Physicists uncover key to resolving long-standing inertial confinement fusion hohlraum drive deficit

Posted by 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 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 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 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.

Tesla secures absurdly large multi-billion Megapack contract

Posted by in category: energy

Tesla has secured an absurdly large contract to provide over 15 GWh of Megapack to California’s Intersect Power.

The Megapack has become the go-to, posterchild product for large-scale energy storage around the globe.

It’s by far Tesla’s fastest-growing product and enabled the company to deploy a record of 9.4 GWh of energy storage last quarter – more than twice the last record.

Something in space has been pulsing every 22 minutes for at least 35 years

Posted by in categories: energy, physics, space

Researchers reported the discovery of a new cosmic conundrum. The new object, GPM J1839-10, operates similarly to a pulsar, emitting frequent bursts of radio radiation. However, the physics that drives pulsars dictates that they would cease generating if they slowed too much, and practically every pulsar we know of blinks at least once every minute.

GPM J1839-10 has a pulse interval of 22 minutes. We don’t know what type of physics or things can power it.

Researchers develop novel electrode for improving flowless zinc-bromine battery

Posted by in categories: energy, sustainability

Due to rising environmental concerns, global energy production is shifting from fossil fuels to sustainable and renewable energy systems such as solar and wind power. Despite their advantages, they have two significant weaknesses: volatile power production and irregular supply. Hence, they are augmented with energy storage systems (ESSs).

Lithium-ion batteries are at the forefront of ESSs but are prone to fires due to flammable electrolytes and lithium-based materials. The flowless zinc-bromine battery (FLZBB), which uses non-flammable electrolytes, is a promising alternative, offering and a simple battery platform.

An FLZBB consists of a positive electrode, a , an electrolyte, and a separator to keep the electrodes apart. Unlike conventional zinc-bromine batteries, the electrolyte in FLZBB does not need to be pumped and is instead held in a gel-like container. Graphite felt (GF) is widely used as an electrode in many redox batteries due to its stability in acidic electrolytes.
