Video about Project Carbdown: Fighting climate change with basalt rocks (it works)
Youtuber Patrick Niedermayer has created a great explainer video about enhanced weathering with basalt and about Project Carbdown.
Negative emissions through enhanced weathering: Basalt stone reacts with CO₂ and water. The stone weathers, transforming the CO₂ from the air into harmless carbonates in the soil. The CO₂ is caputred in this form for thousands of years.
This is the basic premise behind Project Carbdown, a scientific field trial that aims to determine exactly how quickly and how much CO₂ can be captured using this process.Ideally, this would allow CO₂ to be extracted from the air on a large scale in agricultural fields.
