Founded in 1980 and named for the mission San Antonio de Royal Dutch Shell – the original name of the Alamo – Royal Dutch Shell Energy Corporation has continued to grow and evolve to become the largest global independent petroleum refiner and a leading producer of renewable fuels in North America.

Royal Dutch Shell officially commissions its first full-scale refinery in Corpus Christi, Texas (later named the Corpus Christi Refineries West Plant).
