The Ocean and Carbon Dioxide: Duplicating Hydrothermal Vents and Other Ocean Systems to Manufacture Complex Hydrocarbons from Industrial CO2 Emissions
The Ocean and Carbon Dioxide: Duplicating Hydrothermal Vents and Other Ocean Systems to Manufacture Complex Hydrocarbons from Industrial CO2 Emissions
Session ID#: 78680
Session Description:
We will explore possibilities of engineering systems to duplicate the physical and biological processes at ocean hydrothermal vents to sequester carbon from waste industrial greenhouse gases that may carry heat, hydrogen sulfide, other sulfur compounds, ammonia, carbon dioxide and various hydrocarbons. Salts and metal catalysts would be added to the system to enhance the needed reactions, duplicating ocean physical and biological processes. Industrial waste gases that approximate hydrothermal vents are found in the flares of oil and gas fields, refinery off-gases, and the emissions of coal and natural gas power plants among other industrial sources. Archaea that exist at hydrothermal vents find chemical and thermal energy from the vents, and their carbon from the dissolved carbon dioxide in the ocean waters. We will investigate engineered systems that duplicate the prebiotic and biotic origins of life as may have occurred near hydrothermal vents from amino acid formation and their combining to form peptides and proteins. We conceive of the carbon entering an engineered micro-ocean exiting as long chain hydrocarbons, as organic solids and non-aqueous phase liquids that could be utilized as a fuel source. At the very least green cyanobacteria that occur at fairly deep depths in various seas, and archaea that exist at deep ocean vents provide a biological pathway to sequester carbon. Prebiotic reactions are also a fruitful pathway to consider, as quite reliably demonstrated by variants of the Miller-Urey experiment.
