The world’s first hydrogen-powered commercial passenger ferry will start operating on San Francisco Bay as part of plans to phase out diesel-powered vessels and reduce planet-warming carbon emissions, California officials said Friday, demonstrating the ship.
The 70-foot (21-meter) catamaran called the MV Sea Change will transport up to 75 passengers along the waterfront between Pier 41 and the downtown San Francisco ferry terminal starting July 19, officials said. The service will be free for six months while it's being run as part of a pilot program, reported The Associated Press.
“The implications for this are huge because this isn’t its last stop," said Jim Wunderman, chair of the San Francisco Bay Area Water Emergency Transportation Authority, which runs commuter ferries across the bay. "If we can operate this successfully, there are going to be more of these vessels in our fleet and in other folks’ fleets in the United States and we think in the world.”
Sea Change can travel about 300 nautical miles and operate for 16 hours before it needs to refuel. The fuel cells produce electricity by combining oxygen and hydrogen in an electrochemical reaction that emits water as a byproduct.
The technology could help clean up the shipping industry, which produces nearly 3% of the world’s total greenhouse gas emissions, officials said. That’s less than from cars, trucks, rail or aviation but still a lot — and it’s rising.
Frank Wolak, president and CEO of the Fuel Cell & Hydrogen Energy Association, said the ferry is meaningful because it’s hard to reduce greenhouse gas emissions from vessels.
“The real value of this is when you multiply out by the number of ferries operating around the world,” he said. “There’s great potential here. This is how you can start chipping away at the carbon intensity of your ports.”
Backers also hope hydrogen fuel cells could eventually power container ships.
The International Maritime Organization, which regulates commercial shipping, wants to halve its greenhouse gas releases by midcentury.
As fossil fuel emissions continue warming Earth’s atmosphere, the Biden administration is turning to hydrogen as an energy source for vehicles, manufacturing and generating electricity. It has been offering $8 billion to entice the nation’s industries, engineers and planners to figure out how to produce and deliver clean hydrogen.
Environmental groups say hydrogen presents its own pollution and climate risks.
For now, the hydrogen that is produced globally each year, mainly for refineries and fertilizer manufacturing, is made using natural gas. That process warms the planet rather than saving it. Indeed, a new study by researchers from Cornell and Stanford universities found that most hydrogen production emits carbon dioxide, which means that hydrogen-fueled transportation cannot yet be considered clean energy.
Yet proponents of hydrogen-powered transportation say that in the long run, hydrogen production is destined to become more environmentally safe. They envision a growing use of electricity from wind and solar energy, which can separate hydrogen and oxygen in water. As such renewable forms of energy gain broader use, hydrogen production should become a cleaner and less expensive process.
The Sea Change project was financed and managed by the investment firm SWITCH Maritime. The vessel was constructed at Bay Ship and Yacht in Alameda, California, and All-American Marine in Bellingham, Washington.

A massive wildfire near Paris has torched swathes of a forest that has lured admirers for centuries, from royal hunting parties to impressionist painters, rock climbers and nature lovers.

Fontainebleau is no stranger to fire but this inferno -- fanned by strong winds and heatwave conditions -- is among the worst in decades, destroying nearly five percent of the 25,000-hectare (61,800 acre) forest.

- Prehistory and royalty -

Fontainebleau attracts between 15 and 18 million visitors a year -- nearly twice as many as the Louvre museum in Paris.

Most travel from the French capital 60 kilometers (40 miles) away but 30 percent come from outside France.

Rock art dating back to prehistoric times has been discovered in its caves.

Fontainebleau became a royal estate around the year 1000 under Robert II "the Pious" of France. Later, a grand palace was built to host hunting parties.

The hunting paths are still used today by firefighters to access the forest, said Sophie David, an archaeologist who heads the environment and visitor services department at the state-run National Forestry Office.

Around 200 years ago, swathes of the forest had been cleared for agriculture, reducing it to roughly one-third of its current size.

"In the 19th century, trees were planted to fill in the gaps. Pines were chosen, trees with shallow roots" capable of growing in Fontainebleau's sandy soil, said David.

The character of this new, more open forest was captured by the painters of the Barbizon Impressionist school.

The invention of the paint tube, and rise of leisure travel among France's growing bourgeoisie, helped make Fontainebleau attractive for walkers and artists.

"The railway arrived in 1849 and the world's first signposted (hiking) trails were created" in Fontainebleau shortly after, said David.

Rosa Bonheur, a renowned French artist of this era, painted her iconic "Fairy Pond" in Fontainebleau.

- Nature hotspot -

The forest is home to oak and beech woods as well as coniferous forests, open heathland, fossil dunes, ponds and wetlands.

Thirty million years ago, the forest was an ocean. As the sea receded, it left behind sand which, over millennia, formed the sandstone blocks that now attract rock climbers.

"What makes the Fontainebleau massif unique is the diversity of its landscapes and the richness of its biodiversity," said David.

It hosts more than 6,500 known animal species -- hares and deer to birds like warblers and tawny owls and rare insects, such as the stag beetle.

UNESCO designated Fontainebleau a "biosphere reserve" in 1998.

Around 1,000 hectares are designated strict nature reserves, with no human intervention. One of those reserves has been among the hardest hit by the fire.

- Old foe -

Fire was first recorded in Fontainebleau in the 13th century.

David said detailed records had been kept since 1863 and the current blaze -- which has burned some 1,000 hectares already -- was among the largest in the history books.

In the early 20th century, surveillance towers were erected to address the problem, helping reduce the area burned.

More recently, six 10,000-litre (2,650-gallon) water tanks have been installed in the forest to enable a more rapid response to fires.

Around 30 fires break out each year, most often caused by cigarette butts or unauthorized campfires.

For the past two years, the fire service has been testing an AI surveillance system which can detect smoke and quickly locate the source to notify the fire department.


In a Sweet Discovery, Astronomers Find Sugar Lurking in the Space Between Stars

The space between stars just got a little sweeter.

Astronomers have detected a type of sugar in space that's also found in raspberries and self-tanners. The sugar, called erythrulose, lurks in what's called the interstellar medium: thin clouds of gas and dust littered between stars.

Sugar does more than sweeten tea and powder doughnuts. Different varieties fuel our cells and even make up DNA. Scientists are itching to know how sugars form because they're a key ingredient for life as we know it.

Using two dish-shaped radio telescopes in Spain, researchers collected data from a large gas cloud near the center of the Milky Way. They identified the sugar in gas form by comparing telescope signals to samples in the lab. It's the latest kind of sugar detected in space — in a region crossed by NASA's twin Voyager, the farthest spacecraft to ever travel from Earth.

The results were published Monday in the journal Nature Astronomy.

Scientists have found interesting chemistry in our galaxy, including building blocks for genetic material and parts of the cell. They spotted a cousin to table sugar near the center of the Milky Way about 25 years ago, and black grains from asteroid Bennu retrieved by NASA’s Osiris-Rex spacecraft yielded other sugars, including a key DNA ingredient.

The latest sugar isn’t essential for life, but can easily convert to a form that’s thought to be crucial to kick-starting life on Earth. And it’s one of the most complex sugars spotted so far, said astrophysicist Erika Hamden with the University of Arizona.

It's “a pristine example of the stuff that’s just floating out in the galaxy,” said Hamden, who had no role in the new research.

Researchers want to look for more sugars in space and learn about how they convert to different forms.

Finding them in one spot means they're likely also hiding in distant corners of the galaxy along with other important bits, said study author Izaskun Jiménez-Serra, an astrophysicist at the Center for Astrobiology in Spain.

“The key ingredients for the origin of life could be present in other regions across the galaxy, opening the possibility for life to develop elsewhere in the universe,” Jiménez-Serra said.

The bodies of two Romanian climbers missing since last week were found Monday in the Gran Paradiso massif in the Italian Alps, authorities told AFP.

The two Romanian nationals whose ages have not been disclosed had not made contact since leaving a mountain refuge on July 9, according to authorities in the Aosta Valley, a northern region bordering Switzerland and France.

After several days of helicopter searches, their bodies were found Monday morning at the bottom of a crevasse about 20 metres deep, regional authorities said.

Gran Paradiso rises to 4,061 metres within Italy's oldest national park.

Mountain accidents are common in Italy: in 2025, they caused 528 deaths, an increase of 13 percent compared with the 466 fatalities recorded in 2024, according to the Italian National Alpine and Speleological Rescue Corps (CNSAS).
