The results also indicated that the chemical conversion rate of hydrogen production was in direct proportion to the mass of Na2CO3, while the solid product was Na2UO4, instead of Na2U2O7. Nevertheless the thermochemical cycle used for hydrogen generation can be closed, and chemical compounds used in these processes can also be recycled. So the cycle with Na2UO4 as its first reaction product has an advantage over the proposed UTC process, attributed to the fast reaction rate and high hydrogen yield in the first reaction step.
