🚨REVIEW PAPER🚨 #Hydrogen, a green energy carrier, is one of the most promising energy sources. However, it is currently mainly produced from depleting #FossilFuels with high #carbon emissions, which has serious -ve effects on the economy and environment. #HyBECCS #ATT
🧵 1/6
To address this issue, sustainable hydrogen production from bio-energy with #carbon capture and #storage (#HyBECCS) is an ideal technology to reduce global carbon emissions while meeting energy demand. 2/6
So, a recent review presents an overview of "the latest progress in alkaline thermal treatment (#ATT) of #biomass for #hydrogen production with #carbon storage, mainly focusing on the technical characteristics & related challenges from an industrial application perspective." 3/6
Additionally, the roles of alkali and catalyst in the #ATT process are critically discussed in the review, and several aspects that have great influences on the ATT process are expounded, such as:
🔸biomass types
🔸reaction parameters
🔸reactors 4/6
Review concluded that "compared with WGS, MEC, SMR, #biomass dark fermentation & gasification, #ATT of biomass for #H2 production has the benefits of:
🔸wide range of feedstocks
🔸low energy consumption
🔸high purity of H2
🔸#NegativeCarbonEmission from entire LC of biomass 5/6

🧵0/21
Frontier signed $31.6M offtake with Hafslund Celsio to remove 100,000 tons of CO₂ (2029–2030)—via the first-ever carbon removal retrofit of a waste-to-energy plant at Celsio’s Oslo facility.
🚨 @UKRI_News & @NERCscience is investing £10 million in four NEW research projects, launching this month as part of a 5-year programme—Modelling Environmental Responses to Solar Radiation Management (#SRM)—to assess the risks, limitations & trade-offs of SRM.
DETAILS:🧵1/8
2/ Project 1: Holistic Risk Assessment of SRM
Led by @imperialcollege, @BristolUni, @UniversityLeeds & @UniofExeter
The team will develop a new framework combining Earth system modelling with social & political analysis to better assess risks & trade-offs of SRM—especially #SAI
3/ Project 2:Marine CLOUD Brightening
Led by Uni of Exeter, Leeds, Reading, Manchester & Oxford
MACLOUD will model how spraying sea salt to brighten marine clouds could influence weather patterns, climate & ecosystems—looking closely at how cloud behavior changes at diff scales
🚨🌋 A new UCLA-led study reveals surprising findings about the 2022 Hunga Tonga—Hunga Haʻapai underwater volcanic eruption. Despite fears it would push global temps past 1.5°C, it actually cooled the Southern Hemisphere by 0.1°C!
Here's why:🧵1/8
#SolarGeoengineering #Aerosols
2/ When Hunga Tonga erupted in January 2022, scientists expected the massive release of water vapor to trigger warming, but a key factor shifted: The eruption produced smaller sulfate aerosols that unexpectedly cooled the atmosphere!
3/ Traditionally, sulfate aerosols cool the Earth by reflecting sunlight, while water vapor warms it. The eruption's aerosols were 50% smaller than those from previous eruptions (like Pinatubo, 1991), which made them more efficient at cooling!

Stockholm Exergi announced its decision to build one of the world’s largest BECCS facilities, a $1.3B project set to remove ~800,000 tonnes of CO₂ annually and be operational by 2028.
Enhanced rock weathering startup @EionCarbon secured $33M carbon removal offtake deal with Frontier to remove 78,707 tons of CO₂ (2027–2030) by applying olivine on U.S. Midwest and South farmland.
🚨How do political affiliations shape attitudes toward #SolarGeoengineering?🚨
A conjoint experiment with 2,123 US voters finds that partisanship outweighs message framing—meaning who delivers the message matters more than what the message says.
DETAILS🧵1/9
2/ The discourse on SG as a climate solution is evolving, but public perceptions—especially in the polarized US landscape—remain underexplored. This study () examines how different narratives & partisan sources influence attitudes.nature.com/articles/s4416…
3/Researchers tested 3 SG narratives:
-Complementary: SG as an add-on to emissions cuts
-Substitutive: SG as a standalone climate solution
-Moral hazard: SG as a risky distraction
