Natural gas-based hydrogen costs around £12 per kilo at the moment so it’s likely that hydrogen produced with electricity from renewable sources would be prohibitively expensive, unless production costs can be lowered.  

Where do EV and FCEV emissions come from?

Now, in case you’re scratching your head as to why we’re insinuating that EVs or FCEVs generate any emissions at all, it’s important to remember that manufacturing an electric or hydrogen car actually produces far greater quantities of carbon dioxide than the equivalent ICE car. The ICCT says EVs, for example, tend to break even after an average of 17,000km (10,500 miles) of driving – making up for their higher emissions in the production phase with lower emissions in the use phase.

The lifetime emissions of EVs are improving. In 2021, the ICCT projected that electric cars would give off 24 per cent more carbon dioxide and equivalent gasses than they do today. This signifies how improvements in technology and decarbonisation of manufacturing are making electric cars an ever-greener proposition compared with ICE vehicles.

If you’re wondering, hybrid cars are projected to emit anything between 20 and 30 per cent fewer carbon dioxide equivalents than ICE cars over the course of their lives, with plug-in hybrids (PHEVs) being towards the top end of that scale. 

It’s worth pointing out that the ICCT utilises official manufacturer figures for its analysis, rather than real-life emissions data. This, combined with the fact that not all cars make it to 20 years old, means that figures for FCEVs and EVs may appear somewhat inflated. Nevertheless, this shouldn’t override the clear finding that both fuel types offer huge environmental and sustainability benefits compared with internal combustion powertrains.
