Energy Storage
- From 80F to 140F, we have 60F, so using Water Heating Calculator - we get 37 kWhr stored per tote. 24000 BTU is 7 kW.
- Thus, we store 5 hours of a heat pump's thermal output in a single IBC tote! This is very much practical for thermal storage in winter.
- We would need 5 totes to store heat for one day, 10 totes for 2 days' worth. This appears to be a practical option.
- However, standard heat pumps output 92F heat. Thus, a different working fluid would need to be used to achieve a higher temperature. This would be a good point of innovation for off-grid storage
- The immeidiate solution is to use PV to heat via resistive heating. We would need a minimum of 16 hours heat per day, or 112 kWhr. Assuming only 6 hours of light in the winter, this would need a 19kW PV panel system. Not good. Or, a wind turbine.
