Sustainable hydrogen supply chain development for low-carbon transportation in a fossil-based port region: A case study in a tourism hub

Abstract

This study combines an investigation of Kish Island's transition to sustainable energy and transportation with a focus on the integration of hydrogen port infrastructure, employing nonlinear optimization to chart the path forward. It emphasizes the pivotal role of such infrastructure in transitioning from traditional vehicles and gas-fired power, evaluating scenarios like a 30% reduction in fossil fuels and the implementation of carbon taxes to encourage a shift to electric and hydrogen-powered vehicles. Forecasts suggest an increase in electric vehicle adoption to 46% by 2023, with a goal of complete electrification by 2042, thereby transforming the energy landscape and reducing emissions. Key to this transition is a 25% government subsidy on hydrogen vehicles to enhance market competitiveness, alongside the strategic embedding of hydrogen infrastructure within sustainable tourism zones. This approach creates a synergistic model of energy, transport, and environmental stewardship, aiming to elevate regional prosperity and sustainability. The study extends its innovative perspective to include the exploration of methanol production, the development of carbon markets, and the advancement of Carbon Capture and Storage (CCS) technology, positioning the hydrogen port as a crucial element in Kish Island's sustainable development strategy.
