Comparison of hydrogen production systems in terms of carbon footprint

As presented in the European Hydrogen Strategy recently launched by the European Commission, hydrogen is bound to play a major role in the decarbonisation of the energy system. In this sense, given the wide range of hydrogen production pathways, their sound comparison in terms of carbon footprint is of paramount importance. To that end, Life Cycle Assessment is the most well-established methodology. The Systems Analysis Unit of IMDEA Energy has a large experience developing and applying LCA solutions specific to hydrogen energy systems, e.g. tools and libraries for the robust comparison of reference environmental indicators (including carbon footprint) for a large number of hydrogen options. Beyond this initiative, this work* authored by the Systems Analysis Unit of IMDEA Energy deals with the enhancement of the carbon footprint comparison of four hydrogen options by appropriately considering the expected evolution of key technical parameters (efficiencies, lifespans, and grid electricity mix) under three time scenarios (reference, year 2030, and year 2050).
