For 3 years, the Worldwide Chamber of Delivery has been working a survey of ship house owners, protecting a number of domains, together with greatest dangers to transport, modifications in transport patterns with initiatives like friendshoring and most relevantly for this dialogue, decarbonization. Not too long ago they dropped their 2023-2024 survey, and the outcomes point out ongoing confusion amongst shipowners, in addition to lots of profitable lobbying and a few wishful pondering.
LNG as a transport gas is seeing declining assist, one of many higher notes from the outcomes. For these not paying consideration, burning methane in ship engines has been a giant enterprise for the previous 20 years. Along with the plain use in LNG tankers, itās taken the passenger ferry and cruise ship industries by storm, largely as a result of it doesnāt stink almost as badly as legacy maritime transport fuels when burned.
Sadly, the methane-burning advocacy teams have been challenged by it solely offering 20% to 30% carbon dioxide emissionsĀ in comparison with heavy gas oil, one thing that the shipowners acknowledge. Nonetheless, even thatās an overstatement, as thatās in a greater than finest case state of affairs.
Effectively-to-tank is problematic, as the worldwide pure fuel and LNG provide chain is leaky as a sieve, particularly in main exporting nations just like the US, Russia and Qatar. Whereas pure fuel may be extracted, processed, saved and distributed with minimal fugitive emissions, solely northern Europe has truly delivered on that promise by engineering in emissions-avoidance for the previous few many years. Because of this, upstream methane emissions are fairly excessive, whereas advocates have a tendency to advertise northern European ranges of emissions. Methane emissions, after all, are extremely problematic attributable to methaneās excessive international warming potential.
Liquifying pure fuel requires 8% to 12% of the embodied power, so upstream fugitive emissions are elevated by these percentages. And most liquification amenities burn pure fuel to create the electrical energy for liquification, so extra properly to tank emissions. Then thereās boil off. Higher operators reliquify extra boil off, however which means burning extra LNG to energy liquification.
And tank-to-wake isnāt almost as clear as marketed both. The Worldwide Council on Clear Transportation ran a two-year monitoring train, Fugitive and Unburned Methane Emissions from Ships (FUMES), which concerned utilizing trade normal methane detection expertise on smokestacks on the vessels within the examine. Whereas the trade was selling solely 3.5% methane slippage ā the share of the gas that was unburnt ā the ICCTās examine discovered a mean of 6.4%.
LNG is extra power dense by mass than heavy gas oil and has much less carbon in its make-up. Burning a ton of heavy gas oil (HFO) emits 3.1 tons of carbon dioxide, and the equal power of LNG solely emits 2.3 tons, which looks as if a win. However 6.4% slippage provides 1.6 tons of carbon dioxide equal (CO2e) to LNGās emissions, bringing it as much as 3.7 tons, properly above HFO. Thatās not a local weather win.
The trade has been swayed by lifecycle carbon evaluationās like Spheraās, which discovered 23% financial savings well-to-wake, however thatās not remotely reasonable. Whatās the provenance of that examine? It was commissioned by two organizations, SEA-LNG and SGMF (Society for Fuel as a Marine Gas) which clearly discovered a keen consultancy to jot down a report that gave them the outcomes they wanted to advertise their product.
Even the trade normal 3.5% slippage provides 0.08 tons of CO2e, which means that the āgoodā case is precisely the identical because the HFO base case. Thatās earlier than you add well-to-tank emissions. This isnāt a local weather win, itās a distraction by the fossil gas trade, therefore the purpose about profitable lobbying within the opening paragraph.
Ship operators like LNG due to it makes passengers happier and results in fewer complaints from ports and the cities that encompass them, so you possibly can see why itās taken off and why regardless of precisely zero local weather profit it stays probably the most extremely rated different power supply for transport for the following decade, not less than among the many 104 shipowners who responded in full to the survey.
Biofuels, an precise local weather answer, have been slipping too. In contrast to LNG, the place the advantages are vaporware, the slippage is probably going attributable to ongoing worldwide confusion about what constitutes sustainably manufactured biodiesel. In knowledgeable dialogue this morning, we have been shaking our heads over the EUās legislated distaste for cropped biofuels like soy beans or canola whereas concurrently contemplating reducing down virgin timber to pelletize for thermal power and electrical energy to be carbon impartial.
Jurisdictions within the USA like California are following down this foolish pathway as properly, primarily based on a mixture of things. The primary is the idea that massively extra biofuels than are at the moment manufactured could be required, which isnāt the case, however is quite common. Thatās primarily based on an assumption of a continuation of floor transportation requiring fuels when globally itās all going to impress, with slower geographies just like the USA, and an assumption of large development in transport and aviation which arenāt supported by actuality. Within the case of transport, 40% of bulks are coal, oil and fuel and people are going to decrease radically within the coming many years, so transport demand as an entire goes to plummet. Inland and quick sea transport is already electrifying, in order thatās not a requirement development space, as soon as once more exterior of the USA. Aviation development goes to be a lot slower than IATA and Boeing insist and way more of it’ll electrify as properly.
My projections require 180 million tons of biodiesel and biokerosene in 2100, 70 million for transport, and the world is already manufacturing 70 million tons of biodiesel at present per the IEA. However 500 million ton projections are rife, and other people holding onto that perception will rightly say we willāt simply manufacture that a lot biofuel.
My place is predicated on an evaluation of the entire pathways to biofuels, lots of them from present biomass waste streams we’re landfilling at present, together with the 33% of all meals, a full 2.5 billion tons, we landfill yearly world wide.
Over 40% assist for biofuels for transport isnāt dangerous, in different phrases. Itās aligned with actuality and itās the issue of getting everybody to agree what truly is a sustainable biofuel thatās inflicting shipowners to query how a lot theyāll get this decade.
Methanol taking pictures up this yr have to be making the Methanol Instituteās lobbying hearts develop two sizes, or not less than their year-end bonuses. Thatās largely attributable to a hangover, which is maybe applicable for an alcohol. Methanol is a tank-to-wake winner, way more so than LNG with itās slippage. However well-to-tank sucks, and methanolās present carbon depth is nearly thrice worse than HFO.
For the previous decade the methanol trade has been promoting tank-to-wake and promising that well-to-wake could be cleaned up sooner or later and be low-cost besides. Yeah, not so quick.
Sadly, they developed a head of steam. Corporations like one-time consumer Stena Sphere, which invited me to debate maritime decarbonization in Glasgow final yr, began engaged on burning methanol on ships sometimes as proof of idea a few decade in the past. Delivery large Maersk believed the hype about low-cost hydrogen and methanol being by-product of it, and so they put in orders for dual-fuel methanol ships and even closed some inexperienced methanol offers. These offers have been largely biomethanol, nevertheless, not hydrogen-derived methanol.
The mixture of laborious lobbying and Maersk led a couple of different transport corporations to place in orders for dual-fuel methanol ships. Thatās led to a ebook of ships and thatās led to a bunch of shipowners pondering that there have to be some there there if different shipowners are shopping for the sips.
As I preserve saying, the great factor about methanol twin gas ships is that theyāll nonetheless be capable to burn biodiesel, and additional, thatās what theyāll be burning over the approaching many years. The just about 40% assist is as a result of shipowners don’t know that getting agreed upon requirements for sustainable methanol can be simply as powerful as as for biodiesel.
However as I additionally mentioned to the Stena viewers final yr, if biologically sourced methanol turns into the low-carbon transport gas of selection, I receivedāt complain a lot. Iāll surprise why they selected a sub-optimal selection in comparison with batteries and biofuels, however I receivedāt lose sleep over it.
The autumn of HFO with carbon seize is an effective factor, however at nearly 40%, transport delusions that theyāll preserve the whole lot the identical and put an inexpensive vacuum cleaner on their smokestacks are clearly persisting. It is a mixture of psychology ā an inexpensive technical repair and nothing else is a really interesting story ā and heavy lobbying by the fossil gas trade. As I mentioned throughout my India utility professionals seminar the opposite week, Carbon Seize Is Largely An Oil & Fuel Business Shell Sport. That may proceed to sink in as foolish trials show actuality to but once more be actuality and startups within the house founder.
Sadly, the expertise with the International Centre for Maritime Decarbonizationās ammonia bunkering trial makes it clear that that groupās multi-million greenback efforts receivedāt present the nail within the coffin for both ammonia or carbon seize on ships, being solely dedicated to narrowly making the expertise work with none printed technoeconomics or, within the case of ammonia, any reasonable threat publications. Fortunately, they’re additionally engaged on biofuel provenance tracing, so some good will come of it.
The drop in hybrid energy trains ā fuels plus batteries or different faint hope power storage programs ā dropped. I believe a little bit of that’s that power storage programs that failed miserably to achieve traction towards batteries elsewhere have overhyped, oversold and failed, so thereās some jaundiced views. Itās laborious to say why that is the case in any other case, as battery costs have continued to plummet yearly, with costs of $137/kWh in 2020 dropping to $56 for LFP this yr.
And a Berkeley Nationwide Laboratory examine printed in Nature Vitality in 2022, Fast battery value declines speed up the prospects of all-electric interregional container transport, makes the robust case that at $100 per kWh, 1,500 km routes are break even for batteries. Itās not mass or quantity, itās value, is the examineās conclusion, and battery breakevens are right here even when the trade is molecule-centric.
Hybrid energy trains are a giant a part of my projection for maritime decarbonization, not less than for deep water transport. I count on all nationwide waters and port operations to be working on batteries, and an growing proportion of worldwide water motion. Batteries solely will win out for inland and most quick sea transport.
However thereās lobbying at work right here too. The amplification of the remarkably small variety of lithium ion battery fires and the disinformation campaigns attributing inner combustion fires to electrical autos has undoubtedly had an impression on shipowners as properly. The fossil gas trade realizes that they willāt even pivot to biofuels if batteries win, so they’re combating a propaganda marketing campaign on a number of fronts.
Nonetheless, a 3rd of the respondents nonetheless charge hybrid fashions as robust contenders for the following decade, so thereās that.
Then we get into a budget seats with restricted assist. That ammonia continues to be seeing 30% assist is thoughts boggling. Because the well-to-wake emissions present, for unabated ammonia emissions are 5.6 instances worse than HFO. Tank-to-wake is superior as a result of ammonia doesnāt have any carbon in any respect, however thatās irrelevant as a result of the stuff is an emissions bomb upstream. Thatās going to be laborious and ā most significantly ā costly to abate, so ammonia can be priced out of the market.
After which thereās the hazard to crews, port workers, the residents of cities round ports and marine life. Ammonia is nasty stuff, and whereas we do ship it globally as a result of itās a necessary fertilizer, we deal with it as a poisonous and dangerous substance and solely let specifically educated port and transport crews work with it in specifically segregated parts of ports.
Ammonia isnāt going to get cheaper or safer, in order that it may be made truly low carbon is irrelevant. That 30% of shipowners havenāt figured that out is fairly miserable. Maybe they’re those working the 66 or so ammonia tankers working across the place and know theyāll by no means need to be close to the ships or ports personally.
Then thereās nuclear. Hope springs everlasting, however as I mentioned final yr, No, There Gainedāt Be Nuclear-Powered Business Delivery This Time Both. The complete overhyped thought of nuclear business transport was tried within the Nineteen Fifties and nations truly introduced in legal guidelines prohibiting it. No business port has any security or operational tips at present for accepting a nuclear freight ship, and none are creating them. The owner-operator schism when it comes to capital prices vs working value advantages isnāt irresolvable, but it surelyās a Gordian knot.
The complete idea depends upon small modular reactors present as commercialized merchandise and scaled when it comes to floor deployment to make them low-cost sufficient for business ships. Thatās simply not going to occur in ten years, and even 40. As soon as once more, as I mentioned final yr, Shoveling Cash Into Small Modular Nuclear Reactors Gainedāt Make Their Electrical energy Low-cost. Far too many designs competing for much too little deployment for any of them to learn from the expertise curve.
That nuclear has doubled in hoped for assist as a viable different throughout the subsequent ten years can solely be ascribed to confusion about the whole lot else on the a part of shipowners. It is a case of throwing up their palms and praying for a miracle. No business freight ship powered by nuclear reactors exists, nobody is constructing any, no port is keen to simply accept them, the economics donāt stack up, and but 22% of shipowners suppose itās a this-decade a part of the answer? Clearly irrational pondering was setting in after they have been answering about nuclear.
Hydrogen assist plummeting from nearly 30% to below 20% can solely be thought-about a blessing because the scales of the hydrogen hype fall from maritime transport skilledās eyes. Everybody that severely works on value fashions quickly finds that it could be extremely costly in comparison with apparent options, however lots of horrible value fashions have been put ahead previously decade by in any other case severe organizations.
Whereas I referred to as out the ICCTās nice FUMES examine above, itās value remembering that they fell down on hydrogen. Again within the late 2010s, they determined for some motive of their very own that hydrogen was important to a number of completely different transportation modes, that it was too costly and so the one answer was to seek out methods to fake it was going to be actually low-cost. A few of their work had affordable kernels of knowledge and logic, however then they need off base from that fairly badly. They asserted that truck stops in Europe would get electrical energy loads cheaper to make hydrogen than to place in truck batteries, and got here to the unsupportable conclusion that hydrogen would solely value 10% extra per kilometer for power than electrical energy consequently. They pretended that hydrogen was important for aviation and could be low-cost.
And, after all, they pretended that cryogenic hydrogen with deeply unrealistic hydrogen manufacturing prices and no distribution or liquification prices could be out there for transport. To be clear, they have been removed from alone within the delusion of low-cost inexperienced hydrogen. Studies from in any other case credible organizations world wide have been pretending that electrical energy, electrolyzers, hydrogen storage and hydrogen distribution could be vastly cheaper than any reasonable, knowledgeable perspective would assist. On this, they have been mightily supported by the fossil gas trade once more, which might solely win if the world tries to make hydrogen an power service. Both actual decarbonization, nearly solely by direct electrification and plenty of renewables, could be deferred one other decade, or governments would throw a number of cash on the fossil gas trade for carbon seize for blue hydrogen.
However the previous couple of years of inexperienced hydrogen offers has put a stake by the vampiric perception in low-cost inexperienced hydrogen. Boston Consulting Group printed a depressing piece late final yr that discovered that the common deal was struck at a worth of ā¬9.45 per kilogram, and admitted that the āconsensusā ā learn shared delusion ā of ā¬3 per kg hydrogen in 2030 wasnāt reasonable, and that ā¬5 to ā¬8 was the vary organizations must be making ready for. The higher finish of that vary is de facto what they need to anticipating, and thatās only for manufacturing the stuff. At present unabated hydrogen is delivered by pipeline in Germany for ā¬6 to ā¬8, and there’s no means for inexperienced hydrogen to each be anyplace close to that worth delivered.
The transport trade seems to have been paying consideration. House ownersā perception that hydrogen could be part of decarbonization this decade dropped from 27% to 18%. Thatās simply extra proof that actuality is beginning to break by the hydrogen hype machine, even when the most effective outcome would having been to nip the latest iteration within the bud a decade in the past.
Windpower being up barely may be ascribed to lots of press for a few tiny freight vessels. That is the supply bias, the place having heard about one thing sufficient instances that it was vaguely acquainted, extra of them answered as if it may be an inexpensive different. Even the ICS doesnāt imagine that, calling it ānot a viable major propulsion technique for many business functionsā within the report. Within the tiny niches the place it may be used, it’ll avoid wasting gas. My cash continues to be on autolaunching and autofurling bow-mounted parafoils as the first answer that can be helpful on some routes. Amongst different issues, it receivedāt intervene with the cranes in container ports, in contrast to each different different.
Then thereās the true head scratcher, batteries. As famous above, battery costs have plummeted, LFP batteries donāt have even the statistically restricted thermal runaway problems with lithium ion batteries and thereās growing technoeconomic assist for battery transport. This yr noticed two 700 TEU electrical container ships begin plying 1,000 km routes on the Yangtze, in addition to a good quantity of realization that containerized batteries used for grid storage could possibly be winched on and off ships and charged in transshipment terminals.
Every little thing must be arising roses for batteries, however clearly there are irrational headwinds within the house. That mentioned, it’s a query of the following decade, and nobody is shopping for battery solely ships for crossing the Atlantic but. Itās absurd that shipowners at the moment suppose sails have extra potential than batteries, however thatās the place we’re.
Then thereās liquid petroleum fuel (LPG), LNGās uglier, much less lobbied for sibling. Assist for it’s fairly moderately sinking.
As famous, thereās lots of confusion within the trade about whatās going to be powering their ships over coming decade. Lobbying by the fossil gas trade has created lots of that. A robust cognitive bias for molecules for power is undoubtedly taking part in a component. Resistance to vary is a part of it. The failure of long-promoted options that turned out to to not be low-cost, simple and even options has created fatigue. The problem of really agreeing on issues hasnāt helped. The Worldwide Maritime Group solely requiring well-to-wake lifecycle carbon assessments beginning in 2021 didnāt assist. A few of it, after all, is members of the maritime trade who rely on continued confusion to stop any requirement for change who’re creating pointless battle to that finish as a tactic.
Nevertheless it receivedāt actually matter in the long term. What can be most cost-effective and best is batteries and biofuels, usually in mixtures. The lobbyists canāt change the fundamentals of economics and science, and so they can solely make wise individuals fake in any other case for thus lengthy. This confusion will go.
