Abstract
As Australia endeavours to decarbonize its energy sector, hydrogen emerges as a promising green energy carrier. This study conducts a techno-economic analysis comparing three hydrogen production methods: Green, Grey, and Blue Hydrogen, to evaluate their feasibility and economic viability. Through an in-depth assessment of the levelised cost of hydrogen (LCOH) and identifying key cost drivers, the study aims to discern an optimal production method by combining hydrogen production methods for a sustainable energy future. The findings reveal that a Hybrid Hydrogen production approach offers the lowest LCOH, presenting a cost-effective alternative, while Green Hydrogen has high environmental benefits, it requires higher capital investments. Conversely, the economically attractive Grey Hydrogen leads to significant emissions. There is high volatility of costs associated with Grey and Blue Hydrogen, due to their dependence on natural gas prices and Australian Carbon Credit Units (ACCUs). Addressing these calls for a strategic shift towards more stable, sustainable energy sources. The study identifies a balance between renewable fraction of 64.28% at a LCOH of $4.93/kg in a hybrid system—balancing economic and environmental objectives. Ultimately, the research provides strategic insights for transitioning to a hydrogen-centric energy landscape, highlighting the critical interplay between cost-efficiency, environmental stewardship, and market adaptability.
