| Abstract Scope |
Design of new electrified and decarbonized metal production processes intended for large-scale operation have an opportunity to use intermittent solar and wind electricity as the new lowest-cost generation technologies. Intermittency can be partially mitigated by batteries and other energy storage, but an economically optimal electrical grid will inevitably have excess energy at some times and shortages at others. This talk will describe an optimization framework and algorithm for determining the best times of day and parts of the year to run, considering startup and shutdown costs as well as variable electricity price. It will discuss application of this algorithm to Flow Electrolysis, an aqueous electrolytic iron powder production process operating at 80-100ºC, and molten salt electrolysis for reduction of magnesium oxide around 1000ºC. We show that in this new electricity generation landscape, low capital cost and flexibility can be more important than energy efficiency. |
