The Remarkable Progress of Renewable Energy

BP makes billion-dollar offshore wind play - Axios
Driving the news: BP is paying Equinor $1.1 billion for a 50% stake in wind farms Equinor is developing off the coasts of New York and Massachusetts. The oil-and-gas companies — which are both making more moves into renewables — also announced a "strategic partnership" to jointly pursue other U.S. offshore projects.

Why it matters: It's a sign of BP's pledge to speed up its diversification into low-carbon technologies and shrink its fossil fuel business — which currently dominates its portfolio — over the long term.
Seems like these oil companies are using their expertise in offshore construction. Good that there is a path out of fossil fuels for them.

European Trio Working On Solar Canopy For Highways
The solar power infrastructure would need to be developed to handle things a bit differently from rooftop solar panels or even solar panel carports. For one, you wouldn’t want tens of thousands of dollars (or euros) of damage every time there’s an accident. So, the system would need to be developed in a way that it would be especially sturdy or resilient in the case of impact. It would also need special design to manage wind low as well as rain and snow in a way that is compatible with the needs of the roadway network. Naturally, traffic safety is another unique concern, and efficient maintenance would be important to making it cost competitive.

What’s the point? Well, there are also some inherent benefits to such a system. “In addition to the double use of space, the scientists expect other positive outcomes, including the protection of road surfaces from precipitation and overheating,” Sandra Enkhardt writes for PV Magazine. Such a system can also help reduce noise pollution.
I like that. It's a great way of using land area, because it doesn't interfere with other uses.
 
Renewables Rescue Stability as the Grid Loses Spin | News | NREL - "Across the world, renewable power is displacing traditional generation, but can renewables also replace the critical stability functions that go with it? NREL studies are confirming in the field and on live power systems that solar, wind, and hybrid power plants can provide their own source of grid stability—potentially unlike anything currently on the grid."

So that seems to settle that conundrum. Putting lots of storage online will help even more, because it can easily include very fast-reacting storage like supercapacitors.

Rooftop Solar And Energy Storage Units Could Help During Emergency Blackouts | KPBS - "He said San Diego has among the highest number of rooftop solar installations in the U.S., due to high electricity costs and plenty of sunshine. Airth said San Diego has over 100,000 solar installations but only about 7,000 battery units installed."

Home battery sets are still rather expensive, like $8,000 - $14,000. (numbers from the article)

Transparent solar panels for windows hit record 8% efficiency | University of Michigan News - "The team achieved 8.1% efficiency and 43.3% transparency with an organic, or carbon-based, design rather than conventional silicon. While the cells have a slight green tint, they are much more like the gray of sunglasses and automobile windows."

Good that windows can be put to work in this way.
 
'Farewell, fossil fuels'? What oil's demise will do to the world's leading economies | TheHill
But now there is an explosive new ingredient to start taking into account. On Monday, the oil world woke to the news that London-based energy giant BP is predicting that world oil demand could peak by the early 2020s. Previously, the accepted wisdom was that oil would remain the predominant fuel — over natural gas, coal, nuclear and renewables — well into the 2030s. “Green” consumer preferences forcing different political choices has been added to by the economic shift caused by the coronavirus. It is not quite time to say “Farewell, fossil fuels,” but it is the first draft of their obituary.

... Yergin points out that oil giants such as Russia and Saudi Arabia will find themselves in deep economic trouble unless they transform their economies quickly. Their particular problem is that they can’t transform them quickly enough — not even Saudi Arabia, despite the ambitions of its de facto leader, Crown Prince Mohammad bin Salman, and his “Vision 2030” plans.

The main beneficiary of the trend away from oil will be China, currently a significant importer.
It'll be great to see Saudi Arabia's royal family cut down to size. They all should have to work for their living. Vladimir Putin also deserves to be taken down a notch.

Power-to-hydrogen for multi-energy systems – pv magazine International - "Scientists in Switzerland say power-to-hydrogen is particularly promising for coupling electricity and heating and offsetting seasonal variation in renewables generation in sector-coupled energy networks. Their analysis indicated the technology may be especially useful in areas with a high ratio of seasonal thermal-to-electric demand."

It will require a lot of hydrogen storage, and that will be rather difficult - like natural-gas storage, but worse. Methane's boiling point is 112 K, while hydrogen's is 20 K.
 
But hydrogen can be handled with much of the infrastructure already built for natural gas, like pipelines.

Why behind-the-meter will define Australia’s next solar boom | EcoGeneration - "Power behind-the-meter, defined as producing and consuming energy on-site, is quickly eclipsing all other models of electricity use and catapulting solar into unbeatable economic viability.

The countries painting their pandemic recoveries green - Axios
Green investments account for roughly 1% of the overall $12 trillion currently pledged by major economies recovering from pandemic-induced recessions, a BloombergNEF report finds.

GE to stop producing coal-fired power plants | TheHill
Despite efforts from the Trump administration to bolster the coal industry, market forces have pushed utilities to cheaper, cleaner forms of electricity, with many utilities opting to retire coal-fired power plants early.

Last year coal production fell to the lowest level since 1978, according to data released by the U.S. Energy Information Administration.

Coal production in 2019 was just 7 percent lower overall than production in 2018, part of a larger trend of coal production easing since production peaked in 2008. Production is expected to decline again this year.
Is coal in terminal decline? That would be welcome.
 
In Utah, hydrogen and salt domes are winning the west for renewable energy | Spectra
There was a big buzz about a "hydrogen economy" during George Bush II's presidency.
"There was a lot of buzz, but clearly that fizzled out," Ducker says. "Fifteen years later, the dynamics are fundamentally different. Just in the past year, there's been overwhelming interest in storing renewable power, particularly in the western United States where curtailment of renewable power generation is now a routine occurrence."
Curtailment? Seems like it has come a long way.
The three biggest challenges in using hydrogen to store clean energy are converting renewable electricity to hydrogen affordably, storing large amounts of hydrogen for long periods of time at low cost, and converting the hydrogen back to electricity at low cost and high efficiency.

...
Ducker knew that his colleagues at Mitsubishi Power had a development program to use hydrogen as a fuel in their largest and most efficient gas turbine. He also knew that the electrolysis products to convert electricity to hydrogen existed and could be cost reduced through improved economies of scale.

Hydrogen storage at substantial and affordable scale however, had been a real barrier.

Enter the salt dome beneath Delta, Utah. Salt domes are underground salt formations, huge saline globes that intrude into other strata of the earth. Given salt's impermeability, they can be hollowed out and used as underground storage for liquid and gas fuels.
A combustion turbine instead of fuel cells? While one's doing that, one could have hydrogen-powered combined-cycle generation, but steam systems don't have very great reaction time.

Salt domes can be hollowed out by pumping water into them to dissolve the salt in that water. The resulting brine is then pumped out.
The resulting caverns are cylindrical and typically between 150 and 300 feet in diameter and 1,000 and 1,500 feet deep. A single cavern can contain enough pressurized hydrogen to produce 150,000 megawatt-hours of energy. You would need 40,000 shipping containers of lithium-ion batteries for the same megawatt-hours.
Interesting alternative to above-ground storage tanks.

Poland’s Plan To Phase Out Coal Mines, Opens The Door For Solar Energy Projects
Poland, one of the world’s biggest producers and users of coal, has made a bold move to phase out fossil fuels and develop more renewables, especially solar energy.
Go from 2.5 GW to 16 GW of PV-cell electricity generation, go from 80% to 10% coal.
However, one of the region’s most prominent photovoltaic developers said he thinks Poland will switch to renewables even faster than the government projects. Deividas Varabauskas, chief executive officer of Sun Investment Group in nearby Vilnius, Lithuania, said Poland’s solar energy markets can soar as the country gradually exits from dependence on coal.

“Big Polish utilities are becoming likely buyers [of solar panels] now,” he told Bloomberg. “We could become partners. They are the established players in the old energy world and we’re kind of the guys from the future.”
 
How Coal-Loving Australia Became the Leader in Rooftop Solar - The New York Times
CAIRNS, Australia — Australia is the world’s second-largest exporter of coal, which plays an outsize role in its economy and politics. But the country has also quietly become a renewable energy powerhouse.

About one in four Australian homes have rooftop solar panels, a larger share than in any other major economy, and the rate of installations far outpaces the global average. The country is well ahead of Germany, Japan and California, which are widely considered leaders in clean energy. In California, which leads U.S. states in the use of solar power, less than 10 percent of utility customers have rooftop solar panels.
The main reason that many Australians get these panels is because their electricity is often cheaper than electricity from the grid.

Though Australia's national government champions coal, many Australian states are firm supporters of solar panels and, more recently, batteries.

Rooftop solar panels now produce 5% of the nation's energy, as opposed to the US's 1%. With 25% of homes having solar panels, and assuming energy self-sufficiency, this means that homes consume about 1/5 of Australia's electricity. If solar panels supply only 1/2 of these homes' energy, then that means that homes consume about 2/5 of Australia's electricity.

The champion coal exporter: Indonesia.
Another reason Australia has rapidly expanded rooftop solar is that its states have sought to streamline building codes and make it easier to obtain permits. In the United States, municipalities tend to control codes and permitting, and many have not eased the way for rooftop solar, making installations more expensive and time consuming.

“What can California do to get to 30 percent penetration?” said Bernadette Del Chiaro, executive director of the California Solar and Storage Association. “Cut the red tape.”

China's biggest ever solar power plant goes live
Chinese President Xi Jinping last week committed his country to carbon neutrality by 2060. This week, China took a small-but-tangible step in achieving this goal as the country's biggest ever solar power station was connected to the grid in the northwest province of Qinghai.

The solar park has a capacity of 2.2GW. That makes it the second biggest in the world, narrowly trailing India's 2.245GW Bhadla solar park. Until now, China's biggest solar station was the Tengger Desert Solar Park, with a capacity of 1.54GW. For comparison, the US' biggest solar farm has a capacity of 579MW.

The power station also includes a storage component, as it includes a 202.86 MWh energy storage plant. Construction on the project was completed in September after just four months.
Four months!

Try building a nuclear reactor in four years. With that kind of performance from renewable energy, I seriously doubt that nuclear energy has much of a future, whether nuclear fission or nuclear fusion.

Wind and solar supply more than 50 pct of Australia’s main grid for first time – RenewEconomy
The share of renewable energy broke new records for the third consecutive day on Saturday, with wind and solar providing more than 50 per cent of the demand on Australia’s main grid for the first time, and for extended periods.

The strong wind and fine solar conditions across much of the eastern states – along with relatively low demand due to mild weather and the start of the holiday weekend in some states – has contributed to the record breaking streak.

A factory in Indiana is turning plastic waste into eco-friendly fuel - Business Insider
  • Waste solutions company Brightmark is converting plastic waste into fuel at its plant in Indiana.
  • The company is aiming to process 100,000 tons of plastic next year, its first year of full-time operation.
  • Studies show that by 2050, there will be more plastic waste in the ocean than fish — a trend Brightmark hopes to reverse.

...
The full conversion process is a company secret, but it begins with breaking bales of plastic apart, then shredding the plastic into small pellets.

"We've got employees that are basically refinery operators," plant manager Jason Sasse added. "So they take the plastic pellet and they convert that into our finished products."

Finished products include ultra-low sulfur diesel fuel, and companies like BP are already placing orders.
Seems like they bake it to decompose it and make hydrocarbons. Just like how petroleum itself was formed.

I recall posting on similar systems earlier. I find this very welcome, because it makes it easier to continue using plastics. Single-use plastics may be problematic in some ways, but in some cases, they are good for sanitation and preservation. Wrapping food in plastic can keep it from getting spoiled or contaminated or dried out.
 
Solar-powered steel production from Lightsource bp’s Bighorn Project in Colorado – pv magazine USA
A crucial and historical steel mill in Pueblo, Colorado will be the first in North America to rely on solar power, according to Skip Herald, the CEO of steel and mining company, Evraz North America.

...
Kevin Smith, CEO of the Americas for Lightsource, said, “The more than 700,000 solar panels can provide 90% of the plant’s energy needs at peak production” and 95% of the mill’s annual energy demand, according to other reports.

The plant will turns recycled scrap metal into “clean steel, including the most sustainable rail in the world,” according to Herald. Ervaz is a Russian-owned steel and mining conglomerate.
Presumably doing electric heating -  Electric arc furnace -  Induction furnace - iron has a melting point of 1500 C.
The iron and steel sector is the “world’s largest industrial source of climate pollution,” according to the Cold Steel Hot Planet report, which notes that steel represented approximately 5% of final energy use and 7% of emissions worldwide in 2013. In steel-making regions, many steel plants are often the largest or one of the largest electricity customers — the exact case for the Pueblo, Colorado plant.

Utility-scale solar developers like Lightsource bp are being kept busy with the proliferation of 100 MW-plus solar projects now in development. These large solar projects are no longer driven by RPS edicts but by corporate buyers and the sheer competitive pricing of solar or solar-plus-storage compared to other generation sources
Yet more evidence that renewable energy is becoming economically competitive.

Beijing Is Winning the Race to Build—and Sell—Clean Energy Technology
At the end of September, Chinese President Xi Jinping announced his country’s intention to peak its emissions by 2030 and be carbon neutral before 2060. To meet this goal, China will have to expand its domestic market for clean energy technologies, many of which it produces. China is also hoping to spur other countries to be more aggressive in lowering emissions—calling for a “Green Revolution”—and these countries could also be a market for Chinese technologies.

Thanks to initiatives like these, China is for now winning the global race to invent and manufacture the technologies that will allow a new low-carbon world. Europe, which has made its own commitment to become climate neutral by 2050, is not far behind.
So great to see.

It offers a wide range of energy solutions from small solar lanterns for lighting and mobile charging, to pico solar home systems with appliances like TVs and fans, all the way up to kW sized systems designed for residential, commercial, and industrial users.
How nice to see - solar energy succeeding in the poorer areas of the world.
 
Rocky Mountain Institute Study Shows Renewables Are Kicking Natural Gas To The Curb
After analyzing the most recent data from two of America’s largest electricity markets — ERCOT in Texas and PJM in the Northeast — the Rocky Mountain Institute has come to a startling conclusion. Renewables are muscling in on natural gas as the preferred choice for new electricity generation. In fact, according to RMI, what happened to coal is now happening to gas. What is needed, the organization argues, is a move away from the monopoly markets that have been the norm in the utility industry for more than 100 years and toward more open competition. Because when renewables compete head to head with thermal generation, they win hands down 95% of the time.

...
RMI finds that since 2018, the queue for clean energy projects has more than doubled while the queue for gas projects has been cut in half. In all, more than $30 billion worth of gas projects have been canceled or abandoned. Currently, the capacity of wind, solar, and storage projects slated for construction in ERCOT and PJM is ten times greater than for new gas projects.
That's so great to see -- now competing with natural gas. It is mostly methane, CH4, and it's as good as it gets for fossil fuel for CO2 emission per unit of usable energy. But CH4 has a downside. Like CO2, it is also a greenhouse gas, and it often leaks out from its distribution plumbing.
Federal policy is strongly influenced by who is sitting in the Oval Office and the choices that person makes when appointing people to government agencies like the Federal Energy Regulatory Commission. For instance, in 2018 the Orange Judas who occupies that office at present nominated Bernard McNamee — an avowed fossil fuel advocate who slobbers all over himself when Charles Koch waves dollars under his nose. McNamee is one of those phony free market conservatives who believes fervently in doing whatever he is told to believe by those paying him.
 
The oil lobby is lying. Canadian oil isn’t clean oil - Environmental Defence
The oil and gas industry is putting great efforts into trying to convince the Canadian public that they are making strides to be more environmentally responsible. Don’t buy it.

The fact is oil and gas companies’ total impact on Canada’s water, land, species, and the climate continues to grow. Even on a per barrel basis, oil companies are creating ever more carbon emissions.

Over the last three decades, Canada’s oil and gas sector has shifted towards production that is higher in carbon and more risky—from conventional oil to tar sands oil, and with increased production from offshore. This is documented in our new report on the barriers the oil and gas lobby puts up to slow progress on climate action. On average, the amount of carbon emitted to produce a barrel of Canadian oil has continuously increased since 1990—a 16 per cent increase overall. Canadian oil has never been dirtier.
A big part of the problem is that one has to get the oil out of the oil sands. That means baking it, and that takes energy. But is it worth it? The number is EROEI or EROI -- energy recovered over energy invested.

(PDF) Energy Return on Investment of Canadian Oil Sands Extraction from 2009 to 2015 - "Results of this paper show that EROI of both mining oil sands (range of value: 3.9–8) and in situ oil sands (range of value: 3.2–5.4) display an upward trend over the past 7 years; EROI of mining oil sands is generally higher, but is more fluctuating than the EROI of in situ oil sands. Compared with EROI of other hydrocarbons, the EROI of oil sands is still quite low, despite the fact that it is increasing gradually."

Very low, though they seem to be getting better at doing it, likely because they have a direct economic incentive to do so.

"In situ" = "in place"

Oil Sands Mining Uses Up Almost as Much Energy as It Produces | InsideClimate News - "Thanks to high global oil prices, industry can afford the large amount of energy needed to extract the oil and turn it into a usable fuel."
The average "energy returned on investment," or EROI, for conventional oil is roughly 25:1. In other words, 25 units of oil-based energy are obtained for every one unit of other energy that is invested to extract it.

But tar sands oil is in a category all its own.
Tar sands or oil sands? This geological feature used to be called tar sands, but the proponents of tar-sands oil have renamed this geological feature oil sands. But in any case, it is very heavy oil, and it needs to be cracked to make gasoline and diesel fuel.
Tar sands retrieved by surface mining has an EROI of only about 5:1, according to research released Tuesday. Tar sands retrieved from deeper beneath the earth, through steam injection, fares even worse, with a maximum average ratio of just 2.9 to 1. That means one unit of natural gas is needed to create less than three units of oil-based energy.

"They have to use a lot of natural gas to upgrade this heavy, sticky, gooky almost tar-like stuff to make it fluid enough to use," said Charles Hall, a professor at the State University of New York's College of Environmental Science and Forestry. Hydrogen from gas heats the tar sands so the viscous form of petroleum it contains, known as bitumen, can be liquefied and pumped out of the ground. In this way, Hall said, gas helps turn tar sands "into something a bit closer to what we call oil."
As we use up the easier oil, we move on to the more difficult oil, oil far offshore and oil in difficult-to-extract form.
 
Skepticblog » peak oil - "News from the oil patch" by Donald Prothero, May 02 2012

After describing the opulence of a petroleum-geologist conference when compared to an academic-geologist one, he gets down to business.
But the biggest take-home message is something oil geologists have known for years: oil is never going to be as cheap or easy to obtain again, and the global price of oil will get higher and higher as it becomes more and more scarce, especially with the huge increase in demand from developing countries like China and India. I heard this message over and over again, from the gossip on the exhibit hall floor with friends, to the plenary addresses by the top people in the oil business.
(link to the April 9, 2012 Time magazine cover story)
This fact has been known for some time, and was first predicted by the pioneering oil geologist M. King Hubbert in 1953. Using his knowledge of the history of non-renewable resources (which show a “bell curve” history of production, from their initial log growth phase to an equally rapid decline as the easily obtained resources vanish), plus his deep understanding of the amount and nature of oil reserves. he predicted that U.S. oil production would reach a peak in the early 1970s—and his prediction came true in 1971. Since then, U.S. oil production has steadily declined as fewer and fewer large fields were found, and older fields have been used up.

...
As the Time magazine article pointed out, now they’re spending most of their time and money on increasingly risky and expensive operations like fracking, pumping water in old fields to push out the last drops of oil, or mining oil sands with all their environmental costs. The biggest push is in offshore oil platforms—and the 2010 Gulf oil disaster (along with previous oil disasters on platforms around the world) shows just how risky it is to drill so far offshore.

...
To summarize: the era of cheap, easily obtained, abundant oil is over, and oil will soon become scarce despite more and more costly efforts to squeeze out every last drop from more and more “unconventional” sources. The fact that Hubbert’s model exactly predicted the U.S. oil peak, and seems to be predicting the global peak, should be strong enough evidence in and of itself. There is also the fact that the peak of discovery of major oil fields occurred 47 years ago, and there have been no giant oil fields found in a long time, and most of the world’s older oil fields are nearing their ends. There are no polls that show just how many qualified experts (geologists and geological engineers within and close to the oil industry) accept the concept of peak oil and the end of cheap abundant oil, but a lot of oil experts are on the record as supporting it, including a number of oil geologists and executives. My many friends in the oil business almost all tell me that “peak oil” is widely accepted among their colleagues, and they have long been forced to work with extraordinarily difficult exploration problems because there are no easy oil fields any more.
DP mentioned renewable energy toward the end:
Paul Roberts, in his excellent book The End of Oil, pointed out a model for other countries: Germany. Before 1990, German politics were controlled by big industry (especially coal companies) and coal miners’ unions. But the 1986 Chernobyl nuclear accident in the Ukraine galvanized the environmental awareness of the entire world, and by the 1990s, wind farms and other energy alternatives were rapidly emerging in Germany, spurred on by a law passed in 1990 to invest in carbon-free energy production.
He may not have anticipated how big it is now.

Spain Sets a $10.5 Billion Goal for Green Hydrogen
Spain is stepping up its efforts to enter the race to build a hydrogen industry, putting it on par with France and Germany in seeking a greener fuel for heavy industry.

The government in Madrid has a roadmap to build 4 gigawatts of green hydrogen capacity by 2030 and is expected to announce Cabinet approval of the program on Tuesday, according to Sara Aagesen, the secretary of state of energy. The program would require an investment of 8.9 billion euros ($10.5 billion) within the next decade.

... Hydrogen, if it’s made with renewables, could replace oil, natural gas and coal and help eliminate about a third of emissions from industries like steel and cement by mid-century, according to BloombergNEF. The processes to make green hydrogen aren’t yet economically viable without government support.

...
Key to scaling up green hydrogen are electrolyzers, machines powered by electricity that separate the hydrogen atoms in water from the oxygen. At the moment, electrolyzers in Spain have a capacity to make about 2.7 megawatts of hydrogen. The plan includes a target to build large-scale units that can each make as much as 100 megawatts.

The government wants these new plants to be built in places where other types of factories have been recently closed to ensure that the EU-sponsored concept of “just transition” is embedded in the hydrogen plan, Aagesen said.
Just like AOC's Green New Deal resolution. :D

A resolution that neglects renewable-energy synfuels, I must say.

JR East, Hitachi and Toyota to Develop Hybrid (Fuel Cell) Railway Vehicles Powered by Hydrogen | Corporate | Global Newsroom | Toyota Motor Corporation Official Global Website - "Test vehicles to be developed by combining railway and automotive technologies"

Railcars that use Li-ion batteries and hydrogen fuel cells.
The main circuit storage battery is charged by electric power from the fuel cell device and by capturing and converting energy to electric power using regenerative braking. The hybrid drive system supplies the electric power to the traction motors from both the fuel cell device and the main circuit storage battery, controlling the movement of the wheels.

Maximum speed of the train will be 100 km/h, with acceleration of 2.3 km/h/s. Range will be approximately 140 km.
This will be an alternative to diesel railcars. From the looks of it, they will be building self-propelled railcars for intercity service, something common in many places in the world, even if rare in the US. Some US suburban railroads have "diesel multiple unit" railcars, but that's it.

It could also be an alternative to diesel locomotives, complete with storing the hydrogen in tank cars.

I'm getting a buzz about ammonia also. It's an emerging synfuel that I didn't expect.

Green Ammonia Market: a New Era for Energy and Power Industry - Energy Post - looks like it is about using renewable-energy electrolysis hydrogen to make ammonia with the Haber-Bosch process.

Ammonia on route to fuel ships and planes
So-called green ammonia is made by reacting nitrogen separated from air with hydrogen made by wind- or solar-powered water electrolysis. It could be an environmentally friendly fertilizer or, backers say, a safe, low-emissions fuel for ships and planes.

...
Green ammonia would be a cheaper fuel for the shipping industry than hydrogen made from renewable energy because it is easier to store and can be burned in standard internal combustion engines. Nitrogen oxides—the only greenhouse gases emitted by the combustion of ammonia—could be eliminated by installing catalytic systems, the Danish firm states.

...
Green ammonia is also being lined up as a fuel for airplanes. The British aircraft-engine manufacturer Reaction Engines says it is working on a fuel system in which ammonia is exposed to a catalyst that splits it into nitrogen and hydrogen, with the latter burned in the aircraft engine.

Ammonia has the advantage over hydrogen in that it can be stored in an aircraft’s wing, as kerosene is today. Ammonia is, however, less energy dense than kerosene, so its use would be limited to short-haul flights.
 
Marine Sector Turns to Ammonia to Decarbonize Shipping | Greentech Media
Moving away from fossil fuels in shipping will require different approaches according to the type of vessel involved, experts say. Commuter ferries such as those in operation in Washington state are already moving toward battery power.

Elsewhere, compressed or liquefied green hydrogen could be an option for ships that are able to refuel regularly. But for vessels that spend days or weeks at sea, such as tankers, super trawlers or cargo ships, the size of the fuel tanks needed for hydrogen would be prohibitive.

Another possibility is for the industry to rely on synthetic diesel or other carbon fuels produced using renewable energy. In this instance, though, the problem is cost.

Synthetic diesel would cost approximately twice as much as green hydrogen in terms of energy on a megajoule-per-megajoule basis, said Niels de Vries, lead naval architect at C-Job Naval Architects of the Netherlands.
The days of steam propulsion are long gone, with the exception of ships powered by nuclear reactors.

These days, even the biggest ships are powered by diesel engines. The larger ships use bunker fuel, a bottom-of-the-barrel fuel in a very literal sense. It is what's left over after the volatile hydrocarbon fractions have been boiled off from crude oil.

That article discussed refitting existing ship engines to use ammonia. It has a boiling point of -33 C, making it much easier to store than hydrogen. However, it is not as energy-dense as hydrocarbon fuels, meaning larger fuel tanks or more frequent refilling.

Differences in carbon emissions reduction between countries pursuing renewable electricity versus nuclear power | Nature Energy
Two of the most widely emphasized contenders for carbon emissions reduction in the electricity sector are nuclear power and renewable energy. While scenarios regularly question the potential impacts of adoption of various technology mixes in the future, it is less clear which technology has been associated with greater historical emission reductions. Here, we use multiple regression analyses on global datasets of national carbon emissions and renewable and nuclear electricity production across 123 countries over 25 years to examine systematically patterns in how countries variously using nuclear power and renewables contrastingly show higher or lower carbon emissions. We find that larger-scale national nuclear attachments do not tend to associate with significantly lower carbon emissions while renewables do. We also find a negative association between the scales of national nuclear and renewables attachments. This suggests nuclear and renewables attachments tend to crowd each other out.
The ScienceDaily article stated
The researchers, using World Bank and International Energy Agency data covering 1990-2014, found that nuclear and renewables tend to exhibit lock-ins and path dependencies that crowd each other out, identifying a number of ways in which a combined nuclear and renewable energy mix is incompatible.

These include the configuration of electricity transmission and distribution systems where a grid structure optimized for larger scale centralized power production such as conventional nuclear, will make it more challenging, time-consuming and costly to introduce small-scale distributed renewable power.

Similarly, finance markets, regulatory institutions and employment practices structured around large-scale, base-load, long-lead time construction projects for centralized thermal generating plant are not well designed to also facilitate a multiplicity of much smaller short-term distributed initiatives.
Nuclear reactors have had over half a century to displace fossil-fuel electricity generation, but their success has been very limited. But here come renewable sources that come from behind with the vigor of new technologies, and they are succeeding. Like building a 2-gigawatt solar farm in only 4 months.

A few decades ago there was interest in returning to sail power for cargo ships hauling non-perishable cargo. Ships were designed with very different ideas for sails that would only need a very small crew to operate. If I remember correctly, one was a seven mast ship with computer controlled veins for sails. Of course, the driving motivation was it would be cheaper to operate as it would eliminate fuel costs. I have heard that Sweden is currently thinking of building a sail powered cargo ship, whether it's true or not or how serious they are, I don't know.
