Can be stacked 2 high when full - 330 Gallon Tote


  • 60C - [1]. Yes, 140F. Storage with 24000 BTU comparison - 30C difference for 16 totes (16000 l) is 560 kWhr. Heat pump for 1400 sf is 24000 BTU or 7 kW. This is 80 hours of storage!!! Do it.
  • 160F max temp. [2]
  • 140 F max fill temp on this one- [3]
  • Max fill temperature - [4] - is that continuous or only for filling?
  • Check.png140F [5]
  • Dimensions see [6]
  • Permeation of hydrogen through HDPE - [7]
  • 20 lb propane tank - 4 gal of propane = 3 gge. Thus, 1.3 gge hydrogen is almost half a propane tank.
  • $100/tote easy used. $400/new.
  • Honda 1000EU gives 1kwhr for a quart of gas.
  • Tesla PowerWall is 14kWhr at $14k installed [8]
  • IBC totes for hydrogen yield

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. See Hot Water Heat Pump.
  • 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.

Hydrogen Storage

  • 8 totes, 2 high - 250 gal ea - give 16 cubic meters of storage. 12 cubic meters per GGE. Thus, 1.3 gge and Honda EU1000 equivalent of 5kWhr.
  • Space requirement is a Power House of 16'x16' - considering interior overflow space. Could be part of Utility House with aquaponics.
  • 10kWhr from a 16x16 house module with firewall.
  • 1/2l min hydrogen producer. 33 hours per cubic meter - 17 days per kg.
  • Clearly production rate must increase - which is fine - as the generator is a tiny one at 150W of power. We need a kg/day - or a generator of about 2.4 kW. Which is quite sizeable: gets into real power electronics on a home scale, comparable in complexity to a heat pump.
