The world's first hydrogen hybrid sweeper was unveiled at the RWM in the NEC Birmingham last week.
Stock Sweepers have been working in collaboration with Water Fuel Engineering to develop a low emission auxiliary engine which powers the vehicle's brushes and vacuum.
The WFE HydroGen 3.1 electrolyser works synergistically within the conventional diesel engine to introduce oxy-hydrogen gas into the combustion chamber. The richness of the mix reduces fuel consumption by at least 15% and carbon emissions by as much as 80%.
'With modern legislation we need to be sure we don't just leave the streets clean but the air as well and this vehicle can boast the lowest emissions of any sweeper on the market,' said Jeff Stock, managing director of Stock Sweepers.
