We cannot reach our climate goals without harnessing the power of nature. Very pleased to speak with Sussan Ley about mobilizing nature-based and ocean-based solutions to address the climate crisis. #OceanClimateAction #ForNature

The special issue: 'The Role of Ocean-Based Negative Emission Technologies for Climate Mitigation' is now complete. A summary of all articles can be found 👇 frontiersin.org/article/10.338…

XPRIZE: pls do some CO2 removal WORLD: ya but measuring it is hard XPRIZE: we want to fund innovation in measurement too! Funding opportunity: $100k awards for proposals in measurement, reporting, verification of CO2 removal solutions. Tell everyone! DEADLINE OCT. 1

A new National Academies report provides a path forward for research and development needed to assess the viability of #OceanCarbonRemoval approaches. Read more about #CDRStrategies: nap.edu/catalog/26278/…

For #AGU21 goers interested in ocean CDR: join us on Thursday in New Orleans as we launch an ambitious R&D program focused on ocean alkalinity enhancement. We’ll publish two big RFPs and hope to see you there. eventbrite.com/e/ocean-alkali…

Attention AGU (American Geophysical Union) meeting attendees: Join Ocean Visions and Additional Ventures TOMORROW at 7:30PM at Mulate's for nola mojito and grilled alligator and hear about an ambitious ocean alkalinity enhancement R&D program we’ll be partnering on. Register here: bit.ly/oaerfp

If you at at AGU (American Geophysical Union) fall meeting, please join Ocean Visions and Additional Ventures to raise a glass and talk ocean alkalinity based CDR. Thursday 7:30

ANNOUNCEMENT: Additional Ventures is partnering with Ocean Visions and philanthropic partners, putting $10M+ forward to answer key science questions on ocean alkalinity enhancement. Pre-proposal deadline 2/25/22. See details and submission process: oceanvisions.org/request-for-pr…

Could the efficiency of #OceanAlkalinityEnhancement be reduced through an Earth System Feedback where more alkalinity stimulates biotic calcification thereby reducing alkalinity again? We'll investigate this with funding from Additional Ventures and we'll hire a postdoc. More below👇

Robert Höglund Lennart Bach Scaling to climatically relevant scales would require HCl disposal. It would be great if someone knowledgeable would write a paper comparing costs and challenges of HCl vs CO2 disposal at scale.

Now accepting pre-proposals to get between $750k-$1.5M of funding each to develop prototypes that could enable safe, cost-efficient, and scalable OAE as a potential method for large-scale carbon dioxide removal (CDR). Tell your friends to apply! additionalventures.org/news/announcin…

The final post in a series of super insightful contributions from Dai Ellis about the near-future decisions that we'll face as we shape the CDR marketplace. All signs point to MRV as the hardest nut to crack and among the most important ones to focus on.

Such a well-written overview on geochemical CDR approaches, their differences and commonalities. The sub-title should be "the future is alkaline".

The OAE MRV challenge

Very elegant modeling exercise by @David_Koweek suggesting that artificial upwelling will not be a large player in the ocean CDR league

Excited to share my new post with reflections on the "who" question in carbon removal—the waves of actors who will need to meet the move-mountains challenge in front of us. Who's got next? Philanthropy and heavy industry. 1/2 greatunwind.substack.com/p/whos-got-next
