Buses emit a lot of pollutants, and so do police buses. For those that are idling in the middle of a huge crowd, the problem becomes even worse. There is a solution to it. On October 31st, Hyundai Motor signed a memorandum of understanding (MoU) with government agencies – Ministry of Industry, Ministry of Environment, and the National Police Agency, to cooperate on the promotion of FCEV buses for the Korean police.
Police buses spend more time in the middle of a street, usually being used as a rest area for police officers. When there is a massive rally or a huge event, police should be near for safety. So it has been inevitable for their buses to emit a substantial amount of pollutants.
The National Police Agency has cooperated with Hyundai Motor to introduce a hydrogen-powered police bus Elec City since last October. This time Hyundai Motor unveiled a successor to the Hyundai Universe with large cargo space for police equipment.
The high-floor bus provides a better ride and better passenger space at the cost of customer accessibility. It can accommodate 29 passengers including a driver, while only 21 police officers can hop on a low-floor bus. The bus rides fairly high to the ground, and the raised section serves as both to provide a faster ride and accommodate the engine and drive train within. High-floor buses not only suit domestic road conditions but also serve better for the police.
Although the two buses might look alike, they have significantly different structures. For the high-floor buses, baggage holds under the main floor, which means that they lack space for the main compartments of an FCEV. So this Hyundai high-floor bus has hydrogen tanks on its roof to provide enough room for passengers and cargo.
It has two 95-kilowatt fuel-cell stacks, which are also used in the Hyundai Nexo fcev. It has a maximum 240-kilowatt electric motor output, and a 49-kWh battery in the front. On its roof is a hydrogen tank that can store up to 1,014 L of hydrogen. This is the model with both spacious cargo and cabin space.
Being eco-friendly is the biggest advantage of the FCEV police buses. FCEVs do not emit pollutants at all, and they are designed to purify the dirty emissions of other vehicles as they drive. In particular, police buses may have a greater air purification effect due to the high waiting time on the side of city streets. According to the EPA report, the amount of road dust particles on streets was twice that of particles in other city areas. The FCEV police buses will indeed become handy air purifiers.
When the Nexo is driven for just one hour, 26.9 kilograms of air is purified – this is the same amount that 42.6 adults breathe in an hour. The police bus that uses the two of Nexo’s fuel cell battery is even more effective. When this police bus is driven for one kilometer, 4,863 kilograms of air is purified. If run for 86,000km for a year, it would purify 418,218 kilograms of air, which is the same amount that 76 adults can breathe in a year.
The government will buy 802 of the buses for the police force by 2028, and for this reason, the three different government agencies signed a memorandum of understanding (MoU) with Hyundai Motor. The carmaker said it plans to provide two hydrogen-powered police buses to the National Police Agency this year. A test-run of the buses will be concluded by the end of next year, after which production will begin. The hydrogen-powered buses are set to hit the roads in 2021.
Hyundai Motor is developing its eco-friendly FCEVs since the Hyundai NEXO. The company plans to sell 1,600 hydrogen powered trucks in Switzerland by 2025, and also Hyundai Motor and Cummins sign a memorandum of understanding to jointly evaluate opportunities to develop and commercialize electric and fuel-cell powertrains. Initial development will focus on the North American commercial-vehicle market, including working with North American OEMs on the integration of these systems into their vehicles. The police bus will protect the city from crime and pollution at the same time.
