Farm to fleets: Manure helps Chicago startup build natural gas network

By Ally Marotti, Chicago Tribune.

Chicago startup AmpCNG launched at a farm in northwest Indiana that converted cow manure to renewable natural gas.

Nearly five years later, that manure from Fair Oaks Farm is still a core part of the West Loop-based startup’s business. But its reach has grown. It now owns and operates 19 compressed natural gas, or CNG, stations in eight states, fueling the increasing number of vehicles that operate on the resource.

“You can fuel from Chicago to Miami with the network we’ve got in place,” said Grant Zimmerman, who was named CEO of AmpCNG on Thursday, replacing Nate Laurell, now executive chairman of the board.
