WÄRTSILÄ, ABB AND RINA LEAD PROJECT FOR VIABLE HYDROGEN FUEL SOLUTION

WÄRTSILÄ, ABB AND RINA LEAD PROJECT FOR VIABLE HYDROGEN FUEL SOLUTION

Thursday, November 25, 2021 

Wärtsilä, together with class society RINA, ABB, Helbio - a subsidiary of Metacon, the Liberian Registry, and an energy major have joined forces in an effort to deliver a solution with hydrogen as fuel, aiming to have a scalable and sustainable solution that will exceed the IMO 2050 target for a 70% reduction in carbon intensity without the need for an extensive infrastructure investment.

Wärtsilä believes this offers the shipping industry a pathway to low-carbon operations within a reasonable time frame. Current difficulties and cost considerations regarding the production, distribution, and onboard storage of hydrogen have so far limited the sector’s interest in its direct use as a marine fuel. However, by producing hydrogen onboard, and using readily available LNG, the solution is considered to become far more viable and in a much faster time than would otherwise be possible.

Lars Anderson, Director, Product Management and Sales Support, Wärtsilä Marine Power, said: “Our gas engines are already able to use mixtures of hydrogen and LNG, and our future efforts will be to reach 100% hydrogen fuel. We are totally committed to supporting in every way possible the decarbonisation of shipping operations. This project is one more example of this commitment, and we are very pleased to be partnering with other stakeholders to make the IMO 2050 target achievable. This project will give owners a real chance to stay ahead of the competition in terms of efficiency and sustainability.”

The concept is based on combining LNG with steam to produce hydrogen and CO2. The hydrogen produced will be used directly in a mix with natural gas in internal combustion engines or in fuel cells, thus eliminating the need for hydrogen to be stored onboard. The CO2 will be liquefied using the cryogenic stream of LNG that would be used as fuel anyway, and later disposed ashore for carbon storage. Tankers can use the stored CO2 as inert gas during discharge.

The necessary equipment can easily be fitted on the deck of a commercial vessel. This concept will support the marine sector’s gradual transition from LNG to hydrogen, without any major adjustments to a vessel’s onboard technologies.

Only LNG bunkering will be required and, by progressively increasing the production of hydrogen, the consumption of fossil methane and associated methane slip will be reduced at the same rate.

Wärtsilä and ABB will support the application of hydrogen in powering internal combustion engines and fuel cells respectively, while Helbio will provide the technology and manufacturing of gas reformers. RINA and the Liberian Registry will provide advice and guidance on the application of rules and regulations for novel concept alternative designs, based on Hazid/Hazop analyses, as well as specific rules for this kind of arrangement.
