Advancements in Key Imaging Techniques for Gas Hydrate Research to Accelerate Decarbonization Efforts Shanker Krishna, María Dolores Robustillo, Yu-Hao Bu, Guang-Jin Chen, Atousa Heydari, Chang-Yu Sun, Isaac Wilson, Jyoti Shanker Pandey Energy and Fuels, 2025 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.
Sustainable hydrate inhibition: Pectin and MEG synergy for deep-sea environments Ankur Singh, Shanker Krishna, Ajay Suri, Lavish Kumar Singh, Isaac Wilson Natural Gas Industry B, 2024 To ensure the continuous operation of the oil and gas industry, it is imperative to maintain an uninterrupted flow of oil and gas through pipelines and pay specific attention to preventing disruptions caused by hydrate blockages. Kinetic hydrate inhibitors (KHIs) have garnered considerable interest due to their capacity for effective hydrate prevention with minimal dosages typically ranging from 0.5 wt% to 2 wt%, guaranteeing both safety and efficiency. While some KHIs, such as amino acids and certain classes of ionic liquids, are known to be biodegradable, it is crucial to explore, develop, and thoroughly evaluate more natural and sustainable alternatives to these KHIs. This study investigated the potential of pectin as a biodegradable HI and examines its performance in synergism with monoethylene glycol (MEG). To assess its inhibitory performance, we conducted measurements of the induction time ( IT ) and hydrate nucleation temperature ( T 0 ) essential for hydrate formation under different conditions. The experimental outcomes indicated that pectin demonstrated slightly lower performance in comparison with commercial KHIs. However, its performance improved significantly when combined with a concentration of MEG. A blend of 0.25 wt% pectin and 2 wt% MEG offered an IT of 6.53 h, while poly(vinyl pyrrolidone) (PVP) and poly(vinyl caprolactam) (PVCap) at 0.25 wt% provided ITs of 4.9 h and 5.9 h, respectively. IT escalated from 2.13 h at 0 wt% MEG to 7.99 h at a MEG concentration of 5 wt%, while T 0 exhibited a notable decrease from 8.32 °C at 0 wt% MEG to 1.39 °C at 5 wt% MEG. The identified synergy between pectin and MEG in hydrate inhibition suggests substantial potential for advancing deep-sea hydrate risk management strategies in future research.
