Natural Gas

GP has provided professional engineering design services for 25 liquefied natural gas (LNG) and liquid to compressed natural gas (LCNG) refueling stations in California, Arizona, and Texas. We also provided construction services at approximately one-third of these facilities. All civil, mechanical, and electrical professional design was performed with in-house staff. Of these stations, 22 have been successfully permitted and constructed and are currently in operation. The remaining three stations are currently in permitting or currently under construction.

For more information about GP's project experience in this area, please read about our LCNG project for Omnitrans.

Gaseous and Liquid Hydrogen

For the past 20 years, GP has been recognized by the United States Air Force, NASA and many commercial clients as the leading expert in cryogenic and high pressure system design, analysis, evaluation, and certification. GP maintains expertise in all types of pressure systems, and is familiar with most "non-standard" or unique pressure vessels and component construction methods. GP's engineering staff is experienced working with codes and standards on a daily basis to resolve technical issues. Many of GP's pressure system projects have been focused on hydrogen service.
