ULEMCo completes first hydrogen HVO dual-fuel conversion

ULEMCo has completed its first hydrogen dual-fuel conversion in which hydrotreated vegetable oil (HVO) is used in vehicles rather than diesel.

The waste collection truck for Keenan Recycling gives the opportunity to show environmental sustainability by combining the use of hydrogen to reduce tailpipe emissions with the ‘drop in’ renewable fuel.

The conversion shows that hydrogen dual-fuel can work equally well with diesel or the non-fossil fuel HVO, giving the opportunity to address both direct tailpipe carbon dioxide (CO2) emission reduction from the hydrogen (typically 30%), along with the use of a sustainable fuel that can avoid up to 90% of net CO2 emissions.

HVO, produced from waste material such as recycled vegetable oil, can be sustainable if it is produced from a waste-derived feedstock that does not contribute to deforestation. Combining this with the zero carbon fuel hydrogen opens up the opportunity for negative carbon solutions.
