Australian company to commercialize hybrid hydraulics technology
by Mike Adams, the Health Ranger, NaturalNews Editor
Australian company Permo-Drive Technologies will bring its innovative hybrid hydraulic system to market via a collaboration with automotive supplier Dana Corporation.
So there is little surprise about increasing focus on an automotive innovation called hybrid hydraulics, which integrates hydraulics technology with braking and propulsion systems, and claims to deliver significant fuel savings.
Re-acceleration to get the vehicle moving again results in considerable fuel consumption and vehicle emissions.
The concept of hybrid hydraulics involves capturing the energy normally wasted during braking, and releasing it back into the drive shaft when needed during acceleration.
Australian company Permo-Drive Technologies is one of the first companies in the world to develop a hybrid hydraulic system, and recently announced an agreement to collaborate with US-based automotive supplier Dana Corporation to commercialise the technology.
"Our strategy is to license out the technology for individual fields of application like refuse trucks, buses, and small, medium, and large urban delivery vehicles," Permo-Drive Technologies CEO Willem de Vylder said.
When the accelerator is released, the vehicle's kinetic energy is used to pump hydraulic fluid from a low-pressure reservoir into a high-pressure accumulator (storage cylinder).
For drivers, performance of the vehicle during acceleration is enhanced by the injection of the energy previously stored during braking.
On a wider scale, reduced fuel usage and braking by drivers also subjects the public to lower fuel and noise emissions respectively.
De Vylder says Permo-Drive are working on demonstration projects, and presenting to regulators and commissions in the UK and Europe to increased the profile and credibility of hybrid automotive technology.
But once it warms to the general concept of hybrid technology, the automotive industry will still face a choice between two varieties - hybrid electrics and hybrid hydraulics.
Currently, commercialisation of hybrid hydraulics technology is focused on larger vehicles such as trucks used in waste industry, and military transports.
