They're selling quite a few scrubbers too.

The adoption of scrubbers is a boon for companies that make them. In 2017, Wärtsilä, a leading scrubber manufacturer, was building devices for 400 cargo and cruise ships. By the end of 2018, that had ballooned to 2,400 contracts.
For now, sulfur-free, zero emission cruising is out of reach. Experts say battery, solar, wind, hydro, and biofuel technologies are simply not powerful enough yet to propel an 18-story, 54,000-ton ship through the ocean, not to mention providing air conditioning, laundry service, and all-you-can-eat buffets to thousands of passengers and crew aboard.
“Even if we covered our entire decks with solar panels the best we could do is power a couple of elevators,” said Carnival Corporation’s Senior Vice President of Marine Technology and Refit Mike Kaczmarek.
