In a joint sustainability research project between Nanyang Technological University (NTU) and Beijing's Tsinghua University, as well as transport companies SBS Transit and Higer (Suzhou Jinlong), the Higer KLQ6129GQH2 was conceptualised in 2009. The development of this bus took seven months back in Higer's plant in Suzhou and shipped over to Singapore in June 2010 for testing and preparation for Singapore's Youth Olympic Games (YOG).
The bus was unveiled on 20 July 2010 with much fanfare, is the first hybrid fuel-cell battery bus in Singapore, powered by both Hydrogen and Lithium-Ion batteries. The fuel cell system converts the Hydrogen stored in the bus into electricity, which supplies power to both the bus and charging the battery. Such technology produces zero carbon emission and only emits clean water, eliminating the dependency on fossil fuels.
The only time that the bus was observed to be in operation was during the YOG games, where it ran a shuttle service to ferry athletes and visiting delegates in the Games Village, located within NTU premise. A hydrogen refuelling station for the bus was erected across NTU's School of Biomedical Science on an empty plot of land off Nanyang Drive. This would be where the bus performs its overnight parking. After the YOG concluded, the bus was abandoned there until late 2011 where it was transferred to Car Park S, as the plot of land is designated for construction of NTU's Experimental Medicine Building.
It continued to lay abandoned at the car park until early 2015, where it was finally removed and disposed altogether. What is apparently an ingenious solution to solve the reliance on fossil fuel and providing an environmentally sustainable zero emission public bus to reduce carbon footprint has gone to waste, because of the choice of fuel
