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.
Steam Reforming. Electrolysis. Reaction of acids on metals. Hydrogenation of unsaturated substrates. Reducing equivalents in biochemical reactions. Recent research : Aluminium and Gallium Alloy.
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
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
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.
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 its needed. Toyota FCHV PEM FC fuel cell vehicle.
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.
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),
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. Honda FCX Clarity, a hydrogen fuel cell demonstration vehicle introduced in 2008

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
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,
