CO2 reduction driven by a pH gradient

[QUOTE="BillTre, post: 6312579, member: 581757"] [B]TL;DR Summary:[/B] A proposed method in which organic molecules could be produced abiotically has been demonstrated in a lab. In the world of Origin of Life hypothesizing, there now seem to be two main competing approaches. Life originating at alkaline hydrothermal vents and an origin in intermittent terrestrial pools (exposed to periods of drying) getting outflow from volcanically heated water sources. The alkaline hydrothermal vent hypothesis depends upon particular reactions dependent on electrochemical potential between ocean water and the outflow of the alkaline hydrothermal vents. To my knowledge, until now these reactions have not been demonstrated. Here is a abstract of a paper I found on https://www.researchgate.net/publication/339699873_CO2_reduction_driven_by_a_pH_gradient: Still waiting to get a copy of the full paper, but it sounds exciting to me.
