Hybrid Ship Technology

Explaining the environmental importance of Nobu’s Hybrid Ships.

Solving climate change is a huge international challenge.

Global warming is caused mainly byhuman activities, such as increasing concentrations of carbon dioxide (CO2). Human-made carbon dioxide continues to increase above levels not seen in hundreds of thousands of years.

Scientists claim that 3.5 to 4 percent of all climate change emissions are caused by shipping. In the matter of fact, confidential data from maritime industry insiders show that just 15 of the world’s biggest ships may now emit as much pollution as all the world’s 760m cars.

In addition, ballast water discharged by ships typically contains a variety of biological materials that can cause extensive ecological and economic damage to aquatic ecosystems along with serious human health problems. the negative impact on the marine environment has been identified as one of the greatest threats to the world’s oceans.

The ‘Hybrid Ship’ technology, invented by the owner of TMT international shipping company Nobu Su, was especially developed to reduce CO2 emissions and mitigate the problem of ballast water contamination. Nobu came up with the idea of using hybrid technology to reduce a ship’s requirement for ballast water between 10-20% (depending on the ship’s size), thus minimizing harm to marine life. Meanwhile, the use of a conventionally driven main propeller and an electrically driven duct propeller reduce CO2 emissions because less energy is needed to achieve the required speed.

Nobu Su: “For the shipping industry, a green shift would involve increasing energy efficiency, reducing speeds and shifting to renewable energy and new alternatives to gasoline and other traditional fuels. Hybrid Ship is a step in the right direction – a simple yet efficient Ballast Water Management solution offering greater energy efficiency while protecting the marine environment.”
