They could store 15,000 times more energy than steel springs and three times more energy than lithium.
A group of researchers have carried out a techno-economic analysis of three revamping strategies for an operating photovoltaic power plant in southeast Spain. They found the highest production value by installed power is obtained when both the modules and inverters are replaced.
Grenergy, a Spanish independent power producer focused on the development of PV, wind, and energy storage projects, has announced the arrival of 105 BYD batteries at the port of Iquique, Chile.
Grenergy said that the Chipol Guangan cargo ship, arriving after a 42-day journey from Dachan, China, has delivered 1,050 MC Cube ESS battery modules with a total storage capacity of 600 MWh. The modules will support the Oasis de Atacama solar-plus-storage project in Chile.
Oil and gas giant bp spins offshore wind interests into JV with another fossil major, in what the CEO describes as a “capital-light” approach to “an electrifying world.”
Photonic space-time crystals enhance light interaction and amplification, offering new applications in optical information processing.
Photonic space-time crystals are advanced materials designed to enhance the performance and efficiency of technologies like wireless communication and lasers. These crystals have a unique structure that is periodically arranged in three spatial dimensions and also changes over time, allowing precise control of light’s behavior. Researchers from the Karlsruhe Institute of Technology (KIT), in collaboration with Aalto University, the University of Eastern Finland, and Harbin Engineering University in China, have demonstrated how these four-dimensional materials can be applied in real-world technologies. Their findings were published in Nature Photonics.

MIT engineers have discovered that the mobula ray, a type of filter-feeding aquatic ray, utilizes a unique mechanism to feed and breathe simultaneously, which could revolutionize industrial water filters.
By studying the geometry of the ray’s mouth and gill structures, they developed a blueprint for more efficient filtration systems, balancing permeability with selectivity to enhance performance without increasing energy consumption.

Li-ion batteries that last beyond the life cycle of the EV can be bundled into energy storage solution for renewable energy projects.
A team of engineers is reimagining one of the essential processes in modern manufacturing. Their goal? To transform how a chemical called acrylonitrile (ACN) is made—not by building world-scale manufacturing sites, but by using smaller-scale, modular reactors that can work if they let the catalyst, in a sense, “breathe.”
Their article, titled “Propene Ammoxidation over an Industrial Bismuth Molybdate-Based Catalyst Using Forced Dynamic Operation,” is published in Applied Catalysis A: General.
ACN is everywhere, from carbon fibers in sports equipment to acrylics in car parts and textiles. Traditionally, producing it requires a continuous, energy-intensive process. But now, researchers at the University of Virginia and the University of Houston have shown that by pausing to “inhale” fresh oxygen, a chemical catalyst can produce ACN more efficiently. This discovery could open the door to smaller, versatile production facilities that adapt to fluctuating needs.
The FCC has opened up the entire 6 GHz band for very low-power (VLP) devices and here’s how it will affect your next gadget.
Dyson spheres and rings have always held a special fascination for me. The concept is simple: build a great big structure either as a sphere or ring to harness the energy from a star. Dyson rings are far more simple and feasible to construct and in a recent paper a team of scientists explore how we might detect them by analyzing the light from distant stars. The team suggests they might be able to detect Dyson rings around pulsars using their new technique.
Like their spherical cousins, Dyson rings remain for now, a popular idea in science fiction yet they are starting to appear more and more in scientific debates. The concept of the ring is similar to the sphere, a megastructure designed to encircle a star, harnessing its energy on a gargantuan scale.
It might consist of a series of satellites or even habitats in a circular orbit with solar collectors and unlike the spheres, require far less resources to build. The concept of the sphere was first proposed by physicist and mathematician Freeman Dyson in 1960. Such structures might be detectable and reveal the existence of intelligent civilizations.
