The Mercedes-Benz Citaro FuelCELL-Hybrid , also known as Mercedes-Benz O 530 BZH or Citaro BZH , is a fuel cell hybrid-powered bus manufactured by the German commercial vehicle manufacturer Mercedes-Benz based on the successful Citaro bus model and the successor to the Mercedes-Benz Citaro BZ . In the course of various research and funding projects , the O 530 BZH is used to test the everyday suitability of the fuel cell drive in local public transport . The vehicle is the successor to the Citaro BZ .
The prototype was presented on November 16, 2009 in Hamburg .
On August 18, 2011, the first vehicles were put into operation at Hochbahn AG .
At Daimler, the fuel cell hybrid bus was expected to be ready for series production in 2015. Until then, further experience should be gained with the 31 planned pre-series units. As of November 2019, however, a series tour is only expected in 2022.
Technology and equipment
The O 530 BZH differs from the previous series in that it has a serial hybrid drive . It is driven by two electric wheel hub motors on the rear axle , each with an output of 80 kW.
The core element is the fuel cell , which consists of two modules with 396 individual cells each and a total output of 120 kW, i.e. 60 kW per unit. The cooling is done by four large fans on the vehicle roof, which keep the fuel cell directly next to it at an operating temperature of around 80 degrees Celsius. The hydrogen supply, which is up to 35 kilograms in size , is stored in seven 350 bar compressed gas tanks on the front half of the roof . The fuel consumption is 10 to 14 kilograms of hydrogen per 100 kilometers.
For the purpose of recuperation , the vehicles are also equipped with a 330 kilogram lithium-ion battery , which is designed for a capacity of 26 kilowatt hours of electrical energy. This corresponds to a purely electric driving distance of three to five kilometers.
The vehicles share the hybrid technology with the Citaro G BlueTec Hybrid, also from Mercedes-Benz , a regular-service bus with a diesel hybrid drive.
The total weight is 13.2 tons, which saves around one ton compared to its predecessor. The range is around 250 kilometers. The Citaro BZH is approved for the transport of 76 passengers, five more than before. All pre-series cars are designed as three-door, with inward-swinging double doors being used.
In contrast to the demonstration vehicles and the cars for Brugg, Milan and Karlsruhe, the fuel cell hybrid Citaros in Hamburg, Bolzano and Stuttgart have a so-called advertising front, which can also be selected as an equipment option for the series Citaro. The area between the windshield and the bumper is designed without contours (Stuttgart), or without contours and Mercedes star (Hamburg and Bozen), to make it easier to apply stickers .
Locations
A total of 23 Citaro FuelCELL-Hybrids are currently in use at various companies in Europe, the majority of which forms an integral part of the European project Clean Hydrogen In European Cities (CHIC), which is the successor to the EU in research into hydrogen drive in local public transport . CUTE and HyFLEET funding programs : CUTE starts:
Hamburg
The first of a total of four vehicles were handed over to Hochbahn AG in Hamburg on August 18, 2011 as part of the CHIC project and assigned to the Hummelsbüttel depot there - classified under the company numbers 1141 to 1144 . The hydrogen filling station already used for the previous CUTE projects is also located there .
The cars marketed under the name of SauberBus have a leaf-look sticker that deviates from the usual red and white elevated railway color scheme and initially came to the north of Hamburg - mainly on lines 24 ( U Niendorf Markt - Rahlstedt station ), 174 ( US Ohlsdorf - U Volksdorf ), 176 ( U Ohlstedt - S Poppenbüttel ), 276 ( U Ohlstedt - Sasel Mellingburgredder) and 192 ( Langenhorn Markt - Norderstedt Glashütte) - are used. Line 35 ( Hamburg Messe - Rahlstedt Sorenkoppel) has also been included in operations since the hydrogen filling station in HafenCity went into operation.
From December 2013, the hydrogen buses will mainly be used on the newly introduced line 111 ( Altona station - HafenCity Shanghaiallee), which serves a large part of Hamburg's sights along the northern bank of the Elbe .
Since December 2014 the bus route 109 (Hauptbahnhof - U Alsterdorf) has been presented as an innovation line . Here the elevated railway is using various new drive concepts on a test basis. The fuel cell buses have also served this route since then.
The leaf design has now been removed from all vehicles and replaced by the conventional elevated train color scheme in red and white. Several large advertising stickers and the lettering fuel cell bus now indicate the special features of the four Citaros.
The project was ended at the beginning of 2019, on the one hand because Mercedes was unable to deliver the bus in series and because the storage of hydrogen in residential areas raises safety concerns.
Hamburger Hochbahn announces on its website that it intends to put two articulated buses from Mercedes-Benz with fuel cell drives into operation from 2021.
Brugg
As of the end of 2011, five more Citaro FuelCELL-Hybrids went to Postauto Schweiz AG as part of CHIC , where they were handed over to the Postbus operator Voegtlin-Meyer AG from the canton of Aargau with the numbers 274 to 278 . A hydrogen filling station and a parking garage specially designed for the vehicles were put into operation on the company premises. The five cars were used freely in overland traffic around Brugg . By the summer of 2015, the five buses had covered a total of one million kilometers. 80 tons of hydrogen were used, 70 tons of which were produced in Brugg. All the hydrogen used came from renewable energy sources (hydropower, solar, wind energy or biomass systems).
The pilot project at PostBus was discontinued at the beginning of 2017 after around five years.
Milan
On March 14, 2012, three vehicles were presented for the CHIC project city of Milan . The vehicles were lined up at the Azienda Trasporti Milanesi (ATM) with the numbers 2000 to 2002 and stationed in the San Donato depot , where the systems necessary for hydrogen operation are also located.
For passenger traffic, the vehicles will initially be used in the southeast of Milan in the immediate vicinity of the depot on bus route 84, which runs from San Donato via Rogoredo and Corvetto to Largo Augusto in the city center. The bus line initially follows the M3 metro line to Corvetto underground station and then continues via Viale Puglie, Piazza Insubria, Via Spartaco and past the Palazzo di Giustizia to the city center.
Karlsruhe
Since June 11, 2013, the Karlsruhe Institute of Technology has been using two Citaro FuelCELL-Hybrids on its own works transport (KIT-Shuttle). The changeover to vehicles with fuel cell hybrid drives happened in the course of the commissioning of a hydrogen filling station on the premises of the KIT.
Bolzano
On August 6, 2013, Südtiroler Transportstruktur AG (STA) received the first of five fuel cell Citaros, the four other cars followed in September. This will Bolzano used as the fourth city in the CHIC project the Citaro BZH. The entire fleet is operated by SASA Bozen and is included in its fleet under the numbers 428 to 432. The use of the fuel cell vehicles is initially planned on the ring lines 10A and 10B (hospital ↔ cemetery ↔ train station ↔ hospital).
In the next few years these buses will also be used on lines 3 (Kaiserau-Bahnhof), line 5 (Perathonerstraße) and, very rarely, as replacement buses on line 201 (Merano ↔ Bozen).
Stuttgart
At the end of 2013, Stuttgarter Straßenbahn AG joined the Clean Energy Partnership (CEP) research project . As a result , three Citaro FuelCELL Hybrids will initially be tested in regular service in Stuttgart from 2014 under the name S-Presso (Stuttgart practical testing of hydrogen-powered buses). The test phase of the project, which is estimated to have a total funding volume of 3.2 million euros, is initially set to run for three years and is part of the Federal Hydrogen and Fuel Cell Technology (NIP) innovation program , which is coordinated by the National Organization for Hydrogen and Fuel Cell Technology (NOW). The three cars were added to the SSB fleet with numbers 5501 to 5503 and use the public hydrogen filling station on Flughafenstrasse to refuel. There is no in-house filling station.
The deployment, which begins on March 3, 2014, will initially be limited to line 79 ( Flughafen / Messe - Plieningen Garbe), which runs near the airport , so that the cars can be deployed in close proximity to the hydrogen filling station there. The hydrogen hybrid test operation was later extended to line 67 ( Fellbach industrial area - train station - Gartenstrasse), for which a fourth Citaro BZH was delivered by mid-2014.
During the CUTE, three fuel cell Citaros from the predecessor series O 530 BZ were used in the state capital of Baden-Württemberg . This makes Stuttgart the second city after Hamburg in which both the fuel cell and fuel cell hybrid Citaro are being tested.
Frankfurt am Main
Since the end of 2017, two of the fuel cell vehicles previously used in Brugg have been in use in the Rhine-Main area at the Winzenhöhler company from Groß -zimmer for the internal bus transport of the Höchst industrial park . For the trial run jointly organized with the operating company Infraserv , hydrogen is used, which in the industrial park is an intermediate product from the chem. Industry emerges. The buses are refueled at a public Agip hydrogen filling station on site, which was opened in 2006 as part of the “Zero Regio” project.
The use of the hydrogen hybrid Citaros in Höchst is part of the National Innovation Program for Hydrogen and Fuel Cell Technology of the Federal Ministry of Transport.
Since the beginning of 2020, one of the vehicles previously used in Frankfurt am Main has been in use at ESWE Verkehrsgesellschaft in Wiesbaden under the car number 96 and with a new paint job. It is the only solo vehicle in the state capital that has 3 double doors. On the other side of the Rhine, the Mainzer Verkehrsgesellschaft has opted for a former model from Hochbahn AG . Both vehicles are refueled at the hydrogen filling station at the ESWE Verkehrsgesellschaft depot . The two companies are each responsible for maintenance.
