High Performance ReductionOxidation Metal Oxides for Thermochemical Energy Storage (PROMOTES) High Performance Reduction/Oxidation Metal Oxides for Thermochemical Energy Storage (PROMOTES) Statement of Work Task 3.3.2 Systems Analysis, Optimization, and Techno-Economic Modeling Task High Level Energy& Efficiency Modeling Milestone: Year 1 Steady State thermodynamic quasi-equilibrium, 1D Model constructed, model parameters established, preliminary results on energy flows, efficiencies, and trade-offs delivered Milestone: Year 2 Model refined and validated against experimental results. Simulation of prototype scale reactors delivered and projection to larger scale delivered demonstrating efficiency improvements possible. Milestone: Year 3 Model further refined and embedded in full system, results on embedded reactors (solar receiver reduction reactor and re-oxidation reactor) delivered and projection to full scale delivered demonstrating energy efficiency metrics achievable. Task Resource Modeling, Availability and Market Conditions Milestone: Year 1 Resource analysis for system delivered grams/kWh storage Milestone: Year 2 Limitations assessed from market conditions material usage targets delivered as materials classes are refined Milestone: Year 3 Cost of material resources for the active materials as fraction of the $15/kWh determined<50% of total thermal storage system and target for lifetime/replacement schedules to meet cost target. Task Techno-economic assessment to relate design variables, performance targets, and cost metrics Milestone: Year 1 Techno-economic model and assumptions delivered showing cost targets can be met providing certain performance targets and reactor/materials design constraints are achieved. Milestone: Year 2 Techno-economic model for the specific system design and identified high leverage performance and design parameters to optimize for cost. Milestone: Year 3 Techno-economic model for system at scale and specific design parameters that can achieve $15/kWh
