Abstract
The H2Mare subproject PtX-Wind supported by german government is developing economically feasible methods for creating methanol and other products offshore and independent of the power grid. There is a focus on optimizing operations amidst natural wind power fluctuations.
The approach involves a two-stage mixed integer optimization process, starting with an economic analysis to optimize investments in the individual subsystems (components) using the availability of wind power during a type year. The system's operation schedule is optimized in a rolling 2-weeks horizon considering flexibility options for each plant component, such as changing discrete operating points to partial load, scheduled manufacturing using interim product storage and the usage of a battery storage to cover short lull. A demand-side-management approach is thus applied to process engineering. Accuracy of transmission function descriptions as well as material interconnections between system components are studied to improve overall optimization results and performance.
In the further work the optimization is to be applied by means of a software-in-the-loop and expanded to a stochastic optimization.
The research contributes to renewable energy integration by establishing the feasibility of cost-optimized, grid-independent operation for hydrogen-based Power-to-X systems. The findings will inform future energy policy and industrial uses.
