2008年,中国超越美国成为世界第一大二氧化碳排放国,中国全年的排放量占了全世界总排放量的五分之一。在节能减排的迫切需求下,2009年以来,国家出台了一系列政策法规,推广新能源汽车的大潮滚滚而来。城市公交作为新能源汽车示范运行的前沿阵地,迎来了混合动力、纯电动、燃料电池、醇燃料、超级电容等类型的新能源客车。通过示范运营,公交企业反映节能减排效果明显,但电池寿命短、难以集中回收,混合动力系统技术仍待完善,配套设施不健全等问题实际存在。在这个时间的节点上,零排放、低噪音,加之技术日臻成熟、弊端正被一一克服的无轨电车的复兴迎来黄金时代。
In 2008, China surpassed the United States to become the world’s largest emitter of carbon dioxide. China’s annual emissions account for one fifth of the world’s total emissions. In the urgent need of energy-saving emission reduction, since 2009, the state has promulgated a series of policies and regulations to promote the tide of new energy vehicles billowed. As the forefront of new energy vehicles demonstration operation, urban bus ushered in the new energy bus of hybrid, pure electric, fuel cell, alcohol fuel, super capacitor and other types. Through demonstration operation, bus enterprises reflect the obvious effect of energy-saving and emission reduction, but the battery life is short, it is difficult to focus on recovery, hybrid power system technology still to be perfected, and other supporting facilities are not perfect. At this time of the node, zero emission, low noise, coupled with the technology matures, the drawbacks are being overcome by the revival of the trolleybus ushered in the golden age.
