Our proprietary device provides time-integrated measurements of the dissolved molecules produced by weathering, making them the most precise and cost-effective method for tracking carbon sequestration in ERW.
Proprietary technology that simplifies the most expensive, time-consuming component of ERW
Streamlined logistics provide reliable results in a wide range of environment
Our proprietary device provides time-integrated measurements of the dissolved molecules produced by weathering, making them the most precise and cost-effective method for tracking carbon sequestration in ERW.
SIAs are a cheap, simple solution to soil porewater measurement which avoids the costs and logistics of lysimeter sampling.
Once in the ground, SIAs passively absorb ions from the soil column and require no maintenance until the end of the weathering period.
allow us to measure CDR with high precision and efficiency
We deploy SIAs in ERW projects around the world while continuing to test and improve them through active research partnerships.
Soil samples show whether basalt is weathering, but not whether that reaction is truly sequestering carbon.
Porewater
Requires repeated sampling weathering product concentration
Soil sampling
Measure feedstock dissolution over time
Ion-exchange resin
Accumulate Ion-fluxes over one year
SIAs measure true carbon drawdown by capturing both the cations produced by weathering basalt and anions generated by non-carbonic reactions.
Timeline of a typical SIA installation:
1
Positioned below the tilled layer, SIAs do not interfere with normal farming operations and can be installed quickly and cheaply.
2
Continuously captures cation and anion fluxes in soil leachate over 12 months.
3
SIAs are replaced annually to measure cumulative carbon removal over a given weathering period.
4
Total carbon captured over the installation period can be calculated from ion fluxes captured in the device.
Elevate your carbon removal projects with our breakthrough SIAs technology, delivering the highest-quality, most precise monitoring data available.
Our work contributes to the advancement of ERW science and its global scalability.
