Nuclear Power and Preservation of Biomass Carbon are able to realize Carbon Neutrality :

Model Case Iron Product Process

Abstract

In Japan there are many essential industries like Iron product and Cement which cannot exist without fossil fuel like coal. They are hard walls for Carbon Neutrality. So I tried to find the best way to decrease CO₂ emission in Iron product process within now-available technology: Reformed Blast Furnace, Nuclear power, and Recycle, with keeping low product cost as now. The best way I found could decrease CO₂ emission half as now, but another half remain. There is another way using Hydrogen as Iron-Reduction materials. But Hydrogen cost is too much high to product Iron.

I have imaged the future Iron product process when coal-resource will be lost. Carbon is necessary materials for multiple purposes. So then Biomass Carbon product will be increased much more. Then we can use only Biomass Carbon as Iron-Reduction materials. High temperature Nuclear Reactor will be able to be Biomass Energy useful. That is Carbon Solution Reaction. (C+CO₂= 2CO: CO₂ issued from Blast Furnace) In 2050s Biomass Carbon cost will be still too high to replace coal. So I propose Preservation of Biomass Carbon Business is begun to realize Carbon Neutrality. Biomass Carbon is not burn out, but is preserved. Preservation of Biomass Carbon has so high value for Environment Protection, and is bought out by Government expenses, not by tax income. This is MMT Green deal policy.
