SulNOx, the green fueltech company delivering lower fuel costs and emissions, for zero capex, has secured a valuable new patent in Brazil.

It covers a range of versions of SulNOx conditioners which emulsify water, while increasing lubricity and oxygen availability to fuel, making it burn cleanly and more efficiently.

Brazil is an important new patent for SulNOx, representing validation in the world’s 10th largest economy (Source: IMF) and the largest country in South America by area and GDP. It is the world’s fifth largest by area and its seventh largest by population.

SulNOx expects the patent to support its pursuit of partnerships and collaborations with major industrial groups in the region. Coastal shipping links are critical to the Brazilian economy, connecting widely separated parts of the country, which has 36 deep-water ports.

In the mining sector, Brazil is among the largest producers of iron ore, copper, gold, manganese, tin and nickel, while the   the road system is the main carrier of freight and passenger traffic, marking a third major sector facing significant decarbonisation challenges and targeted by SulNOx.

In November 2025 the COP30 global climate change conference will be held in the Brazilian city of Belém.

Ben Richardson, CEO of SulNOx, commented:

“Our Brazil patent adds a huge and diverse economy to a growing portfolio. There are few countries with so many industries operating on a large scale, each pursuing tough sustainability goals on tight timetables. We are excited by the opportunity to work with a wide range of sectors to deploy our products at scale, helping organizations to save fuel costs and reduce emissions rapidly with our zero-capex solutions.”
