Beware Hydrogen does not necessarily mean HFC. There's green hydrogen and there's real green hydrogen. Beware, for big oil some forms of hydrogen are really just hydrocarbons by the back door. True green hydrogen is produced exclsuively from non-fossil electricity generation (ie wind/hydro/solar/pumped storage). The amount of energy it takes to produce hydrogen is massive and today mainly oil based, and the distribution costs are not alone high, but relay on fossil distribution, while every home already has a 3pin socket connected to the electricity grid which is the most efficient and economically viable energy distribution method. IMHO HFCEV tech may have a large role to play in HGVs, heavy agri, heavy construction and Hydrogen a role in grid storage and grid peaking, but doesn't make the cut for personal mobility (ie car transport). Today there are only 5 H pumps in the entire UK, and zero in Ireland, but the electricity grid in both countries already exists to every home. Ireland is ideally positioned to have a 100% green grid within 10 years (ie true green rather than green washed), and so rail transport could switch to electric. EU won't allow diesel much longer anyway. Hydrogen ICE is still combustion and generates CO2, its cleaner but no where near as clean nor efficient as our electric. Hydrogen ICE still means high maintenance costs and oil lubes, as it's basically still a mechanical combustion engine. A 201 has been trailed with this, an improvement over straight diesel with its fifty NoX emissions, but its still combustion and emits CO2. Have we run out of time for gradual managed transition?
