2. Hydrogen is the most abundant element in the universe. In its purest form, hydrogen is a non-
toxic colorless and odorless gas.
Hydrogen (when used as a fuel ) like electricity, is an energy carrier rather than an energy
resource.
Hydrogen and electricity can be generated from greenhouse gas-neutral sources, addressing
climate change and urban air quality problems.
As with electricity, hydrogen can also be produced from sustainable domestic and renewable
energy resources, such as wind or solar-powered electrolysis, which enhance our long term
energy security.

8. Process
Methane pyrolysis is done by decarbonizing natural gas.
It splits methane into hydrogen and carbon using high
temperature by moving it through a mixture of molten salt.
This allows for 60% of the energy in natural gas to be used without
generating any CO2 emissions - a process which has the potential
to decarbonize more than 25% of the worldโs energy.
Although hydrogen accounts for 60% of the energy in natural gas,
it comprises just 25% of the mass with the remainder being solid
carbon.
9. Contd.
๏ต So there is no need to invest in
carbon capture facilities and no
need to worry about where to store
it.
๏ต These process uses electricity to
provide the industrial heat needed
and this could be met entirely by
renewable sources.
๏ต This makes methane pyrolysis a
particularly suited to countries with
both large natural gas reserves and
good access to renewable energy.
