The production and sequestration of biochar (BC) may be described as a Pyrogenic Carbon Capture and Storage (PyCCS) carbon dioxide removal (CDR) solution. More specifically, it is a form of pre-combustion Carbon Capture and Storage (CCS), as distinct from the more common post-combustion CCS methods.
Biochar represents a fundamentally different approach to carbon dioxide reduction and removal. It involves the deliberate extraction of a solid, carbon-rich product from biomass prior to combustion, thereby preventing that carbon from being returned to the atmosphere.
When incorporated into soil, it may improve agricultural and horticultural soil performance. Importantly, biochar remains stable in soil for centuries, and possibly longer.
Accordingly, biochar use constitutes a viable means of long-term carbon sequestration, whilst also potentially enhancing plant growth under many conditions. Projects producing and sequestering biochar may be eligible to earn BidCarbon Removal Units (BRUs).
