The global shift towards a low-carbon economy highlights the significance of hydrogen as a versatile energy source with applications in transportation, power generation, and industrial processes. While steam methane reforming (SMR) remains the primary method for hydrogen production due to cost competitiveness, its high carbon footprint poses challenges in addressing climate change. Alternative production pathways like water electrolysis, methanol cracking, and ammonia decomposition offer cleaner and more sustainable options, although they face limitations such as high energy consumption and technological advancements. Utilizing industrial by-products for hydrogen production can help reduce CO2 emissions, showcasing the potential for innovative solutions. Life cycle assessments and cost evaluations are crucial tools in assessing the environmental and economic impacts of various hydrogen production technologies, guiding decision-making towards sustainable pathways. Studies comparing different production methods emphasize the importance of reducing carbon emissions and transitioning to renewable energy sources for hydrogen production. While challenges exist in the transition to cleaner hydrogen production technologies, research and development efforts continue to drive towards a more sustainable energy future.
