The Nevada-based company said it plans to ultimately ramp up to producing 100 gigawatt-hours annually of ultra-thin battery-grade materials from both new and recycled sources in the United States for the first time.” Redwood founder CEO JB Straubel, who previously worked at Tesla, said at an event announcing the loan that he had a “front row seat” while at the Elon Musk-helmed electric vehicle maker to “some of the bigger challenges the the entire industry would face as it scales,” particularly around the battery materials supply chain. “It was somewhat clear even way back then, eight years ago, that this would be a really big bottleneck for the entire industry as it scaled,” Straubel said….

Redwood plans to manufacture battery anodes, containing copper and graphite, and cathodes, containing all the critical metals in a battery — like lithium, nickel, and cobalt — amounting to nearly 80 percent of the materials cost of a lithium-ion battery.

A Detroit newspaper reports Ford will also announce plans Monday to help build a $2.5 billion electric-vehicle battery plant in Michigan.

In fact, this year in America some electric cars could become “as cheap as or cheaper than cars with internal combustion engines,” reports the New York Times — specifically because of “increased competition, government incentives and falling prices for lithium and other battery materials.”

By extending the batteries’ lives, project developers can save both resources and costs. Hall estimates that a system like B2U’s could lower grid-scale battery capital costs by about 40%. “Second life and re-use helps the overall lifecycle be more energy efficient, given all the efforts that go into making that battery,” Hall said in an interview. “So you’re getting maximum value out of it.” Batteries are worked hard during their years powering vehicles, and over time their range deteriorates. But they still hold value as stationary storage, which has gentler demands, Hall said. The batteries in the B2U system are up to 8-years old and once powered vehicles built by Honda and Nissan.

For Amazon, these natural gas fuel cells will be used as the primary energy supply, delivering 24.3 megawatts of power to each of the three datacenter sites. “We are investing in fuel cells as a way to power a small number of our operations in Oregon,” an Amazon spokesperson told The Register in an email. “We continually innovate to minimize our impact on our neighbors, local resources, and the environment and this technology provides a pathway for less carbon intensive solutions in the region.”

Continuing to use fossil fuels to power its datacenters is at odds with Amazon’s stated sustainability goals — which include transitioning facilities to 100 percent renewable energy by 2025. However, sources familiar with the matter tell The Register that Amazon’s decision to use natural gas fuel cells was made in part due to challenges associated with power transmission infrastructure in the region. Oregon Live notes that the e-tail giant has had problems with landowners, who have objected to having high-voltage transmission lines cross their properties. Fuel cells provide Amazon a way to circumvent these headaches by generating the power onsite. However, regulators are concerned that the decision could actually increase Amazon’s carbon footprint in the region as the power supplied by local utilities includes a mix of hydroelectric power. In documents filed with the state, it’s estimated the fuel cells would generate 250,000 metric tons of carbon dioxide annually.

The U.S. Energy Department said the newly approved design “equips the nation with a new clean power source to help drive down” planet-warming greenhouse gas emissions. It’s the seventh nuclear reactor design cleared for use in the United States. The rest are for traditional, large, light-water reactors. Diane Hughes, NuScale’s vice president of marketing and communications, said the design certification is a historic step forward toward a clean energy future and makes the company’s VOYGR power plant a near-term deployable solution for customers. The first small modular reactor design application package included over 2 million pages of supporting materials, Hughes added. “NuScale has also applied to the NRC for approval of a larger design, at 77 megawatts per module, and the agency is checking the application for completeness before starting a full review,” adds the report.

Two men were arrested on New Year’s Eve for allegedly shutting down four Washington state power substations in late December that led to power outages for thousands across Pierce County. Matthew Greenwood and Jeremy Crahan have been charged with conspiracy to damage energy facilities and Greenwood faces a separate charge of possessing illegal short-barreled rifles…. The two cut off power to thousands of locals and caused at least $3 million worth of damage, according to charging documents.

Investigators identified Greenwood and Crahan almost immediately after the attacks took place by using cell phone data that allegedly showed both men in the vicinity of all four substations, according to court documents. Surveillance images cited in the court documents also showed images of one of the men and of the getaway car….

The two face up to 20 years behind bars if convicted of conspiring to attack energy facilities.

In addition, possession of an unregistered firearm is punishable by up to ten years in prison, according to a statement from the Department of Justice. But identifying the suspects was apparently pretty simple.
“When law enforcement served a search warrant on the home of the suspects, they recovered distinctive clothing pictured in the surveillance photos.”

Currently, MagSafe is a proprietary standard from Apple, and even accessory manufacturers have to pay to use such a standard. While Apple can still technically limit some features to MagSafe certified accessories, the announcement of the Qi2 standard is good news to ensure that this type of accessory is compatible with different phones. The new Qi2 standard will replace its Qi predecessor once it becomes available. WPC says that one billion Qi devices are expected to be sold globally by 2023. The first Qi2 certified devices and accessories are expected to be introduced by the end of the year.

Additionally, the European Commission is “expected to consider outlawing the use of non-rechargeable portable batteries,” though this would likely come with many exceptions and wouldn’t happen before the end of the decade.

“Using only inexpensive raw materials, a team from Rice’s Laboratory for Nanophotonics, Syzygy Plasmonics Inc. and Princeton University’s Andlinger Center for Energy and the Environment created a scalable catalyst that needs only the power of light to convert ammonia into clean-burning hydrogen fuel….”

The research follows government and industry investment to create infrastructure and markets for carbon-free liquid ammonia fuel that will not contribute to greenhouse warming. Liquid ammonia is easy to transport and packs a lot of energy, with one nitrogen and three hydrogen atoms per molecule. The new catalyst breaks those molecules into hydrogen gas, a clean-burning fuel, and nitrogen gas, the largest component of Earth’s atmosphere. And unlike traditional catalysts, it doesn’t require heat. Instead, it harvests energy from light, either sunlight or energy-stingy LEDs….

“This discovery paves the way for sustainable, low-cost hydrogen that could be produced locally rather than in massive centralized plants,” said Peter Nordlander, also a Rice co-author.

Sometimes, it does so on the street, but more often, it happens when the owner is recharging the lithium ion battery. A mismatched charger won’t always turn off automatically when the battery’s fully charged, and keeps heating up. Or, the highly flammable electrolyte inside the battery’s cells leaks out of its casing and ignites, setting off a chain reaction.

“These bikes when they fail, they fail like a blowtorch,” said Dan Flynn, the chief fire marshal at the New York Fire Department. “We’ve seen incidents where people have described them as explosive — incidents where they actually have so much power, they’re actually blowing walls down in between rooms and apartments.”

And these fires are getting more frequent.

As of Friday, the FDNY investigated 174 battery fires, putting 2022 on track to double the number of fires that occurred last year (104) and quadruple the number from 2020 (44). So far this year, six people have died in e-bike-related fires and 93 people were injured, up from four deaths and 79 injuries last year.

BMW said it is partnering with Envision AESC on its plans for a dedicated battery plant in South Carolina. The Japan-based energy company will produce round lithium-ion battery cells specifically designed for BMW’s next-gen EV platform. When it’s completed, the battery factory will have an annual capacity of 30 gigawatt-hours (GWh). BMW has also announced plans to build EV production facilities in Europe and China to meet demand. The company currently has several electric models for sale, including the i4 sedan and iX SUV.
