SCHEDULE 13D/A

Page 4 of 6 Pages

EXPLANATORY NOTE

Pursuant to Rule 13d-2 under the Act, this Amendment No. 1 to the Schedule 13D (“Amendment No. 1”) amends certain items of the Schedule 13D filed by the Reporting Persons with the SEC on January 2, 2024 (the “Original 13D” and, together with this Amendment No. 1, the “Schedule 13D”), relating to the Class A common stock, par value $0.0001 per share (the “Class A Common Stock”) of Global Gas Corporation, a Delaware corporation (the “Issuer” or the “Company”), whose principal executive offices are located at 99 Wall Street, Suite 436, New York, NY 10005. All capitalized terms contained herein but not otherwise defined shall have the meanings ascribed to such terms in the Original 13D.

Item 3.

Source and Amount of Funds or Other Consideration

Item 3 of the Schedule 13D is hereby amended and supplemented as follows:

On December 5, 2024, the Issuer and each of the Sponsor and Mr. Glatt amended and restated each of their respective Related Party Notes to, (i) fix the principal amount of each Related Party Note (as opposed to such Related Party Notes being able to be drawn in varying amounts) at the amount outstanding as of September 30, 2024; (ii) change the maturity date of such Related Party Note to March 31, 2025, extendable by written consent of the holder; (iii) include interest of 5% per annum on the unpaid principal balance of each Related Party Note, payable in kind and not cash; and (iv) include a conversion feature whereby the holder may elect to convert the principal and accrued interest of such Related Party Note into Class A Common Stock at $0.15 per share, representing the last sale price of the Class A Common Stock on the date of the amended and restated Related Party Note (the “Related Party Note Amendments”). Accordingly, the number of shares of Class A Common Stock into which each Related Party Note can be converted is subject to change as interest accrues on the Related Party Note. The Sponsor and Mr. Glatt did not pay any additional consideration for the Related Party Note Amendments.

The Related Party Notes remain subject to customary events of default, the occurrence of any of which would automatically trigger the unpaid principal and interest balance of the Related Party Notes and all other sums payable with regard to the applicable Related Party Note to become immediately due and payable.

The foregoing descriptions of the Related Party Note Amendments do not purport to be complete and are qualified in their entirety by the full text of the each of the Related Party Note Amendments, a copy of each of which is filed as an exhibit to this Schedule 13D and is incorporated by reference herein.

Also on December 5, 2024, Mr. Glatt was granted 200,000 fully-vested shares of Class A Common Stock under the Issuer’s 2023 Equity Incentive Plan for services provided.

Item 4.
