Sunflower Kurenai: travel on an LNG powered ferry

Talk of zero emission travel and decarbonising can get abstract and distant from our daily lives.
Example: shipping is a major source of pollution due to its reliance on marine grade diesel. Using Liquified Natural Gas is seen as one solution to reducing emissions. But what does that mean in practice? If you take a ferry that’s LNG powered, how is it going to be different?
“Solo Travel Japan” took a trip from Osaka to Beppu on Japan’s first LNG powered ferry. It’s 27 minutes without narration, touring the ship’s passenger facilities and sampling food and services.
If you don’t have time to do that, the answer to the question is LNG powered shipping won’t be different, other than a little less background noise.
