I have some thoughts: Marine CO₂ removal (mCDR) research and development should be carried out by governments, not by startups funded by VCs and philanthropy. These startups will either go belly up soon or sell themselves to a fossil fuel company for greenwashing. carbon-pulse.com/530652
But not all are convinced that private companies are the best route to scaling mCDR. David Ho, a professor of oceanography at the University of Hawaii at Manoa, was part of early mCDR research efforts both within and beyond academia. Ho is an established researcher in ocean science key to the veracity of the field, but he also co-founded a non-profit organisation in 2023 to build software that supports mCDR research.
Ho thinks that the field should be a government-funded or government-run research effort, not driven by companies via venture capital and private funding.
"There's so much that we need to figure out that companies are not going to do. They are there to work on their [own, specific] technology," he said.
Ho pointed to areas of research essential to scaling mCDR - in the realms of environment, geophysics, governance, and social studies - that companies are not necessarily prioritising.
"They're not thinking about that. It's 'How do you develop intellectual property that you can maybe sell to a fossil fuel company?' I bet every single one of them looks at the exit that Carbon Engineering took and says 'Well, we too would like to get $1 bln.' And that's the best exit for any of them right now, because they will never be paid billions of dollars to remove carbon."

Ocean alkalinity enhancement reduces silica ballasting during export due to amplified dissolution
Abstract. Ocean alkalinity enhancement (OAE) is a carbon dioxide removal (CDR) technology proposed to store carbon dioxide (CO2) in the ocean on human-relevant time scales. However, depending on OAE i...

Don’t miss this brilliant article by Dr. Javier Lezaun (Institute for Science, Innovation and Society, University of Oxford) on our 2021 Gran Canaria mesocosm study. A fascinating read about science in action — and beautifully written! 👉 limn.press/article/midd...

In recognition of us doing fuck all to reduce emissions, let me remind y'all that carbon dioxide removal (CDR) is useless unless we decarbonize drastically. rdcu.be/dbFbB

Carbon dioxide removal is not a current climate solution — we need to change the narrative
Drastically reduce emissions first, or carbon dioxide removal will be next to useless.
