Abstract Low-carbon road freight transport is pivotal in mitigating global warming. Nonetheless, electrifying heavy-duty vehicles poses a tremendous challenge due to high technical requirements and cost competitiveness. Data on future truck costs are scarce uncertain, complicating assessments of the role zero-emission (ZET) technologies. Here we derive most likely developments for price setting ZET components by meta forecasting from more than 200 original sources. We find that primed...

Electric battery trucks (BETs) have the potential to significantly reduce emissions from heavy-duty vehicles. However, adopting BETs for long-haul operations depends on availability of sufficient charging infrastructure. In this study, we use a trip chain model assess requirements in Europe 2030. Our accounts truck driving regulations and different stop types. We find that number overnight chargers (50–100 kW) required is 4–5 times higher than megawatt (0.7–1.2 MW) needed support BET share...

Following the Paris Agreement, virtually all countries worldwide have committed themselves to undertaking efforts limit global warming 1.5 °C. Within European Union (EU), recent 'Fit for 55' policy package proposes ambitious greenhouse gas (GHG) mitigation policies sectors as part of EU's contribution limiting warming. Yet, it is unclear whether proposed are sufficient EU °C and remains an open problem how translate temperature targets into sector-specific emission budgets further policies....

Battery electric trucks (BETs) can dramatically reduce tail-pipe emissions from heavy-duty vehicles. However, their limited range necessitates frequent charging. Megawatt charging has been discussed as requirement and potential barrier for fast BET market diffusion. Here, we simulate all daily trips of 2,410 in Germany BETs with lowest power required. Assuming 450 – 700 km (2030 2050) range, the share vehicles replaceable by is higher than 90 %. Most events (>95 % night charging, >75 day...

Fuel economy regulation is a powerful instrument to reduce CO2 emissions of vehicles and has recently been extended heavy-duty vehicles. In Europe, truck manufacturers are required the newly sold by 30% until 2030 compared 2019/2020. Accordingly, several have announced introduction zero emission (ZEVs) such as battery electric or fuel cell trucks. However, sales shares trucks meet targets not analyzed in literature yet. Here, we derive share scenarios for Europe based on reduction options...

Abstract Globally, road freight accounts for 40% of the CO 2 emissions in transport sector, mainly from heavy-duty vehicles (HDVs). All major truck markets have introduced fuel efficiency regulations HDV, and more ambitious require introduction zero-emission which battery electric trucks (BEVs) are a promising candidate. However, frequent long-distance trips dense public high-power charging network if BEV to meet today's operating schedules logistics. Here, we develop model fast-charging...

Heavy-duty trucks account for 27% of the European greenhouse gas emissions in transport sector. To decarbonize road freight transport, Union plans to build a fast charging network trucks. This paper presents two scenarios, covering highways with stations at regular intervals every 50 or 100 km along most important highways. For each location, required number points 15% battery electric trucking is calculated individually using queueing theory. A third scenario takes into infrastructure...

While the electrification of passenger vehicles is in full swing, for decarbonization heavy-duty trucks still various challenges exist. Especially high energy consumption combination with daily driving ranges makes battery electric operation much more difficult than cars. Accordingly, a broad set different drivetrains discussed, inter alia hydrogen trucks, catenary hybrid and synthetic fuels. One main advantage direct use electricity efficiency. Still, heavy duty concepts do Here, we compare...
