The maritime industry has paid more effort to accelerate the energy transition to hydrogen as a marine fuel. Lately, the global leader in energy and marine markets, Wärtsilä has collaborated with class society RINA and other stakeholders, to apply hydrogen as fuel as soonest.
The project target is to achieve the reduction in GHG emissions by 2050 without investing too much in extensive infrastructure onboard vessels. As a result, the lead time to use hydrogen as a marine fuel will be shortened and the shipping industry will soon have a way for low-carbon operations.
Furthermore, Lars Anderson from Wärtsilä, “Our gas engines are already able to use mixtures of hydrogen and LNG, and our future efforts will be to reach 100% hydrogen fuel,“. So the parties are trying to support the marine sector’s energy transition process without a major change in vessel technology and at a reasonable price as well.
Lars Anderson also added that the company is ready to support the decarbonization of shipping operations in any way
The other stakeholders include ABB, Helbio, a subsidiary of Metacon AB, the Liberian Registry, and an energy major.
The concept from LNG to hydrogen fuel
Due to H2 characteristics, hydrogen is recognized as a high potential alternative fuel with low to zero carbon emissions. While hydrogen is the highest energy content per mass, which means it can increase the energy efficiency and low consumption of engines, but the hydrogen in return needs more space to be stored and strictly low temperatures below -253° C (-423.4° F) to liquefy.
The vital way in the project here is producing hydrogen onboard and using readily available LNG.
The concept is based on combining LNG with steam to produce hydrogen and CO2. The hydrogen will be used directly in a mix with natural gas in internal combustion engines or in fuel cells. Thus, this is eliminating the need for hydrogen storage onboard.
The CO2 will be liquefied using the cryogenic stream of LNG that would serve as fuel anyway. Or CO2 can be used in the inert process. Later, it will be disposed of ashore for carbon storage.
The vessel will be geared up with the necessary equipment to carry out the process.
All parties team up to speed up the project
Wärtsilä and ABB will work on the internal combustion engines and fuel cells, ensuring the application of hydrogen to power vessels correctly.
Helbio will take its advanced role in the technology and manufacturing of gas reformers.
RINA and Liberian Registry cover the guidance on the application of rules and regulations for designs based on Hazid/Hazop analyses, as well as specific rules for this kind of arrangement and further provide advice during the project.
It’s worth reminding that the giant company Gazprom and government strategically carry out hydrogen energy development, implementing the roadmap for hydrogen usage.
