Decarbonization Plus Acquisition Corp

Decarbonization Plus Acquisition Corp, sponsored by Decarbonization Plus Acquisition Management — an affiliate of Riverstone Holdings — merged with hydrogen commercial vehicle maker Hyzon Motors in July 2021, resulting in the publicly traded company under ticker HYZN. The blank-check vehicle IPO'd in 2020, targeting the clean energy and zero-emission transportation sector. Hyzon subsequently faced an SEC investigation and accounting restatements that weighed heavily on the business. In March 2025, HYZN filed a Form 15-12G with the SEC, initiating the deregistration of its securities and terminating its Exchange Act reporting obligations, effectively marking the wind-down of the public company.
