Market applications


The methanol fuel cell technology provides a green alternative to the maritime sector addressing the worldwide focus on cutting down CO2 emission and reducing air pollution. 

Decarbonising the maritime sector

Methanol fuel cells

Enabling a green maritime sector

A methanol fuel cell system enables a truly green operation within the maritime sector providing net-zero carbon emission and zero particle outlet. 

The methanol fuel cell is a flexible power solution that can be used for auxiliary power or propulsion depending on ship type and customer needs. Due to its flexible form, the system is adaptable in regards to space availability and placement on the ship.

The fuel cell technology is applicable for both smaller gensets as well as larger auxiliary power units in the megawatt range. 

Accelerating the maritime market

Every year, the shipping sector is responsible for about three per cent of the world’s greenhouse gas emissions. Blue World Technologies aims to accelerate the green transition of the maritime market by developing a fuel cell-based APU system that runs on methanol.

Blue World Technologies methanol fuel cell solution can deliver the electricity required on board, utilizing a simple and modular cabinet configuration which consists of 200 kilowatt cabinets that, when combined, can produce an energy load in the megawatt range. 

This implies that the energy supply can be modified to meet the needs of customers. Blue World’s methanol fuel cell APU system will have an energy efficiency of 45 to 60 per cent to compensate for the green premium of e-fuels, such as methanol. This will reduce operating expenses and allow a more cost-effective use of e-fuels.

No gas clean-up

The fuel cells are based on high-temperature PEM technology (operating at 160-180°C) that has a high resistance to impurities which means that no gas purification is needed on the reformat gas.

waste heat utilisation

Unique for the HT PEM fuel cells is the potential for waste heat utilisation where part of the waste heat from the fuel cell is used to drive the process of reforming methanol and thereby optimising the total system efficiency. Furthermore, waste heat can also be used for additional energy recovery.

Market and product match

Fuel cells to make a difference for the maritime sector

With a cutting-edge technology platform based on high-temperature PEM technology, the Blue World Technologies methanol fuel cells provide a strong alternative to conventional gensets and auxiliary power units for marine usage.

Depending on ship type and available space, the fuel cell system can be in a cubic shape similar to a conventional motor block or in a flat pack configuration. Both can be stacked according to the required power output. Regardless of system size, the fuel cell system enables new opportunities for placement of the power unit onboard the ship ensuring optimal space utilisation.

The HT PEM methanol fuel cells are combined with methanol-reforming ensuring a simple system design with high energy conversion, efficiency, and system power density. 

As the fuel cells have no moving parts, system maintenance is significantly reduced, and preventive maintenance is very low and limited to air filter change and basic inspections. The modularity of Blue World Technologies’ fuel cell system enables optimised redundancy while advanced monitoring ensures a predictive operation.

Benefits for the market

With a worldwide focus on finding alternative power solutions for the maritime industry the methanol fuel cell technology provides multiple benefits making the technology a strong candidate.

Reduced maintenance

Significantly reduced maintenance due to no moving parts and preventive maintenance is limited to basic inspections and air filter change. The methanol fuel cell system provides advanced remote system monitoring enabling a reliable operation.

A green marine fuel

Sailing on methanol

Methanol is already an existing and widely recognised fuel within the maritime industry, and when running on methanol produced from renewable sources, the operation is CO2 neutral from a well-to-wheel perspective. Additionally, the methanol fuel cells eliminate NOx, SOx, and particle emissions ensuring an environmentally friendly operation.

As a liquid fuel at atmospheric pressure, methanol is a fuel that is simple to handle and can be stored in large volume. Compared to alternatives, such as batteries and hydrogen, methanol has the advantage of the fuel storage density being much higher.  Methanol is already widely available in the majority of the largest ports around the world making methanol a strong candidate as an alternative to fossil fuels.
