Original abstract
In coal-dominated regions, hydrogen by-product from refineries can be used to replace coal as heating fuel. This can be a viable method for reducing CO2 emissions. Given that hydrogen injection into existing natural gas pipeline networks is an economical way to utilise this clean gas, this paper explores its benefits by studying its supply chain optimisation and analysing its reliability. First, a mixed-integer linear programming model is developed to minimise transport and dissatisfaction costs. Material balance, supply and transport of natural gas, operation of pipeline networks, and hydrogen injection are considered as constraints. The operating plans of a regional natural gas supply chain (NGSC), with and without hydrogen injection, are optimised. Then, three types of indicators – economic indices, coal and hydrogen as percentages of total energy consumption, and CO2 emissions – are applied to compare the performance of the NGSC in different situations. A case verifies the proposed model and shows the influence of utilising hydrogen in an NGSC. The optimal operating plans under one standard and two nonstandard conditions are calculated, and the reliability of the supply chain is analysed. Results illustrate that injecting hydrogen in the NGSC is beneficial in reducing CO2 emissions and operating costs.
