In a recently published paper, researchers use โan 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
๐งต1/9
Using kelp (Laminaria japonica) as an example of seaweed, the present study โvalidates 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
The results showed that โthe #CarbonSequestration (full life cycle) of kelp in Ailian Bay was 97.73g C /m2/year.โ 3/9
โ#Biomass carbon accounts for approximately 86.15% of the total value (982.53 g C/m2/year) of carbon absorption source of #kelp in Ailian Bay, with the remaining 13.85% consisting of RDOC and sedimentary carbon.โ 4/9
โThe #CarbonFootprint of the kelp in Ailain Bay is -1146.8 tons of CO2 per year, and the negative value indicates that the #kelp in Ailian Bay can contribute 1146.8 tons of #CarbonSink per year.โ
5/9
Moreover, scientists in this study calculated the amount of #biomass carbon that was #sequestrated by seaweed production in China from 2010 to 2020.
6/9
โIf all seaweed #biomass carbon is permanently #sequestered the results of this study suggest that about 250,000 tons of CO2 could be fixed by Chinese seaweed during this decade, which could reach 0.2% of China's peak carbon.โ
7/9
Accordingly, the present research concludes that โthe mass production of #seaweed can be utilized as an efficient method to #sequestrate carbon and a feasible method for evaluating the effect of kelp farms on climate change.โ

@4401earth raised $37M Series A funding for its mineralisation tech which aims to eliminate CO2 permanently & at scale. The funding will enable 44.01 to continue to refine its tech, develop commercial-scale projects & expand its deployment globally.
@Climeworks has signed a multi-year contract with Zรผrcher Kantonalbank. The agreement aims to remove around 1,750 tons of COโ that complements the Swiss bank's net-zero strategy, which continues to focus on emissions reductions.

@1PointFive_ has entered into an agreement with Microsoft to sell 500,000 metric tons of CDR credits over 6 years to support Microsoftโs CDR strategy. The agreement is the largest single purchase of CDR credits enabled by Direct Air Capture to date.
Sydney startup Fugu Carbon has secured funding within the range of $1 million to $1.7 million for its solid direct-air carbon capture solution. It will allow Fugu to further develop and scale its team and operations.

@heirloomcarbon unveiled plans to deploy 2 facilities in Shreveport, Louisiana, capable of removing 320KtCO2 per year at scale. The first facility will remove 17KtCO2/yr, with the second scaling up to remove 100KtCO2/yr by 2026 & 2027, respectively.
Denmark is investing โฌ1.35B into biochar carbon removal and plans to subsidize biochar carbon removal by up to โฌ300/t. Additionally, Denmark has become the first country to introduce a โฌ100/t CO2 tax in agriculture.
