Meysman, Filip J. R.; Montserrat, Francesc (2017): Negative CO2 emissions via enhanced silicate weathering in coastal environments. In Biology letters 13 (4). DOI: 10.1098/rsbl.2016.0905

"Enhanced silicate weathering (ESW) proposes to exploit the natural process of mineral weathering for the removal of CO₂ from the atmosphere. Here, we discuss the potential of applying ESW in coastal environments as a climate change mitigation option. By deliberately introducing fast-weathering silicate minerals onto coastal sediments, alkalinity is released into the overlying waters, thus creating a coastal CO₂ sink. Compared with other NETs, coastal ESW has the advantage that it counteracts ocean acidification, does not interfere with terrestrial land use and can be directly integrated into existing coastal management programmes with existing (dredging) technology."

"I want to cover three other ways to exploit the chemistries of common carbonate minerals for large scale carbon capture and storage. They are less direct, and each has its own issues, but all three are much more energy-efficient than brute force calcination of limestone."

"This paper describes the first study demonstrating the potential of olivine as a soil stabiliser. Olivine has been shown to provide a reactive source of magnesium oxide capable of sequestering carbon dioxide. The effects of olivine additions on consistency limits, compaction characteristics and unconfined compressive strength (UCS) of soil are described."

"Here we present results from laboratory flow-through dissolution experiments which seek to bridge this observational discrepancy by using columns of soil returned to the laboratory from a field site. We constrain the dissolution rate of olivine added to the top of one of these columns, while maintaining much of the complexity inherent in the soil environment."
