OSE Position
OSE proposes a robust economy based on water lubricated internal combustion engines running on hydrogen as a solution for distributed power production - available today using current technology with no new innovation needed outside of social innovation towards acceptance of the possibility.
Info
- Hydrogen Station Compression and Costs from NREL - [1]. Concludes cost of compression, storage, and
- Diaphragm compressor - for hydrogen - [2]
- Piston compressors provide high volume. Easier to do than diaphragm compressors. No need for ultra purity in hydrogen engines. [3]
Low Pressure Storage
- Low pressure hydrogen storage - [4] - NJ demo house.
Companies
- Pure Energy Centre - [5]
Hydrogen Cylinders
- 2000 PSI - 194 cu f (5.5 cu m) [6]
Hydrogen Generator
Separating Generator
- Diagram of system - [7]. Paper has info contacts at NREL, and comparison of PEM to alkaline.
- alkaline electrolyzer stack - price not shown - [8]
- 200 cc/min at 3-8 bar - $9k - [9]. With 1440 minutes/day - or 0.3 cu meter per day.
- 1000 cc/min - $3280 - for 1000 ml/min - 1.4 cu meter/day. Alkaline, 4 bar. That is 130 grams of hydrogen per day. [10]
- Redo the same - and 10x lower cost.
- Need 3 hours of Honda EU1000 generator - or 2.7 kWhr.
- 500 cc/min - $700 - [11]
- Zirfon PERL is common electrolyzer separator material - [12]. It is a polysulfone (3D printable) and 85% ZrO2 nanoparticles blend. ZrO2 - [13]
- Both stainless steel and nickel work as electrodes - [14]

Mixing Generator
- $200 for 6 lpm - but this is HHO, not H + 0
- Graphite plates work well - [16]
- Wet vs dry cell design - [17]
Demonstration Hydrogen Houses
- Hopewell Project - NJ - [18]. AKA Hydrogen House - [19]
- Scientific American - Oh, only $500k for the off-grid home - [20]

Fuel Cells
- Fuel cell types overview - [22]
- 1kW costs $5k - [23]
- 400W for 8k Euro [24]
- $60/W - [25]
- 11k fuel cell cars exist already worldwide, half of them being in California - [26]
- From [27] -
Efficiency and Lifetime
- Efficiency from electrolysis back to electricity in fuel cells is 45% with fuel cells - p. 11 - [28]
- Lifetime of PEM FC is only 2k-4k hours in cars, and 40k in stationary applications. Major issues with longevity! [29]
Fueling Stations
- Cost approximately $1M each. OSE could fund these from proceeds of programmatic revenue in locations of OSE Campuses.
