh and 0.4488 $/kWh, with exergy efficiencies of 47.62% and 46.18%. The preferred configuration also achieves a discounted payback period of 8 years at a 7% discount rate, suggesting potential under the stated modelling assumptions. The results provide a system-level assessment of the proposed configurations under the adopted demand, cost and modelling assumptions.
