HEMS Global is developing a fuel enhancement system that promises to be more efficient than a diesel engine with simple hydrogen injection. For vehicles the new system eliminates the need to carry cylinders of compressed hydrogen onboard.
The HEMS R&D team are developing a system for generating hydrogen that removes the need for onboard storage.
In the current HEMS system, hydrogen is stored as compressed gas. Long distance operation by the heavier road freight vehicles, railway engines and marine vessels requires substantial onboard storage capacity which is often limited by the available space. In addition, the current level of infrastructure severely limits the applicability of stored hydrogen on vehicles in Australia. The new system generates hydrogen by using energy from the engine exhaust that would otherwise be wasted, thereby improving the overall fuel efficiency and leading to a reduction in emissions.
