At first, the idea of harvesting, harnessing, even burning our beloved biomass may seem counterintuitive, at least from a carbon removal perspective. Why not just leave biomass be?
Well, as we've heard so far this season, the carbon cycle is out of kilter. Even with our best efforts of restoration and enhancement, relying on forests and soils alone for the carbon removal we need may be too slow, too short, too unreliable. Just leaving biomass be can't redress the huge atmospheric imbalance caused by our CO2 emissions (any time soon, at least).
This is where biochar and BECCS come in. One has been in action for thousands of years, the other is the poster child of IPCC net zero models. And while different, both offer to do more with biomass, for the sake of carbon removal and more.
Can these really achieve carbon neutrality, let alone removal? Is there enough biomass out there? Are these the scalable, permanent and reliable silver bullets we've been dreaming of?! In this episode, Tom and Emily teach each other a thing or two about how to get the best from your biomass, for carbon drawdown's sake.
