Frans Verbruggen and I determined that you save a whopping 3t if you redesign your truck with electric motors close to or in the wheels.

And I cheered on the @transenv initiative that got zero emission trucks a and others to implement an extra weight allowance of 2 tonnes in the EU. So electric trucks in the EU can carry a 5 tonnes battery without losing cargo. Their max cargo capacity is just 1t less!
From our Port of Rotterdam statistics we could see that most trucks don't need max capacity. Don't believe me: believe this trucker: https://www.quora.com/How-much-does-the-average-big-rig-truck-weigh
So really: battery weight is not a long term problem for electric trucks and it can get you the cheapest energy/km.

This is important: 40t trucks cause the most CO2 emissions of all freight transport types.
If we electrify them we also use batteries to maximum effect because these trucks save an unparalleled amount of CO2 (and money!) per kWh of battery.

This slide regularly pops up in my timeline now. https://twitter.com/RECESS_CA/status/1250188310518976513?s=20 Errors imho:
Not aware of the 3t (6600 lbs) drivetrain advantage.
Battery 8.5 kg/kWh instead of the 6 kg/kWh that I got by basing it on current battery tech.
Energy use 1.6 kWh/km is non-optimized truck.

Also nice to mention: @M_Steinbuch and I have now supervised 3 master students on electric trucks. I just don't get around to writing it all up properly.
Wow, @foroelectricos just wrote an article about this thread in SPANISH. I've often thought that it would be great to write not just Dutch and English but also Spanish, French and German. So I'm really glad about this. https://forococheselectricos.com/2020/05/los-camiones-electricos-a-bateria-seran-los-encargados-de-sustituir-a-los-diesel-no-los-de-hidrogeno.html
