HYDROGEN SUPPLY SYSTEM, RESERVING DEVICE, RESERVING METHOD, AND PROGRAM

To efficiently support replenishment with hydrogen fuel and provision thereof.SOLUTION: A hydrogen supply system comprises: a facility specification part which specifies fuel supply facilities present nearby a travel route of a vehicle reaching a destination; a calculation part which calculates an estimated remaining amount of hydrogen fuel at arrival time when the vehicle arrives at the fuel supply facilities on the basis of remaining amount information representing the remaining amount of hydrogen fuel transmitted from the vehicle; a determination part which determines whether the vehicle needs to be replenished with fuel on the basis of the estimated remaining amount; and a registration part which registers an estimated replenishment amount based on the estimated remaining amount and the arrival time as reservations for use of the fuel supply facilities when the determination part determines that the vehicle needs to be replenished with fuel.SELECTED DRAWING: Figure 6 【課題】水素燃料の補給および提供を効率よく行うことを支援すること。【解決手段】水素供給システムは、車両が目的地に至るまでの走行経路の周辺に存在する燃料供給施設を特定する施設特定部と、前記車両から送信される水素燃料の残量を示す残量情報に基づいて、前記車両が前記燃料供給施設に到達する到達時刻における水素燃料の推定残量を算出する算出部と、前記推定残量に基づいて、前記車両への燃料補給の要否を判定する判定部と、前記判定部によって燃料補給を要すると判定された場合、前記推定残量に基づく推定補給量と前記到達時刻とを前記燃料供給施設における利用予約として登録する登録部と、を備える。【選択図】図６
