Reducing energy-related methane emissions to meet the Global Methane Pledge

COP26的全球甲烷承诺和去年的欧盟甲烷战略表明，甲烷减排是我们这个时代的一个关键问题。甲烷是一种强有力的温室气体，占当今人为变暖的三分之一，但与二氧化碳相比，甲烷几乎没有受到关注。甲烷排放来自天然气供应链、沼气和农业等多个来源，但我们对排放和减排方案的理解很差。博士研究的主要目的是通过实地测量、环境建模和技术经济减排方案的结合，更好地了解与能源相关的甲烷排放。我们将使用包括定量光学气体成像在内的多种甲烷检测技术，对液化天然气燃料船、液化天然气设施、沼气设施和压缩机站等设施进行测量研究。下一阶段是进行生命周期环境评估，包括这些新数据，并确定可用于减少这些排放的技术和操作选项。将进行概率建模分析，以了解我们如何以及如何减少甲烷排放。

The Global Methane Pledge at COP26, and the EU's Methane Strategy last year, signals methane reduction as a critical issue of our time. Methane is a potent greenhouse gas, contributing a third of today's manmade warming, but has received little attention compared to CO2. Methane emissions come from several sources such as natural gas supply chains, biogas and agriculture but our understanding of emissions and mitigation options is poor.The main aim of the PhD research is to provide a better understanding of energy-related methane emissions via a combination of fieldwork measurement, environmental modelling and techno-economic mitigation optioneering. We will conduct measurement studies using several methane detection technologies including quantitative optical gas imaging, on facilities such as LNG-fuelled ships, LNG facilities, biogas facilities and compressor stations. The next stage is to conduct life cycle environmental assessments that include this new data and identify the technological and operational options available to mitigate these emissions. A probabilistic modelling analysis will be conducted to understand how, and by how much we can reduce methane emissions.
