Alternative fuels
In the field of alternative fuels, RAPTECH offers a solution for the production of (marine) fuel emulsions based on homogenized bunker fuel oils (HFO | HSFO | VLFO | ULSFO) or renewable biofuels with its innovative cavitation technology and the CaviFlow® Plug&Play module. The Future Fuel blends are low-consumption and environmentally friendly thanks to a significant reduction in emissions of up to 25%. The bunker fuel emulsions naturally meet the ISO 8217:2024 requirements.
Maintain systems - reduce emissions. The effective blending of biofuels with traditional fossil fuels using the CaviFlow® inline module is an economically viable measure for reducing greenhouse gases without the need for a high investment and conversion budget. Fuel emulsions do not require any changes to engines, on-board fuel supply systems or within the bunker infrastructure. Their blend ratio is adaptable depending on the season.
Another advantage: the reduced fuel consumption means that IMO emission standards are met and shipping companies have to purchase fewer certificates under the EU Emissions Trading System (EU ETS).

Immediate use
CaviFlow®
CaviFlow® inline modules are flexibly scalable for flow rates of up to 100 m3/h. With thread or flange for plug & play use in existing systems.
No moving components are used inside the module - for minimum maintenance and maximum operational reliability.
More complete combustion
Reduced emissions through alternative fuels
Fuel emulsions mixed with the CaviFlow® inline module have significantly lower emissions - thanks to their improved combustion efficiency, lower flame temperature and higher oxygen content. This is due to the component mixture and the ultra-fine homogenization of the fuel oils by means of cavitation treatment.
The reduction of emissions is becoming increasingly important in the context of emissions trading systems such as the EU Emissions Trading System (EU ETS). With maritime fuel emulsions using cavitation technology, shipping companies can comply with current IMO emission standards and advance their sustainability goals - without high retrofitting costs.
- 25% reduction in NOx and SOx emissions
- 30% reduction in particulates and carbon dioxide (CO₂)
- Fewer fees for emission certificates

Cost savings
Sustainable fuel consumption through alternative fuels
The improvement in fuel atomization and combustion efficiency using cavitation technology in the CaviFlow® Plug&Play module also leads to lower consumption of fuel emulsions. The lower residues are also due to the ultra-fine homogenization of the fuels and the sensible combination of fuel components.
- Protects the environment
- Minimizes energy costs
- Requires fewer EU ETS emission certificates
Reduce emissions - maintain systems
Retention of the on-board fuel systems
Adding biofuels to fossil fuels and homogenizing them using cavitation technology is an economically viable measure for reducing greenhouse gases. Unlike new alternative fuels, the CaviFlow® inline module does not require a high investment and conversion budget. The modules can be easily integrated into existing systems via a flange or threaded connection. Maintaining the existing on-board fuel systems and bunker infrastructure in shipping offers decisive advantages:
- Low investment costs: ships are already equipped with all the necessary components such as fuel processing units and pipelines that work with traditional fuels
- On the port side, there are globally established and globally available logistics for the bunker supply of traditional fuels. By using existing systems, costs can be avoided and a high level of supply security is guaranteed
- In addition, traditional fuel systems are characterized by their technological maturity and high operational reliability. This not only reduces the technical risk during operation, but also facilitates maintenance and spare parts supply
Clean facilities
Reducing operating costs with alternative fuels
Alternative fuels blended with the CaviFlow® Plug&Play module offer further tangible cost savings. Their clean combustion extends the maintenance intervals of engines and technical systems, which suffer less from contamination caused by sludge and carbon deposits.
- Reduced smoke and soot formation
- Improved lubricity
- Less contamination in engines and systems
Environmentally friendly
Alternative fuels without additives
Without the addition of harmful additives such as emulsifiers, surfactants or polymers - the alternative fuel emulsions produced with the CaviFlow® inline module are characterized by their environmental friendliness.
However, additives can be added at any time depending on customer requirements.
- Chemical additives worsen the combustion properties
- Additives increase the process parameters and therefore the operating costs
- Additives pollute the environment
However, additives can be added at any time depending on customer requirements.
Seasonally adaptable
Flexible mixing ratio of RAPTECH alternative fuels
The blend ratio of the fuel emulsions mixed with the CaviFlow® inline module is flexible and seasonally adaptable - and of course ISO 8217:2024 compliant. This ensures a number of strategic and operational advantages, especially in shipping with changing environmental and operating conditions:
- By specifically adjusting the mixing ratio with the CaviFlow® Plug&Play module , the ignition quality, viscosity or oxygen availability can be optimized - depending on the outside temperature or engine load
- Inexpensive components (e.g. biofuels, by-products) can be added flexibly depending on availability and without being dependent on price fluctuations
- In the event of stricter environmental regulations or journeys through emission control areas (ECA), the proportion of low-emission components can be increased depending on the situation.
Available worldwide
Safe transportation and storage of alternative fuels
Fuel emulsions produced with the CaviFlow® inline module are extremely stable. This means they can be stored, pumped and transported at much lower temperatures compared to conventional HFO.
Due to their global and widespread availability, there is also no risk of supply bottlenecks in remote ports - in contrast to new alternative fuels, for which the infrastructure is still being developed.
- Emulsion fuels easily dissolve in water in the event of a leak
- This prevents major environmental damage
- Easier solubility makes handling safer for personnel
