Sydney: A prototype, developed by researchers, could successfully show the way to developing hydrogen-powered trucks and ensure clean, green and silent transportation.
The prototype -- an exact replica of an actual lorry -- is operated by remote control and simulates the performance of a long-haul diesel truck.
The hydrogen-powered electrical system could also supply power for truck air-conditioning and radio, along with a trailer refrigeration unit.
Aleksandar Subic, professor and head of the School of Aerospace, Mechanical and Manufacturing Engineering at the Royal Melbourne Institute of Technology (RMIT) University, said given rising diesel costs, new sustainable technologies are also cost effective for industry, according to a university statement.
John Andrews, associate professor at RMIT, said students were testing the small-scale truck against pre-defined dynamic loads, with the result being scaled up using mathematical models to predict the performance of a full-scale truck.
"A wireless data system is being used to monitor truck performance and collect the critical data such as hydrogen consumption rate and electrical power supply," Andrews said.
Subic said: "For residents worried about fumes and noise, the prospect of a silent, zero-emission truck is exciting."
