I’ve written my own debunking of the legitimacy of hydrogen fuel cell cars. Battery electric cars will always be better in every way given the speed of technological developments past, present and future.Even though a HFC-powered car is essentially an electric car, you get none of the benefits like filling it up with your own power source, using it as a smart grid buffer, regenerating energy during braking, etc.Efficient HFCs have very slow response times, meaning you again need additional systems to store energy for accelerating.Easy ways to get large quantities of hydrogen are not ‘cleaner’ than gasoline.It has a horrible well-to-wheel efficiency as a result. Hydrogen is actually pretty hard to make.There won’t be for at least 20 or 30 years, even if we start building it like crazy today. There is no infrastructure for distributing or even making hydrogen in large quantities.HFCs require a shit ton of supporting systems, making them much more complicated and prone to failure than combustion or electric engines.Hydrogen storage is inefficient, energetically, volumetrically and with respect to weight.Hydrogen fuel cells have bad theoretical and practical efficiency.Hydrogen as a fuel is incredibly hard to make and distribute with acceptably low losses.Fuel cells wear out crazy fast and are hard to regenerate.

Hydrogen as a fuel is perceived to be a relatively small infrastructural change from gasoline and diesel.Hydrogen fuel cells are thought not to wear out as quickly as batteries (or conversely, batteries are thought to wear out very quickly).The mileage you can get out of hydrogen is perceived to be more adequate than what you get from batteries.You can still fill up like you do with a gasoline or diesel powered car.

These key points are laid out in bullet points at the beginning of Part 1, Part 2, and Part 3:įirst of all, HFC cars are perceived to be a good bridge between fossil fuels and full electric because: Admittedly, it would be nice if the author updated it to match the current market - it was published in February 2015 and is dated in a couple of parts.īut the key points are the same nonetheless, and they aren’t changing. It is a long piece, and it’s in three parts. This is not our recent piece on hydrogen as fuel/energy carrier.
