       Amendment No. 1 to Registration Statement on Form S-4

       Summary of the Proxy Statement/Prospectus
       Termination Rights of LanzaTech , page 34

   1.                                                   Please update your
disclosure here and on page 156 to clarify that, under the terms of the
                                                        Merger Agreement, AMCI
did not raise the necessary Proposed Additional Financing to
                                                        meet the Minimum
Closing Cash Condition by July 7, 2022 and, therefore, LanzaTech has
                                                        the outstanding right
to terminate the Business Combination. We note disclosure to this
                                                        effect on pages 97 and
117. If known, please also disclose whether LanzaTech specified
                                                        how much additional
time it would permit before exercising these termination rights.

revise the filing to
         confirm the conflicts of interest discussion highlights all material
interests in the
         transaction held by the sponsor and the AMCI officers and directors.
As currently drafted,
         you disclose only certain interests "among other things[.]" We note

Risk Factors
We and LanzaTech have identified material weaknesses in our internal control
over financial
reporting. . ., page 85

3.       We note your disclosure that you identified a    nondisclosure    that
represented a
            quantitative and qualitative    material weakness in your internal
control over financial
         reporting related to the accounting of certain fees owed to Evercore,
which Evercore
         waived in connection with its resignation. Please clarify the nature
of this material
         weakness and the amount of the    significant    error. Additionally,
where appropriate,
         please revise the "Background of the Business Combination" section on
page 109 and
         the "Resignations and Fee Waivers of the Advisors" section on page 118
to disclose:
             when the material weakness was discovered;
             when the material weakness was communicated to Evercore;
             whether the aggregate $13.05 million in fees owed to and waived by
Evercore
              accounted for this error.

4.       Please disclose when LanzaTech decided to restate its consolidated
financial statements
         for the years ended December 31, 2021 and 2020 and how such
restatements
         were considered in light of the pending Business Combination.
5.       Please explain how you came to enter into the Brookfield Framework
Agreement on
         October 2, 2022 and whether this was connected to your prior
relationships with either
         Goldman, Evercore, or Barclays. Relatedly, please disclose whether the
Brookfield
         Framework Agreement is the "third party capital" mentioned on page
117.
Resignations and Fee Waivers of the Advisors, page 118

6.       We note your response to comment 48, specifically that "[t]he Advisors
did not
         communicate to AMCI or LanzaTech the reasons leading to their
respective resignations
         or the waiver of their fees after doing substantially all of the work
to earn certain of their
         fees other than the work relating to the Proposed Additional
Financing." If true, please
         disclose that: (1) AMCI and LanzaTech did not seek out the reasons why
the Advisors
         were resigning and forfeiting their fees and; (2) the Advisors refused
to discuss the
         reasons for their resignations and forfeiture of fees with AMCI or
LanzaTech.

prepared by AMCI and
         LanzaTech and provided limited comments in the ordinary course; (2)
AMCI and

Note 5. Investments, page F-96

14.      We reference the disclosure on page F-81 that you determined your
licensing arrangement
         with LanzaJet should have been accounted for as a transaction with a
customer within the
         scope of Accounting Standards Codification 606     Revenue from
contracts with
         customers rather than akin to an operating lease under Accounting
Standards Codification
         842, Leases. Please revise to disclose the terms of the licensing
arrangement that you
         considered and how you concluded that accounting for the arrangement
under ASC 606 is
         appropriate.

15.      We note your response to comment 42 and re-issue in part. For each
exhibit
         that contains confidential information that has been redacted in
accordance with
         Regulation S-K Item 601(b), please include a prominent statement on
the first page of
         each redacted exhibit that certain identified information has been
excluded from the
         exhibit because it is both not material and is the type that you treat
as private or
         confidential.
General

16.      We note your response to our prior comments 13 and 32. Based on these
responses and
         your current disclosure, it appears to us that a majority of
LanzaTech's current commercial
         operations are located in China. For instance, it appears that the six
projects under
         development in Belgium, the United States, China, Japan, Canada, and
India are not
         material to LanzaTech   s current operations. In this regard, we also
note your response
         that the ArcelorMittal steel mill in Ghent, Belgium is currently under
construction. We

FirstName LastName
         also note the following disclosure on page 75: "While we are
headquartered in the United
         States and our executive team sits in Chicago, Illinois, we have
significant business
         operations in China. This includes a minority ownership stake in a
joint venture, several
         strategic investors located in China, including Sinopec, and a core
team of technical,
         business and administrative professionals at a LanzaTech office in
Shanghai,
         which support the ongoing operations and further growth of the
business in China. We
         license our technology in China, and our low carbon ethanol is
currently being produced
         at three commercial scale facilities operated by our partners using
our process technology,
         which, in addition to its use as fuel, is transported and processed
for use in consumer
         products. Meanwhile, several additional facilities are being
engineered and constructed."

         In light of the above, please either provide a detailed analysis,
discussing both quantitative
         and qualitative factors, supporting your determination that LanzaTech
does not have a
         majority of its current operations in China, or revise your
registration statement to address
         each of the comments from the Division of Corporation Finance   s
Sample Letter to China-
         Based Companies issued by the Staff in December 2021. To the extent
you do not believe
         a comment is applicable, please explain why such is the case in your
response letter.
17.      We note your response to comment 53. Please additionally provide us
with the February
         19, 2021 engagement letter between Barclays and LanzaTech in which
LanzaTech
         engaged Barclays to act as its financial advisor and capital markets
advisor in connection
         with the possible sale of LanzaTech   s business to a SPAC.
18.      With a view toward disclosure, please tell us whether your sponsor is,
is controlled by, has
         any members who are, or has substantial ties with, a non-U.S. person.
Please also tell us
         whether anyone or any entity associated with or otherwise involved in
the transaction, is,
         is controlled by, or has substantial ties with a non-U.S. person. If
so, please revise your
         filing to include risk factor disclosure that addresses how this fact
could impact your
         ability to complete your initial business combination. For instance,
discuss the risk to
         investors that you may not be able to complete an initial business
combination with a
         target company should the transaction be subject to review by a U.S.
government entity,
         such as the Committee on Foreign Investment in the United States
(CFIUS), or ultimately
         prohibited. Further, disclose that the time necessary for government
review of the
         transaction or a decision to prohibit the transaction could prevent
you from completing an
         initial business combination and require you to liquidate. Disclose
the consequences of
         liquidation to investors, such as the losses of the investment
opportunity in a target
         company, any price appreciation in the combined company, and the
warrants, which
         would expire worthless.
