Abstract: A solid oxide cell device is provided which uses hydrocarbon fuel gas and oxygen to remove carbon dioxide from a gas stream, converting it to syngas (carbon monoxide and hydrogen), preferably without any input of external energy beyond that derived from the input gases. Existing processes can then be used to convert the syngas to stable liquid or solid organic chemicals, so that all the input carbon is fixed. Partial oxidation of hydrocarbon fuel gas in a solid oxide fuel cell produces syngas and electricity, and the electricity powers a solid oxide electrolyser which reacts carbon dioxide with further hydrocarbon fuel gas to produce more syngas. The fuel cell and electrolyser together can achieve self-sustaining carbon dioxide utilization.

Abstract: Described herein are electrochemical-additive manufacturing methods and systems using such methods. A method comprises depositing a material onto a deposition electrode by flowing a current between that deposition electrode and each of multiple individually-addressable electrodes, forming an electrode array. These currents are independently controlled based on a target map and using deposition control circuits, each coupled to one individually-addressable electrode. The target map is generated by a system controller based on various characteristics of the system (e.g., the performance of each deposition control circuit and/or individually-addressable electrode, electrolyte composition) and the desired characteristics of the deposited material (e.g., deposition location, uniformity, morphology). Furthermore, when the deposition electrode and the electrode array move relative to each other, the system controller dynamically updates the target map based on their relative positions.
