Sulnox Group Plc

(the "Company" or "Sulnox")

Australia patent granted

(Aquis Stock Exchange: SNOX)

Sulnox, the greentech company delivering lower fuel costs and emissions with zero capex, is pleased to announce that it has secured a strategically important patent in Australia.

Consistent with Sulnox's more than 100 patents granted to date in other major markets, this latest patent for emulsification covers a range of formulation versions which includes both the Berol® 6446 Heavy Sulphur Fuel Oils (HSFO) emulsifiers and Sulnox Eco™ Fuel Conditioners which enhance all diesel, petrol/gasoline and biofuels, and marine fuels including Marine Gas Oil (MGO) and Marine Diesel Oil (MDO), Very and Ultra Low Sulphur Fuel Oils (VLSFO/ULSFO) and HSFO. 

Australia is a significant new patent for Sulnox, as the company continues to expand its global reach into the southern hemisphere in partnership with major distributors, and opens new stock locations. The Australian market's longstanding connections to South East Asia, where Sulnox has become well established, also reinforce the potential for supporting Australia's major industries and their closest supply chains.

Sulnox believes the new patent will accelerate development of revenue opportunities in Australia. The maritime sector, in which the company has achieved significant early success globally, is fundamental to Australia's economy, contributing A$203 billion (£101 billion) to GDP in 2023; the country has approximately 70 ports handling 98% of all trade by volume that flows in and out of its borders (Source: Australian Institute of Marine Science, 2023). In addition, the mining sector, which is equally under regulatory pressure to reduce fuel costs and emissions throughout its supply chain, is an even larger segment of Australia's economy, contributing almost 10% of GDP (Source: Reserve Bank of Australia).

Ben Richardson, CEO of Sulnox, commented: 

"Our Australia patent is critical intellectual property as we focus on his very sizeable market. Sulnox has identified several opportunities among large industrial players struggling to meet tough sustainability goals while working hard to reduce fuel costs. Supported by evidence of growing adoption in leading shipping businesses and other industrial settings, we are encouraged by the potential to deploy our zero-capex solutions at scale in the across the world's largest island continent."
