In part 1 of our Hydrogen Series, the great variety of hydrogen production routes and technologies were presented and compared based on their maturity and performances. Around the world and particularly in developed countries such as the EU, there is a strong support for the development of hydrogen produced by water-electrolysis and powered by renewable electricity as it is one of the most mature and clean hydrogen production routes. This second part is dedicated to the analysis and comparison of 2030 EU’s targets in terms of renewable hydrogen production with the pipeline of projects. It will also explore the possibility of using other low-carbon hydrogen production technologies than water electrolysis.
