SAFRA presents its hydrogen bus range at HyVolution in Paris

The bus manufacturer SAFRA presented at the HyVolution fair held in Paris on 4 and 5 April, its latest developments in the Businova range. This urban bus is now available in a zero-emission version, in pure electric slow or fast charging, but also in an electric hydrogen version. It is this latest technology that was presented at the HyVolution fair on the common stand of the Occitanie Region. During a press briefing, the company announced that it had just won a market of several hydrogen units for a French agglomeration, making it the first French manufacturer of hydrogen buses. This vehicle, again very innovative, will be equipped with a fuel cell manufactured by Michelin.
From its genesis, the Businova was designed to adapt to technological developments, its architecture allowing the vehicle to evolve to different modes of motorization. This is what has strongly mobilized the teams of the Businova program in recent months, to develop a complete range with different sizes (9.5m, 10.5m and 12m) and several engines. Indeed, thanks to its architecture composed of a passenger chassis and its energy pack, as well as the configuration of the side boxes, the Businova has the ability to integrate different types of engine, from pure electric to H2 fuel cell, without major technical constraints.
The Businova is thus marketed in very low emission mode with its «plug-in hybrid electric» range offered with a Diesel extender (Euro VI) or NGV, which perfectly meets the requirements of Group 1 of the Energy Transition Law Decree for Green Growth. It is also available in zero emission version, in 100% electric with a slow charging system in the evening at the depot, or fast by reverse pantograph, but also in hydrogen version. It is on these aspects of operational agility and vehicle scalability that the Businova keeps a real step ahead of its competitors.

From the beginning of the Businova project, the SAFRA company was very interested in hydrogen technology, which allows to maintain a reduced battery capacity by providing additional energy. The Businova H2 is the result of the original architecture developed by SAFRA since 2011 and certified. Retaining all the vehicle’s architecture (passenger compartment, chassis, deck, mechanical components, batteries, electrical architecture) SAFRA has adapted a hydrogen system on the initial 250 kW electric traction line, powered by a lithium-battery pack.132 kWh ion. The fuel cell is supplied by Michelin, and the system incorporates a storage of 28 kg of hydrogen at 350 bars, which allows to cover a range of more than 300 kms per day. The Michelin hydrogen module is built around a 30 kW fuel cell. Michelin battery technology can cover a range of applications from 5 to 100 kW. Important integration work was carried out to obtain a reduced weight and a very compact volume, in order to facilitate the integration into the vehicle.

The new range offered today by SAFRA perfectly meets the needs of the French market in zero-emission vehicles following the latest directives of the energy transition law, but also at the international level, with European projects related to carbon-free mobility solutions.
