NREL tests Greyrock’s Flare-to-Fuels

Engineers at the Energy Department's (DOE) National Renewable Energy Laboratory (NREL) have completed a life cycle assessment to determine the greenhouse gas reduction of Greyrock's Flare-to-Fuels™ process that converts flare gas into transportation fuels, primarily premium diesel fuel.

"Based on our analysis, diesel from Greyrock's Flare-to-Fuels system has the potential to reduce greenhouse gas emissions significantly when compared to petroleum derived diesel fuels," said Eric Tan, NREL Senior Engineer. "Associated gas is often produced in connection with the production of crude oil, and these gases are burned (or flared) due to lack of equipment and infrastructure to capture and process this gas and to deliver it to markets for beneficial use. New technical solutions are allowing the industry to conserve this wasted energy resource while reducing emissions such as CO2, methane and black soot created by burning these greenhouse gases."

"Greyrock appreciates the ongoing collaboration with NREL and the interest in our Flare-to-Fuels platform," said Dennis Schuetzle, Chief Technology Officer at Greyrock. Earlier this year, Greyrock announced its new system for the reduction or elimination of routine gas flaring. Using Greyrock's Direct Fuel Production technology, Flare-to-Fuels systems are designed to convert flare or vented gas into clean transportation fuels.

The World Bank estimates that approximately 140 billion m3 (approximately 5 trillion ft3) of natural gas is flared annually resulting in the emission of more than 300 million t of CO2 to the atmosphere. If this same amount of flared gas was converted to clean fuel, it would result in the production of more than 18 billion gal./y.
