Abstract

This narrative review explores recent advancements in turquoise hydrogen production via methane pyrolysis in molten metals, a promising approach for low-carbon hydrogen generation that addresses the environmental challenges of traditional steam methane reforming (SMR). This technology uses molten metals to decompose methane into hydrogen and solid carbon, offering a pathway with a favorable life cycle assessment (LCA) compared to SMR. By integrating renewable energy sources, utilizing biomethane, and managing solid carbon byproducts, molten metals methane pyrolysis has the potential to meet stringent environmental goals. However, the technology remains in an early stage, with considerable challenges related to scalability, material durability at high temperatures, and efficient heat management. Industrial viability depends on advancements in reactor design, corrosion-resistant materials, and monitoring systems. While molten metal methane pyrolysis shows environmental promise, it is too early to determine its suitability as the preferred technology for large-scale turquoise hydrogen production. Ongoing research in reactor optimization, carbon byproduct handling, and renewable integration will be critical to fully realizing the potential of this technology, especially for deployment in natural gas-rich regions.
熔融金属甲烷热解可持续制氢研究进展
本文探讨了熔融金属中甲烷热解制氢的最新进展,这是一种有前途的低碳制氢方法,可以解决传统蒸汽甲烷重整(SMR)的环境挑战。该技术利用熔融金属将甲烷分解为氢和固体碳,与SMR相比,提供了一种具有良好生命周期评估(LCA)的途径。通过整合可再生能源、利用生物甲烷和管理固体碳副产品,熔融金属甲烷热解有可能满足严格的环境目标。然而,该技术仍处于早期阶段,在可扩展性、高温下材料耐久性和高效热管理方面存在相当大的挑战。工业可行性取决于反应堆设计、耐腐蚀材料和监测系统的进步。虽然熔融金属甲烷热解显示出环保前景,但要确定其是否适合作为大规模绿松石制氢的首选技术还为时过早。正在进行的反应器优化、碳副产品处理和可再生能源整合方面的研究对于充分发挥该技术的潜力至关重要,特别是在天然气富集地区的部署。
