Greg and list:
1. Thanks for the alert. I hope you can report back on the
discussions at the two AAAS sessions you have identified below.
2. The AM session has this introduction: To augment these,
technologies exist that remove atmospheric carbon dioxide and can potentially
keep it out of the atmosphere — bioenergy with carbon capture and storage,
direct air capture, and biochar. These technologies have benefits and downsides
and vary drastically in predicted cost.
Greg: My quick review of the papers suggests they are all only/mostly
on the first (BECCS). Joe Romm three days ago wrote (at
http://thinkprogress.org/climate/2015/02/05/3619195/futuregen-clean-coal-project-dead/
)
on the cancellation of funding for Future Gen. (Follows similar CCS cutbacks
in the UK and Australia.)
a. I hope you can report on any dialog on how these funding cutbacks
will affect CDR projections for BECCS.
b. I wonder what the author of the words “vary drastically in
predicted cost” meant.
3. The biochar community has been woefully lacking in putting together
similar AAAS sessions. (I restrict my travel these days to places where
something is going for more than one session and/or someone else is paying the
bill.) But I did find that there are at least two student biochar posters
next week:
a. https://aaas.confex.com/aaas/2015/webprogram/Paper15882.html
“Utilizing Biochar to Mitigate Nitrate Leaching and Increase Crop Yield in
South Central WA”. One sentence saying: “Biochar is an effective additive
for combating excess nitrate leaching that will potentially appeal to
agribusiness due to the substantial increases in crop yields documented in this
study.”
b. https://aaas.confex.com/aaas/2015/webprogram/Paper15395.html
“Can No-Till Farming with Biochar Increase the Growth of Soybean Plants?” A
final sentence again:
“The results confirm that biochar with no-till farming produces the greatest
growth in soybean plants.”
4. Very unfortunately, the biochar community has been paying little attention
to the CDR side of biochar. I’d like to know whether the presenters of these
two posters have put anything in them on the CDR significance of their work?
Or only looking at biochar from the (non-competing) soil perspective?
