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.

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.”

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.

The team described the technology in a paper recently published in the journal Advanced Materials Technologies.

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.

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.

From the article: As much as 55,000 tons (50,000 metric tons) of hydrogen could lurk in the reservoir beneath the mine — enough to sustain the high flow rate for 238 years, according to the study.

A portion of ancient oceanic crust that sits atop Albania and hosts one of the largest chromium mines on Earth also contains a huge hydrogen reservoir, offering a potential source of clean energy.
