Underwater turbine spinning for 6 years off Scotland's coast is a breakthrough for tidal energy
Tidal turbines are visible at the MeyGen tidal site located in the Inner Sound of the Pentland Firth, a narrow channel of water between the Scottish mainland and Stroma Island. By JENNIFER McDERMOTT Submerged in about 40 meters of water off Scotland's coast, a turbine has been spinning for more than six years to harness the power of ocean tides for electricity — a durability mark that demonstrates the technology's commercial viability. Keeping a large, or grid-scale, turbine in place in the harsh sea environment that long is a record that helps pave the way for bigger tidal energy farms and makes it far more appealing to investors, according to the trade association Ocean Energy Europe. Tidal energy projects would be prohibitively expensive if the turbines had to be taken out of the water for maintenance every couple of years. Tidal energy technologies are still in the early days of their commercial development, but their potential for generating clean energy is big. According to the National Renewable Energy Laboratory, marine energy, a term researchers use to refer to power generated from tides, currents, waves or temperature changes, is the world's largest untapped renewable energy resource. The MeyGen tidal energy project off the coast of Scotland has four turbines producing 1.5 megawatts each, enough electricity collectively to power up to 7,000 homes annually. On July 3, the Swedish company SKF announced that its bearings and seals on one of the turbines had passed the 6 1/2-year mark without needing unplanned or disruptive maintenance. It has been working closely with the industry for a decade on design and testing. Achieving six years in the water with constant operations is a 'very significant milestone' that bodes well for the future of tidal energy, said Rémi Gruet, CEO of Ocean Energy Europe. Scotland and the United Kingdom are global leaders in tidal energy. The MeyGen site, operated by SAE Renewables, has been sending electricity to the grid for about eight years. There are very few tidal energy projects generating electricity continuously. Most have been tests and demonstrations, said Andrea Copping, an expert in marine renewable energy development. Copping said there are still large hurdles to overcome before tidal energy can be adopted more widely, such as dealing with regulatory issues, potential environmental effects and conflicts with other ocean users. Still, the Scotland project seems to have addressed the question of whether the turbines can last in seawater, added Copping, a distinguished faculty fellow in the School of Marine and Environmental Affairs at the University of Washington. 'I think they have checked the boxes,' she said. 'Because skeptics, and that includes investors of course and governments, said, 'How on Earth are you going to operate these things especially for any length of time in this very tough environment?' And that's what I think they proved.' It's very hard to take what is essentially a wind turbine normally found on land and put it under water, said Fraser Johnson, operations and maintenance manager at MeyGen. The record-setting turbine should keep going for at least another year before it needs to come out of the water for maintenance, he added. The four turbines are in the Inner Sound of the Pentland Firth, a narrow channel between the Scottish mainland and Stroma Island known for strong tidal currents. Tidal energy systems need strong currents to make electricity efficiently. MeyGen plans to add 20 turbines in 2030 to produce more electricity, after needed upgrades to the electricity grid are finished. The site could eventually hold as many as 130 turbines that are more powerful than those at the site today. The MeyGen site is in the open water, while another type of tidal project involves creating a dam-like structure called a barrage across tidal waters. With four turbines, MeyGen is considered the largest tidal energy project of its kind worldwide, said Johnson. 'It's a title we wish we didn't have. We want more, we want others,' he said. 'Unfortunately others are having difficulty achieving what MeyGen has achieved. But working with SKF moving forward, we'll push the industry forward.' © Copyright 2025 The Associated Press.

Private lunar lander from Japan crashes into moon in failed mission
This image provided by ispace, inc. shows the Resilience lander circling the moon, June 4, 2025. (ispace, inc. via AP) A private lunar lander from Japan crashed while attempting a touchdown Friday, the latest casualty in the commercial rush to the moon. The Tokyo-based company ispace declared the mission a failure several hours after communication was lost with the lander. Flight controllers scrambled to gain contact but were met with only silence and said they were concluding the mission. Communications ceased less than two minutes before the spacecraft's scheduled landing on the moon with a mini rover. Until then, the descent from lunar orbit seemed to be going well. CEO and founder Takeshi Hakamada apologized to everyone who contributed to the mission, the second lunar strikeout for ispace. Two years ago, the company's first moonshot ended in a crash landing, giving rise to the name 'Resilience' for its successor lander. Resilience carried a rover with a shovel to gather lunar dirt as well as a Swedish artist's toy-size red house for placement on the moon's dusty surface. Company officials said it was too soon to know whether the same problem doomed both missions. 'This is the second time that we were not able to land. So we really have to take it very seriously,' Hakamada told reporters. He stressed that the company would press ahead with more lunar missions. A preliminary analysis indicates the laser system for measuring the altitude did not work as planned, and the lander descended too fast, officials said. 'Based on these circumstances, it is currently assumed that the lander likely performed a hard landing on the lunar surface,' the company said in a written statement. Long the province of governments, the moon became a target of private outfits in 2019, with more flops than wins along the way. Launched in January from Florida on a long, roundabout journey, Resilience entered lunar orbit last month. It shared a SpaceX ride with Firefly Aerospace's Blue Ghost, which reached the moon faster and became the first private entity to successfully land there in March. Another U.S. company, Intuitive Machines, arrived at the moon a few days after Firefly. But the tall, spindly lander face-planted in a crater near the moon's south pole and was declared dead within hours. Resilience was targeting the top of the moon, a less treacherous place than the shadowy bottom. The ispace team chose a flat area with few boulders in Mare Frigoris or Sea of Cold, a long and narrow region full of craters and ancient lava flows that stretches across the near side's northern tier. Plans had called for the 7.5-foot (2.3-meter) Resilience to beam back pictures within hours and for the lander to lower the piggybacking rover onto the lunar surface this weekend. Made of carbon fiber-reinforced plastic with four wheels, ispace's European-built rover — named Tenacious — sported a high-definition camera to scout out the area and a shovel to scoop up some lunar dirt for NASA. The rover, weighing just 11 pounds (5 kilograms), was going to stick close to the lander, going in circles at a speed of less than one inch (a couple centimeters) per second. It was capable of venturing up to two-thirds of a mile (1 kilometer) from the lander and should be operational throughout the two-week mission, the period of daylight. Besides science and tech experiments, there was an artistic touch. The rover held a tiny, Swedish-style red cottage with white trim and a green door, dubbed the Moonhouse by creator Mikael Genberg, for placement on the lunar surface. Minutes before the attempted landing, Hakamada assured everyone that ispace had learned from its first failed mission. 'Engineers did everything they possibly could' to ensure success this time, he said. He considered the latest moonshot 'merely a steppingstone' to its bigger lander launching by 2027 with NASA involvement. Ispace, like other businesses, does not have 'infinite funds' and cannot afford repeated failures, Jeremy Fix, chief engineer for ispace's U.S. subsidiary, said at a conference last month. While not divulging the cost of the current mission, company officials said it's less than the first one which exceeded $100 million. Two other U.S. companies are aiming for moon landings by year's end: Jeff Bezos' Blue Origin and Astrobotic Technology. Astrobotic's first lunar lander missed the moon altogether in 2024 and came crashing back through Earth's atmosphere. For decades, governments competed to get to the moon. Only five countries have pulled off successful robotic lunar landings: Russia, the U.S., China, India and Japan. Of those, only the U.S. has landed people on the moon: 12 NASA astronauts from 1969 through 1972. NASA expects to send four astronauts around the moon next year. That would be followed a year or more later by the first lunar landing by a crew in more than a half-century, with SpaceX's Starship providing the lift from lunar orbit all the way down to the surface. China also has moon landing plans for its own astronauts by 2030.

Private lunar lander from Japan falls silent while attempting moon touchdown
This image taken from video shows flight controllers at ispace Mission Control in Tokyo awaiting confirmation of their private lunar lander touching down on the moon on Friday. By Marcia Dunn A private lunar lander from Japan fell silent while descending to the moon with a mini rover on Friday and its fate was unknown. The Tokyo-based company ispace said its lander dropped out of lunar orbit as planned and everything seemed to be going well. But there was no immediate word on the outcome, following the hourlong descent. As the tension mounted, the company's livestream of the attempted landing came to an abrupt end. 'We haven't been able to confirm,' one of the commentators said in Japanese, but Mission Control 'will continuously attempt to communicate with the lander.' The encore came two years after the company's first moonshot ended in a crash landing, giving rise to the name Resilience for its successor lander. Resilience carried a rover with a shovel to gather lunar dirt as well as a Swedish artist's toy-size red house for placement on the moon's dusty surface.
