“…Nuclear-assisted hydrogen production schemes combining thermochemical water splitting driven by nuclear reactor waste heat, and nuclear power-driven high-temperature electrolysis, have been presented in [138][139][140][141]. Orhan et al [141] suggested the copper-chlorine (Cu-Cl) cycle as a promising low-temperature process for integration with a wide range of nuclear reactors.…”

“…Hydrogen production could also be extended to SNG production as illustrated in Figure 4. Due to direct heat utilization, the nuclear fuel to thermo-chemical hydrogen production pathway could be of higher efficiency (i.e., up to 60% [140]) than the conversion of a fuel or energy source to electricity first and then to hydrogen via electrolysis [139].…”

“…O'Brien [140] proposed a conceptual high-temperature (~850 • C) SOE-based steam electrolysis system powered by both off-peak, low-cost electricity generated by an advanced nuclear reactor, and a high temperature heat source from either the primary helium reactor coolant, concentrated solar or biomass gasification installations, for large-scale production of hydrogen. This concept was thought to be more cost-effective than renewable electricity-driven electrolysis in the immediate future.…”

Technical, economic and environmental assessments of projected power-to-gas (PtG) deployment scenarios at distributed-to national-scale are reviewed, as well as their extensions to nuclear-assisted renewable hydrogen. Their collective research trends, outcomes, challenges and limitations are highlighted, leading to suggested future work areas. These studies have focused on the conversion of excess wind and solar photovoltaic electricity in European-based energy systems using low-temperature electrolysis technologies. Synthetic natural gas, either solely or with hydrogen, has been the most frequent PtG product. However, the spectrum of possible deployment scenarios has been incompletely explored to date, in terms of geographical/sectorial application environment, electricity generation technology, and PtG processes, products and their end-uses to meet a given energy system demand portfolio. Suggested areas of focus include PtG deployment scenarios: (i) incorporating concentrated solar-and/or hybrid renewable generation technologies; (ii) for energy systems facing high cooling and/or water desalination/treatment demands; (iii) employing high-temperature and/or hybrid hydrogen production processes; and (iv) involving PtG material/energy integrations with other installations/sectors. In terms of PtG deployment simulation, suggested areas include the use of dynamic and load/utilization factor-dependent performance characteristics, dynamic commodity prices, more systematic comparisons between power-to-what potential deployment options and between product end-uses, more holistic performance criteria, and formal optimizations.

“…Nuclear energy can also contribute directly to the transportation sector by supplying carbon-free electric power for recharging battery-electric vehicles (BEV). Analysis has shown that all US light-duty vehicle miles could be powered by 130 GW of supplemental power generation, assuming that the light-duty fleet consists of HFCV/BEVs that have 40 mile electric range and that the hydrogen needed for extended range in HFCV mode is generating using high-temperature electrolysis [1].…”

Two hybrid energy processes that enable production of synthetic liquid fuels that are compatible with the existing conventional liquid transportation fuels infrastructure are presented. Using biomass as a renewable carbon source, and supplemental hydrogen from high-temperature steam electrolysis (HTSE), these two hybrid energy processes have the potential to provide a significant alternative petroleum source that could reduce US dependence on imported oil. The first process discusses a hydropyrolysis unit with hydrogen addition from HTSE. The second process discusses a process named Bio-Syntrolysis. The Bio-Syntrolysis process combines hydrogen from HTSE with CO from an oxygen-blown biomass gasifier that yields syngas to be used as a feedstock for synthesis of liquid transportation fuels via a Fischer-Tropsch process. Conversion of syngas to liquid hydrocarbon fuels, using a biomass-based carbon source, expands the application of renewable energy beyond the grid to include transportation fuels. It can also contribute to grid stability associated with non-dispatchable power generation. The use of supplemental hydrogen from HTSE enables greater than 90% utilization of the biomass carbon content which is about 2.5 times higher than carbon utilization associated with traditional cellulosic ethanol production. If the electrical power source needed for HTSE is based on nuclear or renewable energy, the process is carbon neutral. INL has demonstrated improved biomass processing prior to gasification. Recyclable biomass in the form of crop residue or energy crops would serve as the feedstock for this process. A process model of syngas production using high temperature electrolysis and biomass gasification is presented. Process heat from the biomass gasifier is used to heat steam for the hydrogen production via the high temperature steam electrolysis process. Oxygen produced form the electrolysis process is used to control the oxidation rate in the oxygenblown biomass gasifier.
