Comments on: ‘Absurd’ Genoa bridge collapse triggers nationalisation row EU news and policy debates across languages Tue, 28 Aug 2018 13:03:07 +0000 hourly 1 By: Tue, 28 Aug 2018 09:30:44 +0000 One of the problems that is going to be faced by infrastructure all over Europe is that considering the ‘NGO’ Transport & Environments’ policies regarding the decarbonisation of trucks; ie try to get as many battery-powered trucks on the roads as possible; this is going to mean that bridge collapses such as the one in Genoa are going to be commonplace.

The issue with battery-powered long haul transport is that the weight of the vehicle is over 2.5 times that of an average truck, and for only half the overall range (at best); and in fact despite the rather vague plans described by T&E for battery trucking; we all know this is very unlikely to happen. Whatever progress is made with batteries and trucking it is unlikely to become a widespread phenomena, for a number of reasons as described by a recent Canadian report:

“Negatives such as lengthy charging times, the weight of batteries, and an inability to travel long distances, were reasons fully electric trucks were not seen by CESAR as being the best option for Canada as a whole.

Advertising a 475-800-km range fully loaded, Lof said if the Semi were to achieve this mark, it would need a 1.6 megawatt battery, which would weigh around 16,000 lbs., taking away from the amount of freight the Semi could haul.

The Tesla Semi is anticipated to weight around 37,000 lbs., while a traditional diesel truck tips the scale at about 17,000 lbs.

Charging time is another issue with battery -powered trucks. Even with a fast charger, which knocks the time down to around five to six hours, time is an issue compared to how long it takes to refuel a diesel truck.

Pouliot also pointed out that fast charging is hard on a lithium battery, and can decrease its lifecycle, adding to the overall cost of the investment.”
