Korea Zinc buys wind and solar developer Epuron, delivering a wind and solar portfolio of up to 9GW for its green metals and hydrogen ambitions.

Korean Zinc, the world’s biggest zinc, lead and silver producer, has bought Australian-based renewable energy developer Epuron as part of its move towards 100 per cent renewables, green metals and green hydrogen.

The purchase is a significant move, and underlines the determination of some of the world’s biggest metals companies to switch to green products, in moves that will surely turbo-charge the development of wind and solar projects in Australia and across the globe.

PENA, the division of Panasonic which produces lithium-ion batteries at the Sparks Gigafactory, will move into an existing building at 645 E. Plumb Lane, about half a mile east of the Reno-Tahoe International Airport. PENA’s headquarters will move from the Gigafactory to the Plumb Lane campus.

“Our new facility in Reno underscores our commitment to evolving and growing to stay at the forefront of the mobility market,” Allan Swan, president of PENA, said in a news release. “Investing in innovation and workforce initiatives in the local community supports our mission of creating a future powered by sustainable energy.”

Australian researchers have struck a deal to commercialise a new next-generation graphene material they say could unlock cheaper and better performing lithium-ion batteries.

Researchers at the ARC Centre of Excellence for Electromaterials Science (ACES), based at the University of Wollongong, say they have discovered a new form of graphene, called ‘Edge Functionalised Graphene’ (EFG), which is both highly conductive and processable for use in a range of electronics.

This includes lithium-ion batteries, with the innovative graphene material promising to improve the efficiency and lower the cost of battery technology used in energy storage devices and electric vehicles.

Solar and wind resources are the lowest marginal cost sources of electricity in most of the world. Solar, wind, and other forms of green energy produce power as and when it’s available. And as the world starts to transition away from cheap, responsive, and heavily polluting energy sources like coal, the electric grid now faces a challenge: how to manage the multi-day variability of renewable energy, even in periods of multi-day weather events, without sacrificing energy reliability or affordability.

In 2017, Tesla built and installed the world’s largest lithium-ion battery at Hornsdale in South Australia, which was a huge success. But there are inherent issues with lithium batteries; they are expensive, better suited to quick turnaround than long-term storage.

However, Form Energy is focused on developing low-cost energy storage technology to enable a reliable, secure, and fully renewable electric grid year-round. The Massachusetts-based startup recently unveiled a new rechargeable iron-air battery capable of delivering electricity for 100 hours at system costs competitive with conventional power plants and at less than 1/10th the cost of lithium-ion.

Danish energy firm Orsted has announced that its Hornsea 2 offshore wind farm generated its first power, representing a significant milestone in the facility’s development.

When fully operational, Hornsea 2’s wind turbines will be capable of generating 1.32 GW of clean electricity – taking the title of ‘world’s largest operating offshore wind farm‘from its sibling project, Hornsea 1. Together, the two projects will be capable of providing enough power for well over 2.3 million homes.

Located 89 km off the UK’s east coast, the Hornsea 2 achieved its first power after its offshore substation (OSS), the world’s largest offshore AC substation, and reactive compensation station (RCS), were installed in late October 2021. Since that time, Ørsted and its partner companies have been working hard to commission and energize the wind farm in preparation for its anticipated operational date next year.

And it’s a hybrid mix of hydrogen and electric power.

Global mining company Anglo American is experimenting with hydrogen to power the giant mining trucks.

Mining trucks consume 35.3 gallons (134 liters) of diesel per hour with their enormous weight of around 220 metric tonnes and therefore emitting vast amounts of carbon dioxide into the atmosphere.

In order to reduce the mining industry’s carbon footprint, Anglo American is focused on mining trucks.

The company is collaborating with several partners, such as Engie, NPROXX, First Mode, Williams Advanced Engineering, Ballard, ABB, Nel, and Plug Power, to develop a hybrid mining vehicle, fueled with hydrogen and electricity.

Flying saucers are on their way to the Moon.

MIT scientists are developing a new concept for a circular hovering rover that levitates thanks to the moon’s natural electric field, a press statement reveals.

The new machines take advantage of the fact that airless bodies such as the moon and asteroids build up an electric field through direct exposure to the sun and their surrounding plasma. Such machines could be deployed on lucrative scouting missions on the surface of the moon as well as to nearby asteroids.

A new type of hovering spacecraft On a body as large as the moon, the surface charge is strong enough to power levitating machines — in fact, it has already been shown to levitate lunar dust up to a meter above the ground.

The many-worlds interpretation of quantum mechanics predicts the formation of distinct parallel worlds as a result of a quantum mechanical measurement. Communication among these parallel worlds would experimentally rule out alternatives to this interpretation. A procedure for “interworld’’ exchange of information and energy, using only state of the art quantum optical equipment, is described. A single ion is isolated from its environment in an ion trap. Then a quantum mechanical measurement with two discrete outcomes is performed on another system, resulting in the formation of two parallel worlds. Depending on the outcome of this measurement the ion is excited from only one of the parallel worlds before the ion decoheres through its interaction with the environment. A detection of this excitation in the other parallel world is direct evidence for the many-worlds interpretation.

Qubits are the basic building block of a quantum processor, and are so named because they represent a continuum of complex superpositions of two basic quantum states. The power of qubits comes in part from their ability to encode significantly more information than a classical bit — an infinite set of states between 0 and 1. In mathematical terms, quantum gates that manipulate the state of individual qubits are unitary operators drawn from SU.

Rigetti’s superconducting quantum processors are based on the transmon design [1]. Each physical qubit is an anharmonic oscillator, meaning that the energy gaps between subsequent qubit energy states decrease as the qubit climbs higher up the state ladder. We typically only address the first two states, 0 and 1 (in the literature, sometimes referred to as g(round) and e(xcited)); however, the design of our qubits supports even higher states. The simple structure of the transmon energy levels gives superconducting qubits the unique ability to address many of these states in a single circuit.
