Scene

application scenario

To reduce cost of hydrogen transportation and ensure the hydrogne supply security, on-site hydrogen refueling station is proposed by Ally. On-site hydrogen generator could be from methaol reforming, SMR, or electrolysis of renewable electricity.

According to the resources of raw materials for hydrogen production at the site of the hydrogen refueling station, hydrogen meeting requirement of PEM fuel cells shall be produced on-site. The product hydrogen is compressed to 20MPa for primary storage, and then pressurized to 45MPa or 90MPa, and then filled into fuel cell vehicles through the hydrogenation machine; At the same time, a 20MPa long tube trailer is set at the primary storage end to provide hydrogen to other hydrogen stations, which is especially suitable for establishing an integrated hydrogen production and refueling master station in the suburbs of the city, and setting up a hydrogen sub-station in the center of the city to form a regional hydrogen master-and-sub-station.

The on-site hydrogen refueling station is especially suitable for mining heavy trucks, logistics vehicles in logistics parks and special tourist lines.
