While obtaining H2 from water splitting offers a promising strategy for renewable fuel production, current technologies rely on liquid freshwater. Here, authors use a hygroscopic electrolyte to achieve electrocatalytic water vapor splitting driven by renewable resources without liquid water.

Iceland will tunnel into a volcano to tap into virtually unlimited geothermal power
Posted by Michael LaTorra in category: energy
An initiative that sounds a lot like Jules Verne’s Journey to the Center of the Earth might mark the first time humans have tapped into magma, the molten rock liquid flowing beneath Earth’s crust. In 2026, Iceland’s Krafla Magma Testbed (KMT) project will drill into a volcano’s magma chamber, seeking to tap into its super-hot fumes to generate geothermal energy at a scale that has never been attempted before.
The endeavor promises to power homes across Iceland with a renewable, limitless energy source. And no, this won’t cause the currently active Krafla volcano to erupt, according to John Eichelberger, a volcanologist at the University of Alaska Fairbanks interviewed by New Scientist.
Geothermal energy, a technology harnessed by Iceland for years, involves drilling into hot underground regions to produce steam from heated water. This steam drives turbines, generating electricity. Today, at least 90% of all homes in Iceland are heated with geothermal energy and 70% of all energy used in the island nation comes from geothermal sources.

The sun is super active right now. Here’s how it can affect electronics on Earth
Posted by Genevieve Klien in categories: energy, space
To most people, the sun is a steady, never-changing source of heat and light. But to scientists, it’s a dynamic star, constantly in flux, sending energy out into space. Experts say the sun is now in its most active period in two decades, causing potential disruptions to radio and satellite communications. John Yang speaks with Bill Murtagh of NOAA’s Space Weather Prediction Center to learn more.

A hybrid supercomputer: Researchers integrate a quantum computer into a high-performance computing environment
Posted by Shubham Ghosh Roy in categories: chemistry, energy, quantum physics, supercomputing
Working together, the University of Innsbruck and the spin-off AQT have integrated a quantum computer into a high-performance computing (HPC) environment for the first time in Austria. This hybrid infrastructure of supercomputer and quantum computer can now be used to solve complex problems in various fields such as chemistry, materials science or optimization.
Demand for computing power is constantly increasing and the consumption of resources to support these calculations is growing. Processor clock speeds in conventional computers, typically a few GHz, appear to have reached their limit.
Performance improvements over the last 10 years have focused primarily on the parallelization of tasks using multi-core systems, which are operated in HPC centers as fast networked multi-node computing clusters. However, computing power only increases approximately linearly with the number of nodes.

Physicists uncover key to resolving long-standing inertial confinement fusion hohlraum drive deficit
Posted by Shailesh Prasad in categories: energy, physics
“Significant effort has been invested over the years to pinpoint the physical cause of the radiation drive-deficit problem,” Chen said. “We are excited about this discovery as it helps resolve a decade-long puzzle in ICF research. Our findings point the way to an improvement in the predictive capabilities of simulations, which is crucial for the success of future fusion experiments.”
In NIF experiments, scientists use a device called a hohlraum—approximately the size of a pencil eraser—to convert laser energy into X-rays, which then compress a fuel capsule to achieve fusion.
For years, there has been a problem where the predicted X-ray energy (drive) was higher than what was measured in experiments. This results in the time of peak neutron production, or “bangtime,” occurring roughly 400 picoseconds too early in simulations. This discrepancy is known as the “drive-deficit” because modelers had to artificially reduce the laser drive in the simulations to match observed bangtime.

The experimental observation of a dissipative time crystal in a Rydberg gas
Posted by Shailesh Prasad in category: energy
A dissipative time crystal is a phase of matter characterized by periodic oscillations over time, while a system is dissipating energy. In contrast with conventional time crystals, which can also occur in closed systems with no energy loss, dissipative time crystals are observed in open systems with energy freely flowing in and out of them.

Spanish energy giant unveils two huge battery storage projects in Australia
Posted by Shailesh Prasad in category: energy
Spanish energy giant Iberdrola has revealed two new battery storage projects in Australia – its biggest yet in the country – that will take its total capacity to more than 1,500 gigawatt hours.
The new batteries are a 250 megawatt (MW)/ 500 megawatt hour (MWh) Gin Gin project near Bundaberg in Queensland – although its EPBC application describes it only as a 500 MW project – and the 270 MW, 1,080 MWh Kingswood project in New South Wales (NSW).
To date, Iberdrola’s non-gas firming portfolio has been on the smaller side, making up just a fraction of the company’s 2.4 GW of installed renewables in Australia.
