Road transport is recognized as having a negative impact on the environment. Policy has focused on replacement of the internal combustion engine (ICE) with less polluting forms of technology, including battery electric and fuel cell electric powertrains. However, progress is slow and both battery and fuel cell based vehicles face considerable commercialization challenges. To understand these challenges, a review of current electric battery and fuel cell electric technologies is presented. Based on this review, this paper proposes a battery electric vehicle (BEV) where components are sized to take into account the majority of user requirements, with the remainder catered for by a trailer-based demountable intelligent fuel cell range extender. The proposed design can extend the range by more than 50% for small BEVs and 25% for large BEVs (the extended range of vehicles over 250 miles), reducing cost and increasing efficiency for the BEV. It enables BEV manufacturers to design their vehicle battery for the most common journeys, decreases charging time to provide convenience and flexibility to the drivers. Adopting a rent and drop business model reduces the demand on the raw materials, bridging the gap in the amount of charging (refueling) stations, and extending the lifespan for the battery pack.

Urban Freight Transport

The environmental impact of the road transport sector, together with urban freight transport growth, has a notable repercussions in global warming, health and economy. The need to reduce emissions caused by fossil fuel dependence and to foster the use of renewable energy sources has driven the development of zero-emissions powertrains. These clean transportation technologies are not only necessary to move people but to transport the increasing demand for goods and services that is currently taking place in the larger cities. Full electric battery-powered vans seem to be the best-placed solution to the problem. However, despite the progress in driving range and recharge options, those and other market barriers remain unsolved and the current market share of battery electric vehicles (BEVs) is not significant. Based on the development of hydrogen fuel cell stacks, this work explains an emerging powertrain architecture concept for N1 class type vans, that combines a battery-electric configuration with a fuel cell stack powered by hydrogen that works as a range extender (FC-EREV). A literature review is conducted, with the aim to shed light on the possibilities of this hybrid light-duty commercial van for metropolitan delivery tasks, providing insights into the key factors and issues for sizing the powertrain components and fuel management strategies to meet metropolitan freight fleet needs.

Transport consumes about 20% of the world's primary energy, mainly oil. This situation is unacceptable for countries that do not have their own oil reserves and want a stable economy and energy independence. Communities in many countries recognize that these problems continue to accompany the use of road transport and have long paid serious attention to the use of alternative fuels for vehicles, including biofuels, natural gas and hydrogen. However, in the current increase in the number of food industry facilities, it is necessary to deal with food products that have a negative impact on the environment (food fats). According to some data, the amount of garbage per day can range from a few kilograms to tens of tons. Approximately 90% of diesel biofuels (DBs) are mainly derived from processed oils and raw materials, including fats and oils of animal or vegetable origin that are recyclable. Biofuel is a biologically harmless product. In contact with water, the wine does not harm aquatic flora and fauna. In water or soil, it undergoes almost complete biological decomposition. Combustion of diesel biofuels emits much less carbon dioxide (CO2) than combustion of conventional fuels. Of course, there are drawbacks. First, biofuels have low frost resistance. Undiluted biofuel damages rubber hoses and gaskets. Biofuels have a certain shelf life. Due to increased maintenance costs, deposits can contaminate fuel equipment and filters during operation. Particular attention should be paid to the free glycerin that remains during production. The article considers biofuel production technologies and methods of glycerin removal. The focus is on devices that allow you to remove glycerin mobile. As a result, a faucet was proposed in which a filter was installed to remove residual glycerin and a study of its operation using the FlowVision program was performed. The simulation model of operation of the mixer with reception of indicators of its work is executed.
