POWER OF ATTORNEY
FOR SECTION 16 REPORTING OBLIGATIONS

KNOW ALL BY THESE PRESENTS, that the undersigned, Diana Sands,
hereby makes, constitutes and appoints each
of Matthew Schatzman, Chief Executive Officer, Brent Wahl, Chief
Financial Officer, and Vera de Gyarfas, General Counsel, of
NextDecade Corporation, a Delaware corporation, or any successor
thereto (the "Company"), as the undersigned's true and lawful
attorney-in-fact, with full power and authority as hereinafter
described on behalf of and in the name, place and stead of the
undersigned to:
   1) prepare, execute in the undersigned's name and on the
undersigned's behalf and submit to the U.S. Securities and
Exchange Commission (the "SEC") a Form ID, including amendments
thereto, and any other documents necessary or appropriate to
obtain codes and passwords enabling the undersigned to make
electronic filings with the SEC of reports required by Section
16(a) of the Securities Exchange Act of 1934 (as amended, the
"Exchange Act") or any rule or regulation thereunder;
   2) prepare, execute, acknowledge, deliver and file Forms 3, 4,
and 5 (including any amendments thereto) with respect to the
securities of the Company, with the SEC, any national securities
exchange and the Company, as considered necessary or advisable
under Section 16(a) of the Exchange Act of 1934 and the rules and
regulations promulgated thereunder;
   3) seek or obtain, as the undersigned's representative and on
the undersigned's behalf, information of transactions in the
Company's securities from any third party, including brokers,
employee benefit plan administrators and trustees, and the
undersigned hereby authorizes any such person to release any such
information to the undersigned and approves and ratifies any such
release of information; and
   4) perform any and all other acts which in the discretion of
such attorneys-in-fact are necessary or desirable for and on
behalf of the undersigned in connection with the foregoing.

The undersigned acknowledges that:
   1) this Power of Attorney authorizes, but does not require,
such attorneys-in-fact to act in their discretion on information
provided to such attorney-in-fact without independent
verification of such information;
   2) any documents prepared and/or executed by such attorneys-
in-fact on behalf of the undersigned pursuant to this Power of
Attorney will be in such form and will contain such information
and disclosure as such attorneys-in-fact, in his or her
discretion, deems necessary or desirable;
   3) this Power of Attorney does not relieve the undersigned
from responsibility for compliance with the undersigned's
obligations under the Exchange Act, including without limitation
the reporting requirements under Section 16 of the Exchange Act;
and
   4) neither the Company nor such attorneys-in-fact assumes any
liability for the undersigned's responsibility or failure to
comply with the requirements of the Exchange Act, including
without limitation for profit disgorgement under Section 16(b) of
the Exchange Act.

The undersigned hereby ratifies all that such attorneys-in-fact,
for and on behalf of the undersigned, shall lawfully do or cause
to be done by virtue of this Power of Attorney.

This Power of Attorney shall remain in full force and effect
until the undersigned is no longer required to file Forms 3, 4
and 5 with respect to the undersigned's holdings of and
transactions in securities issued by the Company, unless earlier
revoked by the undersigned in a signed writing delivered to the
foregoing attorneys-in-fact.

IN WITNESS WHEREOF, the undersigned has caused this Power of
Attorney to be executed as of this 7th day of August, 2025.
