For 3 years, the Worldwide Chamber of Transport has been operating a survey of ship house owners, protecting a number of domains, together with greatest dangers to transport, adjustments in transport patterns with initiatives like friendshoring and most relevantly for this dialogue, decarbonization. Just lately they dropped their 2023-2024 survey, and the outcomes point out ongoing confusion amongst shipowners, in addition to loads of profitable lobbying and a few wishful considering.

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, it’s taken the passenger ferry and cruise ship industries by storm, principally as a result of it doesn’t 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 emissions  in comparison with heavy gas oil, one thing that the shipowners acknowledge. Nonetheless, even that’s an overstatement, as that’s in a greater than greatest case situation.

Effectively-to-tank is problematic, as the worldwide pure gasoline and LNG provide chain is leaky as a sieve, particularly in main exporting nations just like the US, Russia and Qatar. Whereas pure gasoline 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 a long time. In consequence, upstream methane emissions are fairly excessive, whereas advocates have a tendency to advertise northern European ranges of emissions. Methane emissions, in fact, are extremely problematic on account of methane’s excessive international warming potential.

Liquifying pure gasoline requires 8% to 12% of the embodied vitality, so upstream fugitive emissions are elevated by these percentages. And most liquification services burn pure gasoline to create the electrical energy for liquification, so extra properly to tank emissions. Then there’s boil off. Higher operators reliquify extra boil off, however meaning burning extra LNG to energy liquification.

And tank-to-wake isn’t 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 business normal methane detection expertise on smokestacks on the vessels within the research. Whereas the business was selling solely 3.5% methane slippage — the proportion of the gas that was unburnt — the ICCT’s research discovered a mean of 6.4%.

LNG is extra vitality 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 vitality of LNG solely emits 2.3 tons, which looks like a win. However 6.4% slippage provides 1.6 tons of carbon dioxide equal (CO2e) to LNG’s emissions, bringing it as much as 3.7 tons, properly above HFO. That’s not a local weather win.

The business has been swayed by lifecycle carbon evaluation’s like Sphera’s, which discovered 23% financial savings well-to-wake, however that’s not remotely sensible. What’s the provenance of that research? It was commissioned by two organizations, SEA-LNG and SGMF (Society for Gasoline as a Marine Gas) which clearly discovered a prepared consultancy to jot down a report that gave them the outcomes they wanted to advertise their product.

Even the business normal 3.5% slippage provides 0.8 tons of CO2e, which means that the ‘good’ case is precisely the identical because the HFO base case. That’s earlier than you add well-to-tank emissions. This isn’t a local weather win, it’s a distraction by the fossil gas business, 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’ll be able to see why it’s taken off and why regardless of precisely zero local weather profit it stays probably the most extremely rated various vitality supply for transport for the subsequent decade, no less than among the many 104 shipowners who responded in full to the survey.

Biofuels, an precise local weather resolution, have been slipping too. Not like LNG, the place the advantages are vaporware, the slippage is probably going on account of ongoing worldwide confusion about what constitutes sustainably manufactured biodiesel. In knowledgeable dialogue this morning, we have been shaking our heads over the EU’s legislated distaste for cropped biofuels like soy beans or canola whereas concurrently contemplating chopping down virgin timber to pelletize for thermal vitality and electrical energy to be carbon impartial.

Jurisdictions within the USA like California are following down this foolish pathway as properly, based mostly on a mixture of things. The primary is the idea that massively extra biofuels than are at present manufactured can be required, which isn’t the case, however is quite common. That’s based mostly on an assumption of a continuation of floor transportation requiring fuels when globally it’s all going to affect, with slower geographies just like the USA, and an assumption of large progress in transport and aviation which aren’t supported by actuality. Within the case of transport, 40% of bulks are coal, oil and gasoline and people are going to decrease radically within the coming a long time, so transport demand as a complete goes to plummet. Inland and brief sea transport is already electrifying, in order that’s not a requirement progress space, as soon as once more exterior of the USA. Aviation progress goes to be a lot slower than IATA and Boeing insist and far more of it can 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 right this moment per the IEA. However 500 million ton projections are rife, and folks holding onto that perception will rightly say we are able to’t simply manufacture that a lot biofuel.

My place relies on an evaluation of the entire pathways to biofuels, lots of them from present biomass waste streams we’re landfilling right this moment, together with the 33% of all meals, a full 2.5 billion tons, we landfill yearly around the globe.

Over 40% assist for biofuels for transport isn’t unhealthy, in different phrases. It’s aligned with actuality and it’s the issue of getting everybody to agree what truly is a sustainable biofuel that’s inflicting shipowners to query how a lot they’ll get this decade.

Methanol capturing up this yr have to be making the Methanol Institute’s lobbying hearts develop two sizes, or no less than their year-end bonuses. That’s principally on account of a hangover, which is maybe acceptable for an alcohol. Methanol is a tank-to-wake winner, far more so than LNG with it’s slippage. However well-to-tank sucks, and methanol’s present carbon depth is nearly thrice worse than HFO.

For the previous decade the methanol business has been promoting tank-to-wake and promising that well-to-wake can 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 often as proof of idea a few decade in the past. Transport large Maersk believed the hype about low cost hydrogen and methanol being spinoff of it, and so they put in orders for dual-fuel methanol ships and even closed some inexperienced methanol offers. These offers have been principally biomethanol, nevertheless, not hydrogen-derived methanol.

The mixture of laborious lobbying and Maersk led a number of different transport companies to place in orders for dual-fuel methanol ships. That’s led to a guide of ships and that’s led to a bunch of shipowners considering that there have to be some there there if different shipowners are shopping for the sips.

As I preserve saying, the good factor about methanol twin gas ships is that they’ll nonetheless be capable to burn biodiesel, and additional, that’s what they’ll be burning over the approaching a long time. 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 stated to the Stena viewers final yr, if biologically sourced methanol turns into the low-carbon transport gas of selection, I received’t complain a lot. I’ll marvel why they selected a sub-optimal selection in comparison with batteries and biofuels, however I received’t lose sleep over it.

The autumn of HFO with carbon seize is an effective factor, however at nearly 40%, transport delusions that they’ll preserve all the pieces the identical and put an affordable vacuum cleaner on their smokestacks are clearly persisting. This can be a mixture of psychology — an affordable technical repair and nothing else is a really interesting story — and heavy lobbying by the fossil gas business. As I stated throughout my India utility professionals seminar the opposite week, Carbon Seize Is Principally An Oil & Gasoline Trade Shell Recreation. 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 World Centre for Maritime Decarbonization’s ammonia bunkering trial makes it clear that that group’s multi-million greenback efforts received’t 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 revealed technoeconomics or, within the case of ammonia, any sensible threat publications. Fortunately, they’re additionally engaged on biofuel provenance tracing, so some good will come of it.

The assist for hybrid energy trains — fuels plus batteries or different faint hope vitality storage programs — dropped. I think a little bit of that’s that vitality storage programs that failed miserably to achieve traction towards batteries elsewhere have overhyped, oversold and failed, so there’s some jaundiced views. It’s 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 research revealed in Nature Vitality in 2022, Speedy battery price declines speed up the prospects of all-electric interregional container transport, makes the sturdy case that at $100 per kWh, 1,500 km routes are break even for batteries. It’s not mass or quantity, it’s price, is the research’s conclusion, and battery breakevens are right here even when the business is molecule-centric.

Hybrid energy trains are a giant a part of my projection for maritime decarbonization, no less than for deep water transport. I anticipate all nationwide waters and port operations to be operating on batteries, and an rising proportion of worldwide water motion. Batteries solely will win out for inland and most brief sea transport.

However there’s lobbying at work right here too. The amplification of the remarkably small variety of lithium ion battery fires and the disinformation campaigns attributing inside combustion fires to electrical autos has undoubtedly had an affect on shipowners as properly. The fossil gas business realizes that they will’t 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 sturdy contenders for the subsequent decade, so there’s that.

Then we get into a budget seats with restricted assist. That ammonia remains to be seeing 30% assist is thoughts boggling. Because the well-to-wake emissions present, for unabated ammonia emissions are 5.6 occasions worse than HFO. Tank-to-wake is superior as a result of ammonia doesn’t have any carbon in any respect, however that’s irrelevant as a result of the stuff is an emissions bomb upstream. That’s going to be laborious and — most significantly — costly to abate, so ammonia can be priced out of the market.

After which there’s 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 it’s an important fertilizer, we deal with it as a poisonous and unsafe substance and solely let specifically educated port and transport crews work with it in specifically segregated parts of ports.

Ammonia isn’t going to get cheaper or safer, in order that it may be made truly low carbon is irrelevant. That 30% of shipowners haven’t figured that out is fairly miserable. Maybe they’re those working the 66 or so ammonia tankers operating across the place and know they’ll by no means must be close to the ships or ports personally.

Then there’s nuclear. Hope springs everlasting, however as I stated final yr, No, There Received’t Be Nuclear-Powered Industrial Transport This Time Both. Your complete overhyped concept of nuclear business transport was tried within the Fifties and nations truly introduced in legal guidelines prohibiting it. No business port has any security or operational tips right this moment for accepting a nuclear freight ship, and none are creating them. The owner-operator schism by way of capital prices vs working price advantages isn’t irresolvable, however it’s a Gordian knot.

Your complete idea is dependent upon small modular reactors present as commercialized merchandise and scaled by way of floor deployment to make them low cost sufficient for business ships. That’s simply not going to occur in ten years, and even 40. As soon as once more, as I stated final yr, Shoveling Cash Into Small Modular Nuclear Reactors Received’t 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 various throughout the subsequent ten years can solely be ascribed to confusion about all the pieces else on the a part of shipowners. This can be a case of throwing up their fingers and praying for a miracle. No business freight ship powered by nuclear reactors exists, nobody is constructing any, no port is prepared to simply accept them, the economics don’t stack up, and but 22% of shipowners assume it’s a this-decade a part of the answer? Clearly irrational considering was setting in after they have been answering about nuclear.

Hydrogen assist plummeting from nearly 30% to beneath 20% can solely be thought of a blessing because the scales of the hydrogen hype fall from maritime transport professionals’ eyes. Everybody that critically works on price fashions quickly finds that it might be extremely costly in comparison with apparent options, however loads of horrible price fashions have been put ahead prior to now decade by in any other case critical organizations.

Whereas I referred to as out the ICCT’s nice FUMES research above, it’s price remembering that they fell down on hydrogen. Again within the late 2010s, they determined for some cause of their very own that hydrogen was important to plenty of completely different transportation modes, that it was too costly and so the one resolution was to seek out methods to faux it was going to be actually low cost. A few of their work had cheap kernels of knowledge and logic, however then they went off base from that fairly badly. They asserted that truck stops in Europe would get electrical energy quite a bit cheaper to make hydrogen than to place in truck batteries, and got here to the unsupportable conclusion that hydrogen would solely price 10% extra per kilometer for vitality than electrical energy in consequence. They pretended that hydrogen was important for aviation and can be low cost.

And, in fact, they pretended that cryogenic hydrogen with deeply unrealistic hydrogen manufacturing prices and no distribution or liquification prices can be obtainable for transport. To be clear, they have been removed from alone within the delusion of low cost inexperienced hydrogen. Reviews from in any other case credible organizations around the globe have been pretending that electrical energy, electrolyzers, hydrogen storage and hydrogen distribution can be vastly cheaper than any sensible, knowledgeable perspective would assist. On this, they have been mightily supported by the fossil gas business once more, which might solely win if the world tries to make hydrogen an vitality service. Both actual decarbonization, nearly totally via direct electrification and plenty of renewables, can be deferred one other decade, or governments would throw plenty of cash on the fossil gas business for carbon seize for blue hydrogen.

However the previous couple of years of inexperienced hydrogen offers has put a stake via the vampiric perception in low cost inexperienced hydrogen. Boston Consulting Group revealed a dismal piece late final yr that discovered that the typical deal was struck at a value of €9.45 per kilogram, and admitted that the ‘consensus’ — learn shared delusion — of €3 per kg hydrogen in 2030 wasn’t sensible, and that €5 to €8 was the vary organizations ought to be making ready for. The higher finish of that vary is absolutely what they need to anticipating, and that’s only for manufacturing the stuff. At the moment unabated hydrogen is delivered by pipeline in Germany for €6 to €8, and there’s no means for inexperienced hydrogen to ever be wherever close to that value delivered.

The transport business seems to have been paying consideration. House owners’ perception that hydrogen can be part of decarbonization this decade dropped from 27% to 18%. That’s simply extra proof that actuality is beginning to break via the hydrogen hype machine, even when the most effective consequence would having been to nip the latest iteration within the bud a decade in the past.

Windpower being up barely may be ascribed to loads of press for a few tiny freight vessels. That is the supply bias, the place having heard about one thing sufficient occasions that it was vaguely acquainted, extra of them answered as if it could be an affordable various. Even the ICS doesn’t imagine that, calling it “not a viable primary propulsion method for most commercial applications” within the report. Within the tiny niches the place it may be used, it can avoid wasting gas. My cash remains to be on autolaunching and autofurling bow-mounted parafoils as the first resolution that can be helpful on some routes. Amongst different issues, it received’t intervene with the cranes in container ports, in contrast to each different various.

Then there’s the true head scratcher, batteries. As famous above, battery costs have plummeted, LFP batteries don’t have even the statistically restricted thermal runaway problems with lithium ion batteries and there’s rising 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 may very well be winched on and off ships and charged in transshipment terminals.

Every little thing ought to be developing roses for batteries, however clearly there are irrational headwinds within the house. That stated, it’s a query of the subsequent decade, and nobody is shopping for battery solely ships for crossing the Atlantic but. It’s absurd that shipowners at present assume sails have extra potential than batteries, however that’s the place we’re.

Then there’s liquid petroleum gasoline (LPG), LNG’s uglier, much less lobbied for sibling. Assist for it’s fairly moderately sinking.

As famous, there’s loads of confusion within the business about what’s going to be powering their ships over coming decade. Lobbying by the fossil gas business has created loads of that. A powerful cognitive bias for molecules for vitality is undoubtedly taking part in a component. Resistance to alter 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 truly agreeing on issues hasn’t helped. The Worldwide Maritime Group solely requiring well-to-wake lifecycle carbon assessments beginning in 2021 didn’t assist. A few of it, in fact, is members of the maritime business who rely upon continued confusion to stop any requirement for change who’re creating pointless battle to that finish as a tactic.

However it received’t actually matter in the long term. What can be least expensive and simplest is batteries and biofuels, typically in combos. The lobbyists can’t change the fundamentals of economics and science, and so they can solely make smart individuals faux in any other case for therefore lengthy. This confusion will cross.
