Hydrogen, as a light and abundant element, plays a key role in the development of clean energy and holds significant potential for replacing fossil fuels to reduce greenhouse gas emissions. This study aims to evaluate and compare blue and turquoise hydrogen as two primary options for low-carbon hydrogen production and to assess their potential in mitigating environmental impacts. Blue hydrogen production methods, including hydrogen generation from methane and steam combined with carbon capture, utilization, and storage (CCUS) units, and turquoise hydrogen production through methane pyrolysis and solid carbon generation, were examined. A comparative analysis of costs, efficiencies, and environmental challenges of both types of hydrogen was conducted. The findings indicate that turquoise hydrogen, through the production of solid carbon instead of greenhouse gases, represents a more sustainable and environmentally favorable option. Based on some data, for every kilogram of hydrogen produced, between 12 and 13.5 kilograms of greenhouse gases are released, whereas turquoise hydrogen production via methane pyrolysis results in zero direct carbon dioxide emissions. Moreover, the energy consumption for turquoise hydrogen production has been reported to be up to 30% lower than that of conventional blue hydrogen production methods, highlighting its advantage in terms of energy efficiency. In Iran, transitioning away from fossil fuel dependency toward blue and turquoise hydrogen production requires the development of infrastructure, advanced technologies, and comprehensive policymaking. This effort necessitates leveraging existing resources, fostering indigenous knowledge, and encouraging new investments. The present study emphasizes the importance of advancing technologies related to blue and turquoise hydrogen production and highlights the need for equipping and upgrading facilities to optimize the utilization of these clean energy resources.
