(1) 报告题目:

Design and safety issues in hydrogen transport and storage: Case studies from the UK Humber Region

(2) 报告简介:

Hydrogen fuel switch in industrial and long-haul transportation systems is acknowledged to be essential to cut the cumulative carbon emissions of these sectors and reach net zero. However, large-scale hydrogen storage is challenging due to the difficult operating requirements such as extremely low temperatures of -253°C and up to 700 bar pressure for liquid and compressed hydrogen transport respectively. Hydrogen also has low density requiring at least 4 times conventional fuel storage capacities and has a high boil-off rate of up to 5% daily, when stored or transported in liquid phase, making their storage up to 3-4 times more expensive than the storage of other liquified gases. To mitigate these challenges, ammonia is widely considered a potential hydrogen ‘carrier’ candidate due to its high hydrogen storage capacity and its storage at moderate conditions (10 bar and 25°C); the Hydrogen Council predict up to 45% of hydrogen trade to be in the form of ammonia in the future. Therefore, most hydrogen storage and transport in the emerging hydrogen economy will be in the form of ammonia. Ammonia will be stored at scale never seen before and its large-scale storage raises significant safety concerns given its toxicity and volatility requiring comprehensive risk assessment. Using the example of UK Humber region, an industrial cluster expected to handle significant ammonia inventory and host ammonia-to-hydrogen plant to enable delivery of hydrogen to end user heavy industries in the region, this presentation will discuss consequence modelling which is a crucial starting point for industrial-scale ammonia risk assessments. This will cover integration of site-specific meteorological data and geospatial receptor analysis to evaluate offsite consequences based on Gaussian plume model. In addition, operational scenario for ammonia-to-hydrogen system -decentralised and centralised system- will be explored with considering its design and techno-economic indicators.
