Crystal Adopts SulNOxEco™ in Fast-Growing Cruise Market

Crystal Adopts SulNOxEco™ in Fast-Growing Cruise  Market

SulNOx, the greentech innovation company helping the shipping industry reduce emissions, lower fuel costs 
and meet sustainability targets, has made its first public foray into the rapidly expanding cruise market.
The new entry for the UK-listed group follows a successful evaluation by Crystal Cruises of its core 
decarbonisation product, SulNOxEco™ Fuel Conditioner.

The Crystal Symphony, a Nassau-registered 51,068 gross tonnage vessel powered by six Wartsila-Sulzer diesel engines, took three deliveries of SulNOxEco™ Conditioner while berthed in Greece in April 2024, Germany in August and Italy in November. An evaluation between May and December 2024 showed an average fuel saving of 3.4% across the full period.

Data collected also noted a significant reduction in black smoke from Symphony’s stacks. This result is 
particularly important for cruise line operators, both when located in ports and in gaining access to fjords for 
the sizeable Norwegian cruise market. By reducing particulate matter, SulNOx helps ensure cleaner engine 
performance and enhances the onboard experience for guests.

Emissions monitoring with Crystal reflects compelling results witnessed by other major shipping groups 
evaluating SulNOxEco™. SulNOx has made very significant progress in signing major clients operating bulkers,

tankers, containers and cruise ships in Asia and Europe.
Crystal is now adopting the use of SulNOxEco™ across its fleet. It follows Eastern Pacific Shipping, one of the  world’s largest privately owned shipping groups, which in recent weeks announced adoption in an initial 30 vessels in its 300-strong fleet. In addition, it made a significant investment in SulNOx through EPS Ventures. 

The EPS partnership with SulNOx came within weeks of an investment by US-based shipbroker and consulting group McQuilling Partners Inc. They joined the growing list of international marine industry heavy hitters and former senior commodity traders backing SulNOx after an eight-fold share price hike in 18 months.
Working with Crystal is a key milestone for SulNOx as it accelerates its reach into the shipping industry.

Commenting on the Crystal Cruises trial, SulNOx CEO Ben Richardson said:

“We are excited to be working with a well-known brand in the fast-growing cruise ship market. The flip side of 
this increasingly popular leisure activity is the existing and potential level of environmental pollution from some extremely large vessels.

SulNOx is pleased to be part of the solution for the industry, helping to reduce emissions significantly, while delivering fuel cost savings and supporting ship operators to meet ESG and CII goals.” 

Roberto Fazi, Senior Vice President of Marine Operations, Crystal added:

“The results of the tests carried out after the introduction of SulNOxEco onboard have proven to be very 
promising. We observed measurable fuel savings, cleaner engines, and reduced emissions. As sustainability 
becomes a key driver for growth in the cruise sector, this innovation helps us enhance operational efficiency, 
reduce our environmental impact, and provide a more sustainable experience for our guests.”

Angus Macdonald, Director of SulNOx master distributor A&S International, commented:

“It has been a pleasure working closely with the Crystal team and the Crystal Symphony crew, demonstrating 
the emission reduction and fuel saving capabilities of SulNOxEco over the extensive evaluation. The real-world benefits are plain to see, and we’re excited to continue supporting the maritime industry’s journey toward a greener future.” 

SulNOx’s organic, biodegradable products offer a zero-capex, immediate transition solution for all major 
industries under pressure to cut emissions, meet regulatory targets and reduce fuel consumption.
