Regular Hydrogen Electric Bus Lines Will Open In 2019

Koningshooikt – Van Hool, the independent Belgian bus, coach and industrial vehicle manufacturer has won a contract in Pau, France, to supply 8 Exqui.Cities, known as “tram-buses“, powered by hydrogen. The use of hydrogen buses is not only a first for France it is also a world first for a full BRT (Bus Rapid Transit) system with 18-metre-long articulated tram-buses. This is the first time that hydrogen technology has been integrated as a power source in a tram-bus.

The brand new vehicle is an 18.62 metre-long articulated tram-bus with a 125 passenger capacity and an autonomy of around 300 km. The order of 8 Exqui.Cities will be delivered to the SMTU-PPP (Syndicat Mixte de Transports urbains – Pau Portes des Pyrénées) and the STAP (Société de Transport de l’Agglomération Paloise) in the second half of 2019.

The bus’s power source is an electric hybrid. On the one hand hydrogen (H2) and oxygen (O2) are converted to electricity in the fuel cell using electrolysis in “real time” and, on the other hand, the lithium batteries and electric motors provide additional power wherever and whenever it is needed. The energy that is released when the vehicle’s brakes are applied is also re-used. The use of this technology results in the 0-emission of greenhouse gases or air polluting substances. The vehicle’s only emission is water vapour.

Additional advantages offered by hydrogen buses include their autonomy of over three hundred kilometres and fast re-fuelling (10 minutes). These buses therefore allow bus companies to reach the highest level of operational flexibility and productivity.

Hydrogen-based Electric Bus

FAST, a student team from Eindhoven University of Technology (TU/e) in Netherlands, has designed the world’s first system that allows a bus to drive on formic acid. Their self-built system comprises an electric bus that is hooked up to a small trailer – which the students have christened ‘REX’ – in which formic acid is converted into electricity. The benefits of using formic acid are that it is sustainable, CO2-neutral, safe and liquid.

 

Hydrozine is the energy carrier’s official name. It’s 99% formic acid with a performance enhancing agent. What is striking is that Team FAST, consisting of 35 students, developed this so far unknown fuel all by itself. At the beginning of 2016 they presented an initial scale model that illustrated how it works. After another twenty months of hard work, they now have a system that is 42,000 times stronger and is capable of 25kW power.

In the trailer that was built by the team hydrozine is split into hydrogen and CO2. The hydrogen is then used to produce electricity that powers a city bus of the Eindhoven company VDL. The team calls the trailer a ‘range extender’, REX for short, because the trailer expands the existing range of the bus as a standalone component. The team is still running final tests with the aim of the bus actually operating by the end of this year.

The benefits of hydrozine are many. It is a cheap and safe alternative to the transport of hydrogen that normally requires large tanks and high pressure. The CO2 produced in splitting the hydrozine is also used in the production process, which results in zero net CO2. Hydrozine has four times as much energy density as a battery and since it is a liquid, very few modifications will be required to the current infrastructure of filling stations.

First Driverless Electric Bus Line Opened In Paris

Shuttling their way to a greener city. Paris opening its first driverless buses to the public on Monday. Fully electric and fully autonomous, the ‘EZ 10‘ transports up to 10 passengers across the Seine between two main stations. The buses use laser sensors to analyse their surroundings on the road and for now they don’t have to share it with any other vehicles.

“Fewer people come on board, its slower, its electric, it doesn’t pollute and it can be stored away more easily but it will never replace a traditional bus“, says Jose Gomes, who has been driving buses here for 26 years. He’ll oversee the smooth operation of the autonomous bus.

The shuttles come as Paris faces high pollution levels. City mayor Anna Hidalgo wants to reduce the number of cars, while authorities crack down on traffic restrictions. It may be a short 130m stretch for the buses but for Paris, it’s a big step towards promoting cleaner transport.

Electric Bus Service Without Driver Open Next Week

A self shuttle service, electric and driverless but with passengers, was launched Friday in Lyon (France)  to be tested for a year in the new district of Confluence, “a world first” according to officials of the operation. Two “Armashuttles of the French company Navya, a prototype was tested in 2013 on the hill of the Croix-Rousse, must serve a 10-minute rotations five stops on route commissioning between the Hotel de Region and the tip of the peninsula of the city, Saône side.

Long of 1.3 kilometers and baptized Navly, the service will be open this weekend from 10:00 then at 17:00 from Monday to Friday, 7:30 a.m. to 7:00 p.m., from September 5. Fifteen people in total can be carried in each vehicle. Developed by Keolis, the network operator of the Lyon public transport (TCL) and Navya, a specialist in innovative mobility solutions, the project “meets the challenges of serving the last kilometer,” said Pascal Jacquesson, CEO of Keolis Lyon. Supported by the Metropolis of Lyon and approved in July by the Ministry of Ecology, the “fine service” must supplement the local tram and bus provides TCL, attention including “employees of large companies and administrative and cultural institutions of the district,” he said.

This period of one year is intended to test everything from technology to economic model” to be determined, for its part, Christophe Sapet, Chairman of Navya headquartered in Villeurbanne. Limited at a speed of 20 km / h for the service, the Arma shuttle is a jewel of technology to 200,000 euros each, equipped with guiding cameras in stereovision, laser sensors, GPS and a battery life of six to eight hours.

Already tested in many other cities of the Hexagon, but without passengers, Navya shuttles also run abroad as in Sion, Switzerland. other electric minibus without drivers have already been tested for several months in La Rochelle (Charente-Maritime), as part of European experience.

Electric Cars: The Revolution Comes From Korea

The commercial deployment of electric vehicles has lagged behind due to technological issues in associated with the battery including: price, weight, volume, driving distance, and limited investment in charging infrastructure. Shaped magnetic field in resonance (SMFIR) technology enables electric vehicles to overcome these limitations by transferring electricity wirelessly from the road surface while vehicle is in motion. A research presented by I. S. Suh, from the School for Green Transportation, KAIST – Korea – describes the innovative SMFIR technology used in the KAIST online electric vehicle (OLEV) project as well as its impact on the future of urban transportation. The system integration of the power supply into the OLEV and the vehicle system architecture is also discussed.

The network consists of 24 kilometers (15 miles) of road in the city of Gumi, South Korea. For now, the only vehicles that can use the network are two Online Electric Vehicles (OLEV) — public transport buses that run between the train station and In-dong. the power is delivered by cables that are around 12 inches (30cm) below the road surface. The power is transmitted wirelessly via Shaped Magnetic Field in Resonance (SMFIR), a technology developed by the Korea Advanced Institute of Science and Technology (KAIST) that essentially runs 100 kilowatts of power through some cables at a very specific frequency (20 kHz in this case), creating a 20 kHz electromagnetic field. The underside of the bus is equipped with a pick-up coil that’s tuned to pick up that frequency, and thus AC electricity is produced via magnetic resonance.
