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!

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 army of flux meters, they are creating a database with the data that is needed. Enjoy this snippet or, perhaps watch Legion 44 + remove some carbon while you are at it.

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

[ralfonso.steffanides @RSteffanides]

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

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, Hall B-C (Poster Hall). CTO @RSteffanides and Head of Science @JensHammes will be at @theAGU Conference 2024.

From fieldwork last week to #AGU24 conference next week!

Our CTO @RSteffanides and our Head of Science @JensHammes will be at @theAGU 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 (Poster Hall).

Our poster will focus on our CO₂ fluxmeters and how we compared them to current "state of the art" devices. (Poster Code B11L-1475)

We wish you all a safe journey and look forward to meeting you there and having nice and productive conversations.

@energybants …and did your „study“ also find, that none of the companies which ran those reactors said: „let’s start them again, it’s really worth it!“ ? 🙄

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

We are proud to continue supporting @Carbonfuture as they secure an oversubscribed Series A round. With a focus on scaling the carbon removal market with integrity and efficiency, they’re paving the way for a future where carbon removal has real, measurable impact on the planet. Thrilled to be part of this journey!

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, and it is one of the most selective CDR processes you can imagine! With this work Frontier is pushing the whole industry forward, noone goes through this process with improving!

@SoEineBlinde Ich habe gar keine Frage, ich möchte mich nur bedanken, dass Du diesen Thread eröffnet hast. Habe hier viel durch Dich gelernt. Liebe Grüße aus Fürth!

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

@JacobBukoski @_david_ho_ @ConservationSP @ConservationOrg @SaveTheWaves @csuci Well, but you might add to those calculations that people actually travel to go surfing which implies in cases a substantial amount of their annual carbon footprint just spent for a hobby…

Conference talk: Testing several MRV approaches in a large-scale ERW greenhouse experiment

A conference presentation by our head of science, Jens Hammes @jenshammes, at the 3rd International Conference on Negative CO2 Emissions, 2024 in Oxford.

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 any next moment… 😀

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!

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 journey of combating various pests like powdery mildew, thrips, and aphids which all have tried to wreck our EW greenhouse experiment. For every possible intervention we must consider the potential effects on our weathering experiments.

Discover how we used a natural raw milk treatment to successfully eradicate powdery mildew, leaving our plants healthy and thriving. Learn about our creative approach to managing thrips with lacewing larvae and predatory mites. Despite some initial challenges, our efforts paid off, resulting in a significant reduction of these pesky pests.

Finally, read about our battle with aphids and how ladybug larvae became our new allies. These tiny, beneficial insects are helping us keep aphids at bay, ensuring our plants remain vibrant and healthy. Click the link to dive into our full story and see how we're keeping our greenhouse green and pest-free!

@RobertHoglund @StefanFSchubert I don’t think so. People rather would like the hand rule to change… and the VAR decisions to be quicker. It works really well in a lot of other sports very precision and accuracy is needed.
