OSE Position
OSE proposes a robust economy based on water lubricated internal combustion engines running on hydrogen as an immediate term feasible solution for power production.
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
- 200 cc/min at 3-8 bar - $9k - [7]. 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. [8]
- Redo the same - and 10x lower cost.
- Need 3 hours of Honda EU1000 generator - or 2.7 kWhr.
Demonstration Hydrogen Houses
- Hopewell Project - NJ - [9]. AKA Hydrogen House - [10]
- Scientific American - Oh, only $500k for the off-grid home - [11]

Fuel Cells
Efficiency and Lifetime
- Efficiency from electrolysis back to electricity in fuel cells is 45% with fuel cells - p. 11 - [17]
- Lifetime of PEM FC is only 2k-4k hours in cars, and 40k in stationary applications. Major issues with longevity! [18]
