DHL Freight Sweden and Denmark-based Green Energy Group have announced a nationwide one-year pilot in Sweden to test the use of vehicle-integrated PV with a fleet of biofuel-powered transport trucks.
To measure how solar energy improves the efficiency of biofuels, Danish startup Green Energy Group is supplying its vehicle-integrated PV systems (VIPV) to DHL Freight Sweden for use in ten vehicles in a twelve-month pilot project.
Based in Sweden, the project includes ten vehicles from Scania and Volvo, powered by hydrogen-treated vegetable oil (HVO) and liquefied biogas (LBG). Four of the HVO and four of the LBG vehicles are equipped with 240W solar systems based on Green Energy Group’s glass-free copper-indium-gallium-selenide (CIGS) panels, and the two LBG trucks are equipped with 320W systems.
They will operate nationwide, from Luleå to Skåne, with the VIPV units powering onboard systems such as refrigeration units and tailgates to reduce alternator load, fuel consumption and CO2 emissions.
They are all connected to a charging controller and tracking software from Green Energy Group to measure fleet performance and collect real-time operational data.
“We are excited to measure the impact of solar energy on improving the fuel efficiency and reliability of DHL’s alternative fuel trucks,” said Anders Mikkelsen, Strategic Sales Manager of Green Energy, in a statement.
Founded in 2015, Green Energy Group has established itself as a VIPV supplier for commercial diesel fleets. Its installed base is international and includes Denmark-based Arla and DFDS, Sweden-based Postnord, Czech Republic-based MD Logistika and Germany-based FlixBus
It offers a range of CIGS panels tailor-made for heavy-duty transport applications, with fire, weather and impact resistant properties. It also supplies the necessary charge controllers, cabling and batteries.
DHL Freight Sweden’s efforts to reduce greenhouse gas emissions through the use of electric vehicles and biofuels in its transportation network are ongoing. “Green Energy’s ultra-thin and durable solar panels have already demonstrated high performance in extreme weather conditions. This gives us confidence that they will withstand the varied Swedish climate and deliver measurable benefits to our fleet,” said Ylva Öhrnell, Sustainability Manager, DHL Freight Sweden, in a statement.
