Facility information

This facility produces:

  • About 2.7 billion cubic feet of high purity hydrogen from steam and natural gas each hour.

The Shell Puget Sound oil refinery uses these products in its processes. Air Liquide also sends its wastewater to the refinery for treatment. The refinery then sends the treated wastewater to Fidalgo Bay.
