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

Demonstration Hydrogen Houses

  • Hopewell Project - NJ - [7]. AKA Hydrogen House - [8]
  • Scientific American - Oh, only $500k for the off-grid home - [9]

Hydrogen Engines

Fuel Cells

  • Fuel cell types overview - [11]
  • 1kW costs $5k - [12]
  • 400W for 8.5k Euro [13]
  • $60/W - [14]
  • 11k fuel cell cars exist already worldwide, half of them being in California - [15]
  • From [16] - Fccars.png

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]

Fueling Stations

  • Cost approximately $1M each. OSE could fund these from proceeds of programmatic revenue in locations of OSE Campuses.
