Hydrogen Supply Chain

Hydrogen is forecasted as an energy solution for the future thanks to its advantages of cleanliness, abundance and high energy conversion efficiency. The paper briefly introduces the hydrogen supply chain, hydrogen production technologies prevailing or expected in the future, as well as challenges that need to be addressed for a successful transition to a hydrogen-based economy.

Hydrogen will play a major role in the decarbonisation of the global economy. Energy companies are likely to extend interests in hydrogen exports and will need a credible hydrogen supply chain. Patent intensity, coupled with recent hydrogen production technology reviews and commercial activity by companies such as Kawasaki, provides support for forecasting a hydrogen supply chain that will include the following steps: Steam reforming of methane or coal, preferably methane, to produce hydrogen; hydrogen liquefaction (LH2) in preference to ammonia or liquid organic hydrogen carriers (LOHC) such as toluene (though this methodology has been trialled for Brunei produced hydrogen); shipping of LH2 to export markets; hydrogen gasification by end users. Given the 20 year lifecycle of patents, this forecast is anticipated to hold until 2030–40. The forecast does not exclude other technical options for hydrogen production and shipping but cost and technical risk will need to be minimised below the mature technologies of steam reforming and hydrogen liquefaction.

Low Carbon Energy

Hydrogen is recognized as a key element of future low-carbon energy systems. For proper integration, an adequate delivery infrastructure will be required, to be deployed in parallel to the electric grid and the gas network. This work adopts an optimization model to support the design of a future hydrogen delivery infrastructure, considering production, storage, and transport up to demand points. The model includes two production technologies, i.e., steam reforming with carbon capture and PV-fed electrolysis systems, and three transport modalities, i.e., pipelines, compressed hydrogen trucks, and liquid hydrogen trucks. This study compares a multi-modality formulation, in which the different transport technologies are simultaneously employed and their selection is optimized, with a mono-modality formulation, in which a single transport technology is considered. The assessment looks at the regional case study of Lombardy in Italy, considering a long-term scenario in which an extensive hydrogen supply chain is developed to supply hydrogen for clean mobility. Results show that the multi-modality infrastructure provides significant cost benefits, yielding an average cost of hydrogen that is up to 11% lower than a mono-modality configuration.
