A sample screenshot of our soil pCO2 sensor data from the recently added new experiments in the #projectcarbdown greenhouse. The purple lines/areas show the CO2 concentrations of the untreated control (=top left graph), the gray line/areas show the readings for the pots with

Our latest blog article tells the story of our fluxmeter army. Our greenhouse has almost 400 pots, a huge number that makes it not feasible to carry out manual CO₂ efflux measurements. At this scale we need an automated solution to do these measurements, especially when short

Published: New working paper with insights from our 2023 greenhouse experiment for measurements of enhanced weathering BACKGROUND We present insights we gained from CO₂ efflux, soil pCO₂ and soil water leachate alkalinity data of 400 greenhouse experiments for enhanced

4 of the Top 100 CDR companies according to XPRIZE are companies in our portfolio: Lithos, 44.01, Vesta, Metalplant. Congratulations for making the list!

Today Sam Davies, the CEO and co-founder of CarbonFlux, visited the #projectcarbdown greenhouse. Flux is a pioneering Carbon Dioxide Removal (CDR) company unlocking the potential of Enhanced Rock Weathering (ERW) in Africa.

We and our work are in Oxford this week at the 3rd Int conference on Negative CO2 Emissions. #negativeco2conference

Greenhouse Adventures: A journey through unexpected obstacles (Part 2) Keeping a long-term monoculture greenhouse experiment with hundreds of pot experiments alive and working over 2-3 years is not as easy as one could think. In our latest blog post, we share the interesting

Our XXL Lysimeter experiment for #enhancedweathering is still alive and kicking. At least once a year we need to clear the XXL lysimeters and surroundings. Now the experiments are in their 3rd year! A report with data from the first 2 years is in the making!

Last week we did a deep dive with a camera into our water cistern. Some lab parameters in our irrigation water surveillance were a bit unusual and we needed to check if there is something in the tank that could be the reason. The video looks a bit like the Titanic will show up in

Conference talk: Testing several MRV approaches in a large-scale ERW greenhouse experiment A conference presentation by our head of science, Jens Hammes Jens Steffen Hammes, at the 3rd International Conference on Negative CO2 Emissions, 2024 in Oxford. carbon-drawdown.de/blog/2024-7-17…

If you are into negative emissions, here is your new favorite documentary! „Legion 44“ is coming!

Three more CDR startups from our portfolio have been selected by Frontier Climate in their fourth round of carbon removal purchases, bringing our portfolio to 6 Frontier winners. Congratulations Flux, Planeteers and Silica! We went through this process ourselves two years ago,

More exciting news this week from one of our portfolio companies: carbonfuture_ announced that they have finalized a Series A investment round led by SIX, a great partner to scale the work of Carbonfuture for the future. CONGRATULATIONS We are proud to continue

From fieldwork last week to #AGU24 conference next week! Our CTO ralfonso.steffanides and our Head of Science Jens Steffen Hammes will be at AGU (American Geophysical Union) Conference 2024 in Washington D.C. next week. You can meet them on Monday (Dec 12th) from 08:30-12:20 EST in the Convention Center, Hall B-C

Preparing our poster for #AGU24 conference using… Bavarian beer! 🍻 Our poster focuses on our CO₂ fluxmeters and how we compared them to current "state of the art" devices. (Poster Code B11L-1475) Meet us on Monday (Dec 12th) from 08:30-12:20 EST in the Convention Center,

We made it to #AGU24! Huge poster session on the first day and loads of interested fellow scientists asking about what we were presenting. Jens Steffen Hammes did a great job here!

That’s what a tiny poster session looks like before thousands of scientists are rushing to look at them…👀

We are proud to be listed as „PHASE I FINALISTS“ by the „Bezos Earth Fund $1M Greenhouse Gas Removal Ideation Prize“. Congratulations to the winners! (14 winners, 64 finalists from over 700 submissions) Our entry was titled: „Monitoring of Carbon Fluxes in Rock-Treated Soils to

Advancing CDR requires good data. In the area of Enhanced Rock Weathering (ERW), look no further than Dirk Paessler’s Carbon Drawdown Initiative wherein Dirk and Ralf Steffens work to measure how fast CO2 is removed under different soil conditions. With the help of their robot

Two years after starting our EW greenhouse experiment we have dismantled 320 of 400 pots and we will continue to monitor 80. Over the next weeks we will build the next set of pots while doubling the size of the experiment. For EW science! Onwards!
