Abstract: Systems and methods of greenhouse gas removal and subsea sequestration are described herein. Disclosed systems and methods include a direct air capture device capturing greenhouse gases from the atmosphere, a transport apparatus fluidly connected to the at least one direct air capture device, an underwater disposal well fluidly connected to the transport apparatus, and an underwater work apparatus operatively connected to the underwater disposal well. The transport apparatus transfers the greenhouse gases to the underwater disposal well, and the underwater disposal well injects the greenhouse gases into an underwater geologic formation. The greenhouse gases may be solidified as mineral deposits and permanently stored in the underwater geologic formation. Disclosed systems may include a loading system configured to be periodically connected to the transport apparatus. The loading system has a plurality of rotatable joint modules connected by independently actuatable joints.
