Optimized Variable Production (OVP) Model
Foundational approach to TEA and LCA of power-to-x using intermittent and/or variably priced energy sources
Simultaneous optimization of technology selection, sizing, and scheduling of entire power-to-x facility toward lowest production cost and/or life cycle impact
Scheduling using high resolution, long horizon time series data to account for diurnal and seasonal variability in power availability, commodity demands
Formulated as integer linear model to systematically determine optimal tradeoffs between all design and operational considerations
Easily adjustable to different power-to-x products and demand profiles, input power sources and prices, and technology alternatives
