Achieving negative emissions through oceanic sequestration of vegetation carbon as Black Pellets

Abstract Natural processes and human activities produce vast amounts of dead vegetation which return CO 2 to the atmosphere through decay combustion. If such could be converted into biocoal sequestered on ocean floor, it reduce accumulation atmospheric without involving sequestration in form . Given that raw is unsuitable for large-scale energy applications, a process was developed convert biocoal, termed Black Pellets, solves logistical conversion problems using power generation. Seemingly overlooked properties Pellets—higher density than seawater resistance microbial decay—may offer an environmentally safe way sequestering carbon sea floor. Sequestering by depositing as Pellets deep (oceanic biocoal—OSB) would means achieving long-lasting negative emissions. Sacrificing content deposited pellets require substituting from other sources. substitute lower-carbon natural gas or carbon-free sources, effects less compared nearly 60 100% reduction need geologic bioenergy capture storage (BECCS). confirmed research, OSB addition sparse toolbox emission technologies (NETs) give humankind more flexibility meeting goals Paris Agreement.
