Hierarchical Li electrochemistry using alloy-type anode for high-energy-density Li metal batteries

Posted by in categories: chemistry, energy

Utilizing an ultra-thin Li anode with a thickness below 50 μm is crucial for enhancing the energy density of batteries. Here, the authors develop a finely tunable, thin alloy-based Li anode that features a hierarchical Li electrochemistry, enabling stable cycling and superior energy density in Li metal batteries.

Earth Has Received Power Beamed From A Satellite In Space For The First Time

Posted by in category: energy

This may have posted but it’s interesting as a start. Beaming energy from space to the ground is a great idea. One thing I always need is energy.

The experimental system could be used to send energy anywhere on Earth.

The Hottest Catalog of the Year: Comprehensive List of Slow-building Solar Flares

Posted by in categories: energy, satellites

Although solar flares have been classified based on the amount of energy they emit at their peak, there has not been significant study into differentiating flares since slow-building flares were first discovered in the 1980s. Scientists have now shown that there is a significant amount of slower-type flares worthy of further investigation.

Solar flares occur when magnetic energy builds up in the Sun’s atmosphere and is released as electromagnetic radiation. Lasting anywhere from a few minutes to a few hours, flares usually reach temperatures around 10 million degrees Kelvin. Because of their intense electromagnetic energy, solar flares can cause disruptions in radio communications, Earth-orbiting satellites and even result in blackouts.

The width-to-decay ratio of a flare is the time it takes to reach maximum intensity to the time it takes to dissipate its energy.

LG Chem is building a $3B EV battery cathode factory — the largest in the US [Update]

Posted by in categories: energy, materials

LG Chem is building a $3 billion battery cathode factory for EVs in Tennessee – and it just inked a multi-billion dollar deal with GM.

LG Chem has secured a long-term cathode material supply contract with General Motors (GM) worth $19 billion. The contract will commence in 2026 – when the factory is expected to come online – and run until 2035.

Ultium Cells, a joint venture between LG Energy Solution and GM, will primarily use the NCMA (nickel, cobalt, manganese, aluminum) cathode materials made at LG’s Tennessee factory.

Hydrogen container ship could slash carbon emissions by 3000 tons

Posted by in categories: energy, transportation

The H2 Barge 2 is a hydrogen fuel-cell powered ship designed to transport containers on the Rhine between Rotterdam (NL) and Duisburg (DE) with zero emissions that could represent a massive reduction in carbon emissions.

Developed by Dutch shipowner Future Proof Shipping (FPS) and funded by the EU Flagships project and the Interreg ZEM Ports NS project, the H2 Barge 2 (formerly Fenny 1 and FPS Waal) was built as a conventionally powered containership before being converted to electric drive – with the 1.2 MW of power to drive the vessel’s motors coming from six PEM fuel cells, hydrogen storage, and a number of battery packs placed below deck.

Compared to its previous incarnations, the H2 Barge 2 is expected to reduce 3,000 tons of CO2 annually while sailing a comparable amount of shipping containers up and down the Rhine. And, in doing so (the company says), the vessel proves that the European river fleet can be, “fully zero emission already today.”

This chart shows why heat pumps are still hot in the US

Posted by in category: energy

Sales slowed in 2023, but heat pumps are gaining ground on fossil fuels.

Heat pumps are still a hot technology, though sales in the US, one of the world’s largest markets, fell in 2023.

Redefining Helmet Safety: Scientists Develop New Material That Absorbs Six Times More Energy

Posted by in categories: energy, materials

Football players (and anyone else who takes hard hits) may want to breathe a sigh of relief.

In recent research, engineers at the University of Colorado of Boulder and Sandia National Laboratories have developed a new design for padding that can withstand big impacts. The team’s innovations, which can be printed on commercially available 3D printers, could one day wind up in everything from shipping crates to football pads—anything that helps to protect fragile objects, or bodies, from the bumps of life.

Scientists develop new molecular system made from abundant element manganese for photooxidation

Posted by in categories: chemistry, energy

Highly reducing or oxidizing photocatalysts are a fundamental challenge in photochemistry. Only a few transition metal complexes with Earth-abundant metal ions have so far advanced to excited state oxidants, including chromium, iron, and cobalt. All these photocatalysts require high energy light for excitation and their oxidizing power has not yet been fully exploited. Furthermore, precious and hence expensive metals are the decisive ingredients in most cases.

A team of researchers headed by Professor Katja Heinze of Johannes Gutenberg University Mainz (JGU) has now developed a new molecular system based on the element manganese. Manganese, as opposed to , is the third most abundant metal after iron and titanium and hence widely available and very cheap. The study is published in the journal Nature Chemistry.

Magnitude 5.7 earthquake hits Mauna Loa volcano on Hawaii’s Big Island

Posted by in category: energy

A magnitude 5.7 earthquake struck the world’s largest active volcano on Friday — Mauna Loa on the Big Island of Hawaii — knocking items off shelves and cutting power in a nearby town but not immediately prompting reports of serious damage.

The earthquake, which didn’t cause a tsunami and which the U.S. Geological Survey initially reported as magnitude 6.3, was centered on Mauna Loa’s southern flank at a depth of 23 miles, 1.3 miles southwest of Pahala.
