Formed within the CCR Study Group in August 2019, the WG aims to explore the feasibility of the concept of utilizing methanation technology for zero-emission ship fuels.
The CCR Study Group was established with the objectives of proposing effective carbon neutral measures to reduce the use of fossil fuels by offering alternative energies such as synthetic methane, and contributing to the establishment of a new energy supply system by 2050.
“Through its activities, the WG aims to reduce greenhouse gas emissions to zero in sea transportation, which accounts for 99.6% of Japanese imports and exports, and thereby contribute to the formation of a sustainable society,” the joint press release said.
Specifically, the nine companies plan to assume carbon recycling supply chain of methanation fuel that involves the supply of feedstock CO 2 , transportation of the feedstock, methanation, and conversion into marine fuel.
As explained by MOL, methanation is a technology for synthesizing methane, the main component in natural gas, by causing a chemical reaction between hydrogen and CO 2 in a reactor vessel filled with a catalyst.
It uses emitted CO 2 separated and captured from industrial facilities. As the CO 2 generated when combusting synthesized methane is considered to be offset by the separated and captured CO 2 , it is expected that CO 2 emissions can be significantly reduced by using hydrogen generated by electrolyzing water with electricity derived from renewable energy.
Under the plan, the stakeholders will calculate the estimated amount of CO 2 emissions in the supply chain, and based on these results, identify technical challenges and develop a roadmap for its realization.
The first stage of activities involves:
In addition to obtaining an approximate value of CO 2 emissions in this assumed supply chain, the group will move forward with identifying challenges and decide whether to proceed with subsequent next-stage activities.
