Carbon capture on vessels while they sail has been achieved behore by Mitsubishi in 2021. https://www.mhi.com/news/211020.html https://www.mhi.com/news/211020.html The challenge is where to store that CO2 while sailing as each ton of fossil fuel burnt creates 3 tons of CO2. The average ocean going vessel burns approx 200 tons of fossil fuel per day = 600 tons of CO2. On a 10 day journey that results in 6000 tons of CO2. That requires a lot of space and additional weight.
