K LINE procures long-term supply of bio-LNG for car carriers

Kawasaki Kisen Kaisha (K LINE) on Wednesday (1 April) announced that it has signed an agreement to facilitate the long-term procurement of carbon-neutral bio-LNG fuel, also known as liquefied bio methane or LBM, and it has started to use this fuel for LNG-fuelled car carriers. 

The company did not disclose the identity of the supplier. 

It is expected that this procurement agreement will enable K LINE to reduce its greenhouse gas (GHG) emissions by around 60,800 tonnes per year.

Bio-LNG fuel is an alternative to liquefied natural gas (LNG) that is produced from livestock excrement, food residue and other organic waste. 

“It has been confirmed that the GHG emissions from the entire product lifecycle, from the manufacturing to the consumption of the fuel, are lower than the emissions from traditional fuels, and it can be used as-is in existing LNG-fuelled vessels, making it very useful,” it said. 

“Taking advantage of this characteristic, K LINE expects to use it in its existing LNG-fuelled car carriers.”

The bio-LNG that K LINE is now using is ISCC-EU certified, ensuring a degree of sustainability that is in compliance with the European Union’s Renewable Energy Directive (RED). By proactively adopting internationally certified fuels like this, “K” LINE will help decarbonize entire supply chains in collaboration with cargo owners and other stakeholders.

In the K LINE Environmental Vision 2050 – Blue Seas for the Future – , K LINE set the target of achieving net-zero GHG emissions in 2050. In line with this, K LINE has been working to introduce and operate LNG-fuelled ships. 

“The continuous use of bio-LNG is one of its key initiatives to achieve this target. K LINE will continue to work hard on the decarbonization of the marine transport industry, including through the use of carbon-neutral fuels and zero-emissions fuels,” the company added.
