The company is also collaborating with the French government and industry, but above all the driving force comes from the Italian Navy \u2014 Fincantieri\u2019s biggest military customer.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cThe Italian Navy is very conscious of the need to reduce the use of fossil fuels, even if international regulations on cutting emissions only concern civil vessels,\u201d Debenedetti said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Biofuels are part of an ongoing study led by Fincantieri-owned propulsion firm Isotta Fraschini Motori, which aims to develop a marine engine that can use either traditional fuel, liquid natural gas, ammonia, hydrogen or biofuel.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cApart from biomass and food waste, biofuels can derive from crops which are not fit for consumption,\u201d Debenedetti said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But ammonia \u2014 another possible alternative to fossil fuels \u2014 is the \u201ctoughest challenge,\u201d he added. \u201cWhen burned it produces energy, but storing it is hard and igniting it is hard.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If biofuel has short-term potential, the longer-term challenge Fincantieri is working on is creating hydrogen-powered fuel cells for surface vessels that are similar to those used on submarines today.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cThe technology is mature, but not ready for use on ships at the proper scale. Whereas you might need them to generate 100 kilowatts on a submarine, you will need tens of megawatts on a surface vessel,\u201d Debenedetti said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A three-year joint study launched last year by Fincantieri, France\u2019s Naval Group and their joint venture Naviris, with funding from the French and Italian defense ministries, is exploring how fuel cells can be put onboard a warship.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cIt comes down to making the system anti-shock and making it fit into limited space,\u201d Debenedetti said. \u201cFuel cells take up more space than traditional propulsion, not least because of the hydrogen storage. And while on a passenger ship I might remove cabins to make room for it, I cannot on a naval vessel.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Another study, this time with a eye on both the civilian maritime market and the defense sector, aims to progress Zeus, a program to build a 25-meter, 170-ton experimental ship to test fuel cell technology. Now under construction at Fincantieri\u2019s Castellammare di Stabia yard near Naples, Zeus involves input from Isotta Fraschini Motori and is funded by Italy\u2019s Economic Development Ministry.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Fincantieri believes its work on technologies for both the civil and military sector will give it an industrial advantage. \u201cPeople working on both sides can swap information \u2014 the learning curve on the civil side benefits our defense work,\u201d Debenedetti explained.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It is the same kind of synergy that saw Fincantieri use its work on passenger comfort onboard cruise ships to <a href=\"https:\/\/www.defensenews.com\/naval\/2018\/05\/30\/we-spent-3-days-on-a-top-ffgx-contender-heres-what-you-need-to-know\/\" target=\"_blank\">improve<\/a> the lives of sailors on its FREMM warships \u2014 a factor that <a href=\"https:\/\/www.defensenews.com\/industry\/2021\/05\/21\/fincantieri-dedicates-all-its-us-shipyards-for-navy-frigate-orders\/\" target=\"_blank\">convinced the U.S. to buy the frigate<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Likewise, work to reduce noise and vibration on military vessels was used on cruise ships.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When it comes to lowering environmentally unfriendly emissions, the pressure is felt more in the civil sector, where the European Union is pushing member states to go green.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">On July 26, Fincantieri, energy company Snam and cruise ship-operator MSC signed a memorandum of understanding to jointly build a zero-emission, hydrogen-powered cruise ship.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cIt could be achievable by the start of the next decade, probably using fuel cells which are more efficient although more expensive and larger than a hydrogen internal combustion engine,\u201d Debenedetti said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Another alternative to fossil fuels, liquid natural gas is already a mature technology for cargo ships, he said, \u201cbut refueling is the issue: In the Mediterranean, the only port with LNG refueling is Barcelona.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Even if military ships don\u2019t face regulatory pressure to reduce fuel consumption, there is a real need to use power sparingly, as new radars and laser weapons suck up enormous amounts of energy onboard.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That has prompted another study, this time funded by the Italian Defence Ministry, to look into the use of direct current electricity onboard ships, as opposed to the more usual alternating current.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cDC allows you to manage high loads of electricity better over a short time,\u201d Debenedetti said.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Of all the alternative fuels touted as future solutions for cleaner warships, one of Europe\u2019s shipyards is
