Geochemical Negative Emissions Technologies

Geochemical Negative Emissions Technologies

Over the previous two decades, a diverse array of geochemical negative emissions technologies (NETs) have been proposed, which use alkaline minerals for removing and permanently storing atmospheric carbon dioxide (CO2). This paper reviews the current state of geochemical NETs, highlighting key features (mineral resources; processes; kinetics; storage durability; synergies with other NETs such as DAC, risks; limitations; co-benefits, environmental impacts and life-cycle assessment). The role of organisms and biological mechanisms in enhancing geochemical NETs is also explored.


Global map of geochemical NET companies, projects, initiatives and non-profits featuring Capture6 is included in the full article published by Frontiers in Climate.
