2.  Hydrogen is the simplest element.
 Most plentiful element in the Universe.
 Colourless gas with purple glow in its plasma state.
 Doesn’t occur as gas naturally.
 Hydrogen is found in many organic compounds.
 Hydrogen is high in energy.
 Clean and Sustainable option for powering our future.
 Has the potential to replace harmful emitters like
conventional fossil fuels.

3.  Steam Reforming.
 Electrolysis.
 Reaction of acids on metals.
 Hydrogenation of unsaturated substrates.
 Reducing equivalents in biochemical reactions.
 Recent research : Aluminium and Gallium
Alloy.

4.  Hydrogen energy is can be produced by
creating a reaction between hydrogen
and oxygen.
 Hydrogen can be stored to produce
electricity
 Continuous Power Supply
“If consumption trends continue, worldwide consumption of
crude oil will increase by over forty percent by 2025”
- Report in Futurist magazine

5.  Hydrogen is secondary carrier just as electricity.
 Involves five basic issues
 Production
 Storage and Transport
 Usage of Hydrogen as Energy Resource
 Safety
 Economics and Management

6.  Hydrogen fuel cells are an electrochemical energy
conversion tools.
 A fuel cell combines hydrogen and oxygen to produce
 Electricity,
 Heat and
 Water
 Fuel cells differ from batteries.
 Fuel cells are a promising technology
 Source of heat and electricity for buildings.

7.  Electrical power source for electric motors propelling vehicles.
 Fuel cells operate best on pure hydrogen.
 Some fuel cells even can be fuelled directly.
 In the future, hydrogen could also join electricity as an important energy
carrier.
 Hydrogen can also be transported.
 For example:
We can produce electric energy and hydrogen, and stored it until it's needed.

fuel cell vehicle.

8.  AREVA track record: Distributed energy storage solution on
MYRTE platform, University of Corsica site in Ajaccio, France.
 The world largest hydrogen-based energy management system
coupled to a photovoltaic field.

9.  The RS-25, otherwise known as the Space
Shuttle Main Engine (SSME), is a liquid-
fuel cryogenic rocket engine.
 RS-25 burns cryogenic (liquid
hydrogen & liquid oxygen) propellants, with
each engine producing 1,859 kN (418,000 lbf)
of thrust at lift off.
 The RS-25 operates at extreme temperatures,
 The liquid hydrogen fuel stored at −250
C (−418 F)
 The temperature in the combustion
chamber reaches 3,315 C (6,000 F),

10.  Onboard fuel for motive power.
 Chemical energy of hydrogen to mechanical energy.
 Not an energy source, but is an energy carrier.
 No Carbon dioxide emission.
 Produces only nitrogen oxides (NOx) when burned in ICEs.

demonstration vehicle introduced in 2008

11.  Automobiles.
 Buses.
 Bicycles.
Bicycles
 Motorcycles & scooters.
 Airplanes
 Quads and tractors.
Automobiles
 Fork trucks. Sequel, a fuel cell-
powered vehicle
 Rockets.

12.  The large investment in infrastructure would be required
 To fuel vehicles, and
 The inefficiency of production processes.
 Typical hydrogen fuel cell is also very expensive to
produce.
 The efficiency of hydrogen fuel cells depends largely
upon how much power is taken from it.
Power Taken Out ∝ 1
Efficiency

13.  Low energy content per unit volume,
 High tank weights,
 Very high storage vessel pressures,
 The storage,
 Transportation and
 Filling of gaseous or liquid hydrogen in vehicles,
