Hydrogen Compression

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

• 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]

Hydrogen Engines

Fuel Cells

• Fuel cell types overview - [13]
• 1kW costs $5k - [14]
• 400W for 8k Euro [15]
• $60/W - [16]
• 11k fuel cell cars exist already worldwide, half of them being in California - [17]
• From [18] -

Efficiency and Lifetime

• Efficiency from electrolysis back to electricity in fuel cells is 45% with fuel cells - p. 11 - [19]
• Lifetime of PEM FC is only 2k-4k hours in cars, and 40k in stationary applications. Major issues with longevity! [20]
