Mitsui OSK Lines (MOL) and e5 Lab, which are working to develop and promote electrically powered zero emission vessels, have concluded a Memorandum Of Understanding (MoU) to conduct a joint study of a hybrid pure car carrier (PCC) equipped with a hydrogen fuel cell system and large-capacity batteries.

The companies aim to develop a hydrogen hybrid PCC, which does not emit CO2, SOx, NOx or PM while underway in coastal waters or in ports, that is to say achieving zero emissions, since its propulsion energy would be supplied from electricity from the hydrogen fuel cell system and large-capacity batteries. When navigating in the open sea, the ship’s elecroc propulsion motor would be powered by an LNG-fuelled generator and the large-capacity batteries, resulting in significantly lower emissions than current vessels equipped with diesel engines running on HFO.

MOL has worked towards the realisation of zero emissions from vessels while in ports since it announced its future vision for the next-generation series ISHIN-I car carrier in 2009. In 2012, it launched the world’s first hybrid car carrier, the Emerald Ace (pictured), which is equipped with a large-scale solar power generation system and batteries. The hydrogen hybrid PCC concept marks a further step forward from these past projects, and the company is pursuing the possibility of introducing more extensive and more advanced technologies with the goal of zero emissions.

Both companies will first conduct technological and business feasibility studies of the hydrogen hybrid PCC, and when they gain positive results, they will move on to the next phase of joint development for a practical demonstration of the hydrogen hybrid PCC concept. 

MOL and e5 Lab say they continually engage in measures to reduce merchant vessels’ environmental impact by taking full advantage of both companies’ wide-ranging technological knowledge to ensure the sustainable growth of the shipping industry.
