Clean energy firm Hawaiii Gas is looking to replace most of its current fuel base with renewable natural gas.

According to Pacific Business News, the company, which is owned by US-based infrastructure specialist Macquarie Infrastructure Corporation, has issued a request for proposals to purchase raw biogas and, or, bio-methane, also referred to as renewable natural gas, in Hawaii or elsewhere.

Hawaii Gas is trying to figure out where it can get these sources from and at what price, according to the report.
