Direct air capture (DAC) and conversion of carbon dioxide into valuable chemicals is an eco-sustainable solution to curb the urgent climate crisis. This application demonstrates a practical and scalable solid electrolyte electrochemical cell that can directly uptake CO2 and H2O from air and continuously convert them into basic petrochemical ethylene and oxygen with extremely low voltage potential of 0.6 V and 1 A current. This DAC solid electrolyte reactor can produce approximate 70 milli gram ethylene in 1 hour, about 80% energy efficiency and remain in lower temperature.

Methods are disclosed for the sustainable and scalable production of lithium metal. In one method, lithium salts such as lithium chloride are reduced using low-temperature hydrogen plasma to form lithium metal and lithium hydride. In another method, lithium hydride is thermally decomposed under vacuum or subjected to self-discharging in an Al/LiH/Pd circuit to yield lithium metal. The processes reduce harmful emissions, operate at lower temperatures than molten salt electrolysis, and produce high-purity lithium metal suitable for use in lithium-ion batteries.
