New molten salt battery for grid-scale storage runs at low temp and cost

Posted by in categories: energy, sustainability

As renewable forms of power like wind and solar continue to gain prominence, there will be a need for creative solutions when it comes to storing energy from sources that are intermittent by nature. One potential solution is known as a molten salt battery, which offers advantages that lithium batteries do not, but have their share of kinks to iron out, too. Scientists at Sandia National Laboratories have come up with a new design that addresses a number of these shortcomings, and demonstrated a working molten salt battery that can be constructed far more cheaply, while storing more energy, than currently available versions.

Storing vast amounts of energy in a cheap and efficient manner is the name of the game when it comes to powering whole cities with renewable energy, and despite its many strengths, this is where expensive lithium battery technology falls short. Molten salt batteries shape as a more cost-effective solution, which use electrodes kept in a molten state with the help of high temperatures. This is something that the Sandia scientists have been working to change.

“We’ve been working to bring the operating temperature of molten sodium batteries down as low as physically possible,” says Leo Small, the lead researcher on the project. “There’s a whole cascading cost savings that comes along with lowering the battery temperature. You can use less expensive materials. The batteries need less insulation and the wiring that connects all the batteries can be a lot thinner.”

Making clean hydrogen is hard, but researchers just solved a major hurdle

Posted by in categories: chemistry, information science, solar power, sustainability

For decades, researchers around the world have searched for ways to use solar power to generate the key reaction for producing hydrogen as a clean energy source—splitting water molecules to form hydrogen and oxygen. However, such efforts have mostly failed because doing it well was too costly, and trying to do it at a low cost led to poor performance.

Now, researchers from The University of Texas at Austin have found a low-cost way to solve one half of the equation, using sunlight to efficiently split off oxygen molecules from water. The finding, published recently in Nature Communications, represents a step forward toward greater adoption of hydrogen as a key part of our energy infrastructure.

As early as the 1970s, researchers were investigating the possibility of using solar energy to generate hydrogen. But the inability to find materials with the combination of properties needed for a device that can perform the key chemical reactions efficiently has kept it from becoming a mainstream method.

Tesla Gigafactory Texas is taking shape in new drone flyover video

Posted by in categories: drones, sustainability

A new drone flyover of Tesla Gigafactory Texas is showing some great progress, and it’s even starting to look like the render of the finished building.

The start of production at Gigafactory Texas and Gigafactory Berlin is the most important thing for Tesla’s growth this year.

Tesla Launches Megapack Order Page & Pricing

Posted by in categories: energy, sustainability

According to the order page, the price in California starts at $1235, 890, and Tesla requires $5000 down. This doesn’t include taxes or annual maintenance. Prices do vary by state. Customers can order up to 1000 Megapacks, and if they do, the costs per unit decline with each additional Megapack order.

On its website, Tesla said that it took everything it knew about battery technology to enable the world’s largest energy projects. For these giga-scale projects, a 1 gigawatt-hour (GWh) project provides enough energy storage capacity to power every home in San Francisco for 6 hours.

For those ordering the Tesla Megapack, the earliest deliveries will occur in 2022, but not for all states. California, Nevada, and Texas have 2022 delivery estimates, while others, including my own state of Louisiana, have 2023 estimated delivery dates. The price of the Megapack for Louisiana is $1252, 810.

Solid State Batteries — Autumn 2021 mass production in Japan. Is it FINALLY happening?

Posted by in categories: neuroscience, sustainability

Solid state batteries are the long-promised Holy Grail of battery technology. They’re smaller and better than existing Lithium Ion batteries. They charge more quickly and last much longer. What’s not to like? Trouble is, no-one’s managed to mass produce one at any useful scale yet. Turns out it’s quite tricky to make them reliable! Now though, two major Japanese companies are finally firing up their full production lines. So will 2021 be the year?
