Hydrogen

Hydrogen supply and applicationsHydrogen is
the link between renewables and transport
Intermittent renewable power will eventually
require the grid to store energy. Hydrogen will
be an attractive pathway
Renewables
Electrolysers
Hydrogen gas store
Power regeneration
Hydrogen powered transport will be an important
part of the future

SupplyBrown hydrogen will help build the case
for green hydrogen

• Presently, hydrogen is used as a chemical and is
  commonly produced in large quantities
• Highly efficient and cost effective process
• Relatively simple process
• Relatively inflexible
• In the future, hydrogen produced by electrolysis
  is a way of capturing energy from excess
  renewables

Finally when the energy is released the only
bi-product is water
CH4 H2O CO 3H2

cylindersHydrogen infrastructure is not a
barrier to start the process

Improving how the public perceive the risks of
hydrogen is our top issue

• Hydrogen is a safe gas when engineered correctly
• Its properties are
• Defuses readily
• Extremely flammable
• Gas at atmospheric temperature and pressure
• Colourless
• Odourless
• Tasteless
• Smallest molecule
• Lightest specific density (14 times lighter than
  air)
• Non-toxic, simple asphyxiant
• Non-corrosive
• Metallurgical hydrogen embrittlement
• Normal boiling point -253 C
