POWER OF ATTORNEY

I, Timothy J. Cesarek, hereby authorize and designate each of
E. Cabell Massey, L. Lynn Smull, Alisher Nurmat, and Ned Prusse,
signing singly, as my true and lawful attorney-in-fact to:

(1)	execute for and on my behalf, in my capacity
as an officer and/or director of Gevo, Inc.
and its affiliates (the "Company"), the Form
ID and Forms 3, 4 and 5 in accordance with
Section 16(a) of the Securities Exchange Act
of 1934, as amended (the "Exchange Act"), and
the rules and regulations promulgated
thereunder;

(2)	do and perform any and all acts for and on my
behalf which may be necessary or desirable to
complete and execute any such Form ID or Form
3, 4 or 5 and timely file such form with the
Securities and Exchange Commission, any stock
exchange or similar authority; and

(3)	take any other action of any type whatsoever
in connection with the foregoing which, in
the opinion of such attorney-in-fact, may be
to my benefit, in my best interest, or
legally required of me, it being understood
that the statements executed by such
attorney-in-fact on my behalf pursuant to
this Power of Attorney shall be in such form
and shall contain such terms and conditions
as such attorney-in-fact may approve in such
attorney-in-fact's discretion.

I hereby further grant to each such attorney-in-fact full
power and authority to do and perform any and every act and thing
whatsoever requisite, necessary, or proper to be done in the
exercise of any of the rights and powers herein granted, as fully
to all intents and purposes as I might or could do if personally
present, with full power of substitutes or revocation, hereby
ratifying and confirming all that such attorney-in-fact, or such
attorney-in-fact's substitute or substitutes, shall lawfully do or
cause to be done by virtue of this Power of Attorney and the
rights and powers herein granted.  I hereby acknowledge that the
foregoing attorneys-in-fact, in serving in such capacity at my
request, are not assuming, nor is the Company assuming, any of my
responsibilities to comply with Section 16 of the Exchange Act.

This Power of Attorney shall remain in full force and effect
until I am no longer required to file the Form ID or Forms 3, 4
and 5 with respect to my holdings of and transactions in
securities issued by the Company, unless earlier revoked by me in
a signed writing delivered to the foregoing attorneys-in-fact.

IN WITNESS WHEREOF, I have caused this Power of Attorney to
be duly executed as of this 14th day of August, 2023.
