Laborious-to-abate sectors (heavy trade, metal, aviation) are more and more turning to hydrogen to comprehend decarbonization objectives, and maritime delivery isn’t an exception. Whereas interim decarbonization choices resembling liquefied pure gasoline (LNG) and gas mixing are presently obtainable, widespread adoption of zero-carbon fuels is the one path to achieve the Worldwide Maritime Group (IMO)´s latest decarbonization targets for 2040 and 2050.
Various Fuels are Important for Maritime Decarbonization
At present, fuels make up between 30%-50% of vessel working prices, and standard fuels account for as much as 99% of vessel vitality demand. There are a number of artificial zero-carbon alternate options to standard bunker gas, particularly ammonia and methanol. The manufacturing of those fuels stays a nascent, although quickly rising sector.
Incumbents and innovators are collaborating to deal with the manufacturing and storage/transport challenges that each ammonia and methanol current — resembling cryogenic and high-pressure storage techniques, high-energy manufacturing, engine innovation, and security issues (see A Good Storm for Maritime Sustainability). Maybe essentially the most vital hurdle to the worldwide scaling of those different fuels is price.
Inexperienced ammonia and e-methanol manufacturing is estimated at between 3 and 6 instances dearer than typical bunker gas, not making an allowance for extra transport and storage prices or vessel retrofits which may be required. Closing the fee hole between different fuels and standard fossil fuels is a vital step to be able to present an economically possible different gas choice to allow decarbonization.
Decreasing Various Gas Prices
The important thing to bringing down the price of future maritime fuels is inexperienced hydrogen, a key element within the manufacturing of each ammonia and methanol. To provide zero-carbon variations of those fuels (inexperienced ammonia and e-methanol), the hydrogen used for gas manufacturing should be zero-carbon as nicely. Though the long run gas combine situations are unsure, it’s clear that plentiful, low-cost inexperienced hydrogen might be important to fulfill the demand for zero-carbon fuels in addition to to cut back manufacturing prices sufficiently to permit for widespread market uptake.

Common Traits for H2-fuels Eventualities
Innovation: SunGreenH2
Innovators and maritime incumbents alike are collaborating to extend manufacturing and scale back the price of zero-carbon different fuels. SunGreenH2 is an fascinating innovator that simply appeared on the Cleantech Group 2024 APAC Cleantech 25 listing. The developer of an electrolyzer leveraging nanostructured supplies relies in Singapore. SunGreenH2´s electrolyzer system makes use of much less vitality than a traditional electrolyzer whereas producing as much as twice the inexperienced hydrogen output—and with out the necessity for valuable metals.
The corporate’s objective is to harness more and more plentiful and low cost renewable vitality and supply inexpensive inexperienced hydrogen to drive the vitality transition. The proprietary platform expertise and electrodes will also be utilized to different decarbonization applied sciences, together with gas cells, batteries, vitality storage, and solar-hydrogen panels. The primary industrial check of SunGreenH2´s electrolyzer expertise is presently underway at the side of Naturgy Innovahub in Spain.
Maritime Purposes
CEO & Co-Founder Tulika Raj notes that it’s important to supply a cheap method to harness emissions abatement to be able to meet maritime decarbonization targets. SunGreenH2´s modular, high-production system addresses this problem, decreasing the price of implementing on-site inexperienced hydrogen manufacturing each for different gas manufacturing and port operations.
The modular system requires about half the house of typical electrolyzer techniques, facilitating integration with on-site renewables and vitality storage. Modular, high-capacity hydrogen manufacturing allows refuelling of hydrogen and hydrogen-electric equipment, and may complement battery electrification, decreasing pressure on the grid, and enabling the electrification of industrial quality tools resembling cranes and forklifts.
