In response to my article on hydrogen fuel cells, one of my readers, John V. Ryan, has written a follow-up article about the comparison between Battery Electric Vehicles (BEV’s) and Hydrogen Fuel Cell Vehicles (HFCV’s). Hopefully, this inspires others to do the same, so we can build this site into a platform where everybody can write or blog about their view on the automotive industry. Thanks John! Bart.
Hydrogen Fuel Cell Vehicles compared to EV’s
Regarding automobiles, it appears Battery Electric Vehicles (BEV’s) are superior at this time to Hydrogen Fuel Cell Vehicles (HFCV’s), and will remain so for the foreseeable future, for three reasons:
- HFCV’s offer less than 1/3 the efficiency of BEV’s.
- Mobile hydrogen fuel cells (HFC’s) are not yet even being manufactured, let alone near reaching economies of scale. In contrast, mobile Li-ion batteries are well-developed and dropping in cost: they have become 40 to 50% cheaper in the past two years alone – and many private and public groups are working intensely to create even better mobile batteries.
- Creation of the hydrogen refueling infrastructure will be epic, and cost many billions of dollars. Meanwhile, electricity is available everywhere, and, happily, BEV’s mostly recharge during off-peak hours, utilizing power that would otherwise be wasted. Where required, electrical grid capacity upgrades are relatively inexpensive, and easily accommodated. Even better, within a smart grid, BEV’s add the benefit of becoming dynamic storage devices, allowing the electrical utility to “borrow” power from them at peak times, and then pay it back at off-peak times.
