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.

Cameco will own 49% of Westinghouse, while Brookfield Renewable and its institutional partners will own the rest. Westinghouse was acquired from Toshiba by Brookfield Business Partners , an affiliate of Canadian asset manager Brookfield, out of bankruptcy in 2018, for $4.6 billion, including debt. Brookfield Business said in a separate statement it expects to generate about $1.8 billion in proceeds from the sale of its 44% stake in Westinghouse, with the balance distributed among institutional partners. The deal is expected to close in the second half of 2023. Brookfield Renewable and its partners will pay about $2.3 billion for the deal, whereas Cameco will incur equity costs of about $2.2 billion. Westinghouse’s existing debt structure will remain in place.

“Do not fall victim to online fraudsters or unauthorized dealers or manufacturers.”

Counterfeit batteries do not go through the same standardized testing as original equipment manufacturer batteries and can adversely impact the safety and health of the consumer….

Avoid aftermarket batteries when possible because they may be dangerous…. Consumers should avoid all third-party purchases of batteries, as they can appear to be legitimate OEM batteries but are likely counterfeit…. [B]atteries sold at deep discounts or at significantly lower-than-average prices are likely counterfeit.
The FBI warns you should always avoid batteries that:

are not properly packaged;
have misprinted or misspelled labels;
have labels that peel off; or
do not have official manufacturer batch numbers.

“The FBI’s warning is not specific to laptops or smartphones,” notes ZDNet, “which makes sense given that batteries are now found in everything from cars, scooters, e-bikes, e-cigarettes and trains to drones and more.”
