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.

Brazilian Researchers Discover Dinosaur Fossil after Heavy Rains

A team of Brazilian scientists has discovered a skeleton of what they believe is one of the world’s oldest dinosaurs after heavy rains in the southern state of Rio Grande do Sul accelerated the natural process of erosion, The AP reported.

The fossil found next to a reservoir in the municipality of Sao Joao do Polesine is around 233 million years old, according to palaeontologist Rodrigo Temp Müller, who led the team from the Federal University of Santa Maria that found the bones in May.

The claims have not been verified by other scientists or published in a scientific journal.

The researcher believes the dinosaur lived during the Triassic period, when all continents were part of a single land mass called Pangaea. Dinosaurs are thought to have first evolved at that time.

The apex predator discovered in Rio Grande do Sul belongs to the group known as Herrerasauridae – a family of dinosaurs that used to wander across lands that now make up present-day Brazil and Argentina, according to a fact sheet about the discovery shared with The AP.

The size of the bones reveals that the dinosaur would have reached around 2.5 meters (8.2 feet) in length, according to the document.

Rodrigo Temp Müller said that he and his team were “very excited and surprised” by their findings.

After around four days of excavations, the group of researchers transported a block of rock containing the specimen back to the laboratory, where they ran tests.

“Initially it seemed like just a few isolated bones, but as we exposed the material, we were able to see that we had an almost complete skeleton,” Müller said.

The expert hypothesizes that their discovery is the second most complete skeleton for this type of dinosaur.

Researchers will now carry out investigations to determine whether the fossil belongs to an already-known species or if they have found a new kind. That work is expected to take several months, as the process is meticulous to ensure no damaged is caused.

Fossils are more likely to appear after rains, as water exposes the materials by removing the sediment that covers them, in a phenomenon known as weathering.

Rio Grande do Sul saw record amounts of rainfall earlier this year. That caused devastating floods in May that killed at least 182 people, according to a toll published by the state’s civil defense on July 8.

Extreme weather events are made more likely by climate change, principally caused by the burning of oil, gas and coal.

Müller said that more fossils are appearing because of the heavy rains, which has launched a race against time to rescue the materials before they are ruined.

In the field, his team observed “a leg bone and a pelvis bone in the pelvic region that were already being destroyed due to the rain,” he said.

Müller hopes the discovery will contribute to elucidate the origins of dinosaurs.

“Having new fossils that are so well preserved certainly helps us better understand this topic that is still much debated,” he said.
