The transport industry is responsible for about 15 % of total greenhouse gas emissions. Heavy transport and maritime transport in particular account for 10 % of global carbon emissions. With a growing awareness of climate change and sustainability, decarbonising these sectors has become a priority. However, the electrification of these transport vehicles faces major challenges due to the long distances they have to travel and the heavy loads they carry.  Here, renewable hydrogen emerges as a promising alternative due to its high energy density compared to batteries.Figure 1.
