The production and use of hydrogen only makes sense if the production and transportation is carried out with minimal impact on natural resources, and if greenhouse gas emissions are reduced in comparison to conventional hydrogen or conventional fuels. This is particularly relevant for transportation applications, where greenhouse gas emission reduction is an immediate challenge. As presented in Figure 1, the study “A portfolio of power-trains for Europe: a fact-based analysis”, released in October 2010, illustrates the necessity of a progressive introduction of green hydrogen production from 2015, accelerated towards 2020 mostly through large scale production, which should lead to CO2 lean hydrogen availability at the point of use.

Green hydrogen production is also extremely relevant for industrial uses to enable more sustainable processes such as in petroleum refining processes, biodiesel production, chemical and metallurgical industries, or electronics. European public policies such as the European Fuel Quality Directive and the Renewable Energy Directive implicitly also trigger the need to accelerate the development and industrialisation of cost effective green hydrogen.
