Table 2: Available energy for hydrogen production in cogeneration scenario, by time of day

1 January 2000

*Percentages from power consumption statistics of Ontario, Canada [10]**Designed full power capacity for single SCWR assumed to be 1000 MWe***Calculations assume 20% heat loss from SCWR-hydrogen plant transfer. Net heat input required by the Cu-Cl cycle is 227 MJ/kgH2, assuming 50% of heat from exothermic reactions is reused inside the Cu-Cl cycle [24, 28]
