Most of the discussion around Appalachian Store Hub has focused on ethane. That is entirely logical, as ethane is the raw material for ethane crackers – producing ethylene the largest volume chemical produced. Ethane storage would make the region more attractive to other companies beyond Shell and PTTGC for multi-billion dollar ethane cracker investments.

There is also the need to store the other NGLs such as propane or butane. Like ethane, these are the raw materials for petrochemical production. A propane dehydrogenation (PDH) plant would produce propylene the second largest volume ‘building block’ chemical. It is a multi-billion dollar investment. Propylene like ethylene is a building block chemical with many uses.

We can look at other petrochemical production centers like the US Gulf Coast or for what other products are stored and transported. These products are in addition to ethane, ethylene, propane, propylene and butane. They include methane, hydrogen, oxygen, nitrogen, carbon monoxide, methanol, and ammonia. These are all ‘building block’ large volume chemicals on which the industry constructs ever more complex and useful products.
