"Quicklime, also known as calcium oxide (CaO), is a white, alkaline substance produced by heating limestone (calcium carbonate) at high temperatures. This process, called calcination, releases carbon dioxide and leaves behind quicklime. It's a versatile chemical compound with numerous applications in construction, agriculture, and various industrial processes."

So they're going to use energy to make the quicklime, and release CO2 in the process, in order to capture CO2 from the ships.

Sounds to me this is only viable as a means of CO2 capture if quicklime is a wasteful byproduct of some other manufacture process.
