Enhancing the Feasibility and Sustainability of Circular Hydrogen Production Process in Malaysia via a Fundamental Process Integration Approach

Abstract

This thesis addresses sustainable hydrogen production in Malaysia, emphasising circular economy, local industrial, and resource integrations. Multi-objective mathematical optimisation model proposes a mix of hydrogen production pathways, favouring biomass-related technologies, particularly steam gasification. Life cycle assessment confirms their superior environmental performance, aligning with techno-economic analysis. Integrating hydrogen-to-electricity generation enhances self-sustainability but at increased costs, highlighting economic-environmental trade-off. Conventional methods remain vital for current demand. The study informs policymakers and researchers for effective hydrogen process design.
