Sundrop selects contractor for central La. plant Sundrop selects contractor for central La. plant Advocate business staff report July 16, 2013 Comments Sundrop Fuels has selected an IHI Corp. subsidiary as the contractor for Sundrop’s natural gas to gasoline plant in Alexandria. IHI E&C International Corp. in Houston is performing the front-end engineering design for the combined commercial and demonstration plant that will have the capacity to produce about 60 million gallons of finished gasoline from natural gas. Sundrop Fuels is working to prove its proprietary gasification technology for making renewable “green gasoline” from woody biomass. Its success could lead to a series of renewable gasoline “megaplants,” each producing more than 200 million gallons of cellulosic biofuel annually. Once initial phases of its contract are completed, IHI E&C will do the detailed engineering, procurement, construction and completions for the commercial plant.
