Production of solar fuels by CO sub(2) plasmolysis

A storage scheme for Renewable Energy (RE) based on the plasmolysis of CO sub(2) into CO and O sub(2) has been experimentally investigated, demonstrating high energy efficiency (>50%) combined with high energy density, rapid start-stop and no use of scarce materials. The key parameter controlling energy efficiency has been identified as the reduced electric field. Basic plasma parameters including density and temperature are derived from a simple particle and energy balance model, allowing parameter specification of an upscale 100 kW reactor. With RE powered plasmolysis as the critical element, a CO sub(2) neutral energy system becomes feasible when complemented by effective capture of CO sub(2) at the input and separation of CO from the output gas stream followed by downstream chemical processing into hydrocarbon fuels.
