Belgium: De Lijn relies on plug-in hybrid buses with extended capacity

@ VDL / De Lijn

De Lijn, the public transport operator in the Flemish part of Belgium, has made an important step towards the emission-free servicing of urban areas. The Board of Directors approved the order of 44 new articulated plug-in e-hybrid buses and confirmed the upgrade of 280 hybrid buses into e-hybrids – the determination used for hybridbuses with additional battery capacity. Their extended zero-emission range will contribute significantly towards improving air quality in the cities these buses will service. “By deploying these buses, De Lijn comes even closer to zero emission in urban areas, with the final goal of emission-free service in the whole of Flanders”, says Lydia Peeters, Flemish minister of Mobility and Public Works. Ever since the new Flemish government took office in 2019, Peeters has been working hard towards a zero-emission fleet for De Lijn. To that effect, Peeters has allocated € 93 million of her EU COVID recovery budget towards a greener fleet for De Lijn, mainly for electric buses and their charging infrastructure.

De Lijn’s first hybrid buses were introduced in its fleet in 2009 – it currently consists of 530 hybrid buses. “The main advantage of e-hybrid buses over regular hybrids lays in their battery capacity,” Peeters explains. “With regular hybrids, that capacity is limited: while they accelerate emission-free from standstill, their low-emission diesel engine kicks in after about 400 m to recharge their battery pack. With e-hybrids, their battery capacity is expanded, so that they can drive fully electric for an uninterrupted 15 to 100 km.”

Green electricity

The De Lijn Board decision means that the operator will have 150 e-hybrids with a 15 km electric range, 90 e-hybrids with an e-range of 30 km and 84 articulated e-hybrids with a 100 km uninterrupted electric range. By preference, the battery packs of these e-hybrid buses will be charged at their depots – this will happen at night and during the day, when the e-hybrids return for short periods. The main reason is that De Lijn strictly purchases green electrify only. The batteries may also be recharged outside of urban areas while the buses are en route via their low-emission EUR6 diesel engines that have DPF filters. This will enable the e-hybrids to drive several emission-free cycles per day.

Minister Peeters: “The Flemish region of Belgium invests heavily in sustainable transport. This announcement is yet another contribution towards meeting climate change targets. This is a first but important step to implement zero-emission traffic in the whole of Flanders in general and in its urban areas in particular. The EU’s recovery assistance will enable us to accelerate the introduction of emission-free buses into the De Lijn fleet. In practice, the support means that our 324 e-hybrids will be able to drive longer distances within urban areas without any emission, which in turn will improve air quality in the most densely populated urban areas.”

De Lijn’s approach of a wide-ranging use of hybrid buses with additional battery capacity is closely followed by its European counterparts and by the UITP, the International Association of Public Transport.

De Lijn had some zero emission buses in Ghent some time ago. They were replaced with diesel buses. The infrastructure for these buses remained in place until quite recently.
