The newly published article focuses on the physical & chemical aspects of #CO2#storage via liquid & solid chemical carriers & sorbents & gives an overview of the energetics around their use & options for their future development. #CarbonRemoval #CarbonStorage
🧵 1/7
Research pointed that "exciting opportunities for coupling #capture and medium to high maturity multi-year #storage technologies could support #CarbonRemoval in the coming decades." 2/7
Highlights of the analysis are:
🔸"The remarkable #storage capacity of oxalic acid & formic acid (CO2-density of 1857 kg m−3 & 1152 kg m−3, compared with condensed liquid CO2 at 993–1096 kg m−3, respectively)." 3/7
Cont'd...
🔸"The relative scalability and compatibility of carbonate salts for stationary storage with #DirectAirCapture, and the potential promise of multiple carriers for CO2 transportation." 4/7
So, results suggested that "solid sorbents do not achieve such ultra-high #storage capacities, but could improve storage over compressed gas tanks on a capacity and energetics basis." 5/7

Evero’s Ince biomass plant will be converted into the UK’s first BECCS site by 2029, capturing 217,000 t CO₂/year, processing 170,000 t waste wood, and powering 100,000+ homes.
🚨New research out on US public perceptions of #SolarGeoengineering:
More Americans oppose SRM research than support it, and 1 in 5 believe government-led atmospheric modification is already underway.
DETAILS🧵1/11
2/ Using 64 interviews, 10 focus groups, and a survey of 3,076 Americans, the study found strong initial rejection of solar radiation modification (#SRM) as a research priority.
Skepticism, fear of unintended consequences, and concern over “playing God” were dominant themes.
3/ Only 32.6% supported further SRM research. A notable 43.7% opposed it. For comparison, support was ~80% in similar studies from a decade ago. Enthusiastic support is now virtually nonexistent in qualitative responses.

Germany’s 2026 draft budget allocated €111 million for negative emissions in 2026 and a further €320 million in subsequent years. A new federal department has also been set up to focus on carbon removal.
🚨How does #SolarGeoengineering affect air pollution & public health?
New study using a cutting-edge Earth system model shows that #SAI has only modest effects on PM₂.₅ & ozone-related mortality & these impacts are mostly due to climate shifts, not aerosol deposition.🧵1/8
2/ Using CESM2-WACCM6 simulations across three scenarios (SSP2-4.5 baseline, ARISE-SAI-1.5, ARISE-SAI-1.0), the study quantifies global mortality attributable to ozone (O₃) & fine particulate matter (PM₂.₅) under future SAI deployment targeting 1.5°C and 1.0°C warming levels.
3/ Findings:
In the ARISE-SAI-1.5 scenario, maintaining global mean temp at 1.5°C above pre-industrial levels via SAI results in:
- 1.26% reduction in ozone-related mortality
- 0.86% increase in PM₂.₅-related mortality during 2060–2069, relative to SSP2-4.5.

Chestnut Carbon secured up to $210M in non-recourse financing, led by J.P. Morgan for its afforestation project, marking a first-of-its-kind deal in the US carbon removal space.
🚨Scientists have discovered a common soil bacterium, Bacillus megaterium, that can rapidly remove CO2 from the atmosphere by transforming it into solid limestone (calcium carbonate) within 24 hours, without creating toxic byproducts.

2/ Microbially induced calcite precipitation (MICP) is a technique where microbes precipitate CaCO₃, often used in eco-friendly building materials.
Most MICP uses urease to break down urea, which produces ammonium, a problematic byproduct.
3/ Bacillus megaterium is unique in a sense, it contains both urease and carbonic anhydrase (CA) enzymes. The latter allows it to fix CO₂ directly without needing urea.
But which pathway dominates? This study investigated that.
