[Terrapreta] a braoder theory of torrefaction and TP

[Duane Pendergast]

Thanks Sean,

 

I would object and already have formally - if CO2 equivalent reduction
credits for burning the methane were issued for it. In the developing world
of CO2 emission reduction credits, that is already proposed and possibly
happening.  It is unlikely credits for charcoal in terra preta will develop
as long as such  schemes are place. It is a much more lucrative way to earn
credits thanks to the greater efficacy of methane as a greenhouse gas. Being
perverse myself, I did write an article to try and explain the nature of
some schemes. Here is the introduction and a link to it. Check section 3.3
on Landfill Gas


May 2006 - Kyoto and Beyond: Development of Sustainable Policy


Some solutions which are proposed to reduce greenhouse gas emissions will
turn out to be ineffective. Some will even counter efforts to reduce
emissions by setting up "perverse" incentives which could actually encourage
the release of carbon dioxide to the atmosphere. This paper
<http://www.computare.org/Support%20documents/Fora%20Input/CCC2006/Sustainab
le%20Paper%2006_05.htm> , discussed at greater length in the Fora Input
section of this website, provides some examples and argues in favor of
solutions that can be sustained over the long term. (DRP 06/09/12)

Hi Duane, Jim,

 

You've made a super good point here!  Methane-CH4 from buried wood would be
an absolutely important issue.  A volume Methane gas-CH4 has the same global
warming potential as 25 times that volume of CO2 over a 100 year period and
the same global warming potential as 72 time that volume of CO2 or 20 years.
As the buried wood decomposes it will release Methane.

 

Here is maybe an interesting idea, though.  Suppose wood is buried and kept
wet and warm under the subsoil.  Then, like a landfill, it is sealed from
below and it is integrated with pipes from above.  This "wood-fill" could be
then treated like a source of natural gas.  What would you think of that?
Of course, as you harvest the Methane, you would reduce the carbon storage
and the ground would eventually subside.

 

Regards,

 

SKB
