What is Hydrogen

Hawaii Gas has a long history of manufacturing hydrogen in Hawaii.

Hydrogen is the simplest of all elements, and a very clean energy source. When burned with oxygen or used in a hydrogen fuel cell, its only byproduct is water.

In the 1970s, Hawaii Gas began producing and using hydrogen to convert naphtha, a by-product from the local oil refineries, for the manufacture of synthetic natural gas (SNG) in the Campbell Industrial Park, Kapolei, on the island of Oahu. To this day, approximately 12% of the gas in our pipeline on Oahu is hydrogen — this is the highest concentration of hydrogen reported by any gas utility in the U.S.

Hawaii Gas is actively pursuing opportunities to increase the availability and utilization of hydrogen in Hawaii. In the early 2000s, we partnered with General Motors on a pilot program to develop hydrogen for transportation. Hawaii Gas provided support and facilities for hydrogen powered cars during this pilot, and data gathered has helped us to better understand how hydrogen can become a future fuel for the state. Today, we are working closely with Hawaii Center for Advanced Transportation Technologies (HCATT), US Hybrid Corporation, and Hawaii Natural Energy Institute (HNEI) on innovative local hydrogen initiatives.

We believe in the potential for hydrogen to help Hawaii reach its renewable energy goals and will continue to work on cutting edge initiatives to boost adoption of hydrogen vehicles, fuel cells, gasification, steam renewable methane reforming and investments in hydrogen production and infrastructure.
