Biogas

Hawaii Gas, the state’s sole natural gas utility, has been tapped by Honolulu authorities to buy biogas from a municipal wastewater treatment plant and turn it into pipeline-quality synthetic natural gas (SNG) for retail customers on Oahu.

Hawaii Gas has released a request for proposals (RFP) seeking supplies of renewable natural gas (RNG) in the form of raw biogas and/or bio-methane as part of its previously announced fuel diversification strategy, which includes containerized shipments of liquefied natural gas (LNG) (see Daily GPI,Oct. 30, 2014).

An Idaho renewable alternative energy technology firm announced Tuesday a successful gas quality test for its system of producing biogas from dairy manure, turning it into what the company claims is another form of pipeline-quality natural gas. Officials of Intrepid Technology and Resources, Inc. in Idaho Falls, ID, officials said the firm is now prepared to make its first commercial delivery of manure-to-gas supplies to the local utility, Intermountain Gas Co.
