MSAR®
Our MSAR® technology produces a low viscosity oil-in-water emulsified synthetic fuel oil or biofuel. It is a proprietary technology to mix the heaviest residual oils available with small amounts of specialist chemicals and water to a bespoke formulation. The resulting MSAR® emulsion contains approximately 30% water and less than 1% chemicals. The emulsion is a low viscosity fuel at room temperature, which makes it easier to handle and reduces the heating costs for storing, transportation and use in comparison to heavy fuel oil (HFO).
In addition, our MSAR® technology pre-atomises oil (or bio-oil) droplets within the emulsion and makes them 10-20 times finer than the droplets formed from atomising liquid fuels; this means that MSAR® burns almost completely with a white plume, like a gas.
There is virtually no particulate “black carbon” in the exhaust with a cleaner burning flame, making it more environmentally friendly to use.
The technically superior “pre-atomised” MSAR® fuel has enhanced combustion features that lead to efficiency benefits compared with conventional residual fuels applications such as marine, industrial applications and thermal power generation.
THERMAL POWER GENERATION & INDUSTRIALS
Oil-in-water emulsion fuels such as MSAR® have been used extensively in power plants and industrial applications, with over 60 million tons used globally and the Quadrise team responsible for the majority of projects:
More recently MSAR® has been used successfully on a 300MW power plant in Lithuania (case study below) and an industrial application in Morocco on a 33MW industrial furnace.

MARINE DIESEL ENGINES
Following the proven experience of using oil-in-water emulsion fuels for over 150,000 hours in medium-speed 4-stroke Wärtsilä diesel engines for 150MW base load power generation, Quadrise have been pioneering the use of MSAR® in larger low-speed 2-stroke diesel engines with shipping majors, engine OEMs and class societies.
Testing of marine MSAR® has progressed rapidly from the laboratory, to stationary engine tests and commercial vessel trials.
Other than lower energy costs to start with, MSAR® has proven to provide lower Specific Fuel Oil Consumption (SFOC) as demonstrated on Wärtsilä Flex engines, leading to lower operating costs and associated CO2 savings of up to 9%.
Similar engine efficiency improvements have been experienced during testing on a Wärtsilä 4-stroke 32 engine at higher loads:
The 30% water content of MSAR® delivers lower NOx emissions of up to 45% at higher loads versus HFO and marine gasoil (LFO). This was first demonstrated on a 4-stroke Wärtsilä Flex 60 test engine and then repeated on the main engine (69MW 12-cylinder Flex 96) of a seagoing vessel.
Our experience in 2-stroke engine follows our commercial experience in other applications showing that MSAR® has a highly efficient combustion and carbon burnout, as a result of the micro hydrocarbon droplets in MSAR®, reducing ash and black carbon emissions as well as lower total hydrocarbon emissions compared with conventional marine fuels:
