Carbon Negativity Estimates for Grassland Biomass

Richard McGehee
February, 2007


 
Abstract.   Tilman, Hill, and Lehman propose high-diversity biofuels to combine energy production with carbon sequestration, a process which saturates over time. Adding carbon capture and storage technology, however, expands their proposal fivefold and eliminates saturation, helping reverse the decades-long anthropogenic transfer of carbon from the lithosphere to the biosphere.
