Hydrogen has an instrumental role to play in shaping the future of the UK's transport system. Huge reductions in 'Greenhouse Gas' (GHG) emissions may be achievable whilst providing a secure source of clean and sustainable fuel. Hydrogen transition has already begun but to strengthen and power the 'hydrogen economy' momentum in the UK, the development of the hydrogen infrastructure needs to make progress more quickly. There are many challenges associated with this due to the complexity at each node of Hydrogen Supply Chains (HSC), such as the number of processes to produce hydrogen. This raises the challenge to model HSCs, allowing analysis of various pathways and optimal configurations. This report aims firstly, to review the factors discussed in the literature on HSC and identify gaps or issues that require further debate with regards to introducing hydrogen in the transport system. Secondly, various HSC modelling techniques have been categorised according to mathematical methods used and the factors being considered. Studies in the literature have analysed hydrogen transport systems in terms of capital and operating costs of the infrastructure, and the cost of hydrogen, environmental implications and risk. A significant market share can be obtained by hydrogen in the near future with the minimisation of cost across the supply chain from production to end-use. Effective policies are required to speed up the process and increase the energy efficiency alongside mitigating GHGs and improving fuel security. Further developments in the mathematical optimisation models and technical breakthrough will enable the transition to a hydrogen economy take place with minimum disruption and issues.
