Portfolio Spotlight: Climeworks
The world’s leading DAC company just hit another milestone, but they’re not stopping there.
A simple lab test that might be able to predict the suitability of a specific rock/soil combination for EW-CDR
In 2 days instead of 200+ days!
Portfolio Spotlight: Co-reactive decarbonizes construction
Can we use carbon emissions to build our cities?
The story of 4 years of in-field weathering observed by 24 dying soil sensors
The messy truth of measuring enhanced weathering in the real world
Portfolio Spotlight: Flux - Scaling Carbon Removal and Fighting Poverty in Africa
Based in Nairobi, Flux operates on a simple mission: use proven science to reduce carbon in the atmosphere and improve the livelihoods of Kenyan farmers in the process.
Portfolio Spotlight: Silicate - CDR with Calcite
A practical, scalable way to sequester CO₂ by applying carbonate minerals to farmland. It’s enhanced weathering, but faster, cheaper, and already aligned with farming practices.
Portfolio Spotlight: Planeteers - Weathering Limestone Really Fast to Capture and Store CO₂
Planeteers developed a reactor (in a big green shipping container) to accelerate natural carbon capture and storage processes through limestone weathering.
Rebuilding the world's largest greenhouse experiment for EW
... and making it twice as big along the way
Busy weeks - We are preparing several new EW experiments
During spring and early summer 2025 we are preparing new and updated experiments that will help us understand enhanced weathering better.
Portfolio Spotlight: Syntopa — Supercharging Enhanced Weathering with Microbes
What if a few liters of bacteria-laced water could double—or even quintuple—the speed at which rock dust pulls carbon from the atmosphere?
Portfolio Spotlight: Inplanet, EW in Brazil
InPlanet is on pace to spread 200 kilotons of basalt early this year.
Why we are ditching most replicates in favor of having more variations
For our new experiment we will move away from replicating treatments to intentionally choose more variations over more replicates. Here is why.
Portfolio Spotlight: Tropicarbon, EW in Colombia
Tropicarbon decided to tackle agriculture, an industry with some of the highest CO2 emissions.
Climate tech is entering its toughest funding environment in years.
Here are three trends that will make it harder for climate startups to get fresh capital. Plus, there are opportunities, too.
What dismantling an EW greenhouse experiment looks like
In preparation of the next experiment we have dismantled most of our 2023/2024 greenhouse experiment with 400 lysimeter pots over recent weeks.
How we assess the CDR effect of an EW experiment
We use alkalinity measurements comparing treated and untreated pot experiments to measure the CDR effect of a rock dust addition to a specific soil.
