To meet the European Green Deal, new CO2 emission standards for Heavy-Duty-Vehicles (HDV) have been set. The amended Regulation EU-2019/1242 has a wider scope, covering not only lorries but also trailers. From 2030 on (semi-)trailers must reduce their emissions by 10%, even though trailers generally do not emit any CO2-emissions. But how can a trailer save CO2?
To calculate emissions, the European Commission has developed VECTO, the Vehicle Energy Consumption Calculation TOol. It is a standardized framework designed to determine fuel consumption and CO2-emissions of HDVs. Analysis show that the two main focus points for CO2 reduction, based on VECTO, are weight reduction and improved aerodynamics. However, equipping trailers with aerodynamic devices or making them lighter isn’t straightforward. Trailers lead a rough life and the industry is adapted to the current trailer designs. Lightweight constructions might harm the lifetime of a trailer and trailers with protruding aerodynamic parts won’t fit on a train anymore. Besides, both solutions have a major influence on the vehicle (roll-over) stability and therefore safety. It is not that evident for a trailer manufacturer to design a (new) trailer that 1) fulfills the CO2 regulations, 2) complies with the constructional requirements and 3) remains safe and stable.
This 3-step-approach is really missing for trailer manufacturers, and this is endorsed by Burgers Carrosserie: “How can we validate (upfront) that the trailer is still as “strong” and “safe” if we apply the weight reduction that shows sufficient CO2 saving in VECTO?”. The answer was simple, it isn’t.
It is the aim of Trenergy to develop this 3-step approach with complementary simulation tools, where trailer manufacturers can validate their design(s) for CO2 Savings, Construction and Safety. It is intended to make the developed models/tools open source for the Logistic Industry.
