    No on all fronts.

    The only reactor designs with any sort of history don’t produce steam at high enough temperature for the sulfur cycle and haber process.

    The steam they do produce costs more per kWh thermal than a kWh electric from renewables with firming so is more economic to produce with a resistor.

    Mirrors exist. Point one at a rock somewhere sunny and you have a source of high temperature heat.

    Direct nitrogen electrolysis is better than all these options. It’s had very little research but the catalysts are much more abundant than hydrogen electrolysers and higher efficiencies are possible.

    Using fertilizer at all has a huge emissions footprint (much bigger than producing it). The correct path here is regenerative agriculture, precision fermentation and reducing the amount of farmland needed by stopping beef. Nitrogen electrolysis is a good bonus on top of this.
