From slurry pit to carbon-negative power plant. 🐄⚡
New feature on how German start-up Reverion and buyers’ club Frontier (backed by Google, Stripe, Shopify, H&M Group and others) are turning cattle-farm biogas into megawatts + permanent CO₂ removal.

Das wichtigste Argument gegen CCS an Gaskraftwerken fehlt aber.
Dabei ist die Studie grade vor 10 Tagen rausgekommen und hätte der Journalistin doch ins Auge fallen müssen:
in die, als sicher erachtete Speicherorte für CO2 passen nur 1460Gt. https://www.nature.com/articles/s41586-025-09423-y
Angenommen, wir sind auf CO2zero und möchten nun sicherstellen, dass die Temperatur wirklich nicht weiter steigt.
Dann müssen wir die Feedbacks ausgleichen, die selbst auch Treibhausgase verursachen. Permafrost zB. braucht für mehrere Jahrhunderte 200-300Gt/century (kommt aufs Auftautempo an, klar, also auf unsre fossilen Emissionen.).
Trockengelegte Moore verursachen auch 2Gt/Jahr – muss auch aus der Luft entfernt werden, also 200Gt pro Jahrhundert.
Seht Ihr?
Allein diese beiden Dinge erfordern schon den gesamten identifizierten Safe Storage Space, und dann ist der nach 300 Jahren bis zum Rand voll.
Dann haben wir noch kein CO2 zusätzlich aus der Atmo gesogen, sondern wirklich nur die erreichte Temperatur stabil gehalten.
Wollen wir auch noch CO2 aus der Luft saugen, oder BECCS machen, und das CO2 in den Boden pressen, damit die Konzentration auch sinkt und nicht nur gleich bleibt,
würde das die Zeit verkürzen, in der künftige Generationen noch die Möglichkeit haben, Permafrostfeedback usw auszugleichen.
Fazit:
Wir haben nicht nur keinen Speicher für GasKati, wir haben nicht mal Speicher für Zement, für Landwirtschaft und alle sowas, was Ökonomen als "hard to abate" markieren.
Wir haben nicht genug Speicher für business as usual und Wachstum. Selbst falls wir jemals CO2 im großen Maßstab entfernen können, dann brauchen wir den absolut dringend dafür, um Feedbacks auszugleichen, damit wenigstens die
Temperatur stabil
bleibt.
Und dringend brauchen wir: Rationierungen und Firmenschließungen jetzt und bis die Welt auf CO2zero gekommen ist.
Damit nicht so viel CO2 in der Atmo landet.

#Bioenergy with carbon capture and storage (#BECCS) is a technology that captures and stores carbon dioxide (CO2) from biomass to reduce the amount of CO2 in the atmosphere.

We'll have to do #DACS #BECCS to get CO2 ppm and temperature down.
But we won't have the storage space, the surplus energy, and the agricultural area to sustain such lazy policies as are written in NDC today.
So be sure to tell your government: 20%, even 10% of "residual emissions" is unacceptable!!
Even 1%, totalling at 400Mt CO2eq globally/y is a tall order, seeing how #permafrost, drained #wetlands and other feedbacks need ALL the available carbon storage capacity!

One more thing, then I'll illustrate what worries me in the new paper https://www.nature.com/articles/s41586-025-09423-y
Ofc, it's all rather theoretical. Sucking CO2 from the atmo requires a huge amount of surplus renewables that we won't ever do much #DACS
#BECCS for electricity needs a 2nd power plant next to it to power the actual capturing of CO2 during biomass burning😁 .
Not profitable and also can't grow beyond 3-4Gt/year bc energy plants compete with food and #biodiversity
It's incompatible to #capitalism 🖖🏽

At a storage rate of 10Gt CO2 /year, the identified safe spaces would be filled to the brim in 150 years.
Besides, just to keep temperature stable once fossil emissions have stopped, it is also required to remove CO2-eq annually from
permafrost thaw 4Gt
drained wetlands 2Gt,
and maybe another 4Gt from some other area?
So just to counter the warming from feedbacks fills the identified safe carbon storage locations within 150 years.

Benchmarking the climate mitigation potential of #BECCS [Promoted content]: As the world grapples with the escalating climate crisis, it is becoming increasingly clear that reducing greenhouse gas (GHG) emissions alone will not suffice. Experts globally are turning to negative emissions technologies to actively remove CO2 from the atmosphere, with bioenergy with #carboncapture and storage, known as #BECCS, being a clear frontrunner in the technology race, given its dual… https://www.euractiv.com/section/eet/opinion/benchmarking-the-climate-mitigation-potential-of-beccs/?utm_source=mastodon&utm_medium=dlvr.it
Sollten wir CO₂ in Bäumen einlagern, in Island in den Boden bringen oder auf andere Art und Weise speichern? Im Talk-Podcast sprechen wir über natürliche und technische Lösungen, um überschüssiges CO₂ wieder aus der Atmosphäre zu holen.

"In a context where Europe's land sinks are plummeting, mostly because of overharvesting our #forests and natural disturbances, it seems a terrible misstep for this report to recommend such massive incentives for #BECCS and the role of #carbon markets."

Ah, yes - #BECCS - Better Extract Capital, Scrapping Commitments - is profitable
#ClimateCrisis #Capitalism is not reliable
As this is Mastodon, let me pre-emptively point out that, yes, these scientists are aware that >90% of teaching Climate Neutrality is about emissions reductions, not removals.
The IPCC is also aware of this, as am I at the European Commission.
All these people already wrote reports on that, this one is about land sinks and technological removals.

Atmospheric #CarbonRemoval through “Climate plantations” (bioenergy with carbon capture and storage #BECCS) is limited within #PlanetaryBoundaries, a new PIK study shows. But a more plant-based diet worldwide could free up significant areas. 👇
This publication is our analysis of the draft EU #carbon removal rules for #BECCS and #biochar.
There is a real risk that these methodologies, currently developed by the EU under the #CRCF, end up certifying activities consisting of a mere transfer between the biogenic & geological carbon pools, or even additional CO2 emissions, instead of actually removing it from the air.
