What is Hydrogen?

• Gas
• Found everywhere
• Found in water

Production of Hydrogen

• Steam reforming
• Electrolysis
• 1800 English scientists William
• Nicholson and Sir Anthony Carlisle
• Gasification

In Recent History

• Very new technology commercially
• Result of fossil fuel limitability
• Under production
• Requires a new field of economy

Outlook on Production

• Natural Gases
• From Coal
• Nuclear Power
• Renewable Resources

Complications

• Hard to store
• Conversion to usable Hydrogen
• Cost
• Distribution

Safety Hazards

• .

• .

• Hydrogen has the widest explosive/ignition mix
  range with air of all the gases except acetylene.
  That means that whatever the mix proportion
  between air and hydrogen, a hydrogen leak will
  lead to an explosion, not a mere flame.

16
Solutions to Problems

• Hydrogen transport vehicles
• Fuel Cell Infrastructure
• New Thermodynamically efficient Technologies
• US DOE Hydrogen, Fuel Cells Intrastructure
  Technologies Program

Effects on the Environment

• Emissions of CO2
• Electrolysis of water
• Fossil fuel reforming
• By-products of hydrogen-nitrogen reactions in
  internal combustion engines
• Leaked Hydrogen can become catalyst for ozone
  depletion
• Wikipedia article on hydrogen economy

19
Laws and Regulations

• Flame detectors must be used
• -Implementation of higher standards to detect
  early leaks
• -Standard for the installation of stationary
  fuel cell power systems (Wiki)
• - Codes and standards have been a major barrier
  to deploying hydrogen technologies and developing
  a hydrogen economy
• -DOE is currently in the process of devising
  safety codes, standards and regulations

20
Sustainability

• Hydrogen can be produced in a variety of ways
• -Most efficient way is by electrolysis of water
• -Water can be recycled and used for drinking
• -Overall sustainable as it is the most abundant
  element in the universe

21
Efficiency

• Hydrogen is an energy carrier, not a source
• Relies on the use of other fuels to be used
• Overall use of energy to create outweighs energy
  production
