To authorize the Secretary of Energy to make price floor loans to certain low-carbon coal-to-liquid fuel projects.

Amends the Energy Policy Act of 2005 to authorize the Secretary of Energy to enter into agreements, in the form of price floor loans, with up to six low-carbon CTL projects (that convert coal to liquid or gaseous transportation fuels) to guarantee each project a minimum price for its output of liquid or gaseous transportation fuels in return for: (1) payment to the United States of the cost of such loan; or (2) at the borrower's election, a call option for the United States equivalent in value to such payment.

Prohibits any agreement for a price floor loan unless the Office of Management and Budget (OMB) determines that the loan cost is fully offset by either certain payments or by the value of a call option.
