The Role of Hydrogen in a Sustainable Energy System

Gert Jan Kramer, Shell Global Solutions, Amsterdam

Hydrogen is a good candidate "energy vector" for a sustainable world. 
(This statement does not critically depend on the definition of sustainability).
Other such vectors are electricity and biomass, or biofuels. Even en route to 
such a sustainable world, hydrogen can already contribute to sustainability, 
more specifically to CO2 mitigation, when it is as a low- or zero-carbon made 
from fossil fuels in combination with carbon sequestration. 

In my lecture, I will critically discuss all the technical options that exist 
to make hydrogen, as well as the availability of the energy resources from 
which to make it (fossil, nuclear, renewable), and from this try to indicate 
their relevance in the short, medium and long term, by using Shell's long-term 
energy scenarios.
