Quadrise, which develops low-emission fuels to help decarbonise shipping and heavy industry, has extended its exclusive global agreement with specialty chemicals group Nouryon until October 2026.

The deal ensures Nouryon will continue to exclusively supply the emulsifier chemicals used in the London firm’s MSAR® and bioMSAR™ fuel technologies.

The agreement also covers shared intellectual property linked to the development of these fuels.

Quadrise said the extension supports the ongoing rollout of its cleaner fuel solutions across shipping, power generation and industrial markets.
