A UK company with a background in the Venezuelan oil industry is developing a marine fuel blend that cuts emissions by up to 30% in existing ships' engines — and will have been tested by the two biggest container lines.

Quadrise first demonstrated a marine version of an oil-in-water emulsion fuel that was cheaper and cleaner than heavy fuel oil in 2012.

Its Multiphase Superfine Atomised Residue (MSAR) fuel is produced using 70% oil residues with 29% water and less than 1% of chemical additives.
