Hydrogen refuelling station (HRS) is an intricate system consisting typically of compression, storage, and dispensing subsystems. Thus, monitoring of HRSs has become a challenge in a real-time operation. Mass balance analysis of such a system consists of evaluating for a given timespan the amount of hydrogen received (produced or delivered on-site) and the amount of hydrogen dispensed to the vehicles. Previous work focused on off-line evaluation of hydrogen losses of HRSs with on-site hydrogen production. This article proposed a solution to holistically evaluate hydrogen mass balance and periodically evaluate hydrogen losses at HRSs in a continuous operation environment. We applied the Holistic Idle Periodic Evaluation method on real-time operational data of two HRSs with off-site hydrogen production and deployed the system for online monitoring of the hydrogen losses. The two stations were found to have hydrogen mass balance of 94.2% and 83.6% with an uncertainty of ± 5. 0 %. Our method can track normal and anomalous system operations in real time. It is applicable for HRSs with both off-site and on-site hydrogen production and only requires one mass flow meter used for metering hydrogen being dispensed to vehicles. • Developed a method to evaluate hydrogen losses at hydrogen refuelling stations. • Analysed mass balance of stations with real-time operational data streaming. • Inspected concurrent operations and hydrogen availability at the stations. • The mass balance of the two retail stations evaluated is 94.2% and 83.6%. • Holistic Idle Periodic Evaluation Method reaches an uncertainty of ± 5. 0 %.
