Hydrogen (H2) presents a significant opportunity for modern energy systems. These systems are amid the decarbonization transition due to public concerns about greenhouse gas (GHG) emissions, rapid technical innovation, the availability of specific energy resources, and the growing population from developing nations emerging from energy poverty (Saundry, 2021a). High-carbon energy sources and carriers need to be replaced by low-carbon ones to handle the growing energy demand during the current energy transition (Corbeau et al., 2022). While H2 is not a panacea for this transition, it "uniquely complements and enables other decarbonization pathways such as direct electrification, energy efficiency measures, and biomass-based fuels” (Hydrogen Council, 2021, p.13). In other words, H2 may assist other low-carbon technologies and energy efficiency improvements to achieve favorable decarbonization outcomes.
