This marks the first time simulations have successfully identified the optimal balance between power output and structural strength in BWTs. These bladeless systems, still in the early stages of development, may soon progress from small-scale trials to grid-level electricity generation.

In a refreshing twist on the typical space race, the Faroe Islands Space Program isn’t about launching rockets—it’s about staying grounded and turning the Moon’s gravitational pull into clean, renewable energy. This ambitious initiative centers around Luna 12, an underwater tidal kite designed to convert ocean currents into electricity, offering a reliable energy source for the remote North Atlantic archipelago.

The program is a collaboration between Swedish industrial giant SKF, marine energy innovator Minesto, and the local Faroese utility Sev. Together, they aim to help the Faroe Islands reach their goal of 100% renewable energy by 2030—and they’re doing it without leaving the planet.

A groundbreaking new technology known as thermal energy storage (TES) is set to transform the future of energy storage. At the heart of this innovation is an advanced thermal emitter that captures heat and converts it into electromagnetic radiation, which is then transformed into electricity through photovoltaic cells. Compared to conventional batteries, this system offers a more scalable and sustainable alternative. If successful, it could pave the way for a more efficient and eco-friendly energy storage solution, potentially replacing existing, less reliable systems.

Renewable energy sources such as solar and wind power hold great promise for reducing our reliance on fossil fuels, but they come with one major obstacle: intermittency. Since these energy sources depend on weather conditions and time of day, their availability is often unpredictable. This unpredictability can lead to instability in power generation, creating challenges for managing electrical grids. To address these fluctuations, large-scale energy storage systems are essential to balance supply and demand.

A new sensor technology developed by Professor Thomas Anthopoulos from the University of Manchester, in collaboration with King Abdullah University of Science and Technology (KAUST), has made significant strides in addressing one of the key challenges to hydrogen adoption as an energy carrier. Published in Nature Electronics, this innovative sensor promises to revolutionize hydrogen safety across industries, homes, and transportation.

Hydrogen, while promising as a clean energy source, presents unique safety challenges. It is colorless, odorless, and highly flammable, making it difficult to detect using human senses. Efficient and reliable hydrogen detection systems are crucial for implementing hydrogen technologies safely, particularly as the world looks to transition away from fossil fuels.

Japan’s renewable energy ambitions have taken a significant step forward with the successful deployment of the AR1100 tidal turbine by Proteus Marine Renewables. Situated in the Naru Strait, between the Goto Islands in Nagasaki Prefecture, this milestone installation marks Japan’s first megawatt-scale grid-connected tidal energy system.

The AR1100 turbine, with a capacity of 1.1 MW, has the potential to play a key role in decarbonizing the Goto Islands’ power grid, helping Japan reduce its reliance on fossil fuels. “Our next immediate focus is the commissioning of the turbine, Japan’s first-ever MW-scale grid-connected tidal system, followed by the testing and accreditation phase,” said Philip Archer, Managing Director of Proteus Operations Japan.

A groundbreaking discovery by scientists at the Massachusetts Institute of Technology (MIT) could revolutionize clean energy production using materials as simple as old soda cans and seawater. By harnessing the power of aluminum and seawater to generate hydrogen fuel, this innovative approach could have far-reaching implications for sustainable energy systems, especially in maritime applications.

Aluminum, a material most commonly found in soda cans and foil wraps, is often overlooked for its potential in energy production. However, when treated correctly, aluminum can react with water to produce hydrogen gas—a clean, efficient fuel that only releases water vapor when burned. Although the basic chemical reaction between aluminum and water has been known for some time, scaling it up for practical and cost-effective use has been a significant challenge—until now.

A groundbreaking new study has revealed a potentially game-changing discovery beneath the Earth’s surface—a massive, untapped reservoir of hydrogen that could revolutionize the global energy landscape. According to scientists, approximately 6.2 trillion tons of hydrogen are stored in rocks and underground reservoirs, a quantity far exceeding the size of known oil reserves by a factor of 261. This remarkable find could offer a sustainable solution to the world’s energy needs and play a crucial role in combating climate change.

The research, led by Geoffrey Ellis, a petroleum geochemist at the U.S. Geological Survey (USGS), was published in the journal Science Advances. The study estimates that just a small fraction of this underground hydrogen could have profound implications for the global energy future. According to Ellis, extracting merely 2% of this hydrogen—equivalent to 124 billion tons—could supply all the hydrogen needed for net-zero carbon goals for centuries. This amount contains nearly twice the energy stored in all the known natural gas reserves on Earth.

Focused Energy, a German-American energy company, is on a mission to revolutionize the clean energy landscape with its groundbreaking laser fusion technology. Based in the Bay Area, with roots tracing back to Austin, Texas, Focused Energy has unveiled plans to build a cutting-edge $65 million facility dedicated to creating lasers capable of reaching temperatures as hot as the sun. These lasers will be harnessed to generate clean, sustainable power for homes across the United States.

Focused Energy is among a select group of companies working on laser fusion, an advanced form of nuclear fusion. For decades, scientists have dreamed of unlocking the power of fusion energy, often referring to it as the “holy grail” of clean energy. Unlike nuclear fission, which produces harmful radioactive waste, fusion has the potential to provide virtually limitless, clean, and renewable energy.

As renewable energy solutions continue to gain traction, wind power is emerging as a key player in the residential market, rivaling the popularity of solar energy. Meet the Liam F1 Mini Urban Wind Turbine by Archimedes – a compact and innovative wind turbine specifically designed for urban and suburban environments. This sleek, efficient turbine is set to change the way city dwellers harness clean energy, offering up to 1,500 kWh of free electricity per year, all while remaining virtually silent.

One of the standout features of the Liam F1 is its near-silent operation, a crucial benefit in noise-sensitive urban areas. While traditional wind turbines are known for their noise, which can be disruptive to nearby residents, the Liam F1 operates quietly thanks to its unique conical design. This makes it an ideal solution for densely populated cities where noise pollution is a major concern.

The Princeton Plasma Physics Laboratory (PPPL) has achieved a groundbreaking feat: creating a compact fusion reactor using 3D-printed parts and off-the-shelf materials, all small enough to fit on a kitchen table. This deceptively simple device—a glass vacuum tube surrounded by 3D-printed nylon and thousands of magnets—contains the key to replicating the power of the stars, potentially leading to a future of abundant, clean energy.

The story, shared by IEEE Spectrum, highlights how PPPL’s reactor could change the fusion landscape. While fusion reactors have existed for years, they’re typically massive and costly. Germany’s Wendelstein 7-X, an experimental stellarator, took two decades and $1.1 billion to build. In contrast, PPPL’s smaller-scale reactor prototype is an affordable proof of concept, demonstrating that the principles of fusion can be achieved with minimal resources and compact designs.
