The fourth quarter is past its midway point, and Tesla’s Megafactory in Lathrop, California, seems like it’s still going full speed ahead. During a recent drone flyover of the site, a fleet of 332 Megapack batteries was spotted in the facility’s staging areas.

The Tesla Megapack may not be as visually compelling as the Cybertruck or the Model 3 Highland, but it is a key product in Tesla’s portfolio. Designed for grid use, the Megapack has the potential to disrupt the energy sector. The battery has been performing well so far, as it has been deployed successfully in high-profile projects like the 182 MW/730 MWh battery farm in Moss Landing, California, and the 150 MW/300 MWh system in New South Wales, Australia.

The Megapack is available in two variants: a 2-hour version that offers 1.9 MW of power and 3.9 MWh of energy and a 4-hour variant that features 1 MW of power and 3.9 MWh of energy. The grid-scale battery is priced at $1,908,590 for the four-hour variant with installation and $2,123,590 for the two-hour variant with installation. Without installation charges, the Megapack is priced at $1,321,390 for the two-hour variant and $1,270,310 for the four-hour version.

The 100MW/200MWh Chinchilla battery in Queensland, Australia, has been registered and connected to the grid. Expectations are high that the massive battery farm’s commissioning will begin soon.

The Chinchilla battery features 80 Tesla Megapack batteries. It is also the first battery farm that will be built by state-owned generator CS Energy, as noted in a Renew Economy report. The facility was committed as part of the state’s response to an explosion at the Callide coal-fired generator — an incident that helped convince the state to accelerate its adoption of sustainable solutions.

The 80 Tesla Megapack batteries are situated next to the Kogan Creek coal-fired generator, which also happens to be owned by CS Energy. The 750MW Kogan Creek coal-fired generator is among the largest coal-fired facilities in Australia. As per local reports, CS Energy is looking to develop a clean energy hub around Kogan Creek, so the Tesla Megapack farm could be considered part of the state-owned generator’s initiatives in the area.

Vietnamese billionaire Pham Nhat Vuong wants to make VinFast Auto into a viable global electric vehicle brand. But its journey so far has been bumpy.

In its first 75 years, RAND helped shape how humankind thought about and used space for the benefit of humanity. And it intends to have a similar impact on the next 75 years of space sustainability, security, and governance. Researchers identified concepts worthy of future study.

Swedish battery maker Northvolt AB has developed its first sodium-ion product, a technology that could cut reliance on scarce raw materials and lay the foundation for the company’s next generation of electric-car batteries.

Various forms of heat pumps—refrigerators, air conditioners, heaters—are estimated to consume about 30 percent of the world’s electricity. And that number is almost certain to rise, as heat pumps play a very large role in efforts to electrify heating to reduce the use of fossil fuels.

Most existing versions of these systems rely on the compression of a class of chemicals called hydrofluorocarbons, gasses that were chosen because they have a far smaller impact on the ozone layer than earlier refrigerants. Unfortunately, they are also extremely potent greenhouse gasses, with a short-term impact several thousand times that of carbon dioxide.

Alternate technologies have been tested, but all of them have at least one major drawback in comparison to gas compression. In a paper released in today’s issue of Science, however, researchers describe progress on a form of heat pump that is built around a capacitor that changes temperature as it’s charged and discharged. Because the energy spent while charging it can be used on discharge, the system has the potential to be highly efficient.

To enhance their catalytic efficiency in degrading organic pollutants, such as RB and urea, researchers further functionalized the surface of the micromotors with laccase, the bio-catalytic counterpart, for the generation of ammonia from urea. Urea is an emerging contaminant, being a common pollutant from residential activities (urea is the main component of urine) and from different industrial processes.

The chemical component laccase accelerates the conversion of urea into ammonia upon contact with contaminated water. This ammonia can be transformed into hydrogen, which is a clean and sustainable energy source.

“This is an interesting discovery. Today, water treatment plants have trouble breaking down all the urea, which can result in eutrophication when the water is released. This is a serious problem in urban areas in particular,” says Rebeca Ferrer, a PhD student from Dr. Katherine Villa’s group at ICIQ.

Ocean Eye will illuminate the hidden realms of marine biodiversity and pave the way for unprecedented insights into the ocean using lidar technology and advanced sensors.

In a groundbreaking initiative, researchers from the Technical University of Denmark (DTU) and Aarhus University spearhead the Ocean Eye project. This revolutionary undertaking aims to transform our understanding of marine biodiversity using cutting-edge optical technologies, according to a university press release.

The project utilizes a combination of hyperspectral cameras, lasers, and artificial intelligence on an autonomous vessel to gather comprehensive data on coastal waters, surpassing the limitations of traditional methods.
