1. Buyer Be There
For LNG: sell first, produce it later.
A industry joke is there three LNG permits you must have: DOE, FERC and Adam Smith Permit. The first two are easy to get because they authorize your LNG project to lose money in a environmentally sanctioned manner.
Note that a FERC permit alone cost $100 million dollars and the US Government is happy to accept that check in the spirit of American laissez faire without inquiring to the interest of would-be buyers. You have to actually be able to sell the LNG to make money. Financiers, banks, venture capitalist and private investors will not lend money or put capitol into a LNG project without buyers.
