Coordinated Energy Systems
Tightly Coupled Hybrid Systems
• Holistic Integration of the energy system
• Involve electrical, thermal, and chemical networks
• Utilize energy storage on various scales
• Provide reliable, sustainable, low-emissions, most affordable energy
• Involve thermal, electrical, and process intermediates integration
• More complex than co-generation, poly-generation, or combined heat and power
• May exploit the economics of coordinated energy systems
• May provide grid services through demand response (import or export)

• Evaluation of Hydrogen Production Feasibility for a Light Water Reactor in the MidwestRepurposing existing Exelon plant for H2 production via high temperature electrolysis; use of produced hydrogen for multiple off-take industries (ammonia and fertilizer production, steel manufacturing, and fuel cells) (INL/EXT-19-55395)
• Evaluation of Non-electric Market Options for a Light-water Reactor in the MidwestLWR market opportunities for LWRs with a focus on H2 production using low-temperature and high-temperature electrolysis; initial look at polymers, chemicals, and synfuels (INL/EXT-19-55090)
Recent Hydrogen Production Analyses for Current Fleet LWRs
INL issued public-facing reports on in FY19 that provide the foundation for demonstration of using LWRs to produce non-electric products:

Example Test for Non-Spinning Reserve: Electrolyzer ramps down in 10 mins while NPP dispatches electricity
to the grid; then returns to full load after onehour.
• Purpose & Scope1. Demonstrate hydrogen production using direct electrical power offtake from a nuclear power plant for a commercial, 1-3 MWe, low-temperature (PEM) electrolysis module2. Acquaint NPP operators with monitoring and controls procedures and methods for scaleup to large commercial-scale hydrogen plants3. Evaluate power offtake dynamics on NPP power transmission stations to avoid NPP flexible operations4. Evaluate power inverter control response to provide grid contingency (inertia and frequency stability), ramping reserves, and volt/reactive control reserve5. Produce hydrogen for captive use by NPPs6. Produce hydrogen for first movers of clean hydrogen; fuel-cell buses, heavy-duty trucks, forklifts, and industrial users
• Two projects: (1) Exelon, (2) Energy Harbor Partnership with Xcel Energy and APS
• INL and NREL role: Support utilities with project test planning, controls and monitoring environment implementation and testing, data collection, systems performance evaluation, and project reporting.
