Ocius has developed and implemented its own proprietary hybrid propulsion system on board various SolarSailor commercial passenger vessels.
See this BBC report for an insight into our hybrid marine technology and what makes Ocius special.
Hybrid marine power combines electric drives with the power and range of hydrocarbon/alternative fuels. Like the hybrid car; the system is controlled and optimised by a computer. In the case of a hybrid marine power system, renewable energy available on the water such as solar power can also charge batteries and the vessel can sail.
A “series” hybrid layout uses all-electric drives with generators and solar supplying electricity to the batteries. A “parallel” hybrid is where both the internal combustion engines and the electric motors can drive the propeller. There are advantages and disadvantages of both systems.
HMP refers to the electric-drive motor system, which operates separately from fossil fuel engines in a layout analogous to the hybrid car.

Two designs used by OCIUS – the final design depends on the application.
The HMP Technology offers a number of advantages compared to ordinary marine propulsion:
- Significant fuel savings and return on investment
- The effective combination of several sources of power (solar, wind, wave and fossil fuels)
- Unique zero emissions capability when vessels are in port or alongside the wharf
- Use of renewable energy, such as wind, sun and wave energy, all abundant at sea
- Proven reduction of carbon dioxide, nitrous oxide and particulate emissions
- Very low noise emissions/stealth capability
- Compatibility with advances to come in battery cell technology
- Adaptability to the increasingly tough regulatory environment
- The generation of measurable carbon credits for sale
- Approved by NSW waterways, HK Marine Department
- Developed with Schneider Electric, owned by OCIUS
