In a recent study, researchers from the European Environmental Bureau (EEB), the Stockholm School of Economics (SSE), and the Potsdam Institute for Climate Impact Research (PIK) questioned the planned development of new nuclear capacities in the energy strategies of the United States and certain European countries.
Everyone seems to be focused on electricity production, but ammonia production (ie nitrogen fixation) for fertilizer is often overlooked. Right now it is accomplished mostly with natural gas. If we’re supposed to do it instead with wind and solar, we’re going to have to rely on simple and inefficient electrolysis of water to generate the hydrogen needed for the Haber process. Nuclear power plants have the advange of producing very high temperature steam, which allows for high temperature electrolysis, which is more efficient.
When you consider our fertilizer needs, it becomes clearer that nuclear power will have to play the predominant role in the transition away from fossil fuels.
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?
Yes, we’re definitely going to have to set up more nuclear power plants specifically to make fertilizer. Nuclear heads are literally brain dead
Fertilizer which they can’t make because the steam isn’t hot enough.
Every single pro nuclear argument is a fractal of terrible ideas and gaslighting.
