Rice Acquisition Corp. II, trading under the ticker RONI, was a blank-check company that completed its initial public offering in 2021 and was sponsored by Rice Acquisition Corp. II Sponsor, LLC, an affiliate of the Rice family's energy investment platform. The SPAC targeted the energy sector, ultimately announcing a business combination with NET Power Inc., a clean-energy technology company commercializing the Allam-Fetvedt Cycle, a natural gas power process designed to produce zero atmospheric emissions. The 10-Q filed on August 12, 2021, covers the SPAC's operating period ahead of that transaction. The de-SPAC merger subsequently closed, with NET Power now operating as a publicly traded clean-power technology company.
