Carbon Terrestrial Storage of Biomass

Background

The biggest driver of the climate crisis is that we took the coal out of the ground and burned it. What if we could reverse that process at world-changing scale? This novel approach to carbon removal uses the best process that exists for removing carbon from the air – trees; and enhances it. The biomass is actually returned underground– reverse mining! This locks the carbon safely away for hundreds or thousands of years.

Why did we choose this project?

Keeping global warming to 1.5C is going to require us to launch and scale activities that remove carbon from the air and lock it away for 100s of years. Billions of tonnes of it. Getting funding to these vital projects is one of the biggest things we can do to tackle the climate crisis.

How does it work?

The process starts with planting of up to 13 different coppicing (able to regrow after thinning and pruning) high biomass production native trees and shrubs adapted to low rainfall and different soil types. Those trees are then coppiced to harvest the biomass, which is then compacted and buried underground, cutting off all pathways to decomposition. This will see the carbon locked away for years, in fact indefinitely if the integrity of the burial sites is maintained. The trees regrow quickly so the process can be repeated, creating a rapid, direct carbon removal.

How do we know it's working?

One of the strengths of the EBS methodology is the detailed and robust monitoring program that will take place. Once live, a statistically valid analysis program will be conducted to build a robust database of CO2 captured in the biomass. The condition of the biomass sealed within the subterranean chambers will be monitored by an early warning system. Further, physical monitoring will be conducted via periodic samples analysed for carbon. The scientific projections are that between 0% and 3% of the stored carbon will ever be lost back to the atmosphere.
