  • O ônibus movido a hidrogênio (português brasileiro) ou autocarro movido a hidrogénio (português europeu) são ônibus que utilizam células combustíveis de hidrogênio como fonte de energia para seus motores elétricos (ao invés do tradicional diesel), algumas vezes amplificadas com o uso híbrido de baterias ou supercapacitores. Poucas companhias estão conduzindo as pesquisas em células combustíveis de hidrogênio e testes práticos. Elas incluem: * Daimler AG, com trinta e seis unidades experimentais providas de células combustíveis pela Ballard Power Systems, contando com três anos de testes em onze cidades, em janeiro de 2007. * Thor Industries, baseado na tecnologia de células combustíveis UTC Power * Irisbus, baseados na tecnologia UTC Power Nas últimas décadas, a importância de se investir em tecnologias que não degradem o meio ambiente foi crescendo cada vez mais. É de conhecimento público que o uso de transportes que utilizam combustíveis fósseis são um dos principais causadores de poluição do ar atmosférico, devido aos poluentes advindos da queima dos combustíveis. Foi nesse contexto que surgiram as primeiras pesquisas para a criação de veículos movidos a eletricidade, gerada por células combustíveis abastecidas por hidrogênio, ainda na década de 1980. No mundo, cerca de 20% da emissão de CO₂ são causadas pelo sistema de transportes, além da participação deste para o efeito estufa e emissão de outros poluentes. Já no Brasil, segundo o Ministério da Ciência e Tecnologia (MCT), a emissão é cerca de 9% do total. Sendo este um número substancial, tanto a nível mundial, quanto a nacional, a busca de alternativas é o planejamento para o que precisa ser o futuro. O Brasil possui a maior frota de ônibus do mundo. Apenas esse tipo de transporte responde a mais de 60% dos deslocamentos urbanos, enquanto os carros ficam com menos de 30% de participação. Entretanto, o ônibus emite apenas 7% dos gases poluentes, enquanto os carros contribuem com cerca de 50%. Esses dados, em união com os dados da participação dos sistemas de transportes na poluição, justificam as pesquisas nacionais brasileiras na criação de ônibus movidos a hidrogênio. Para fazer o ônibus a hidrogênio funcionar, é necessário produzir o hidrogênio a partir da eletrólise, que normalmente é feita da água. A seguir, é colocado o combustível em uma célula, juntamente com o oxigênio, o comburente, onde ocorrem reações eletroquímicas. Os primeiros testes com esse tipo de ônibus foram feitos na Europa, em 2004. No Brasil, houve dois projetos: o da Empresa Metropolitana de São Paulo (EMTU) e o da Universidade Federal do Rio de Janeiro (UFRJ). (pt)
  • A fuel cell bus is a bus that uses a hydrogen fuel cell as its power source for electrically driven wheels, sometimes augmented in a hybrid fashion with batteries or a supercapacitor. Several companies are conducting hydrogen fuel cell research and practical fuel cell bus trials. These include: * Daimler AG, with thirty-six experimental units powered by Ballard Power Systems fuel cells completing a successful three-year trial, in eleven cities, in January 2007. * Thor Industries (the largest maker of buses in the U.S.), based on UTC Power fuel cell technology * Irisbus, based on UTC Power fuel cell technology There are also fuel cell powered buses currently active or in production, such as a fleet of Thor buses with UTC Power fuel cells in California, operated by SunLine Transit Agency. Hydrogen-powered fuel-cell buses began operating in Beijing on an experimental basis in 2006. Three fuel cell buses, made by Daimler in Germany and purchased with a grant from the U.N. Development Programme, were the first fuel cell buses to enter operation in China. The technology has not gained broader use in the city because air pollution reduced the efficiency and operating life of fuel cells. The first Brazilian hydrogen fuel cell bus prototype began operation in São Paulo during the first semester of 2009. The hydrogen bus was manufactured in Caxias do Sul, and the hydrogen fuel will be produced in São Bernardo do Campo from water through electrolysis. The programme, called "Ônibus Brasileiro a Hidrogênio" (Brazilian Hydrogen Autobus), includes three additional buses. The town of Whistler in British Columbia, Canada owned and operated the largest fuel-cell bus fleet in the world, having been put in operation for the 2010 Winter Olympics. However, the costs were too high and the program halted in 2015. In Aberdeen, Scotland, the Aberdeen Hydrogen Bus Project currently has 10 hydrogen fuel cell buses operating, the largest fleet in Europe. The Fuel Cell Bus Club is a global cooperative effort in trial fuel cell buses. Ford began leasing E-350 shuttle buses in late 2006. It conducted some trials: * 1998 - Chicago and Vancouver, there were two-year three-bus demonstration projects. The six buses in those trials, which used an earlier version of Ballard fuel cell than the Fuel Cell Bus Club's trial and New Flyer Industries 40 foot low floor F40LF bodies, carried more than 200,000 passengers and traveled over 118,000 kilometers (73,000 mi). The 3 Vancouver units were deactivated,some were sold back to Ballard, who made the fuel cells and the others were converted to diesel- electric hybrids and eventually scrapped. * 2004–present Oakland and California a two-year three-bus trial. During this period, AC Transit and Sunline Transit (Palm Springs, California) have been operating three buses and one bus respectively. This trial has shown promising results and has been extended until new buses listed below are delivered. * 2004–2006 Santa Clara Valley Transportation Authority (Santa Clara, California) operated 3 buses Manufactured by Gilig Corp of Hayward California which were equipped with Ballard fuel cells. VTA reported in the press that these buses were too expensive to operate and that they would not continue with their trial. * Japan, operating FCHV-BUS (Fuel Cell Hybrid Vehicle) manufactured by Hino Motors and Toyota Motors under Japan hydrogen fuel cell project. * 2003–2004 – Tokyo, one year and four months one-bus demonstration operated by Toei Bus. * 2005 – Expo 2005 Aichi, six-month eight-fleet trial as inter-site shuttle. During Expo, 8 FCHV-BUSes carried one million visitors and traveled about 130,000 kilometers. * 2006-Tokoname, Aichi, ex-Expo 2005 fleets are leasing 1 to Chita Noriai as route bus in Chūbu Centrair International Airport island, and two to Chubu Sky Support as ramp bus in Centrair. * 2009 – Oakland, California. A 12-bus trial program in this city in the San Francisco Bay Area is underway at AC Transit which features buses specially designed by Van Hool of Belgium. These buses use near ambient pressure, PEM fuel cells manufactured by the Hartford, Connecticut-based United Technologies Corporation (UTC). AC Transit is joined by operating partners Santa Clara Valley Transportation Authority (VTA) of Santa Clara County, SamTrans of San Mateo County, Golden Gate Transit of Marin and Sonoma counties, and San Francisco Municipal Railway (SF Muni) in the City and County of San Francisco which will operate the buses occasionally. UTC is also purchasing four additional buses for use in Hartford, Connecticut under AC Transit's contract with Van Hool. Deliveries are scheduled to begin in the third quarter of 2009 and be completed in 2010. * A fuel cell bus in Perth, Western Australia * Toyota's FCHV-BUS at the Expo 2005 * Mercedes-Benz (Daimler AG) Citaro fuel-cell bus in Aldwych, London (route RV1), on 19 October 2005 * An elevated view of London's first HyFLEET:CUTE hydrogen fuel cell bus, showing the six roof-mounted hydrogen fuel tanks. * Tecnobus Gulliver U520 ESP run by German transport company Rheinbahn * A Van Hool Hydrogen-powered bus in Aberdeen, Scotland (en)
