Williams, N.; Seipp, C.; Brethomé, F.; Ma, Y.; Ivanov, A.; Bryantsev, V. et al. (2019): CO2 Capture via Crystalline Hydrogen-Bonded Bicarbonate Dimers. In: Chem. DOI: 10.1016/j.chempr.2018.12.025.

"Human activities in the last one and a half centuries have perturbed the natural carbon cycle, shifting massive amounts of carbon from the geosphere into the atmosphere and leading to climate change at an unprecedented pace. [...] Here, we demonstrate a promising approach to CO₂ capture based on crystallization of bicarbonate-water clusters with a simple guanidine compound. The CO₂ separation cycle involves a unique proton-transfer mechanism via the formation of a carbonic acid dimer, leading to efficient CO₂ release and quantitative regeneration of the guanidine compound and requiring significantly less energy than state-of-the-art carbon-capture technologies."

"The California campus, designed by Louis Kahn in the early 1960s, is one of the most celebrated examples of modernist architecture in the world. Its stark grandeur is as ambitious as the groundbreaking research taking place inside. [...] Now a group of them are tackling another life-threatening problem: climate change. They are setting out to do something that has never been done before, to create the “Ideal Plant” — one that will help curb global warming."

Miocic, J.; Gilfillan, S.; Frank, N.; Schroeder-Ritzrau, A.; Burnside, N.; Haszeldine, S. (2019): 420,000 year assessment of fault leakage rates shows geological carbon storage is secure. In: Scientific reports 9 (1), S. 769. DOI: 10.1038/s41598-018-36974-0.

"Carbon capture and storage (CCS) technology is routinely cited as a cost effective tool for climate change mitigation. CCS can directly reduce industrial CO₂ emissions and is essential for the retention of CO₂ extracted from the atmosphere. To be effective as a climate change mitigation tool, CO₂ must be securely retained for 10,000 years (10 ka) with a leakage rate of below 0.01% per year of the total amount of CO₂ injected. Migration of CO₂ back to the atmosphere via leakage through geological faults is a potential high impact risk to CO₂ storage integrity."
