Please, read the thread carefully. The point is that with VHTRs you don't need the usual electrolysis to split water into hydrogen and oxygen. Instead you can use high temperatures produced by a reactor to power conversion directly, thus improving the process efficiency. The most common option is the sulfur–iodine cycle. Granted, it's not so suitable for producing hot pressurized hydrogen (though it may be possible to separate iodine and hydrogen without condensation), but there are other options for thermochemical water splitting like high temperature electrolysis, which requires less electricity than electrolysis under STP.
