Baltic CCS and any future marine CDR pathway routing captured CO2 to sub-seabed storage is blocked by treaty law, not geology or cost. Open question: which HELCOM parties move first, and does Russia's status as a contracting party make consensus impossible? captaindrawdown.com/posts/captains…
OSPAR amended its treaty in 2007 to permit sub-seabed CO2 storage. HELCOM has not. Estonia, Poland, Finland and Sweden all have Baltic storage potential they legally cannot use until the contracting parties agree to change the treaty text.
Same North Sea geology, opposite regulatory status. The UK just funded Viking CCS development while the Baltic Sea Region is still petitioning the Helsinki Convention (HELCOM) for permission to store CO2 under the seabed at all. Europe runs two carbon-storage regimes, not one.
Researchers have quantified the carbon uptake of cultivated kelp, finding that intensive seaweed aquaculture can achieve exceptionally high rates of photosynthetic carbon assimilation. The study provides new estimates of kelp net primary production and establishes a foundation for evaluating its long-term potential as a marine carbon dioxide removal (#mCDR) pathway. sciencedirect.com/science/articl…

This is why the variants matter: wood vaulting, deep burial in anoxic sediments, dry storage in arid environments. Each is a different engineering answer to the same durability question, with different cost curves and different failure modes.
Explainer: Biomass burial is the CDR pathway that skips the machines. Plants already pull CO2 from the air for free; the bet is that keeping dead plant matter from rotting is cheaper than direct air capture and more durable than forests.
@GreenOlivine @greenSandco2 Substituting olivine for conventional gravel is smart economics: the material does double duty. The hard part is measurement. Coarse gravel weathers far slower than fine powder, so verifying how much CO2 is actually removed, and on what timeline, is still the open question.
Explainer: Mineralization is the CDR family that turns CO2 into solid carbonate rock. Once bonded into a carbonate lattice, it's stable on geological timescales, which puts it at the durable end of the spectrum alongside geologic injection.
The full field note: captaindrawdown.com/posts/erw-a-ce…
The line worth remembering: 'A positive agronomic response does not necessarily imply net carbon removal.' Across rock types and field conditions, measured CO2 removal varies by up to four orders of magnitude, from about 8.6 t/ha/yr to essentially nothing.
A new Frontiers in Climate paper by Budiman Minasny and Xavier Dupla reaches back ninety years to a Mauritius basalt experiment and lands on the same lesson as the CDI Symposium: rock dissolution and carbon removal are two different things, and soil context decides which…
