First American sodium-ion battery factory will make cells with lifespan of 50,000 cycles that charge in 10 minutes

Posted by in categories: chemistry, energy, sustainability, transportation

Built by Natron Energy, the Edgecombe County facility is planned for 24 GWh of annual capacity, which would turn Natron from a startup into the first sodium-ion battery production juggernaut on US soil.

Sodium-ion batteries are cheaper, safer, with much longer lifespan and faster charging than conventional Li-ion packs.

Chinese companies are already using them in grid-level energy storage systems of local utilities, to balance their renewable energy mix. Some sodium-ion battery packs are even making their way into electric vehicles there, even though the chemistry offers lower energy density than Li-ion batteries.

Dormant capacity reserve in lithium-ion batteries detected

Posted by in categories: energy, materials

Lithium iron phosphate is one of the most important materials for batteries in electric cars, stationary energy storage systems and tools. It has a long service life, is comparatively inexpensive and does not tend to spontaneously combust. Energy density is also making progress. However, experts are still puzzled as to why lithium iron phosphate batteries undercut their theoretical electricity storage capacity by up to 25% in practice.

In order to utilize this dormant capacity reserve, it would be crucial to know exactly where and how lithium ions are stored in and released from the during the charging and discharging cycles.

Researchers at Graz University of Technology (TU Graz) have now taken a significant step in this direction. Using transmission electron microscopes, they were able to systematically track the lithium ions as they traveled through the battery material, map their arrangement in the crystal lattice of an iron phosphate cathode with unprecedented resolution and precisely quantify their distribution in the crystal.

Australia needs 126 GW of solar, wind by 2030 to hit net zero by 2050, says BNEF

Posted by in category: energy

Australia can still reach its net-zero energy goal by 2050, according to BloombergNEF (BNEF), but there is no time to waste, with a need for significant investments in solar, wind, and energy storage to stay on track.

Engineers develop eco-friendly cooling device with record-breaking efficiency

Posted by in categories: energy, sustainability

Researchers at the School of Engineering of the Hong Kong University of Science and Technology (HKUST) have developed an eco-friendly refrigeration device with record-breaking cooling performance, setting the stage for transforming industries reliant on cooling and reducing global energy use.

With a boost in efficiency of over 48%, the new elastocaloric technology opens a promising avenue for accelerating the commercialization of this disruptive technology and addressing the associated with traditional cooling systems.

Traditional vapor compression refrigeration technology relies on refrigerants of high global warming potential. Solid-state elastocaloric refrigeration based on latent heat in the cyclic phase transition of shape memory alloys (SMAs) provides an environmentally friendly alternative, with its characteristics of greenhouse gas-free, 100% recyclable and energy-efficient SMA refrigerants.

Low-cost iron-air technology to feature in world’s biggest battery project in US

Posted by in categories: energy, sustainability

American energy storage technology newcomer Form Energy says it has received funding to deploy a groundbreaking 85 MW/8.5 GWh iron-air multi-day battery, which will be capable of up to 100 hours of storage and will be the world’s biggest battery once built.

The US Department of Energy last week announced $US389 million ($A579 million) in funding for the Power Up New England project which seeks to unlock up to 4.8GW of additional offshore wind and innovative battery energy storage systems in the local grids to boost resilience and optimise the delivery of renewable energy.

Part of the Power Up New England project, and easily the most exciting, is the 85 MW/8,500 MWh iron-air battery system to be built on the site of a former paper mill in rural Maine.

New technology extracts lithium from brines inexpensively and sustainably

Posted by in categories: chemistry, energy, sustainability, transportation

A new technology can extract lithium from brines at an estimated cost of under 40% that of today’s dominant extraction method, and at just a fourth of lithium’s current market price. The new technology would also be much more reliable and sustainable in its use of water, chemicals, and land than today’s technology, according to a study published in Matter by Stanford University researchers.

Global demand for lithium has surged in recent years, driven by the rise of electric vehicles and renewable energy storage. The dominant source of lithium extraction today relies on evaporating brines in huge ponds under the sun for a year or more, leaving behind a lithium-rich solution, after which heavy use of potentially toxic chemicals finishes the job. Water with a high concentration of salts, including lithium, occurs naturally in some lakes, hot springs, and aquifers, and as a byproduct of oil and natural gas operations and of .

Many scientists are searching for less expensive and more efficient, reliable, and environmentally friendly lithium extraction methods. These are generally direct lithium extraction that bypasses big evaporation ponds. The new study reports on the results of a new method using an approach known as “redox-couple electrodialysis,” or RCE, along with cost estimates.

Houston now has its first grid-scale battery storage facility

Posted by in categories: energy, space

Jupiter Power, an Austin-based energy developer, owns and operates the project at Hiram Clarke Road and U.S. 90 at the site of the former H.O. Clarke gas-fired power plant. It’s a 200-megawatt facility, enough to power 50,000 Texas homes during the hottest summer days, with the ability to discharge power at maximum capacity for two hours.

On any given day, the Houston area must import about 60% of its needed electricity from other parts of the state where power plants are more plentiful. This often results in a phenomenon known as congestion: Low-cost electrons are clogged on power lines into Houston much like commuters on the highway during rush hour, which raises the wholesale cost of electricity in the region. These wholesale price spikes are initially paid by retail electric providers and can eventually be passed onto consumers.

Ever see a Star Explode? You’re about to get a chance very soon

Posted by in categories: energy, physics, space

Every clear night for the last three weeks, Bob Stephens has pointed his home telescope at the same two stars in hopes of witnessing one of the most violent events in the universe—a nova explosion a hundred thousand times brighter than the sun.

The eruption, which scientists say could happen any day now, has excited the interest of major observatories worldwide, and it promises to advance our understanding of turbulent binary star systems.

Yet for all the high-tech observational power that NASA and other scientific institutions can muster, astrophysicists are relying on countless amateur astronomers like Stephens to spot the explosion first.
