🚨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

🚨“While Germany aims to achieve climate neutrality by 2045, reducing CO2 emissions must be the primary step. #CDR measures, while important, cannot remove the large amount of CO2 emitted in 🇩🇪. It is assumed that CDR can only offset ~5–15% of current emissions.”
DETAILS🧵1/11
But how effective and efficient are the various possible #CDR measures? What are the hurdles to implementing them? What are the costs? How environmentally friendly are they?
2/11
The research team investigated these and other questions in its latest study in which it analyzed the feasibility of 14 #CDR measures that could be implemented in Germany. The measures include #DACCS & #BECCS as well as measures to increase carbon uptake by ecosystems.

Frontier – the advance market commitment aiming to accelerate the development of CDR technologies, announced that they are accepting applications for their fourth prepurchase programme to receive $500k each.
@ToucanProtocol announced a total of $250k in grant funding available to apps integrating CHAR: the world's first onchain carbon dioxide removal credit pool, and a building block for planet positive applications.
🚨 In a NEW study published today, researchers presented an analysis of the atmospheric sulfur budget using nine state-of-the-art global circulation models with interactive aerosol modules & sulfur chemistry.
In particular, "researchers showcase the burdens of the main sulfur species represented in these models (OCS, sulfate aerosols, and SO2), as well as their latitudinal and vertical distribution and seasonal variability. Emission and deposition fluxes were also discussed."
2/12
FINDINGS:
"Sulfate aerosol, carbonyl sulfide & SO2 behave very differently in the atm, providing insight into the modeled processes. OCS is almost chemically inert in troposphere & is primarily influenced by transport mechanisms but undergoes photolysis in stratosphere."
