With the looming threat of climate change, we are to sustain a push towards the electrification of our energy grids. Hydrogen stands as a strong contender to mitigate the geographical imbalance and intermittency of renewable energy sources. Hydrogen produced from renewable energy sourced, dubbed 'Green Hydrogen' stands to be more affordable than Grey Hydrogen (typically produced from fossil fuels) . This has led to various global policies supporting the development of a wider hydrogen economy , , . The global fuel cell market is projected to grow at a Compounded Annual Growth Rate (CAGR) of 15 % -from $ 3.74 billion (2023) to $ 8.64 billion (2030) . Advances in membrane technology and material processing have poised low temperature Proton Exchange Membrane Fuel Cells (PEMFCs) as the technology unicorn, with a market share of 57.3 %. PEMFCs are particularly attractive for use in Heavy-duty Electric Vehicles (HDEVs) due to their superior specific energy and refueling speed, over Li-ion batteries . Similarly, a case study evaluating the viability of zero emission powertrains for maritime vessels determined that large and endurance vessels especially benefit from the adoption of fuel cells, even outshining existing fossil fuel propelled powertrains .
