Ship Carbon Recovery Working Group (WG) of Japan Carbon Capture and Reuse (CCR) Research Group has confirmed that the carbon-recovered methane produced by methanation technology can be recognized as a zero-emission ship fuel.
A technical paper was published in the latest issue of the Journal of Japanese Society of Marine Engineering, describing the calculation process and evaluation details performed by the working group.
Methane is the main component of natural gas. Simply put, methanation is a technology for synthesizing methane by causing a chemical reaction between hydrogen and carbon dioxide in a reactor vessel full of catalysts to produce methane, and carbon dioxide is captured from the exhaust emissions of industrial facilities, which can offset the carbon dioxide produced by burning methane as fuel.
Carbon recovery, the process of capturing and reusing the emitted carbon dioxide, is becoming more and more important as one of the ways to achieve carbon neutrality.
In order to explore the feasibility of the concept of using methanation technology to produce zero-emission marine fuel, the Ship Carbon Recovery Working Group was established within the CCR framework and began research activities in July 2020.
Since the basic premise of the working group's activities is that carbon cycle methane can be considered as a zero-emission fuel, the working group is first committed to assessing its potential.
The working group assumed and evaluated the following four processes as the supply chain of carbon recovery methane fuel-carbon dioxide separation and capture, carbon dioxide transportation, methanated fuel synthesis and methanated fuel liquefaction.
