From Concept to Series

• The BMW Hydrogen 7 has undergone a complete
  series development process, similar to the
  process used to develop all series vehicles.
• The Hydrogen 7 is fully TUV approved in Europe
  and could be sold to customers IF hydrogen was
  available.

Why the internal combustion engine?

• The ICEs untapped potential of efficiencies and
  power
• Bi-Fuel capability a stepping stone to a full
  LH2 infrastructure
• A high level of dependability and versatility
• Better performance in low and high temperature
  regions
• Competitive costs of production and service
• Current production facilities can be utilized
  with little adaptation
• Moderate plant investment
• Dynamic driving experience, especially at highway
  speeds and in typical driving situations
• Over 25 years of experience with LH2 ICE engines
• BMW typical driving characteristicsno
  compromises necessary

11
Why Liquid Hydrogen instead of Compressed Gas
Hydrogen?

• Liquid hydrogen is easily transported and stored
  for refueling.
• Cryogenic liquid hydrogen storage systems allow
  for longer driving range
• Thermal storage performance of LH2 storage
  systems can be even further developed to minimize
  boil-off losses.
• The design for mass production approach
  promises considerable reduction in complexity and
  cost.
