Environmental and health impacts of atmospheric CO2 removal by enhanced rock weathering depend on nations’ energy mix [PDF]
Communications Earth & Environment, 2022 Enhanced rock weathering is competitive with other carbon sequestration strategies in terms of land, energy and water use with its overall sustainability dependent on that of the energy system supplying it, according to a process-based life cycle ...

Enhanced chemical weathering of rocks during the last glacial maximum: a sink for atmospheric CO2? [PDF]
Chemical Geology, 1999 Abstract It has been proposed that increased rates of chemical weathering and the related drawdown of atmospheric CO2 on the continents may have at least partly contributed to the low CO2 concentrations during the last glacial maximum (LGM). Variations in continental erosion could thus be one of the driving forces for the glacial/interglacial climate

Soil Structure and Mixing Controls on Water‐Rock Contact: Implications for Enhanced Weathering [PDF]
Water Resources ResearchEnhanced weathering (EW), the addition of finely ground silicate rock powder (RP) to soil, has emerged as a promising carbon removal strategy. However, quantifying weathering rates in soils remains challenging, as most continuum‐scale EW models do not ...

Potential and costs of carbon dioxide removal by enhanced weathering of rocks [PDF]
Environmental Research Letters, 2018 The chemical weathering of rocks currently absorbs about 1.1 Gt CO _2 a ^−1 being mainly stored as bicarbonate in the ocean. An enhancement of this slow natural process could remove substantial amounts of CO _2 from the atmosphere, aiming to offset some ...

New estimates of the storage permanence and ocean co-benefits of enhanced rock weathering. [PDF]
PNAS Nexus, 2023 Abstract Avoiding many of the most severe consequences of anthropogenic climate change in the coming century will very likely require the development of “negative emissions technologies”—practices that lead to net carbon dioxide removal (CDR) from Earth's atmosphere. However, feedbacks within the carbon cycle place intrinsic limits on

Suitability of rocks, minerals, and cement waste for CO2 removal via enhanced rock weathering. [PDF]
Commun ChemMineral and rock additions to the environment have been proposed as a pathway to remove atmospheric CO2. This process occurs when hydrated minerals or rocks increase alkalinity, promoting the formation of bicarbonate. In this study, we evaluate the potential of commonly used hydrated rock and mineral powders to enhance alkalinity and react with both ...
