Ørsted and Equinor Sue Challenging U.S. Stop-Work Orders for Offshore Wind Farms

Two more offshore wind farms filed suits against the Trump administration after they were ordered in late December to stop work due to “national security” concerns. Danish offshore wind energy developer Ørsted amended its existing complaint in U.S. District Court to challenge the Trump administration’s stop-work order on the nearly completed Revolution Wind project, while Norwegian company Equinor filed a civil suit on January 2 for the Empire Wind project. Both companies said they would file motions for a preliminary injunction against the Department of the Interior’s Bureau of Ocean Energy Management (BOEM), which issued the stop-work order on December 22.

Both companies assert that the suspension order “violates applicable laws,” and say it is causing “substantial harm” to their projects and companies. They are following Dominion Energy, which filed suit last week to challenge the stop-work order for its Coastal Virginia Offshore Wind. BOEM, at the direction of the Secretary of the Interior, Doug Burgum, issued the stop-work order for these projects, as well as Avangrid’s Vineyard Wind 1, and Sunrise Wind, which is also being developed by Ørsted. 

The Trump administration asserted that new data showed the potential for radar interference and clutter from the turbine blades and towers. At the beginning of the week, the court hearing the Dominion Energy case ordered the Department of the Interior to provide the confidential study, which it says is the basis for the order, but refused to issue a temporary restraining order for Dominion Energy. The court converted the case to a motion for a preliminary injunction, which will be heard in January.

Each of the companies contends in their legal action that the projects spent years in permitting and engaged in years-long consultation with the U.S. Department of Defense [War] Military Aviation and Installation Assurance Clearinghouse to address potential impacts to national security and defense capabilities. The companies have indicated that they were willing to work constructively with the administration for a durable resolution of any concerns.

Revolution Wind told the court that it is in advanced stages of construction, now approximately 87 percent complete. The project they report has spent and committed billions of dollars, noting that it was expected to start generating power as early as January and would be completed in 2026. Similarly, Dominion Energy says Coastal Virginia was nearing its first power while Equinor reports Empire Wind is more than 60 percent complete. Equinor says it has invested over $4 billion, of which $2.7 billion has been drawn under the project financing. Empire Wind is also investing in the redevelopment of the South Brooklyn Marine Terminal.

For Ørsted, this is the second time in months that Revolution Wind is being forced to seek court interventions owing to the administration’s efforts to stop the project that is located approximately 15 miles south of Rhode Island and 32 miles southeast of Connecticut, with power contracts with both states. In August last year, BOEM ordered the developer to halt ongoing activities to allow time for it to address what it said were concerns that had arisen about the permitted process. The company, however, got a reprieve a month later after a federal court in D.C. ruled in its favor, allowing construction to resume.

In its amended complaint, Revolution Wind highlights that it is in the final stages of construction with all offshore foundations, its export cabling, two offshore substations, and 58 of 65 wind turbines already installed. The wind farm, which has a capacity to generate 704 MW, is contracted to deliver electricity to Rhode Island (400 MW) and Connecticut (304 MW).

While Ørsted has opted to sue BOEM over the order on Revolution Wind, the developer is evaluating options on Sunrise Wind, a separate project that it wholly owns. When it received approvals in June 2024, Sunrise Wind was touted as the largest offshore wind project in New York with a capacity of 924 MW, enough to power nearly 600,000 homes. Located about 30 miles east of Montauk and featuring 84 large turbines, the project was expected to be operational in 2027.?Ørsted highlighted that among the options being evaluated are engagement with relevant agencies and stakeholders and legal proceedings.


Orsted files lawsuit against US suspension of wind turbine leases

Danish offshore wind energy firm Orsted said Friday its US joint venture had filed a lawsuit challenging the suspension of the lease for its nearly-completed project off the coast of New England.

The US Interior Department on December 22 said it had paused leases for all five of the country’s offshore wind projects under construction, citing unspecified national security risks and casting new doubt over the future of an industry detested by President Donald Trump.

Orsted has a 50 percent stake in the Revolution Wind project alongside a renewables infrastructure developer that is part of the BlackRock investment group.

The park of 65 turbines off the coast of Rhode Island is 87 percent complete and had been set to go online this year and provide power for more than 350,000 homes, according to Orsted.

“While Revolution Wind continues to seek to work constructively with the Administration and other stakeholders towards an expeditious and durable resolution of this matter, it believes that the lease suspension order violates applicable law,” Orsted said in a statement.

The Revolution Wind project faces substantial harm from a continuation of the lease suspension order, it said, and noted an earlier suspension of the project by the Trump administration in August was overturned by the courts.

“As a result, litigation is a necessary step to protect the rights of the project,” it added.

The move by the Interior Department came only weeks after a judge ruled that a blanket ban on new offshore permits — signed by Trump on his first day in office in January — was illegal.

The Interior Department did not specify what the risks were, but it noted that the Department of Energy had also previously identified potential issues related to radar interference.

Orsted said that Revolution Wind secured all required federal and state permits in 2023 following extensive reviews that lasted years, which included consultations with the US military.

“Those consultations resul

ted in a fully executed formal agreement between the Department of War, the Department of the Air Force, and Revolution Wind outlining mitigation measures” to be undertaken as part of the project, Orsted said.

Trump has long complained that wind turbines ruin views and are expensive.

In addition to his order attempting to ban new wind farm permits, Trump’s administration has also moved to block all federal loans for wind energy.

Battle brews as energy developer takes on Trump admin over 'unlawful' stop-work order
 Common Dreams
January 2, 2026 



Developers behind two of the five offshore wind projects recently targeted by the Trump administration took action in federal court this week, seeking preliminary injunctions that would enable construction to continue while the legal battles play out.

Empire Offshore Wind LLC filed a civil lawsuit in the US District Court for the District of Columbia on Friday, challenging the Department of the Interior’s (DOI) December 22 stop-work order, which the company argued is “unlawful and threatens the progress of ongoing work with significant implications for the project” off the coast of New York.

“Empire Wind is more than 60% complete and represents a significant investment in U.S. energy infrastructure, jobs, and supply chains,” the company highlighted. “The project’s construction phase alone has put nearly 4,000 people to work, both within the lease area and through the revitalization of the South Brooklyn Marine Terminal.”

The filing came just a day after a similar one in the same court on Thursday from the joint venture between Skyborn Renewables and the Danish company Ørsted, which is developing Revolution Wind off Rhode Island and Connecticut. That project is approximately 87% complete and was expected to begin generating power as soon as this month.

“Sunrise Wind LLC, a separate project and wholly owned subsidiary of Ørsted that also received a lease suspension order on December 22, continues to evaluate all options to resolve the matter, including engagement with relevant agencies and stakeholders and considering legal proceedings,” the Danish firm said. That project is also off New York.

As the New York Times noted Friday: “At stake overall is about $25 billion of investment in the five wind farms. The projects were expected to create 10,000 jobs and to power more than 2.5 million homes and businesses.”



The other two projects targeted by the Trump administration over alleged national security concerns are Vineyard Wind 1 off Massachusetts and Coastal Virginia Offshore Wind. The developer of the latter, Dominion Energy, launched a legal challenge in federal court in Virginia the day after the DOI’s lease suspension order, and a hearing is scheduled for this month.

“Delaying the project will lead to increased costs for customers and threaten long-term grid reliability,” Dominion spokesperson Jeremy Slayton told NC Newsline on Tuesday. “Given the project’s critical importance, we have a responsibility to pursue every available avenue to deliver the project as quickly and at the lowest cost possible on behalf of our customers and the stability of the overall grid.”

President Donald Trump’s public opposition to offshore wind energy dates back to before his first term as president, when he unsuccessfully fought against the Aberdeen Bay Wind Farm near his golf course in Scotland. Since entering US politics, the Republican has taken money from and served the interests of fossil fuel giants while waging war on renewable power projects and lying about the climate emergency.

As the Times detailed:

Mr. Trump has falsely claimed that wind farms kill whales (scientists have said there is no evidence to support that) and that turbines “litter” the country and are like “garbage in a field”...

This week President Trump posted on social media a photo of a bird beneath a windmill and suggested it was a bald eagle killed in the United States by a wind turbine. “Windmills are killing all of our beautiful Bald Eagles,” the president wrote. It was also posted by the White House and the Department of Energy.

The post turned out to be a 2017 image from Israel, and the animal was likely a kestrel. On Friday Mr. Trump posted on Truth Social again, this time an image of birds flying around a wind turbine, that read, “Killing birds by the millions!”

While the DOI did not respond to the newspaper’s request for comment, and the department referred the Hill to its December statement citing radar interference concerns, White House spokesperson Taylor Rogers told NC Newsline earlier this week that Trump has made clear that he believes wind energy is “the scam of the century.”

“For years, Americans have been forced to pay billions more for the least reliable source of energy,” Rogers said. “The Trump administration has paused the construction of all large-scale offshore wind projects because our number one priority is to put America First and protect the national security of the American people.”

Meanwhile, climate campaigners and elected Democrats have blasted the Trump administration’s attacks on the five offshore projects, warning of the economic and planetary consequences. Democratic senators have also halted permitting reform talks over the president’s “reckless and vindictive assault” on wind power.

Additionally, as Common Dreams reported Monday, the watchdog group Public Employees for Environmental Responsibility warned congressional committees that the DOI orders are “not legally defensible” and raise “significant” questions about conflicts of interest involving a top department official’s investments in fossil gas.









Norway closes in on objective of 100% electric car sales

Tax exemptions have helped boost sales of electric cars in Norway - Copyright AFP/File Jonathan NACKSTRAND

Norway came close to its objective of selling only zero-emission cars in 2025, with electric vehicles accounting for 95.9 percent of new registrations.

Although Norway is western Europe’s largest exporter of petroleum products, it has led the shift to electric vehicles, setting a non-binding target of selling only zero-emission vehicles in 2025 — then years ahead of the neighbouring European Union.

A record 179,549 personal vehicles were registered in 2025, beating the previous high set in 2021, the Norwegian Road Federation (OFV) said on Friday.

Electric vehicles accounted for 97.6 percent of sales in December.

“While car sales are traditionally strong at the end of the year, there is no doubt the VAT tax change on January 1, 2026 spurred many people to buy a new electric vehicle before the end of the year,” OFV director Geir Inge Stokke said in a statement.

The Norwegian government decided to lower the exemption from VAT tax from 500,000 kroner ($49,600) to 300,000 kroner from the start of 2026.

The elimination of the exemption, initially planned for 2027, is expected to be pushed back to 2028.

Tesla consolidated its leading position in the Norwegian market, accounting for 19.1 percent of total registrations.

A record 34,285 new Teslas were registered in Norway last year according to the OFV, as the brand escaped the drop in sales it has seen elsewhere in Europe due to the controversies stoked by its founder Elon Musk.

Chinese carmakers also boosted their share of the Norwegian market, climbing from 10.4 percent in 2024 to 13.7 percent in 2025.
US Electric Grid Heading Toward ‘Crisis’ Thanks to AI Data Centers

“No good comes of having an AI data center near you.”

The massive energy needs of artificial intelligence data centers became a major political controversy in 2025, and new reporting suggests that it will grow even further in 2026.

CNBC reported on Thursday that data center projects have become political lightning rods among politicians ranging from Sen. Bernie Sanders (I-Vt.) on the left to Republican Florida Gov. Ron DeSantis on the right.

However, objctions to data centers aren’t just coming from politicians but from ordinary citizens who are worried about the impact such projects will have on their local environment and their utility bills.

CNBC noted that data centers’ energy needs are so great that PJM Interconnection, the largest US grid operator that serves over 65 million people across 13 states, projects that it will be a full six gigawatts short of its reliability requirements in 2027.

Joe Bowring, president of independent market monitor Monitoring Analytics, told CNBC that he’s never seen the grid under such projected strain.

“It’s at a crisis stage right now,” Bowring said. “PJM has never been this short.”

Rob Gramlich, president of power consulting firm Grid Strategies, told CNBC that he expects the debate over data centers to become even more intense this year once Americans start getting socked with even higher utility bills.

“I don’t think we’ve seen the end of the political repercussions,” Gramlich said. “And with a lot more elections in 2026 than 2025, we’ll see a lot of implications. Every politician is going to be saying that they have the answer to affordability and their opponents’ policies would raise rates.”

Concerns about data centers’ impact on electric grids are rising in both red and blue states.

The Austin American-Statesman reported on Thursday that a new analysis written by the office of Austin City Manager TC Broadnax found that data centers have the potential to overwhelm the city’s system given they are projected to need more power than can possibly be delivered with current infrastructure.

“The speed in which AI is trying to be deployed creates tremendous strain on the already tight resources in both design and construction,” says the analysis, which noted that some proposed data centers are seeking more than five gigawatts, which is more than the peak load for the entire city.

In New York, local station News 10 reported last year that the New York Independent System Operator is estimating that the state’s grid could be 1.6 gigawatts short of reliability requirements by 2030 thanks in large part to data centers.

Anger over proposed data centers has even spread to President Donald Trump’s primary residential home of Palm Beach County, Florida, where local residents successfully postponed the construction of a proposed 200-acre data center complex.

According to public news station WLRN, locals opposed to the project cited “expected noise from cooling towers, servers, and diesel generators, along with heavy water use, pollution concerns, and higher utility costs” when petitioning Palm Beach County commissioners to scrap the proposal.

Corey Kanterman, a local opponent of the proposed data center, told WLRN that his goal is to shut the project down entirely.

“No good comes of having an AI data center near you,” Kanterman said. “Put them in the location of least impact to the environment and people. This location is not it.”
UK sees record-high electricity from renewables in 2025: study

Britain produced a record-high amount of electricity from renewable energy last year, a study revealed on Friday.

Wind, solar and biomass power combined to supply 47 percent of the country’s electricity in 2025, climate and energy website Carbon Brief said in its report.

This was greater than gas, which supplied 28 percent of UK electricity, while nuclear was in third with 11 percent of production.

The amount of gas used for electricity rose after the country shut its last coal-fired power station in late 2024, the study said, adding that nuclear power reached its lowest level in 50 years, in part owing to outages.

“Overall, UK electricity became slightly more polluting in 2025,” concluded Carbon Brief, adding that the nation’s electricity exports grew and imports fell last year.

It added that the UK saw a one-percent rise in electricity demand “after years of decline”, as electric vehicles, heat pumps and data centres connected to the grid in larger numbers.

Britain is one of the leading players in renewable energy in Europe owing to onshore and offshore wind power.

The country has set a target to reduce its greenhouse gas emissions by at least 81 percent by 2035 compared to 1990 levels and is aiming to be carbon neutral by the middle of the century.

Opinion: Iran — Teetering, in real trouble, and Trump wants to ‘rescue’ protesters

The current situation in Iran is far more complex than headlines about protests and political discontent. The country is in big trouble.

Water resources are a dangerous major issue. A backlog of many dated infrastructure problems and a top-heavy social structure, common in theocracies, isn’t helping.

Iran has another serious problem. It’s a unique Shia nation, largely surrounded by Sunni nations with which relations are typically strained. Neighbors include the Taliban in Afghanistan and the ever-erratic Pakistan.

Iran’s belligerent position in relation to the West has been in place since 1979. That hasn’t helped much, either. Sanctions, the slow drip of obsolescence, and constant involvement with groups like Hamas outside Iran stretch money and resources. The confrontation with Israel also largely backfired.

The protests aren’t cosmetic. They’re systemic. You could say they were inevitable. They reflect current Iranian realities. When the ayatollahs came to power, you could easily argue that Iran lost a repressive regime. The West was seen as the enemy as much for supporting the old regime as for any other reason. That’s ancient history.

That was nearly 3 generations ago. Things are very different now. Iran’s extremely difficult problems are all here and now, at critical levels, and getting worse.

Enter Donald Trump, riding a white press release about rescuing protesters. Iran isn’t happy about it. That’s likely to get very ugly in a hurry in any sort of exchange of pleasantries with the US.

Iran is not toothless. It has a global reach through extended networks. It is quite capable of hitting targets around the world, not just the Middle East. It can’t win a direct confrontation with the US, but it can hit back. It is also more than capable of funding an ongoing Hamas-style underground war for decades.

What exactly can be achieved by military action by the US? Not much on the ground in Iran.

Iranian internal security is genuinely tough, nationwide, and entrenched. It works directly for the regime. It won’t be affected at all by strikes. Regime change is extremely unlikely unless a combination of internal Iranian social stress fractures and a true popular uprising occurs.

Much worse, any US action can and will be used as an excuse for retaliation against the protesters. It could trigger a severe national crackdown.

An American involvement could appeal to Iran’s hostile neighbors, like Saudi Arabia. It’s more of an entry in a popularity contest than any actual assistance to Iranian protesters.

Nor is there anything like a clear indication of American strategic objectives. A purely symbolic gesture could just get a lot of Iranians killed. Any such commitment will also be extremely expensive for the US. The Middle East has been soaking up US money like a sponge for decades.

The default expected strategy is more likely to be a very half-baked, unworkable attempt at regime change. The Iranian protesters may be much more than a bit skeptical of this sudden altruism on the part of the US.

It’ll also be very hard to sell an Iranian war as an “America First” initiative. More big money going anywhere but America will antagonize most Americans very effectively. Any degree of prolonged US military involvement in Iran will dwarf the recent bailout of US farmers by multiples.

This looks very much more like grandstanding and gaslighting than any sort of considered initiative or integrated strategy.

It looks frivolous and futile. What a surprise.

Dress for success: Mexican president’s ideological attire


By AFP
Published January 2, 2026

Leticia PINEDA

Mexican President Claudia Sheinbaum’s wardrobe is more than a statement of style; it has become known as a canvass for her political message of advancing women’s and Indigenous rights.

The leftist leader, Mexico’s first woman president, proudly uses small-scale, local tailors and shuns “those brands that are super expensive,” in her own words.

Rather, she supports “the weavers, the embroiderers, all those who use backstrap looms in our country — mostly women — who are a source of national pride,” the 63-year-old recently told journalists.

The Mexican government has taken on famous brands such as Adidas, Shein, Zara and Carolina Herrera for the alleged cultural appropriation of traditional designs.

And in her own fashion choices, Sheinbaum has similarly chosen to give credit where she says it’s due, and to uplift those she can along the way.

“Her ideology has always been very focused on people’s rights, on equality; even in her style of dress,” according to Mexican image consultant Gabriela Medina.

– ‘Feminist resistance’ –

Sheinbaum was included on The New York Times list of 67 most stylish people of 2025 — the only politician in the group.

One person responsible for her look is Olivia Trujillo, who runs a small tailor shop from her home in the bustling neighborhood of San Pedro Martir on the outskirts of Mexico City.

“Her favorite colors, without a doubt, I would say are purple and burgundy,” the 63-year-old pattern-maker and tailor told AFP amid her sewing machines and a mannequin on which she assembles the presidential wardrobe.

Trujillo was recently called to the National Palace for the final fitting of a purple dress with finely embroidered flowers that Sheinbaum wore in December to her first face-to-face meeting with US President Donald Trump and Canadian Prime Minister Mark Carney in Washington.

“The color purple is associated with power, authority, luxury, royalty, spirituality, and sobriety,” Medina said of Sheinbaum’s choice.

It is also the color “that the feminist resistance movement has embraced,” she added.

– ‘Image shapes authority’ –

Another emblematic Sheinbaum choice was the dress she wore for her October 2024 swearing-in: a knee-length, ivory creation with embroidered wildflowers cascading down one side.

The upper part was left plain “so that the presidential sash would stand out,” recalled Trujillo.

The flowers were painstakingly hand-sewn onto the fabric by Claudia Vazquez, a 43-year-old Zapotec Indigenous woman who told AFP she had nearly given up on embroidery, her first love.

Sheinbaum’s interest in her art had “changed her life,” the trained business administrator said in Oaxaca in southern Mexico, where she now plies her art.

In the country’s center, in the village of San Isidro Buen Progreso, lives another embroiderer whose services the president has enlisted.

Virginia Arce, 48, decorated the formal gown Sheinbaum wore in September when she became the first woman to give the Cry of Independence — a call for revolt against Spanish rule still celebrated every year.

“The president chose the tones and a bird she really liked –it was a swallow,” Arce recalled.

The task took her two months but the result was worth it when she saw the head of state step out onto the presidential balcony in her handiwork.

It was the day “that has brought me the most satisfaction,” said Arce.

Gender analyst Laura Raquel Manzo, points to the danger of stereotyping women by analyzing what they wear — traditionally not a scrutiny applied to male leaders.

In this case, however, ignoring Sheinbaum’s deliberate dress choices would be “to deny how image shapes authority,” said Manzo.
Is Ukraine endangered by elections?

Thursday 1 January 2026, by Vitaliy Dudin


What will be the election race in war-wounded Ukraine - a collapse of statehood or a breath of fresh air in a roughly sealed system adjusted to the service of oligarchs? The language, first and foremost, is about the parliamentary elections.

Whether the handling of the idea of elections in terms of parliamentary war is a bluff or truth, this news needs to be taken seriously.

As a person who has not once enforced the right to vote, I see elections in itself an illusory game that only legitimizes the will of the ruling class.

But restricting the right of millions of people to free will is absolutely detrimental to democracy. This leads to an accumulation of disappointment, controversy, and alienation. Tim is on a wave of total distrust in power, which no longer can be broken by a single distribution of 100,000 steps... No matter how, but citizens are gradually losing faith that they are the full-fledged masters of the country they defend with such sacrifice.

In principle, the authorities have reason to be interested in elections because they will instill a short-term sense of democracy holiday and relieve tension.

The people, too, have reasons to participate in the electoral process: it is a chance to put an end to the monopoly slavery and to put more worthy people into power who have demonstrated their virtues exactly during the invasion.

But many questions remain: freedom of agitation, voting security, polarization of society...
In my opinion, some of these hypothetical risks are clearly exaggerated. Often this is the unwillingness of a certain part of society to "get stuck" into this dirty history or an inability to offer an alternative to the existing consensus. Simply put, for a significant margin of liberal public it is much more convenient to criticize the government for corruption, because they cannot propose a meaningful AGENDA. All suggestions of changes are point-to-point / personnel nature or consistent with the government’s capital-centric rhetoric.

Instead, elections cannot be afraid of forces that are SOCIALly different from the ruling class: they oppose the oligarchy, for first counting of workers’ voices in the course of reforms and criticize capitalism’s destructive pauperizing influence. Of course, provided they are allowed to have their own party.

Therefore, I find the beginning of a debate about elections in the face of war useful if it allows for a broad range of public opinion. But alternatives to election procedures that can fuel the interest of the people to politics:

1) decentralization of power with the delegation of functions from parliament to local councils with gradual updating of the latter;

2) strengthening the advisory bodies such as public councils, so that they stop being decorative;

3) Guarantee of participation of employees in the supervisory councils of state monopolies for the construction of manufacturing democracy.

New study maps most sustainable and cost-effective hydrogen delivery options in Europe




Higher Education Press






Researchers from the Joint Research Centre (JRC) of the European Commission have published a comprehensive assessment in Frontiers in Energy comparing the technical, economic, and environmental impacts of different renewable hydrogen delivery options within Europe. The study, titled "Techno-economic and life-cycle assessment comparisons of hydrogen delivery options," provides crucial data for policymakers charting the course towards the EU’s 2050 carbon neutrality goal.

 

Research Background

The European Union aims to produce and import 10 million tonnes of renewable hydrogen each by 2030 to decarbonize sectors like transport and heavy industry. Achieving this requires establishing cost-effective and sustainable long-distance transport corridors. While hydrogen production is increasingly efficient, the optimal method for delivering it remains a complex multi-criteria challenge. This paper combines Techno-Economic Assessment (TEA) and Life Cycle Assessment (LCA) to address this gap.

 

Research Content and Key Findings

The study analyzed five hydrogen carriers—compressed hydrogen (C-H2), liquid hydrogen (L-H2), ammonia (NH3), methanol (MeOH), and Liquid Organic Hydrogen Carrier (LOHC)—assuming hydrogen is produced via renewable electrolysis in Portugal and transported to the Netherlands (a 2500 km distance) by ship or pipeline.

Key Findings:

  • Most Sustainable Options: The assessment identifies shipping liquid hydrogen (L-H2 by ship) and compressed hydrogen (C-H2 by pipeline) as the most economically and environmentally favorable pathways for long-distance transport within the reference European scenario.
  • Challenges of Chemical Carriers: Carriers like ammonia, methanol, and LOHC generally exhibit higher costs and greater environmental impacts. This is primarily due to the substantial additional energy and material requirements in the conversion steps (packing and unpacking the hydrogen into the carrier), which necessitate more renewable electricity infrastructure (e.g., extra solar panels).
  • Impact of Distance: For extended routes (10,000 km), liquid hydrogen maintains its advantage, while compressed hydrogen becomes less competitive due to increased fuel demand and vessel needs.

 

Research Significance

This comprehensive multi-criteria analysis provides valuable, harmonized insights for policymakers and stakeholders regarding sustainable hydrogen import pathways. By clearly identifying the trade-offs between cost and environmental burden—particularly the high impact associated with the energy-intensive conversion stages of chemical carriers—the findings support strategic decisions on investing in long-distance hydrogen infrastructure, such as repurposing existing natural gas pipelines for C-H2 transport. The study also highlights the need for continued research into reducing technological uncertainties and improving the environmental footprint of emerging hydrogen technologies.

 

The full research article is available in Frontiers in Energy (DOI: 10.1007/s11708-025-1041-1).

Beijing’s metro system could soon carry express parcels alongside commuters during quiet periods, according to a new operational blueprint published in Engineering. Researchers from Beijing Jiaotong University and East China Jiaotong University have designed a joint optimization model that simultaneously plans train timetables, rolling-stock circulation, and cargo loading while allowing trains to skip stations with low demand. The approach, tested on the Yizhuang Line, cut operating costs by up to 25% compared with conventional fixed-composition, all-stop services.

 

The study addresses the rapid rise in urban freight volumes—already 15 million parcels a day in Beijing—by repurposing surplus metro capacity outside peak hours. Instead of building costly underground logistics tunnels, the team treats the existing passenger network as a shared infrastructure where freight containers ride in dedicated carriages that can be coupled or uncoupled at terminal depots. Five train configurations are available, ranging from all-passenger to all-freight formations, each with a known operating cost and capacity.

 

A mixed-integer nonlinear programming (MINLP) model minimizes a weighted sum of train operating costs, passenger waiting penalties, and cargo delays. It enforces strict first-in-first-out rules for cargo groups, ensures that no passenger waits more than two trains, and guarantees that rolling-stock counts at each depot never drop below one. Skip-stop decisions are integrated directly into the timetable: a train omits a station only when both passenger and freight stopping modes allow it, shortening running times and reducing energy use.

 

To solve the large-scale problem, the researchers developed a variable neighborhood search (VNS) algorithm that alternates between shaking the timetable headways and refining skip-stop patterns. Numerical experiments on a six-station synthetic line and on the 14-station Yizhuang Line show that the VNS algorithm finds near-optimal solutions in minutes, whereas the commercial solver GUROBI struggles with gaps above 30% once more than 32 trains are scheduled.

 

During off-peak hours (11:00 a.m.–4:00 p.m.), the flexible composition plan deployed 16 small-passenger, eight mixed, and four small-freight trains, cutting total costs by reducing operating expenses by 19.9%. Only four passengers were briefly detained, and cargo delays averaged 10 minutes. When the same logic was applied across a full day with 150 trains per direction, morning-peak cargo groups experienced longer waits, but most of parcels still arrived within 40 minutes of their desired time.

 

The paper notes that skip-stop strategies must be calibrated to passenger flow: skipping stations with fewer than 100 arrivals during off-peak periods avoided mass detentions, whereas careless skipping could strand hundreds. They also note that legislation in some jurisdictions still prohibits mixed passenger-freight carriages, so the decoupled composition approach offers a legally viable compromise.

 

Future work will explore uncertainty in demand and dwell times, extend the model to entire metro networks, and incorporate passenger attitudes toward sharing space with freight. For now, the study demonstrates that with careful scheduling, today’s metro lines can quietly carry tomorrow’s parcels without adding a single new tunnel.
