🛌 Wissen fürs Kopfkissen: 📖
Wie viel CO₂ lässt sich wirklich dauerhaft unterirdisch speichern?
Zwischen ambitionierten Versprechen, Hochrechnungen und realistischen Schätzungen liegen Welten. Wenn dann noch vermeidbare fossile Emissionen gespeichert werden, ist das sowohl schlecht für den #Klimaschutz als auch für die wertvollen Speicherressourcen.

New US bill H.7656 just dropped: supporting marine carbon dioxide removal activities. Referred to the Science, Space & Technology Committee.
Ocean CDR is getting serious legislative attention — this matters for ocean alkalinity enhancement, seaweed sinking, and electrochemical approaches. Policy is finally catching up to the science. 🌊⚗️
The "reduction vs. removal" framing was always a false choice. We need both — and fast.
Canada has massive CDR potential: vast basalt deposits for enhanced weathering, long coastlines for ocean CDR. But regulatory frameworks lag behind. Social license comes from transparency and science. 🇨🇦🪨

DAC doesn’t scale on chemistry. It scales on power.
West Texas: 500 MW solar ↔ STRATOS (500k t/yr). The question: can carbon removal scale without cannibalizing clean electricity?

Your weekly CDR reading list just dropped. 📚

The first EPA-permitted ocean alkalinity enhancement field trial — and results are being presented TODAY at #OSM26 in Glasgow. 🌊
WHOI's LOC-NESS project tested adding alkalinity to seawater in the Gulf of Maine to lock CO₂ in the ocean.
If the science checks out, OAE could be a massive CDR pathway. Transparency and community engagement are key.
This is the nuance CDR needs more of.
ERW has real potential — 350Mt CO₂/yr by 2050 — but the path from lab promise to field reality is full of open questions: toxic trace elements, uncertain carbon tracking, limited rock supply.
Honest take: we need to scale AND solve MRV at the same time.

One CDR method delivers over 90% of all commercially traded permanent carbon removal credits.
It's not DAC. It's not enhanced weathering.
It's biochar. An $838M market in 2026, heading to $2.3B by 2034. Credits stabilized at ~$150/tCO₂e.
The quiet giant of carbon removal.
The world's largest Direct Air Capture plant just got its own 500MW solar farm. ☀️
Origis Energy's Swift Air Solar complex in Texas is now fully online — dedicated renewable power for Occidental's STRATOS DAC facility.
DAC powered by fossil fuels never made sense. This is how it should work.
Crush rocks, spread on fields, remove CO₂. Simple?
A new Nature paper maps everything that could go wrong with Enhanced Rock Weathering — toxic trace elements, uncertain carbon tracking from soil to ocean.
ERW is promising. But honest science means naming the hard parts.
