The Rise of the Hydrogen Electric Car

Lack of charging infrastructure

The race is on for car manufacturers to bring out their own range on electric vehicles (EV). But what if the new kid on the block ends up taking over? Honda, Hyundai, and Toyota are among the major firms now testing out hydrogen fuel cell electric vehicles (FCEVs) in their production lines to see which proves the most successful.

FCEVs have been criticized for being less efficient as only around 55 percent of the hydrogen energy created through electrolysis is usable, compared to between 70 and 80 percent in battery-electric cars. However, there are several advantages to fuel cells, including low recharge times – just a matter of minutes, and long-range. But several practical obstacles stand in the way of hydrogen FCEVs, such as the lack of charging infrastructure in contrast to the ever-expanding EV infrastructure. For example, at the beginning of 2021 there were only 12 hydrogen fuelling stations in the U.K., not surprising as only two brands of FCEV were on the market – the Toyota Mirai and the Hyundai Nexo.

In addition, hydrogen is currently much more expensive than electric fuel, costing around £60 for a 300-mile tank. Moreover, much of the hydrogen on the market comes from the excess carbon produced from fossil fuels by using carbon capture and storage (CCS) technologies. Yet, the disadvantages of battery EVs should not be overlooked. After years of investment, it is unlikely that we will see major advances in battery technology any time soon. Not to forget that lithium-ion batteries are heavy, making them near-impossible to use in freight and aviation. The metals used in existing battery production, such as cobalt and nickel, are also problematic due to ethical mining concerns as well a high costs adding to the overall price of EVs.
