๐Ÿšจ๐Ÿ“NEW PAPER ๐Ÿ“๐Ÿšจ

Recent study present an analysis of โ€œthe gap between the CO2 storage required to meet net zero targets and the slow maturation of regional storage resources.โ€

#NetZero
#EuropeanGreenDeal
#CarbonDioxideStorage
#EnergyTransition

๐Ÿงต 1/12 ImageImage
Researchers estimate that โ€œEuropean storage rates need to boost 30-100x by 2030 to meet #NetZero by 2050. ๐Ÿ‡จ๐Ÿ‡ณ & North America face a similar challenge. The slow global progress of #CarbonStorage undermines the latest IPCC, IEA & EU transition pathways to net zero by 2050.โ€
2/12 Image
โ€œThese pathways imply a radically in teased demand for carbon capture and storage & #NegativeEmissionTechnologies (#NETs), contributing 500 of 700 megatonnes of #CarbonDioxideRemoval annually by 2050.โ€
3/12 Image
Here, scientists of this study investigate โ€œif sufficient #storage can be developed in time. China ๐Ÿ‡จ๐Ÿ‡ณ (30%), (15%) and Europe ๐Ÿ‡ช๐Ÿ‡บ(10%) dominate global #emissions.โ€

In this study, โ€œEurope was chosen as a data-rich exemplar.โ€ย 
4/12
โ€œAssuming #NetZero in 2050, researchers back-calculate the #storage required under 3๏ธโƒฃ scenarios of low, medium, and high #CCS demand.โ€
5/12
โ€œEven the low demand scenario requires 0.2 Gt of #storage by 2030, increasing to 1.3 Gt by 2050. The moderate & high demand scenarios require 5-8 Gt by 2050. The current #CarbonStorage rate in #Europe is 0.001 Gt/yr.โ€
6/12 Image
So, โ€œthere is a huge gap btw policy demand & #storage supply. Adaptation of existing #hydrocarbon tech has the potential to close this gap, with CCS for the entire EU requiring less than half the historic rate of HC exploration & development in UK North Sea from 1980-2010.โ€
7/12 Image
โ€œCounter to expectation, #storage cannot be delivered by exponential growth but requires an early & sustained investment of 30-50 boreholes per year starting before 2030 to build sufficient capacity,โ€ researchers affirmed.
8/12 Image
โ€œA 5-year lead-time to identify & mature prospects needs policy intervention before 2025. Continued policy deferral will lock Europe into a low CCS pathway that restricts the contribution of #NETs at a potential cost of โ‚ฌ100 billion for every gigatonne delayed beyond 2050.โ€
9/12 Image
According to this research, โ€œNorth America & China require similar policy intervention to close the gap on #CarbonStorage and #NetZero.โ€

๐ŸšจSoil food webs boost carbon retention in farmlands

A new study reveals that simply returning crop residues to fields can supercharge soil food webs, enabling microbes, nematodes & fungi to lock significantly more photosynthetic C into farmland soils.

Details๐Ÿงต1/8 #CarbonSink Image
2/ Researchers from the Institute of Applied Ecology, Chinese Academy of Sciences (CAS), used field trials and ยนยณC isotope tracing to map how carbon fixed by crops travels into soil and through the soil food web.
3/ FINDINGS:

Returning crop residues (stover) emerged as a key driver:

It increased particulate organic carbon (POC) by ~30.96% & mineral-associated organic carbon (MAOC) by ~11.39% compared with plots where stover was removed.

๐ŸšจNew research shows how integrating Direct Air Capture (#DAC) with urea production - paired with COโ‚‚ pricing can slash emissions, reach cost parity with fossil-based urea by 2050 & reshape global fertiliser markets through policies like the EU #CBAM.

DETAILS๐Ÿงต1/9 #CDR Image
2/ What DAC-urea is?

It's urea fertilizer made with COโ‚‚ pulled directly from the air instead of COโ‚‚ from fossil fuels.

Air-captured COโ‚‚ + green ammonia โ†’ urea.

Same fertilizer, but far lower climate impact. Image
3/Study presents a framework combining process modelling, prospective LCA & TEA to compare DAC-urea with conventional fossil-based urea today & under 2050 climate scenarios, including a cross-country assessment of Denmarkโ€™s clean electricity system & Egyptโ€™s more C-intensive grid Image

๐Ÿšจ The Royal Society has published a new briefing today finding that techniques to reflect a small portion of sunlight back into space (#SRM) could help lower global temperatures if deployed worldwide, but cannot replace emissions cuts or fully address climate impacts.

๐Ÿงต1/7 Image
2/ โž The report reviews solar radiation modification (#SRM) approaches, including stratospheric aerosol injection (#SAI) and marine cloud brightening (#MCB), outlining their potential to temporarily reduce warming and associated risks.
3/ โž It notes that SRM would only mask the effects of GHG emissions and would not address issues such as ocean acidification.

๐Ÿšจ๐ŸŒฒ New research reveals that even intact boreal forests, some of the planetโ€™s strongest natural carbon sinks, lose their ability to absorb COโ‚‚ as they age.

Hereโ€™s what the scientists found & why it matters for our climate models๐Ÿงต1/9 #CarbonSink #CarbonRemoval Image
2/ Boreal forests cover vast regions across Canada, Russia, and Scandinavia and store enormous amounts of carbon in trees and soil.

Theyโ€™re often seen as stable, long-term carbon sinks, but this study challenges that assumption with new global-scale data.
3/ Using seven global Net Ecosystem Productivity (NEP) datasets and a high-resolution forest age map, researchers tracked how C uptake changes as forests grow older.

They used a space-for-time substitution method, comparing forests of different ages to infer long-term trends. Image

๐ŸšจA major 6-country survey (N=5,310) finds Europeans support -ve emissions to meet climate goals, but strongly prefer nature-based solutions like afforestation over engineered options like Direct Air Capture. Trust hinges on benefits for nature & future generations.

๐Ÿงต1/10 #CDR Image
2/ When allocating how to tackle emissions, respondents clearly prioritized immediate mitigation:

โ€ข Renewables: 37.3%
โ€ข Behavior change: 24.0%
โ€ข Nuclear: 20.2%
โ€ข NETPs: 18.5%

โžก๏ธ This shows people support #CDR, but believe deep emissions cuts must come first. Image
3/ So which NETPs do they support most?

2 approaches were evaluated:
๐ŸŒฒAfforestation/Reforestation (AR)
๐ŸญDirect Air Capture + Carbon Storage (DACCS)

AR scored +1.91 vs DACCS +0.64

โžก๏ธ This means people are 4.36ร— more likely to support forests as the favored way to remove COโ‚‚. Image
