Charged EVs | Freight professional David Cebon on electrical vs hydrogen

David Cebon is a Cambridge professor who has devoted many years to move analysis, and the present Director of the Centre for Sustainable Highway Freight. In a current interview for Einride, a Swedish supplier of autonomous electrical vans, Cebon mentioned his analysis into the professionals and cons of hydrogen gasoline cell automobiles versus battery-electric automobiles for highway freight.

“The capital price of a hydrogen-powered car is about double the capital price of a battery electrical car,” Cebon instructed Einride. “And I do know that as a result of I’ve tried shopping for them for analysis functions. There’s a very good cause why it’s costlier: a hydrogen gasoline cell truck is a battery electrical truck with the gasoline cell added on. They each have an electrical motor, an electrical drivetrain, a battery, inverter and so forth. The electrical truck simply has a much bigger battery, that’s all. So as an alternative of getting larger batteries, a hydrogen-powered truck has hydrogen gasoline cells, hydrogen tanks and hydrogen supply tools. And people issues are all very sophisticated and really costly.”

Hydrogen followers usually cite BEVs’ shorter vary and longer charging instances, however generally ignore the truth that battery know-how is frequently enhancing. “We’re all very keen on studying curves, of how know-how goes to get cheaper with time,” says Cebon. “Batteries are going to get cheaper, but it surely received’t be due to the trucking business—will probably be due to the automotive business, which makes use of a minimum of 5 instances extra batteries. The know-how and studying curves are being pushed by the automotive business, not by the truck business. In case you take a look at the identical drawback with the hydrogen gasoline cell car, nicely, there are a thousand instances extra electrical vehicles being made yearly now than hydrogen gasoline vehicles. Hydrogen gasoline cells will not be going to be getting cheaper, as a result of hydrogen vehicles will not be going to be a factor. So, if hydrogen-powered vans are at present twice as costly as battery-electric vans, that hole might be going to widen.”

Cebon additionally notes the superior effectivity of BEVs. “In case you do these somewhat easy calculations, you’ll be able to work out that to run a truck on inexperienced hydrogen, you want about 3 times extra electrical energy than it’s good to energy a battery-electric car. 3 times extra electrical energy means you want 3 times extra wind generators, 3 times extra photo voltaic panels or nuclear energy stations. And, with that, you want 3 times extra upkeep, 3 times extra spare elements. No matter you’ve, it’s going to price 3 times extra to run hydrogen-powered automobiles than to run electrical automobiles. So, 3 times extra on working prices, two instances extra on capital prices, you’d should be insane to purchase a hydrogen-powered truck, proper?”

However what if an electrical truck couldn’t do the work wanted for a selected use case? “Is it attainable to run logistics with an electrical truck? The reply is sure, it’s. Within the UK, we’ve analysed heaps and many operations, they usually can all be carried out with electrical vans with charging in relaxation breaks and notably at warehouses.”
