In a recently published paper, researchers use โ€œan LCA approach to calculate the Long-Lasting #CarbonSequestration (LLCS) of #seaweed, which can be understood as the difference between #CarbonFixation & released C throughout the life cycle of seaweed.โ€

๐Ÿงต1/9 ImageImage
Using kelp (Laminaria japonica) as an example of seaweed, the present study โ€œvalidates the procedure of calculating the LLCS of seaweed throughout its whole life cycle in Ailian Bay from nursery to processing into #biochar (fertilizer) as the final product.โ€
2/9 Image
The results showed that โ€œthe #CarbonSequestration (full life cycle) of kelp in Ailian Bay was 97.73g C /m2/year.โ€

๐ŸšจNEW PAPER๐Ÿšจ

"Utilization of biochar as a cementitious material aids in CO2 sequestration by impeding the release of C in the atm. So, a recent study reviewed the prospect of #biochar as a #cementitious material by evaluating its physical, mechanical & durability properties."๐Ÿงต ImageImage
This research suggested that "the physical properties of #biochar promote its use as an environmental control device."
A summary of the preparation and characterization of biochar is presented in a Fig. โฌ‡๏ธ
2/7 Image
According to the study, #pozzolan is a siliceous & aluminous material
that chemically reacts with Ca(OH)2 at room temp to form compounds having #cementitious attributes. So, some of the silica-rich biochars, like the ones derived from #RiceHusk have pozzolanic properties."

"International C markets are a very potent tool for mobilizing #CarbonDioxideRemoval in line with Paris Agreement ambitions to limit global warming to well below 2ยฐC. Yet, C market regulators have not systematically approached removals."

"The Kyoto mechanisms and the large #VoluntaryCarbonMarket standards have long focussed on biological removals without inherent storage permanence and only recently started to develop methodologies for removals with #geological storage, #mineralization or #biochar."

๐Ÿ“ "The N-doped #carbon material is one of the most efficient #adsorption materials in the field of carbon capture."ย So, in a recent study a series of N-doped #biochars were successfully prepared by a facile solvent-free method.

Details in a ๐Ÿงตbelow โฌ‡๏ธ

[1/7] Image
Among all N-doped biochars, "the #biochar prepared with corncob๐ŸŒฝ powder, K2CO3ย & urea at 800ยฐC showed highest #adsorption ability (5.69 mmol/g at 0ยฐC & 1 bar) & selectivity (38.24 at CO2/N2ย = 10/90).ย The biochar also showed excellent thermal stability & cycle performance."
2/7
"Notable, correlation analysis showed that ultra-micropores were the decisive factor for #CO2ย #adsorption at low temperatures; nevertheless, the effect of N-doping would gradually appear with the increase of adsorption temperature."

๐Ÿšจ PAPER ๐Ÿšจ

A viable & novel formula for a #CarbonNegative, environmentally friendly #concrete that is nearly as strong as regular concrete has been developed recently at Washington State University.

#Concrete
#Biochar
#CarbonSequestration

*Summary* in a๐Ÿงต below:
1/6 Image
๐Ÿงซ Researchers exemplify "a synergistic C-capture strategy, i.e., using #concrete washout water & #biochar together to achieve carbon-negative concrete."

"This strategy enabled the biochar to #capture 22.85 wt% air-borne CO2, which precipitated CaCO3 onto the biochar."
2/6 Image
๐Ÿ”ฌ"This carbon-negative cement paste consisted of 30 wt% CO2-weathered #biochar and 70 wt% portland limestone #cement, which achieved the 7-day and 28-day compressive strengths of 22.1 MPa and 27.6 MPa, respectively," microscopic investigation revealed.

Today we publish the 1st edition of the "State of Carbon Dioxide Removal" report, a global assessment of the current #StateofCDR, and the gap we need to close to achieve the Paris temperature goal.
Full reportโžก๏ธstateofcdr.org
An ongoing ๐Ÿงต
[1]
This report compiles a first estimate of the total CDR being deployed (2 GtCO2/yr).
Almost all comes from "conventional" CDR on land, via afforestation, reforestation & forest management.
"Novel" methods donโ€™t contribute much yet.
#StateofCDR
[2]
We provide a calculation of total gross CDR in #IPCC-assessed pathways to keep warming below 1.5C and 2C, including all methods. All pathways involve substantial cumulative CDR volumes (450-1100 GtCO2 by 2100) - in addition to immediate & deep emissions reductions

The #IPCC #AR6 WG3 report includes a comprehensive assessment of Carbon Dioxide Removal (CDR), its role in mitigation strategies and long-term pathways, but also a techno-economic assessment of ~10 CDR methods
An ongoing ๐Ÿงต
[1/n] Image
For Carbon Dioxide Removal, it's still early days in #climate policy, although there are already established methods (mainly forestry-related and soil carbon sequestration, not necessarily done to remove CO2)
In #AR6 reports, there aren't chapters dealing solely with CDR
[2/n]
There was quite some CDR coverage already in the #AR6 Special Reports on 1.5ยฐC (#SR15) and on land (#SRCCL). In WG I, CDR was mainly assessed in chapter 5 ('Biogeochemical Cycles'), and a bit in chapter 4
