Mašek, O.; et al. (2019): Potassium doping increases biochar carbon sequestration potential by 45%, facilitating decoupling of carbon sequestration from soil improvement

Mašek, O.; Buss, W.; Brownsort, P.; Rovere, M.; Tagliaferro, A.; Zhao, L. et al. (2019): Potassium doping increases biochar carbon sequestration potential by 45%, facilitating decoupling of carbon sequestration from soil improvement. In: Scientific reports 9 (1), S. 5514. DOI: 10.1038/s41598-019-41953-0.

"Negative emissions technologies offer an important tool to limit the global warming to <2 °C. Biochar is one of only a few such technologies, and the one at highest technology readiness level. Here we show that potassium as a low-concentration additive in biochar production can increase biochar’s carbon sequestration potential; by up to 45% in this study."

Moderndiplomacy: The Existential Crisis of Global Warming and Carbon Capture

"Direct air carbon capture and storage (DACCS) is an enticing prospect until one examines the costs.  Scientific scenarios project DACCS capacity to remove 10-15 billion tons of CO2 per year by century’s end.  Optimists up it to 35-40 billion tons solving the CO2 problem in one fell swoop.  Not so, say those who have examined costs."

MIT Technology Review: Startups looking to suck CO2 from the air are suddenly luring big bucks

"A small band of scientists have been trying to pluck carbon dioxide out of the air for years, despite the deep skepticism of their peers. But the space has suddenly gotten pretty popular."

Project: Project Vesta

"Project Vesta is a project to remove carbon dioxide (CO2) from the atmosphere and oceans by accelerating the weathering of a type of rock called olivine. When olivine interacts with water and the CO2 dissolved in it, a chemical reaction (called weathering) occurs that creates a bicarbonate solution that marine animals like corals use in their shells. The CO2 remains locked in that form and eventually settles as sediment or turns to limestone rock on the sea floor."

Dittmeyer, R.; et al. (2019): Crowd oil not crude oil

Dittmeyer, R.; Klumpp, M.; Kant, P.; Ozin, G. (2019): Crowd oil not crude oil. In: Nat Comms 10 (1), S. 1818. DOI: 10.1038/s41467-019-09685-x.

"Climate change represents an existential, global threat to humanity, yet its delocalized nature complicates climate action. Here, the authors propose retrofitting air conditioning units as integrated, scalable, and renewable-powered devices capable of decentralized CO2 conversion and energy democratization."

Volans & Nori: Hot to Tell the Whole Carbon Story (Video)

"We know that carbon removal is key to delivering on the net-zero climate target proposed by the IPCC report. The private sector has an untapped potential to drive carbon removal. This is the fourth installment from Nori and Volans' "New Carbon Economy" webinar series."

Yahoo Finance: CO2 Solutions Successfully Completes Commissioning of it First Commercial Carbon Capture Unit

"CO2 Solutions Inc. (the "Corporation") (CST.V) is pleased to report that, after only two weeks, it has successfully completed the commissioning of its first commercial carbon capture unit. The project, with Fibrek General Partnership, a subsidiary of Resolute Forest Products Inc. (RFP.TO) (RFP), and Serres Toundra Inc., involved the deployment of a 30-tonne per day (tpd) CO2 capture unit (the "Unit") and ancillary equipment at the RFP pulp mill in Saint-Félicien, Quebec and the commercial reuse of the captured CO2 by the adjacent Serres Toundra greenhouse facility."

The Engineer: Mechanical trees capture CO2 passively

"The technology involves discs of sorbent stacked in columns. When a column is fully extended, the discs are exposed to air and capture atmospheric CO2. Once full, the discs are them lowered back into the column where the CO2 is extracted and either sequestered or sold for commercial use."
