🚨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

A new paper suggests detonating an absolutely gigantic nuclear bomb (1,600x bigger than Tsar Bomba) deep beneath the seabed to accelerate carbon removal (#CDR).
A thread on this bold climate proposal:🧵1/11
2/ Climate change is an existential threat, which is why some researchers explore extreme solutions. This one might be one of them.
The idea? Use a nuclear bomb to shatter massive amounts of basalt, speeding up Enhanced Rock Weathering (#ERW)—a natural carbon capture process.
3/ ERW works because rocks like basalt react with CO₂, locking it away in mineral form. Scientists have suggested that crushing basalt into fine particles accelerates this process. "But even when optimized, ERW is slow & limited in scale." That’s where the nuclear bomb comes in
Silvania, backed by Mercuria, teams up with Conservation International and The Nature Conservancy on the "Race to Belém" initiative, aiming to raise $1.5 billion to generate carbon credits for Amazon rainforest preservation.
🚨PAPER—The Arctic’s frozen ground, permafrost, holds massive reserves of ancient carbon. As the planet warms, this carbon faces a dangerous release into the atm, accelerating climate change. Could solar geoengineering (#SRM) help save it? The answer is complex.
DETAILS🧵 1/7
2/7 Permafrost is warming faster than the global average, poised to unleash C stored for millennia. This creates a feedback loop—warming leads to more C release, which leads to more warming. Simulations show SRM could limit global warming to 1.5°C & slow permafrost thaw. But...
3/7 This research revealed that, at 1.5°C warming, permafrost loss is reduced by about 50% & carbon loss by about 33% due to SRM, compared to a high-emissions future (SSP5-8.5). However, significant losses still occur, even with SRM. By 2300, the damage remains substantial.
