• Marine carbon dioxide removal (CDR) initially drew enthusiasm from the private sector, but momentum is slowing down.

    In this context, “private sector” means Microsoft. They’re the one throwing tons of money at CDR projects. Seems they may be starting to learn that dead zones and ocean acidification aren’t worth the overhyped gains

    • It still seems like the only possibly scalable solution. A hypothetical genetically engineered plant being dumped from ships in an ocean dead zone / desert, where it will do photosynthesis and drop pellets of heavier than water (nondegradeable) biopolymer to the ocean floor. No need to dump the fertilizer itself if the plant can store enough when it’s bred in a floating bioreactor. It only needs to produce polymers.

      Only in the vast ocean deserts could we use exponential growth of plants and the abundant solar energy and space.
