Hawaiʻi Gas unveils first renewable natural gas facility at Honouliuli
HONOLULU (Dec. 12, 2018) – The City and County of Honolulu and Hawaiʻi Gas, the state’s only regulated gas utility, commenced operations at an innovative renewable natural gas (RNG) facility sited at the City’s Honouliuli Wastewater Treatment Plant in ‘Ewa Beach, following a blessing and dedication ceremony today. The facility, which converts sewage waste-derived biogas into pipeline quality RNG, will initially produce approximately 800,000 therms of energy per year for O‘ahu homes and businesses, though production is expected to grow as new homes and businesses are developed in the area.
“Climate change and the resulting rise in sea level is already having an impact on O‘ahu and is the most critical issue we face,” said Honolulu Mayor Kirk Caldwell. “The ability to capture biogas from our sewage is the type of innovative project that will help us reach our renewable energy goals sooner rather than later. I thank Hawai‘i Gas for partnering with us on this exciting initiative, which will help us meet our clean energy targets while also generating revenue for the city.”
“Renewable natural gas is clean, sustainable energy. An entirely local product, RNG produced from waste gas helps reduce Hawaiʻi’s dependence on imported oil,” noted Alicia Moy, president & CEO, Hawaiʻi Gas. “This RNG project is an important step toward Hawaiʻi’s clean energy goals. Through this project with the City and County of Honolulu, Hawai’i Gas is delivering even cleaner gas to our O‘ahu pipeline customers for cooking, water heating, clothes drying and outdoor torch lighting. The RNG produced at Honouliuli helps build resiliency and diversity of supply to meet Hawai‘i’s energy needs. RNG leverages existing infrastructure to deliver greener fuels to our customers while providing an incremental revenue source to the city.”
The RNG facility at Honouliuli is equivalent to eliminating the need for nearly 15,000 barrels of oil and reducing greenhouse gases by the equivalent amount produced by 400 cars annually. By selling the biogas to Hawaiʻi Gas, the City and County of Honolulu is expected to generate approximately $1.6 million of revenue per year.
“This RNG project is a win for everyone,” said Lori Kahikina, director of the City and County of Honolulu Department of Environmental Services. “It’s capturing energy that was not being utilized and using it for the benefit of our residents and our community.”
Hawaiʻi Gas was awarded the Honouliuli Wastewater Treatment Plant RNG contract from the City and County of Honolulu in July of 2016, and invested about $5 million in equipment and infrastructure to process the raw biogas and to connect the RNG facility to the company’s existing gas pipeline.
Hawaiʻi Gas is also pursuing other similar local partnership opportunities for RNG, as well as other suppliers of RNG; in September 2018, HG issued a request for proposals seeking suppliers who can provide up to 80,000 therms of raw biogas and/or bio-methane per day.
