Gas hydrates (GHs), crystalline compounds formed by gas molecules encased in water lattices, are increasingly recognized for their dual role as both a potential energy resource and a factor in climate change, making their study pivotal to advancing decarbonization efforts. This review highlights recent advancements in imaging technologies that have significantly enhanced our understanding of GH formation, dissociation, and stability, with a focus on their implications for accelerating decarbonization. Cutting-edge techniques such as X-ray computed tomography (XCT), magnetic resonance imaging (MRI), and scanning electron microscopy (SEM) are explored for their ability to provide high-resolution structural and compositional insights. Particular emphasis is placed on microfluidics technology, which has transformed the study of GHs by enabling real-time visualization of hydrate dynamics at the pore scale under controlled conditions. The integration of micromodels with optical imaging techniques to simulate natural geological environments and investigate gas–water–hydrate interactions is discussed, alongside the impact of variables like temperature, pressure, and salinity on hydrate behavior. Furthermore, the development of in situ and real-time monitoring systems is examined for their potential to unravel the dynamic processes governing GH systems. By consolidating these advancements and addressing existing challenges, this review underscores the critical role of innovative imaging methodologies in driving research that supports decarbonization strategies through improved understanding of GH systems.
