“Electric water heaters offer a cheap way to store large amounts of energy, in the form of hot water. A heater with a 300-litre tank can store about as much energy as a second-generation Tesla Powerwall – at a fraction of the cost.”

Australia’s energy transition is well under way. Some 3 million households have rooftop solar and sales of medium-sized electric cars are surging. But as we work towards fully electric households powered by renewable energy, have we overlooked a key enabling technology, the humble electric water heater?

About half of Australian households use electric water heaters, while the rest use gas. So what’s so great about electric water heaters?

Juan Bernabé-Moreno is IBM’s director of research for Ireland and the United Kingdom. The Spanish computer scientist is also responsible for IBM’s climate and sustainability strategy, which is being developed by seven global laboratories using artificial intelligence (AI) and quantum computing. He believes quantum computing is better suited to understanding nature and matter than classical or traditional computers.

Question. Is artificial intelligence a threat to humanity?

Answer. Artificial intelligence can be used to cause harm, but it’s crucial to distinguish between intentional and malicious use of AI, and unintended behavior due to lack of data control or governance rigor.

Less than a week after announcing a Power Day 2023 event to unveil new battery technologies, ZEEKR has officially introduced its own lithium iron phosphate (LFP) cells developed in-house. While LFP batteries are generally categorized as less energy-dense, ZEEKR says its cells outperform many competitors.

While many companies have begun decelerating in 2023 as we enter the busy holiday season, ZEEKR has shown no signs of slowing down. In November, the Geely-owned automaker announced a new model called the 7, which made its public debut during the Guangzhou Auto Show. Since then, we’ve seen the company file for a US IPO and have confirmed plans for a new mass-market SUV to compete with the Tesla Model Y.

The ZEEKR 7 sedan will officially launch in China on December 27, followed by deliveries a few days later. Before then, however, ZEEKR promised a live event to debut new technology pertaining to EV batteries developed entirely in-house.

Tesla has released a new comparison report claiming Powerwall with solar is cheaper than a traditional backup generator.

For years now, Tesla has enjoyed a giant backlog of Powerwall orders, but now that production has ramped up, the automaker has worked through most of that backlog, and it has to start generating more demand for the home energy storage product.

Tesla has now released a new report that compares Powerwalls as a backup system to backup generators.

Fourth Power says its ultra-high temperature “sun in a box” energy storage tech is more than 10X cheaper than lithium-ion batteries, and vastly more powerful and efficient than any other thermal battery. It’s hoping to prove it with a 1-MWh prototype.

As a grid-level energy storage solution, Fourth aims to compete with big lithium battery arrays in the short-duration 5–10 hour range – basically storing excess solar energy during the heat of the day for use in the evening and at night when generation drops off. But the company says it’s also relevant up to the 100-hour stage, which would cover the “several days of bad weather and poor renewable generation” case.

This is one of a number of thermal energy storage companies coming up out of Massachusetts and backed by Bill Gates’s Breakthrough Energy Ventures fund. You might remember Antora Energy from a few months ago, with its ultra-hot carbon block batteries and high-efficiency thermophotovoltaic energy converters, for example.

The $25,000 Tesla Model 2 is a revolutionary and cost-effective option that aims to make sustainable mobility more accessible and change the EV landscape dramatically.

Tony Seba just made this insane solar prediction that is blowing my mind.

Tesla’s potential market size for its humanoid robot, Optimus, presents a massive opportunity worth trillions of dollars, far surpassing the impact of their electric vehicles.
