Natural Gas to Ethanol

Now here is a form of ethanol production I have no problem with.  Dallas TX based Celanese says it has a process to make ethanol relatively cheaply from natural gas.  

However, because the ethanol is produced from a fossil fuel, it doesn't qualify as a renewable fuel, and therefore can't be used to satisfy the renewable fuel mandates that are driving corn based ethanol.  So unless the law is changed, corn ethanol will continue to drive up food prices and eat tax money.
