Linde’s $50m pipeline network connects Linde’s Clear Lake and LaPorte, Texas, hydrogen plants to the Deer Park Refinery, a 50:50 joint venture of Shell and PMI Norteamerica, a wholly-owned subsidiary of Petroleos Mexicanos (Pemex).

The hydrogen to the Deer Park facility will be used primarily for the production of ultra-low sulfur diesel to meet new, cleaner fuel standards.

Linde is a major supplier of hydrogen utilities to the North American refining industry and is also a major supplier of syngas products, including hydrogen, for industries in the Houston Ship Channel.

Linde North America president Pat Murphy said that the company has had a long relationship with Shell involving supply of industrial gases and on-site plants.

"This project was a difficult venture, given the competitive environment and no existing pipeline infrastructure," Murphy said.
