GreenHunter Energy Turns Houston Waste Oil Storage Site Into Renewable Fuels Campus

HOUSTON, May 22 /PRNewswire-FirstCall/ -- GreenHunter Energy opens the taps on the nation's single largest biodiesel refinery to date on Monday, June 2, at 10 a.m. The facility will produce 105 million gallons of "white-water" B100 biodiesel per year.

The converted waste-oil refinery on the Houston Ship Channel gives GreenHunter's renewable fuels campus direct deepwater access and the ability to transport products via barge, rail, and truck. Generators at the site will provide enough electricity for GreenHunter to sell unneeded power back to the grid. GreenHunter's campus also includes basic terminal operations and 700,000 barrels of storage capacity for feedstock management.

By producing biodiesel from multiple feedstocks, including non-edible sources such as tallow and jatropha, GreenHunter offers practical solutions to the ongoing "food versus fuels" debate.
