Oschlies et al. (2024): Perspectives and challenges of marine carbon dioxide removal
Andreas Oschlies, Lennart Thomas Bach, Katja Fennel, Jean-Pierre Gattuso, Nadine Mengis IN: Frontiers in Climate, doi: 10.3389/fclim.2024.1506181
The authors present the current state of knowledge regarding the potentials, risks, side effects as well as challenges associated with technical feasibility, governance, monitoring, reporting and accounting of marine CDR, covering a range of biotic and geochemical approaches. They specifically discuss to what extent a comparison with direct injection of CO2 into seawater, which had been proposed decades ago and is now prohibited by international agreements, may provide guidance for evaluating some of the biotic marine CDR approaches.
