Re: Forests: Carbon sequestration, biomass energy, or both? - New paper #carbonsequestration

How well do these numbers fit with your calculations (in your message below)


“Every year, plants convert 4,500 EJ of solar energy and  120 Giga Tonnes of carbon [= 439 Gt CO2] from the atmosphere into [ ~240 Gt of new] biomass – eight times as much as the global energy need.” ( , 2016).  That same document identified the global composition of annual biomass supply in 2012 to be 56 EJ of biomass energy [about 29 Gt of biomass], with an expected near- tripling to 150 EJ by 2035 [~85 Gt of biomass].


The above is from the WBA (World Bioenergy Association) in 2016.

Hi David, research I did in 2007 claimed these figures,  - "Approximately 100 billion tons of carbon circulates between the atmosphere and the approximately 750 billion ton reservoir in Land plants” .

Later I came across a claim that it was 110 billion tons, so I thought well, that’s in the ball park.


So that gives us a pretty good margin, - we don’t have to pyrolize every skerrick. 


Last I could bear to look we are throwing about 15 billion tons into the atmosphere  every  year, but of course not at this moment thanks to Coronavirus.


Nothing like getting back to Base Principles Eh.

Something that I have puzzled about 4 years is how much of the total carbon taken in by plants during a growing season is shed in there dying deciduous leaves? If one had a forest in which the Dead leaves were converted to biochar how much of a difference would that make in terms of permits permanent sequestration

If every farmer made a three or so hedge row deep of "hard working" (trees, or hemp, or bamboo...whatever) along side the usual food production area of land available, an Earthly "balance" might be achieved at each location of "carbon farming" participants.  A professional cooker outfit could cook the year's production for the farmer.   OR, the farmer would possibly choose to do kon-tiki or whatever for themselves.  But a cooker machine portable, may commence trade deals for those who choose.


But education has to happen.      I know that here in Canada a portable unit is now available. (Expensive) In the meanwhile, I focus on building products privately.  There are a gargantuan batch of opportunities existing, certainly if one considers "organic" building products.


I say this to get us out of the forest. (logistics and tfl [tree farm licence] owners really don't want us in their faces.) I say this too, to protect farm lands.  I say this to share with everyone a perhaps doable, shared opportunity.


The big picture regarding climate change translates to me, that farmers have the ball in their court.   And we all agree; "biochar could help save the world".   Starting at the ground; the sun needs greenery to shine upon, so, observations are what leads me to say what I share.
