Re: Acceleration Request for NextDecade Corporation

Registration Statement on Form S-3 (File No. 333-228914) 

Ladies and Gentlemen:

Pursuant to Rule 461 under the Securities Act of 1933, as amended, NextDecade Corporation hereby requests that the effective date for the Registration Statement referred to above be accelerated so that it will be declared effective at 4:00 p.m., Washington, D.C. time, on December 26, 2018, or as soon thereafter as is practicable.

It would be appreciated if, as soon as the Registration Statement is declared effective, you would so inform Sean Jones of K&L Gates LLP, our counsel, at (704) 331-7406. We appreciate your assistance in this matter.
