Can you join the dots?
I believe there are now 3 key areas of research for safe, affordable, extremely useful and permanent Carbon removal:
Learning Issues:
Can random reflectance (Ro) of biochar be used as an indicator of C stability/permanence of organic C removal for long-term C sequestration, using the 'inertinite' benchmark, for Mean Residence Time (MRT)/half life predictions?
What is the relationship between Phytoliths and random reflectance (Ro) in biochar?
Here's a research algorithm to get the party started:
-plant Si content eg.rice husk, bamboo, switchgrass->plant phytoliths->plant biochar->random reflectance of biochar >2%->Inertinite for 100 million years+
All we have to do is phase out and switch off fossil or C removal seems to be a waste of time - apart from all the materials that can be made with biochar, so, why not do it anyway as eventually the Gov will follow? Many more friends will be made for future green business investment with a C removal agenda than selling C drugs of dependency for climate heating acceleration. THE most conservative position is the fabled 'Precautionary Principle' with loads of science to back up the position. Indeed, the number of publications on biochar research is increasing exponentially year after year.
