South Korea patent further strengthens Asia presence

(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 South Korea.

Consistent with Sulnox's more than 100 patents granted to date in other major markets, this latest patent for emulsification covers Heavy Sulphur Fuel Oils (HSFO) 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. 

South Korea is a significant new patent for Sulnox, as the company continues to expand its global reach into Asia in partnership with major distributors, and opens new stock locations. The country's proximity and connections to key centres such as China and Japan, both of which have granted patents to Sulnox, also reinforce the potential for supporting Asia's major industries and their closest supply chains.

The South Korean government's national decarbonisation strategy further underlines the relevance of Sulnox's innovation. Under the South Korean Green New Deal and its legally binding commitment to achieve net zero by 2050, South Korea has placed strong emphasis on emissions reduction across transport, shipping and heavy industry, supported by green finance, regulatory incentives and rapid deployment of clean technologies. As part of this transition, the country continues to expand the use of biofuels and blended fuels, particularly within road transport and marine applications, as an interim and pragmatic pathway to reducing carbon intensity as alternative energy systems scale.

While increased biofuel blending supports South Korea's climate objectives, higher blend ratios can present practical challenges relating to fuel stability, oxidation, water absorption and long-term storage, particularly for large industrial operators and fleet-based users. Sulnox Eco mitigates these effects by conditioning blended fuels to maintain stability, combustion efficiency and compliance under demanding operational conditions, thereby supporting emissions reduction without compromising engine reliability or fuel performance.

Ben Richardson, CEO of Sulnox, commented:

"South Korea is one of Asia's most sophisticated and policy-driven energy transition markets. With strong government backing, advanced industrial operators and ambitious net-zero targets, it is an environment where practical, scalable solutions such as ours can deliver immediate impact. Strengthening our intellectual property position supports our ambition to work alongside Korean industrial leaders as they pursue emissions reduction at pace, while also addressing rising fuel costs. We see a significant opportunity to deploy Sulnox's zero-capex technology across transport, marine and industrial sectors as part of South Korea's green transformation."
