Chemistry World: Ocean motion turns carbon dioxide into renewable fuel

"Scientists have achieved a first in harvesting energy from water waves to make a carbon-based liquid fuel. By generating static electricity from the undulating motion, they are able to convert carbon dioxide into the hydrogen-carrier formic acid."

Earth & Space News: Anaerobic Activity Is a Big Contributor in Marine “Dead Zones”

"Certain parts of Earth’s oceans are so oxygen depleted that they can hardly sustain life. Climate models predict that these “dead zones” will expand as global warming progresses, affecting ecosystems, fisheries, and the climate itself. Now Lengger et al. provide new evidence that such predictions do not adequately account for the activity of anaerobic microbes that consume inorganic carbon within dead zones."

Liu, Yi; et al. (2020): Multicentury Climate Warming Slows Meridional Overturning Circulation, Sequestering Nutrients in the Deep Ocean and Reducing Uptake of Anthropogenic CO2

Liu, Yi, Jefferson Keith Moore, and Francois W. Primeau (2020): Multicentury Climate Warming Slows Meridional Overturning Circulation, Sequestering Nutrients in the Deep Ocean and Reducing Uptake of Anthropogenic CO2. Earth and Space Science Open Archive. January 4, 2020. https://www.essoar.org/doi/10.1002/essoar.10501562.1.

"This Community Earth System Model (CESM) simulation did not include active ice sheet dynamics, but the strong climate warming simulated would lead to large freshwater discharge from the Antarctic and Greenland ice sheets. This would further stratify the polar regions, potentially leading to complete shutdown of the meridional overturning circulation. The impacts of this would be catastrophic as the hothouse Earth climate conditions could be extended for thousands of years, with widespread ocean anoxia developing, driving a mass extinction event."

Lannoy, Charles-Francois de; et al. (2017): Indirect ocean capture of atmospheric CO2. Part I. Prototype of a negative emissions technology

Lannoy, Charles-Francois de; Eisaman, Matthew D.; Jose, Arun; Karnitz, Stephen D.; DeVaul, Richard W.; Hannun, Kathy; Rivest, Jessy L.B. (2017): Indirect ocean capture of atmospheric CO 2. Part I. Prototype of a negative emissions technology. In International Journal of Greenhouse Gas Control. DOI: 10.1016/j.ijggc.2017.10.007.

"We present the design, construction, characterization, and analysis of a prototype process for a novel electrochemical platform of candidate negative emissions technologies (NETs), termed indirect ocean capture. The IOC technologies remove carbon dioxide gas from the atmosphere by leveraging both air-ocean gas exchange and the pH sensitivity of the ocean’s carbonate buffer system. The system characterized in this paper enables two configurations that capture CO2 either as a pure gas or as a solid mineral."

Russ George Blog: First ever major UN Oceans Conference is underway though it is about oceans in spin only

"The key goal of the ocean conference blatantly leaves out vital ocean restoration.Someone must speak for the oceans that need our help to restore them to historic health and abundance."

Greene, Charles H.; et al. (2017): Geoengineering, Marine Microalgae, and Climate Stabilization in the 21 st Century

Greene, Charles H.; Huntley, Mark E.; Archibald, Ian; Gerber, Léda N.; Sills, Deborah L.; Granados, Joe et al. (2017): Geoengineering, Marine Microalgae, and Climate Stabilization in the 21 st Century. In Earth's Future. DOI: 10.1002/2016EF000486.

"Here, we describe an alternative approach based on the large-scale industrial production of marine microalgae. When cultivated with proper attention to power, carbon, and nutrient sources, microalgae can be processed to produce a variety of biopetroleum products, including carbon neutral biofuels for the transportation sector and long-lived, potentially carbon-negative construction materials for the built environment."

Inverse: Super Basic Power Plants Build Mussels

"To geochemist Greg Rau, the future looks like a seaside power plant. More specifically, it looks like a biomass combustion plant that’s actually carbon-negative because the CO2 emissions are dissolved and captured in a mix of seawater and alkaline minerals through a process called chemical weathering. Why does Rau want to see that plant erected, perhaps along the coast near UC Santa Cruz, where he works? Because he believes that energy generation can solve the problems created by energy generation. He believes that this is how you begin to turn back 150 years of carbon dioxide emissions before sea level rise engulfs the landscape and would-be power plant operators have to look for new real estate."
