REopt Optimizes Nuclear-Renewable Hybrid Energy Systems
NREL used the REopt™ model to optimize the design and operational schedule of several nuclear-renewable hybrid energy systems. One would be used to produce a synthetic gasoline drop-in liquid fuel, a second would power a desalination plant, several more provide heat to industrial processes, and others electrolyze water to produce hydrogen. Nuclear-renewable hybrid energy systems are a technology that can generate very low-carbon, dispatchable electricity and provide very low-carbon thermal energy for industrial processes at a lower cost than alternative energy sources.
REopt was used to optimize the subsystem sizes and dispatch strategy to maximize net present value of the nuclear-renewable hybrid systems under a variety of electricity price vectors and thermal energy prices. Electricity price vectors were generated using the PLEXOS production cost model with a high penetration of renewable generators. NREL also performed sensitivity checks on many of the parameters to indicate impacts of uncertainty and validate conclusions.
