CDR Measurement for ERW via Alkalinity in Leachate (Data From Our Greenhouse Experiment, Part 2)
Carbon Drawdown Initiative, December 1, 2023
In this paper the authors delve into Enhanced Rock Weathering (ERW) and its potential for Carbon Dioxide Removal (CDR) in agricultural settings. They present the first results of our extensive greenhouse experiment that was started early 2023 with the goal to measure the climate-positive effects of ERW on relatively short timescales (months to a few years). To achieve this they are experimenting with several measurement approaches. One of them is based on analyzing alkalinity in leachate waters, the topic of this paper where the authors both explain how it works and what the first results tell us.
