Clean Earth Acquisitions Corp. (NASDAQ:CLINW) operates as a blank check company whose primary business focuses on effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization, or similar business combination with one or more businesses in the clean energy ecosystem; its target sectors include carbon capture, hydrogen production, sustainable agriculture, and renewable energy technologies. Incorporated in 2021 and headquartered in Bee Cave, Texas, the company maintains no significant independent operations and seeks opportunities globally within the energy transition space. In December 2023, Clean Earth Acquisitions Corp. completed a reverse merger with Alternus Energy Group Plc, resulting in Alternus listing on Nasdaq under a rebranded entity, with Alternus owning approximately 64% of the combined company post-closing and Vincent Browne serving as CEO of the transatlantic clean energy independent power producer; the deal valued the combined entity at around $863 million initially, supported by shareholder approval and extensions to the termination date through May 2024. As of late 2025, CLINW trades minimally with indications of potential delisting, reflecting post-merger dynamics and limited ongoing activity as a standalone SPAC warrant.
