For comparison, mass-produced SOH gas generators today perform 3.8-4.8 Wh/L, or about 10 times more.
Based on the results shown in the table above, an example, 1m3 / 1,000 liters of SOH-gas-producing Water-electrolysis Vessel, called ELECTROLYZER ( or LYZER for short ), with the respective number and size of electrolysis cells, similar to ours, will produce 1m3 (1,000 liters) of SОH gas mixture with 380Wh or 0.38kWh power.
According to our measurement tests conducted, 1m3, or 1,000 liters of SОH gas weighs 0.535 kg/m3 at 0,45 bar pressure and 20deg.С .
1L SOН => 0.38Wh
1000L SOН = 0.535 kg OН => 380Wh = 0.38kWh/m3
PURE HYDROGEN weighs 1/9 of the SОН, because the H2 molecule’s molar mass is 2 g/mol, and the SОН’s molar mass is 18 g/mol, or 9 times more.
So, 1m3 (1,000 liters) of SОH gas, produced by our cell, contains :
0.535 kg SOH : 9 = 0.06 kg (60 grams) of PURE HYDROGEN, produced with 0.38 kWh, at 0.45 bar / 20deg.C .
Scaling-up 4 times and multiplying our super-efficient electrolysis cell, we can make an SOH ELECTROLYZER (Lyzer) with sizes : 500/250/250 mm, comprised of 320 cells ( 8 clusters, 40 cells each) :
Based on the photo of the table above, our basic cell produces SOH with 0,72 Wh/L power.
So, for example, a 4-times scaled-up electrolysis cell in the 4-times scaled-up Electrolyzer, could produce for example 2.2 L/h SОН, with 1.58 Wh/cell - ( 0.72 Wh/L x 2.2L ).
All the 320 cells will produce : 320cells х 2.2 L/h = ~700 L/h SОН .
Each cell will consume 1.58 Wh, or all the Lyzer’s 320 cells will consume ~500 Wh.
Or a Lyzer Container, sized 2х2х1m, comprised of 64 Lyzers, will consume : 64 х 500W = 32,000W = 32 kWh, for producing :
64 х 700 L/h SОH = 44,800 L/h SОH х 0.535 kg/1,000L = 23.97 kg of SOH : 9 = 2.6 kg of Н2 , or
2.6 : 64 = 0.04 kg of pure hydrogen per one Lyzer.
Or : with 32 kWh we’ll produce 2.6 kg Н2 x 12,100 L/kg H2 = 31,460 L/h Pure Hydrogen (Н2) .
Hydrogen Fuel Cells “Horizon” produce 5,000 W/h power with hydrogen flow rate of 65 L/min or 3,900 L/h. As we saw above, 64 Lyzers produce 31,460 L/h hydrogen, or we can feed 31,460 : 3,900 = 8 (eight) fuel cells, 5kW each, totally 40 kWh :
Or 31,460 L/h Н2 : 3 900L/h = 8 cells Horizon х 5kW = 40 kW total output.
With 32 kWh we’ll feed the 64 Lyzers for hydrogen’s production.
The rest 8 kWh of power is the net energy, which could be used in the household / small business for heating, etc. needs.
If there is no, or lower need of power for a given period of time (nighttime), the 8 kWh net power could be used for production of additional NET quantity of hydrogen, with additional 16 Lyzers 500W / 0.04 kg/h H2 each, or :
16 Lyzers х 0.04 kg/h = 0.640 kg/h net = 7,744 L/h net hydrogen.
The entire system could be schematically shown in the following diagram :
H2 could be put in use as a fuel in fuel cell-electric vehicles (FCEV) as Toyota Mirai, for example, or else, or could be sold.
Toyota Mirai drives a 500 km distance with two bottles of 2.5kg, 700-bar hydrogen.
Such a cylinder could be filled for about 8 hours with our 16 Lyzers.
This system produces also heat ( the outlet clean distilled water, getting out of the fuel cells, 40-50 deg.C hot, which could be used for heating premises and water) .
The system could be installed in a small container and delivered anywhere, for non-stop combined power, heat and fuel production, out of water, at a cost, close to zero.
It can be also scaled up into limitless-large, industrial, megawatt-scale plants.
COMPARISON H2 - SOLAR
H2 Plant 8kW net = 64 lyzers x 320 cells = 20,480 cells 125X60mm
Solar Plant 8kW net = 53 panels x 144 cells = 7,632 cells 125x60mm
----------------------------------------------
Solar Panel 150W, 1500x700x40mm = 1.5 x 0.7 x 0.04m = 0.04m3/panel
--------------------------------------
SOH Lyzer 125W, 500x250x250mm (0.5 x 0.25 x 0.25m) = 0.03m3/lyzer
