    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.

    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.

      One way or another, I’m pretty sure that we need fertilizer. What is the source of GHG if the fertilizer is produced without natural gas or other fossil fuels?
