MOL pursues hydrogen PCCs

Japan-based ship operator Mitsui OSK Lines (MOL) has concluded an MoU with marine technology specialist e5 Lab to conduct a joint study of a hybrid pure car carrier 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 PMs while underway in coastal waters or in ports, in other words, achieving "zero emissions," since its propulsive force would come from electricity supplied by the hydrogen fuel cell system and large-capacity batteries. When navigating in the open sea, the hydrogen hybrid PCC’s 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 that run on oil fuels.

The Emerald Ace

MOL says it has worked to realise zero emissions of 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, which is equipped with the world's largest-scale solar power generation system and batteries. The hydrogen hybrid PCC concept marks a further step ahead 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 of hydrogen hybrid PCC based on the results.
