The Gas Company has been in business since 1904 and has a workforce of 300 professionals. It provides clean, reliable and energy-efficient gas to residential, business and government customers throughout the state of Hawaii — Oahu, Maui, Hawaii, Kauai, Molokai and Lanai. The Company owns and operates the only SNG manufacturing plant of its kind in the United States. The plant uses a catalytic process to convert the byproducts of petroleum refining into methane (chemically identical to natural gas) and hydrogen for distribution to its customers in metropolitan Honolulu. It supplies SNG through a 1,100-mile pipeline network, and supplies propane gas (LPG) statewide. TGC is developing technology to further reduce its carbon footprint by incorporating domestically produced, renewable alternatives to petroleum for gas supply in Hawaii.
