According to Wikipedia potassium carbonate has a density of 2.4 tons per cubic meter(1). So ten cbm will fit on a full size truck (eu). That is 3610kWh of heat energy.

Let’s assume a price point of 0,1€/kWh heat(2), a truck load would carry heat with a cargo worth of 361€.

I wonder how far it can be transported unless it’s more expensive than traditional heat sources.

Could they somehow double the heat per weight, this would be a thing.
