Hawaii Gas

What Hawaii Gas does

Hawaii Gas (legally The Gas Company, LLC) is the only government-franchised, full-service gas utility in the state of Hawaii, manufacturing and distributing synthetic natural gas (SNG), renewable natural gas (RNG), liquefied petroleum gas (propane), and a hydrogen blend to residential, commercial, and industrial customers. Founded in 1904 as Honolulu Gas Company, the company operates a regulated utility business on Oahu under Hawaii Public Utilities Commission oversight, served by 1,100 miles of pipeline and a fleet of 60+ delivery and 150+ service vehicles. It also runs non-utility propane distribution across all six major Hawaiian islands through local branch offices in Honolulu, Hilo, Kailua-Kona, Kahului, Lihue, Kaunakakai, and Lanai City.

The company's core technology stack includes a synthetic natural gas plant in West O'ahu that has been in operation since 1974 and produces SNG from a petroleum co-product, an RNG facility at the City and County of Honolulu's Honouliuli Wastewater Treatment Plant that generates up to 800,000 therms per year, and a pipeline network that safely accommodates up to 15% hydrogen blending — the highest utility hydrogen blend of any US gas utility. The company is piloting advanced hydrogen transport technologies including the HydroPel nanocomposite surface treatment with Oceanit and the U.S. Department of Energy, and the e-LOHC™ liquid organic hydrogen carrier system with Ayrton Energy, with the latter scheduled for early 2026.

Hawaii Gas generates revenue through subscription-based, regulated utility rates (subject to PUC approval) on Oahu, recurring LPG/propane distribution to residential and commercial customers statewide, and RNG offtake tied to the Honouliuli facility. Commercial and industrial customers are served through an enterprise field-sales motion with energy consultation, solutions engineering, and 24/7 emergency service, while residential customers access account management through the MyAccount online portal. The company is owned by Argo Infrastructure Partners, LP, which completed its acquisition in July 2022. Its stated strategic objective is to support Hawaii's goal of 100% renewable electricity and statewide carbon neutrality by 2045 through RNG expansion, hydrogen-blending scale-up, and clean-energy partnerships.

Core offering

Hawaii Gas manufactures and distributes synthetic natural gas (SNG) from its West O'ahu plant, renewable natural gas (RNG) captured from the Honouliuli Wastewater Treatment Plant, and liquefied petroleum gas (propane) to residential, commercial, and industrial customers across Hawaii's six primary islands. The company also blends up to 15% zero-emissions hydrogen into its pipeline fuel — more than any other U.S. gas utility — delivering energy through 1,100 miles of pipeline on O'ahu and LPG distribution statewide under a state-issued utility franchise.

Product overview

Hawaii Gas is Hawaii's only franchised gas utility, operating as a vertically integrated energy company that manufactures and distributes multiple gas products. The core offering consists of synthetic natural gas (SNG) produced at its West Oahu plant, renewable natural gas (RNG) from biogas capture at the Honouliuli Wastewater Treatment Plant, liquefied petroleum gas (LPG/propane) distributed statewide, and hydrogen blending (up to 15%)—the highest utility hydrogen blend in the nation. Services are delivered to residential and commercial customers through the MyAccount online portal for account management and bill payment. The company serves approximately 70,000 customers statewide across all six primary Hawaiian islands through its 1,100-mile pipeline network on Oahu, supported by customer-facing programs like Hawaii Gas Rewards, the Good Energy Gift Program, and a comprehensive safety services division. Clean energy initiatives focus on decarbonization through RNG expansion, hydrogen transportation technology pilots, and partnerships for renewable energy projects.
