Not too long ago I printed a roundup of fairly terrible hydrogen maritime trial efforts, and ended with a request that if others knew of extra, they need to share. Just a few further ones bubbled up and there have been a few minor corrections and pleasant additions. I encourage those that haven’t learn the earlier article to take action by way of the hyperlink above after which learn this text.
Let’s return to the topic of a lot of the evaluation within the current article, the MF Hydra. As a reminder, it will get its hydrogen from 1,300 kilometers away in Germany. It’s really a barely longer journey than Google Maps urged, as you’ll be able to’t drive liquid hydrogen vehicles by means of most tunnels in Europe due to the hazards, so it has to detour round Hamburg. The mix of the 4 truckloads driving a minimum of two days in every route — ferries have strict necessities and restrictions round liquid hydrogen vehicles, so it’s fairly attainable that they may face delays there as properly — the upper carbon electrical energy used to make the hydrogen in Germany, and the leakage of excessive world warming potential hydrogen by means of the worth chain signifies that the ferry is emitting twice as a lot greenhouse fuel properly to wake because the diesel ferry it replaces, and at roughly ten occasions the price of power because the roughly 80 battery electrical ferries which can be crossing Norway’s fjords already.
However a commenter identified one other amusing level, which is that the gas cells can’t ship as a lot energy because the batteries on an electrical ferry which operates on precisely the identical triangular route between three small ports in western Norway. Because of this, it does the identical journey however slower. Ten occasions the associated fee, about 40 occasions the emissions, and it will probably’t even do the identical job. Par for the course for hydrogen primarily based on my evaluation of fleets globally. They promote it as being precisely the identical as fossil fuels with no operational adjustments required and having superior traits to batteries, and that’s simply not true.
However the Hydra wasn’t Norway’s first foray into bedragssløsing (a Norwegian compound phrase I had ChatGPT make up for me combining deception and waste). The Beffen hydrogen ferry challenge in Bergen, Norway — a city a few hundred kilometers, six ferry rides, and 37 hours journey north of the Hydra’s failures, launched in 2009. It was an try to combine hydrogen gas cell expertise into one of many metropolis’s historic passenger ferries. The challenge confronted the same old important challenges, together with restricted refueling infrastructure, storage and security considerations, and gas cell sturdiness. These obstacles, mixed with excessive operational prices and technological limitations that proceed to face hydrogen transportation makes an attempt right this moment as a result of they’re systemic and unattainable to beat, led to the challenge being deserted in 2016. Regardless of its failure, Norway wasted extra money on the MF Hydra, which goes to be deserted for a similar causes within the to not distant future.
Then there’s the 30-meter, solar-panel, wind-turbine, kite-sail, and electrolyzer-toting Power Observer catamaran. It accomplished a seven-year journey world wide lately. Launched in 2017 and retrofitted from a former racing catamaran, the vessel traveled throughout 50 international locations and 101 ports. It produced some hydrogen from seawater by means of onboard electrolysis. Now again in its residence port of Saint-Malo, France, the vessel continues to function an academic platform — i.e., it’s moored, not going wherever, and children get faculty journeys to it.
You would possibly discover I used the modifier “some” earlier than hydrogen there. The large declare they make is that over the seven years they produced 1.3 tons of hydrogen on board from seawater. That’s half a kilogram a day on common. Below completely calm situations and excellent situations with no hull fouling and good propellers, which may be capable to present 5 kilometers of vary. That’s not precisely an enormous contributor. Extra seemingly it was used for onboard methods just like the radio and induction range. In fact, it had batteries too, 112 kWh of lithium-ion batteries. That half kilogram of hydrogen may have been saved as electrical energy with none of the absurd losses with 95 kWh to spare.
In the event that they’d ripped out the electrolyzer, compressors, hydrogen storage tanks and gas cells, which weighed 1.5 tons and occupied 5 cubic meters, they may have put one other 300 kWh of storage in there for the mass and had 4.4 additional cubic meters to play with, which might have been way more helpful. Assuming they may have stuffed the batteries, they may have traveled about 180 kilometers on the 300 kWh. Regardless of this actually apparent mass, quantity, power and stability distance, folks do preserve pointing on the Power Observer as being hydrogen powered, when in precise reality it simply wasted a number of generated electrical energy making hydrogen and never getting a lot for it.
The Power Observer isn’t the one try to do that. The Race for Water is a 35-meter-long hydrogen-powered catamaran retrofitted from the PlanetSolar, remodeling it right into a hybrid renewable power vessel combining photo voltaic panels, a hydrogen gas cell system, and a kite sail for wind propulsion. It confronted the same old challenges resembling restricted hydrogen infrastructure, storage constraints, and sophisticated upkeep necessities which hindered its effectivity throughout a few world expeditions. The Race for Water Basis is sensibly transitioning to the MODX 70, a zero-emission vessel powered by superior hydrogeneration and wind propulsion methods, fully abandoning hydrogen in favor of a extra streamlined and sustainable power design. Plenty of batteries, no hydrogen, par for the course for individuals who strive it.
Then there’s the MARANDA challenge, funded with $3.1 million from the EU’s Horizon 2020 program, which aimed to exhibit the viability of hydrogen gas cell methods in maritime purposes. Put in aboard the analysis vessel Aranda, the system supplied 165 kW of energy for auxiliary methods and dynamic positioning, changing standard diesel turbines. The challenge confronted the same old important challenges, together with restricted refueling infrastructure, the sturdiness of proton trade membrane gas cells in harsh marine environments, and the excessive value of hydrogen manufacturing and storage. The MARANDA challenge stopped in 2022, having confirmed but once more that hydrogen is de facto unhealthy for this use case, however claiming success.
Subsequent up is the Viking Neptune cruise ship, delivered in November 2022. It has a small 100 kW gas cell designed to energy a portion of auxiliary methods resembling lighting and air flow. It’s explicitly experimental, as a result of as soon as once more they haven’t checked out all the experiments already achieved that discover that batteries are vastly superior in just about each means.
Then there are the in-progress efforts by individuals who refuse to study from historical past. There’s the With Orca, which is bulk service developed by means of a collaboration between HeidelbergCement and Felleskjøpet Agri. The 88-meter bulk service may have compressed hydrogen saved onboard and options two rotor sails for wind-assisted propulsion. Apparently they’ve a minimum of realized that gas cells and ocean air don’t combine, so that they as a substitute are going to be utilizing even much less environment friendly inside combustion engines. It was purported to enter service early this 12 months, however naturally there’s no option to refuel the factor, so governments have ponied up $9.3 million to construct infrastructure that can find yourself being deserted as prices escalate and the truth of hydrogen’s leakage charges and excessive greenhouse fuel standing change into obvious. They’ll undoubtedly declare success regardless.
Again to Norway and ferries. Norway is investing $550 million to construct and function two hydrogen-powered ferries on the 100 kilometer, open seas, Vestfjorden route for 15 years, with development prices estimated at ~$276 million USD per vessel—as much as 4 occasions increased than the $60–100 million USD typical for diesel or LNG ferries. In contrast, battery electrical ferries sometimes value 30% to 40% greater than fossil gas powered equivalents. The ferries might be equipped with 5–6 tons of inexperienced hydrogen day by day from GreenH AS below a 15-year settlement, with the hydrogen produced by way of electrolysis powered by renewable power. Definitely given the situation within the far northwest of Norway, the hydrogen must be shipped in at extraordinary expense. Substantial authorities subsidies, together with Enova SF’s $68.3 million for hydrogen infrastructure, goal to offset the upper prices of hydrogen vessels and their refueling methods. Mainly they will be throwing away two-thirds of the electrical energy that they may have been placing into way more dependable batteries, all within the identify of offering extra dependable transport. I don’t assume it will finish properly. Anticipate tales about missed sailings, excessive bills, failed refueling and excessive hydrogen greenhouse fuel emissions.
Within the bizarre annals of hydrogen on the excessive seas, it’s time for a dictator’s yacht. The Hydrogen Viking is a reported challenge to remodel a 28-meter Sunseeker Predator 95 yacht, previously owned by Muammar Gaddafi and named Che Guevara, right into a hydrogen-powered vessel. After being grounded in Malta and left deteriorating, the yacht was acquired by Norwegian shipbuilder Inexperienced Yacht. Three years after the announcement, it’s apparently nonetheless deteriorating someplace. I’m not ready with bated breath for it.
The Finnøy Hydrogen Ferry Mission is — or perhaps was — an initiative by Norwegian operator Norled to switch biodiesel with hydrogen gas on a ferry serving the Finnøy route, northeast of Stavanger. The challenge is a part of the EU-funded FLAGSHIPS initiative — extra money wasted by the EU attempting to make hydrogen match for goal for transportation —, which goals to deploy two hydrogen-powered vessels: one in Stavanger, Norway, and one other in Lyon, France. Naturally, it will probably’t get hydrogen. In January 2020, Enova, a Norwegian authorities enterprise, allotted $1.3 million to help this conversion and an extra $2.2 million for the event of a hydrogen manufacturing and bunkering facility at Fiskå. This facility is deliberate to provide roughly one ton of hydrogen per day, with half designated for the ferry’s operations. As of December 2024, the ferry operates on biodiesel, with the hydrogen conversion pending additional technical and financial evaluations, that means it’s unlikely to ever occur given the truth of prices.
Havila Voyages operates 4 hybrid cruise ships—Havila Capella, Havila Castor, Havila Polaris, and Havila Pollux—that mix LNG engines with giant battery packs, enabling as much as 4 hours of zero-emission operation in delicate fjords. The ships are designed for future conversion to hydrogen gas as a part of the FreeCo2ast challenge, funded by Norwegian organizations, together with Enova and the Analysis Council. Havila goals to transition to renewable biogas by 2028 and hydrogen by 2030 to adjust to Norway’s 2026 ban on fossil-fuel-powered vessels in protected fjords. What’s actually going to occur is that they may transition to biogas, however they’ll positively put in a lot larger batteries. Hydrogen? Not going. In fact, luxurious cruise ships have a lot increased margin than most maritime use instances, so perhaps they’ll waste the cash.
Ulstein, a Norwegian shipbuilding firm that’s an innovator in hull design with its X-Bow, has developed the ULSTEIN SX190 Zero Emission design, a theoretical 99-meter-long offshore development help vessel powered by hydrogen gas cells. As of December 2024, the vessel stays within the design section, with no stories indicating that development has commenced. Ulstein had projected that sea trials may start as early as 2022. That clearly didn’t occur and is unlikely to ever occur. As a reminder, hydrogen isn’t zero emission because it leaks in every single place alongside the worth chain and has a excessive world warming potential.
To be honest to Ulstein, a agency I like an ideal deal for the X-Bow, the leakage charges have been hypothetical from first ideas till lately when peer-reviewed research began measuring it, and the excessive world warming potential can be comparatively new information, with the Nature paper discovering 13 to 37 occasions the efficiency of carbon dioxide over 100 and 20 12 months time frames solely popping out in 2023. With luck and somewhat cautious effort by rational power actors, these papers and their implications will get in entrance of funding companies in order that hydrogen could be put again the place it belongs, in industrial amenities as a rigorously managed feedstock.
The Østensjø Rederi Offshore Wind Service Vessel (OWSP) is one other reported Norwegian hydrogen-powered ship meant to help offshore wind farm operations. As of now, particular particulars relating to the vessel’s development standing, operational timeline, and technical specs haven’t been publicly disclosed. The event of hydrogen infrastructure and expertise will play a vital function within the challenge’s development, that means it’s unlikely to ever hit water both. The transport trade is rather like each different inexperienced hydrogen for power market, stuffed with bulletins which by no means move closing funding determination. Individuals pushing hydrogen fill their decks with bulletins, however by no means point out that they don’t and sure gained’t exist.
Samskip, a European logistics agency, is pushing forward with two hydrogen-powered transport initiatives regardless of uncertainty attributable to the monetary troubles of its accomplice, TECO 2030. The SeaShuttle challenge entails establishing two 135-meter container ships with 3.2 MW hydrogen gas cells, set to function between Oslo and Rotterdam by late 2025. Individually, the HyEkoTank challenge plans to retrofit the multipurpose vessel Samskip Kvitnos with hydrogen gas cells to fulfill EU and Norwegian “zero-emission” rules. Nonetheless, TECO 2030, chargeable for offering the hydrogen expertise, filed for chapter in November 2024, elevating considerations about challenge timelines.
Moss Maritime, a subsidiary of Saipem, has developed a liquefied hydrogen containment system impressed by its established spherical LNG tank design. The corporate has acquired Approval in Precept from DNV for its LH₂ containment system. Nonetheless, no vessels utilizing this expertise have been constructed or entered operation up to now. And none seemingly will, as everybody now realizes what was apparent to anybody who did the maths with actual numbers years in the past knew, which is that power that prices ten occasions what LNG prices isn’t reasonably priced to any nation’s financial system.
In November 2020, DFDS introduced plans to develop a hydrogen-powered ferry, Europa Seaways, for the Oslo–Frederikshavn–Copenhagen route. The vessel, designed to hold 1,800 passengers and as much as 120 vehicles or 380 automobiles, would characteristic a 23 MW hydrogen gas cell system, with gas sourced from a wind-powered electrolyzer in Copenhagen. Initially projected to enter service by 2027, there have been no important updates on development or funding progress as of December 2024, leaving the challenge’s standing unsure. Useless within the water, extra seemingly, as value realities reared their ugly heads.
The pattern, by the best way, may be very clear, with a fairly overwhelming majority of hydrogen transport initiatives being in Norway. Odd how a fossil gas main is attempting to actually laborious to make molecules for power stay a factor, particularly after they have 80 electrical ferries cheaply, effectively and reliably plying their waters already.
