  • US hikes tariffs on imports of Chinese solar wafers, polysilicon and tungsten products

    US hikes tariffs on imports of Chinese solar wafers, polysilicon and tungsten products

    BANGKOK — The Biden administration plans to raise tariffs on solar wafers, polysilicon and some tungsten products from China to protect U.S. clean energy businesses.

    The notice from the U.S. Trade Representative’s office said tariffs on Chinese-made solar wafers and polysilicon will rise to 50% and duties on certain tungsten products will increase to 25%, effective on Jan. 1, following a review of Chinese trade practices.

    “The tariff increases announced today will further blunt the harmful policies and practices by the People’s Republic of China,” USTR Katharine Tai said in a statement. “These actions will complement the domestic investments made under the Biden-Harris Administration to promote a clean energy economy, while increasing the resilience of critical supply chains.”

    Last week, Washington tightened restrictions on Chinese access to advanced semiconductor technology. Beijing responded by banning exports to the U.S. of certain critical minerals needed to make computer chips, such as gallium, germanium and antimony. It also stepped up its controls on graphite exports to the U.S.

    China provides a very large share of most of those materials and the United States has been working to secure alternative sources in Africa and other parts of the world.

    Tungsten is another strategically vital metal whose production is dominated by China. The U.S. does not produce it. It’s used to make armaments and is also used in x-ray tubes and light bulb filaments, among other industrial applications.

    After Beijing announced its ban on exporting gallium and the other materials to the United States, analysts said tungsten was another likely area where China might strike back.

    Trade frictions have been escalating ahead of the inauguration of President-elect Donald Trump, who has voewed to impose 60% tariffs on Chinese goods, among other threats. President Joe Biden has said Trump’s promise of broad tariffs on foreign imports would be a mistake.

    His administration has kept in place tariffs that Trump imposed during his first term in office, in some cases raising them further, but says it has a more targetted approach.

    The investigation that led the USTR to raise the tariffs on solar panels concluded with a report in May that has prompted increases in tariffs on a range of products including electric vehicles, syringes and needles, medical gloves and facemasks, semiconductors and steel and aluminum products, among others.

  • European satellites launched to create artificial solar eclipses in a tech demo

    European satellites launched to create artificial solar eclipses in a tech demo

    CAPE CANAVERAL, Fla. — A pair of European satellites rocketed into orbit Thursday on the first mission to create artificial solar eclipses through fancy formation flying in space.

    Each fake eclipse should last six hours once operations begin next year. That’s considerably longer than the few minutes of totality offered by a natural eclipse here on Earth, allowing for prolonged study of the sun’s corona, or outer atmosphere.

    The launch took place from India.

    Billed as a tech demo, the two satellites will separate in a month or so and fly 492 feet (150 meters) apart once reaching their destination high above Earth, lining up with the sun so that one spacecraft casts a shadow on the other.

    This will require extreme precision, within just one millimeter, equivalent to a fingernail’s thickness, according to the European Space Agency. To maintain their position, the satellites will rely on GPS, star trackers, lasers and radio links, flying autonomously.

    Each cube-shaped spacecraft is less than 5 feet (1.5 meters) across. The shadow-casting satellite holds a disk to block the sun from the telescope on the other satellite. This disk will mimic the moon in a natural total solar eclipse, with the darkened satellite posing as Earth.

    “This has a huge scientific relevance” in addition to testing high-precision formation flying,” said the European Space Agency’s technology and engineering director Dietmar Pilz.

    Scientists need the glaring face of the sun completely blocked in order to scrutinize the wispy crown-like corona encircling it, getting an especially good look close to the solar rim on this mission. They’re particularly interested to learn why the corona is hotter than the surface of the sun, and also want to better understand coronal mass ejections, eruptions of billions of tons of plasma with magnetic fields out into space.

    The resulting geomagnetic storms can disrupt power and communication on Earth and in orbit. Such outbursts can also produce stunning auroras in unexpected places.

    With a lopsided orbit stretching from 370 miles (600 kilometers) to 37,000 miles (60,000 kilometers) away, the satellites will take nearly 20 hours to circle the world. Six of those hours — at the farther end of the orbit — will be spent generating an eclipse. The first results should be available in March, following checkout of both craft, according to the space agency.

    The $210 million mission, dubbed Proba-3, is expected to create hundreds of eclipses during its two-year operation. Once their job is done, both satellites will gradually drop lower until they burn up in the atmosphere, likely within five years.

    Liftoff was delayed a day by a last-minute issue with the backup propulsion system of one of the satellites, crucial for precision formation flying. The European Space Agency said engineers relied on a computer software fix.

  • Volunteers bring solar power to Hurricane Helene’s disaster zone

    Volunteers bring solar power to Hurricane Helene’s disaster zone

    BAKERSVILLE, N.C. — Nearly two weeks after Hurricane Helene downed power lines and washed out roads all over North Carolina’s mountains, the constant din of a gas-powered generator is getting to be too much for Bobby Renfro.

    It’s difficult to hear the nurses, neighbors and volunteers flowing through the community resource hub he has set up in a former church for his neighbors in Tipton Hill, a crossroads in the Pisgah National Forest north of Asheville. Much worse is the cost: he spent $1,200 to buy it and thousands more on fuel that volunteers drive in from Tennessee.

    Turning off their only power source isn’t an option. This generator runs a refrigerator holding insulin for neighbors with diabetes and powers the oxygen machines and nebulizers some of them need to breathe.

    The retired railroad worker worries that outsiders don’t understand how desperate they are, marooned without power on hilltops and down in “hollers.”

    “We have no resources for nothing,” Renfro said. “It’s going to be a long ordeal.”

    More than 43,000 of the 1.5 million customers who lost power in western North Carolina still lacked electricity on Friday, according to Poweroutage.us. Without it, they can’t keep medicines cold or power medical equipment or pump well water. They can’t recharge their phones or apply for federal disaster aid.

    Crews from all over the country and even Canada are helping Duke Energy and local electric cooperatives with repairs, but it’s slow going in the dense mountain forests, where some roads and bridges are completely washed away.

    “The crews aren’t doing what they typically do, which is a repair effort. They’re rebuilding from the ground up,” said Kristie Aldridge, vice president of communications at North Carolina Electric Cooperatives.

    Residents who can get their hands on gas and diesel-powered generators are depending on them, but that is not easy. Fuel is expensive and can be a long drive away. Generator fumes pollute and can be deadly. Small home generators are designed to run for hours or days, not weeks and months.

    Now, more help is arriving. Renfro received a new power source this week, one that will be cleaner, quieter and free to operate. Volunteers with the nonprofit Footprint Project and a local solar installation company delivered a solar generator with six 245-watt solar panels, a 24-volt battery and an AC power inverter. The panels now rest on a grassy hill outside the community building.

    Renfro hopes his community can draw some comfort and security, “seeing and knowing that they have a little electricity.”

    The Footprint Project is scaling up its response to this disaster with sustainable mobile infrastructure. It has deployed dozens of larger solar microgrids, solar generators and machines that can pull water from the air to 33 sites so far, along with dozens of smaller portable batteries.

    With donations from solar equipment and installation companies as well as equipment purchased through donated funds, the nonprofit is sourcing hundreds more small batteries and dozens of other larger systems and even industrial-scale solar generators known as “Dragon Wings.”

    Will Heegaard and Jamie Swezey are the husband-and-wife team behind Project Footprint. Heegaard founded it in 2018 in New Orleans with a mission of reducing the greenhouse gas emissions of emergency responses. Helene’s destruction is so catastrophic, however, that Swezey said this work is more about supplementing generators than replacing them.

    “I’ve never seen anything like this,” Swezey said as she stared at a whiteboard with scribbled lists of requests, volunteers and equipment. “It’s all hands on deck with whatever you can use to power whatever you need to power.”

    Down near the interstate in Mars Hill, a warehouse owner let Swezey and Heegaard set up operations and sleep inside. They rise each morning triaging emails and texts from all over the region. Requests for equipment range from individuals needing to power a home oxygen machine to makeshift clinics and community hubs distributing supplies.

    Local volunteers help. Hayden Wilson and Henry Kovacs, glassblowers from Asheville, arrived in a pickup truck and trailer to make deliveries this week. Two installers from the Asheville-based solar company Sundance Power Systems followed in a van.

    It took them more than an hour on winding roads to reach Bakersville, where the community hub Julie Wiggins runs in her driveway supports about 30 nearby families. It took many of her neighbors days to reach her, cutting their way out through fallen trees. Some were so desperate, they stuck their insulin in the creek to keep it cold.

    Panels and a battery from Footprint Project now power her small fridge, a water pump and a Starlink communications system she set up. “This is a game changer,” Wiggins said.

    The volunteers then drove to Renfro’s hub in Tipton Hill before their last stop at a Bakersville church that has been running two generators. Other places are much harder to reach. Heegaard and Swezey even tried to figure out how many portable batteries a mule could carry up a mountain and have arranged for some to be lowered by helicopters.

    They know the stakes are high after Heegaard volunteered in Puerto Rico, where Hurricane Maria’s death toll rose to 3,000 as some mountain communities went without power for 11 months. Duke Energy crews also restored infrastructure in Puerto Rico and are using tactics learned there, like using helicopters to drop in new electric poles, utility spokesman Bill Norton said.

    The hardest customers to help could be people whose homes and businesses are too damaged to connect, and they are why the Footprint Project will stay in the area for as long as they are needed, Swezey said.

    “We know there are people who will need help long after the power comes back,” she said.
