Indonesia holds the world’s largest reserves of nickel, conferring strategic importance on the world’s fourth-most-populous country as a supplier of raw materials for the batteries required by the global energy transition.

The Indonesia Weda Bay Industrial Park (IWIP) is one of the world’s largest nickel processing facilities (the main concession in Weda district that feeds this smelting complex is the world’s single largest nickel mine).

UNSW researchers were able to recover silicon from end of life solar PV panels pure enough for re-use in silicon carbide-based devices. Their novel multi-step method which includes thermal and chemical processes, also recovers silver.

The study:Microrecycling of waste solar cells via an in-situ fluorine-generating thermal treatment for high purity silicon recovery

Note: Can anyone tell what are the effects of these chemical processes to the environment / living beings?

Extreme heatwaves in the world’s three largest electricity markets – China, the US and India, had a measurable impact on electricity demand, contributing to a surge in fossil generation.

Ember has developed a methodology to estimate the global impact of high temperature on electricity demand. The present report zooms in on the role of air cooling in the three largest power markets – China, the US and India – though the implications are worldwide.

Proxima Fusion, a European fusion energy startup, has introduced Stellaris, which the company said is the world’s first integrated concept for a commercial fusion power plant designed for continuous, reliable operation. Published in Fusion Engineering and Design, it uses advanced computational optimization, high-temperature superconducting (HTS) magnets and quasi-isodynamic (QI) stellarator technology to bring fusion energy near to commercialization, the company said.

Stellaris builds on the results of the Wendelstein 7-X (W7-X) research experiment in Germany, the most advanced QI stellarator prototype in the world, directed by the Max Planck Institute for Plasma Physics and the product of over €1.3 billion (about $1.4 billion) in funding from the German Federal Government and the European Union.

With Alpha, its prototype stellarator, Proxima Fusion is poised to show net fusion energy by 2031. In an interview with EE Times, Proxima Fusion CEO Francesco Sciortino remarked a clear road towards fusion on the grid over the next decade, addressing European energy security and worldwide energy needs.

Commissioned to create a family residence in an area known for its cold, snowy winters and hot summers, Florian Busch Architects has completed the House W. Taking the form of a timber barn-inspired structure that's partially covered in solar panels, the home's energy efficient design allows it to harness almost twice as much power as it requires annually.

House W is located in Nakafurano, Hokkaido, Japan. The home is situated on the site of an old farmer's barn and is surrounded rice paddies and asparagus fields, so draws inspiration from this setting.

The exterior is part-finished in a solar skin that allows it to run off-the-grid (together with a battery array). A studio representative told us that there are 56 panels installed, resulting in a total capacity of 23 kW. This is combined with a heat pump that's connected to a nearby water source and offers a relatively constant temperature throughout the year, allowing it to run the underfloor heating as well as producing warm water for the house.

We've no figures on the home's actual power usage, but Florian Busch Architects says the solar panels provide almost twice as much as its requirements, annually.

This is a great episode about geothermal, very technical and practical. I'm curious about the fracking side of it - this has been controversial in traditional oil fracking, not only because of the fossil fuel side of it but also the effect it has on nature.

What do you think? Is it a necessary evil if (as they say) it would provide enough energy to last until the heat death of the universe?

A Michigan nuclear plant is looking to make history not once but twice over: First by restarting a reactor shuttered in 2022 and second with newly solidified plans to build the nation’s first small modular reactors.

Holtec International — the nuclear company best known for decommissioning shuttered plants and manufacturing the canisters that store spent fuel — bought the Palisades nuclear plant on the southeastern shore of Lake Michigan a month after utility giant Entergy took the financially troubled single-reactor facility offline.

Last year, the Department of Energy’s Loan Programs Office finalized a deal to give Holtec $1.52 billion to bring the 55-year-old, 800-megawatt pressurized water reactor back online. The company wants to plug the facility back into the grid by the end of this year.

Now Holtec plans to nearly double the electricity output from Palisades by building two of its own small modular reactors, or SMRs, at the site.

On Tuesday, top executives gathered at the facility in Covert Township, Michigan, to unveil blueprints for adding a pair of its proprietary SMR-300s and announce Hyundai Engineering and Construction Co. — the South Korean firm already working with the Florida-based Holtec to develop its 300-MW units internationally — as its partner in the debut U.S. project. Completing the reactor would be a first not just for the country but the company. While Holtec has disassembled reactors, it has yet to build one, much less its own design.

“If we can’t do it, I don’t know who else is going to do it,” Rick Springman, the president of Holtec’s Global Clean Energy Opportunities division, told Canary Media ahead of the event. ​“I really think we can be the horse America can ride to a clean-energy future and to enable AI and everything else we want to do in this global competition.”

First, Holtec will need the Nuclear Regulatory Commission’s approval of its reactor design.

So far, the U.S. federal regulator has only approved one SMR, Oregon-based NuScale Power’s 50 MW unit. The first plant designed around NuScale’s reactors, a 720 MW station built on property owned by the Idaho National Laboratory to provide power to ratepayers in Utah, was scrapped in November 2023 amid rising costs.

2024 marked a breakout year for nuclear power in the U.S., as Congress passed new legislation to streamline reactor regulations, Microsoft put up $16 billion to reopen the mothballed unit at Pennsylvania’s Three Mile Island, and SMR developers lined up major deals with Amazon and Google.

Yet no SMR developer got the green light from the NRC to become the nation’s second certified design.

“Most of our competitors are essentially offering the technology but don’t want to take any risk,” Springman said.

In other words, those developers will design and license the technology and make money off the intellectual property, he said, but utilities and construction firms must provide the financing, time, and materials.

“You have this stagnation where no one wants to stand behind the project,” Springman said. ​“Enter Holtec. We can manufacture the parts, build the plant, and arrange the financing for the project. We can also manage the spent fuel … and we can decommission the plant at end of life. We can do the entire spectrum of the project. There’s no U.S. company that can offer all of that.”
