Abstract: Methods and systems for producing low carbon intensity hydrogen during electrorefining or electrowinning processes to purify raw metals are provided. The method may include causing an electrorefining or electrowinning process in an electrorefining or electrowinning cell so as to deposit a purified metal at a cathode of the cell. The cell may include one or more anodes, one or more cathodes, and an electrolyte or leaching solution comprising the metal to be purified. The cell may also include an electrical source electrically coupled to the one or more anodes and cathodes such that when the electrical source is operated under electrical potential, the purified metal is deposited at the one or more cathodes from the solution and hydrogen gas is generated. The method may further include operating the cell under one or more operating parameters selected to increase hydrogen gas generation during the electrorefining or electrowinning process.

Abstract: Systems and methods to reduce pour point (PP) temperatures of fat-based compositions for use in transportation fuels. In one or more embodiments, methods and systems reduce the pour point of rendered fats using biologically-derived plant oils for effectively transporting the blended fat based compositions over long distances, thereby advantageously decreasing the heating and mixing requirements needed to maintain the compositional temperature above the pour point. In certain embodiments, the fat based composition comprises rendered animal fats, such as tallow in combination with distilled corn oil (DCO).
