Explanation of Responses:

1. Constellation Energy Corporation ("Constellation") may be deemed to indirectly beneficially own the securities held directly by Constellation Energy Generation, LLC ("CEG") and reported herein because CEG is a wholly-owned subsidiary of Constellation, a publicly traded company listed on The Nasdaq Stock Market LLC. Constellation disclaims beneficial ownership of the securities reported herein except to the extent of its pecuniary interest therein, and the inclusion of those securities in this report shall not be deemed an admission of beneficial ownership thereby of any securities reported herein for purposes of Section 16 of the Securities Exchange Act of 1934, as amended, or otherwise.

2. Each Class A Unit of Net Power Operations LLC (f/k/a Rice Acquisition Holdings II LLC) (collectively, the "Opco Units"), a wholly-owned subsidiary of NET Power Inc. (the "Issuer"), held by CEG is redeemable at CEG's request in exchange for one share of Class A common stock of the Issuer or, at the Issuer's election, cash. Upon CEG's redemption of any Opco Units, an equal number of shares of Class B common stock of the Issuer ("Class B Common Stock") held by CEG will be canceled. The shares of Class B Common Stock carry no separate economic rights but vote together with the Opco Units.
