GreenLite is powered by two sources of energy hydrogen and lithium-ion batteries. A fuel cell system housed on board the bus acts as an "energy converter" that converts hydrogen into electricity which powers the bus and charges the batteries when necessary.
Unlike other hydrogen fuel cell buses which typically have capacities of between 80kW to 150kW, this unique dual design combining a proton exchange membrane (PEM) fuel cell stack with lithium-ion batteries enables the bus to run on a fuel cell power capacity of only 40kW.
The GreenLite research project is developed in partnership with Singapore's Land Transport Authority (LTA), Singapore bus company SBS Transit as well as Higer Bus Company Limited, one of the fastest developing bus manufacturers in China.
Mr Lew Yii Der, LTA's Group Director of Corporate Planning & Research, said: "LTA is committed to explore innovative clean technologies for sustainable land transport solutions. This fuel cell bus is the first of its kind in Singapore and we will learn much about its feasibility as a public transport option on our roads. We are proud to be a partner of this project. "
SBS Transit Chief Executive Officer, Mr Gan Juay Kiat, said: "SBS Transit runs the bulk of public bus services in Singapore. We are very conscious of the impact of our operations on the environment. That is why we don't just stop at replacing our fleet with new buses that are Euro 5 complaint. We believe that newer, alternative forms of energy are the way to go which is why we are embarking on these trials."
