Paulo, Carlos; et al. (2021): Evaluating feedstocks for carbon dioxide removal by enhanced rock weathering and CO2 mineralization

Paulo, Carlos; Power, Ian M.; Stubbs, Amanda R.; Wang, Baolin; Zeyen, Nina; Wilson, Siobhan A. (2021): Evaluating feedstocks for carbon dioxide removal by enhanced rock weathering and CO2 mineralization. In Applied Geochemistry, p. 104955. DOI: 10.1016/j.apgeochem.2021.104955.

"We have developed a new method to evaluate the reactivity of mineral feedstocks that consists of a batch leach test using CO2 coupled with total inorganic carbon (TIC) analysis to quantify easily extractable Mg and Ca from non-carbonate (desirable) cation sources."

PhD opportunity: Impact of soil biota on enhanced silicate weathering in a bio-reactor (Wageningen University & Research)

Deadline: 30. April 2021

"As PhD student you will work in a multidisciplinary project on accelerating mineral weathering by biotic activity (https://www.fet-bam.eu/). Supported by project partners, you will take the lead in designing, conducting and analysing batch reactor experiments in order to enhance the weathering of silicate minerals, a carbon dioxide removal technology resulting in long-term carbon sequestration."

Blog: ICRLP: A Praise for Basalt Potential: In situ mineral carbonation

"A variety of igneous rocks and minerals are currently under evaluation as potential prospects to facilitate permanent carbon sequestration. Olivine, serpentine, and peridotite are some of the many that bind with carbon dioxide to form carbonates, hence providing a more permanent removal of captured carbon. This post is about a rock that deserves more attention: basalt."

Carbon Drawdown Initiative: Introducing “Project Carbdown”: Our first “enhanced weathering” field trial aims to remove CO₂ from the atmosphere

"The weathering of rock permanently binds CO₂ from the air and thus removes it from the atmosphere. Can this be used to mitigate climate change? For a few months now, we have been preparing a scientific project together with several scientists and our partner Fieldcode in which we want to accelerate and measure the weathering of rocks, in order to possibly expand the toolbox for climate protection."
