Gas hydrate within sediments below the ground holds enormous reserves of methane gas that is increasingly used as a transition fuel from current carbon based energy to a greener future. However, ongoing climate change and production of methane gas from hydrate can have a detrimental impact on slope stability and production infrastructure. Advanced physical and numerical modeling will provide detailed characterization of complex sediment-hydrate interactions under different environmental conditions. This will to enable techniques and technologies to be developed for the safe and efficient production of methane gas from hydrate while also allowing robust assessment of the risks associated with slope instability associated with production and ongoing climate change.

地下沉积物中的天然气水合物拥有巨大的甲烷气体储量，越来越多地用作从当前碳基能源到更绿色未来的过渡燃料。然而，持续的气候变化和从水合物中生产甲烷气体可能对边坡稳定性和生产基础设施产生不利影响。先进的物理和数值模拟将提供不同环境条件下复杂的沉积物-水合物相互作用的详细特征。这将使技术和工艺得以开发，以安全和有效地从水合物中生产甲烷气体，同时也使人们能够对与生产和持续气候变化有关的斜坡不稳定性的风险进行有力的评估。
