Three partly coupled integrated nuclear energy systems are described. These enable base-load reactors to provide fully dispatchable electricity without greenhouse-gas emissions, thus replacing gas turbines burning natural and batteries storing electricity. hybrid link the industrial sector sector. Firstly, electricity-to-high-temperature (1800 °C) gigawatt-hour firebrick heat storage converts low-price high-temperature stored for industry power generation. Secondly, Nuclear Air-Brayton Combined Cycles (NACC) with thermodynamic topping cycles using or combustible fuel Peak output can be two five times production. The heat-to-electricity efficiency of exceeds 70%. Thirdly, hydrogen production markets enables where is used but not produce Base-load send grid and/or electrolyzers depending upon prices. Low-cost us meet steady-state demands, even though varied. Hydrogen uses (ammonia fertilizer, direct reduction iron ore coke, cellulosic liquid hydrocarbon biofuels crude oil) may exceed 20% total demand a massive source storable when depleted.
