项目摘要

The greenhouse gases produced by Canada's trucking and marine shipping industries can be reduced by using alternative fuels such as liquefied natural gas (LNG). LNG is a cryogenic fuel, so it must be carefully stored, transported, and dispensed to minimize the release of methane vapour to the environment. If LNG systems fail and fuel is spilled, environmental and safety consequences may result. Ship structural components may fail due to thermal stresses caused by the spilled LNG's extremely low temperature. Moreover, the resulting methane vapour has high climate impact and is flammable. To help develop LNG as a safe and clean alternative fuel for marine shipping and heavy-duty trucking, a deeper understanding of how LNG behaves in real industrial systems is required. The proposed research project will develop a suite of computer-based modelling tools in collaboration with Westport Fuel Systems, Fortis BC, BC Ferries, and the Port of Vancouver. The tools will be used to evaluate the behaviour of LNG during storage and transport in trucks and ships, to ensure the integrity and safety of ship structural components following LNG spills, and to predict the atmospheric dispersal of methane gas following venting or spill of LNG. Ultimately, the research will assist in safely transitioning Canada's trucking and marine shipping industries to lower-carbon fuels for significant carbon reductions and cost savings.

通过使用诸如液化天然气（LNG）之类的替代燃料，可以减少加拿大卡车运输和海洋运输行业生产的温室气体。液化天然气是一种低温燃料，因此必须仔细存储，运输和分配它，以最大程度地减少甲烷蒸气到环境中的释放。如果液化天然气系统故障并且燃料溢出，则可能会导致环境和安全后果。由于溢出的LNG极低温度引起的热应力，船舶结构成分可能失败。此外，由此产生的甲烷蒸气具有很高的气候影响，并且易燃。为了帮助开发液化天然气作为一种安全，干净的替代燃料，用于海上运输和重型卡车，需要更深入地了解在实际工业系统中的液化天然气行为。拟议的研究项目将与Westport Fuel Systems，Fortis BC，BC Ferries和Vancouver港一起开发一套基于计算机的建模工具。这些工具将用于评估卡车和船舶在卡车和运输过程中液化天然气的行为，以确保液化天然气溢出后的船舶结构组件的完整性和安全性，并预测液化天然气发泄或溢出后甲烷气体的大气分散体。最终，这项研究将有助于将加拿大的卡车运输和海洋运输行业安全过渡到低碳燃料，以大大降低碳和成本节省。
