BYD unveils world's largest 14.5 MWh DC energy storage system

news.ycombinator.com Marija Maisch 2025-09-20 03:28:20

BYD has unveiled a new DC energy storage system with the world’s largest single-unit capacity of 14.5 MWh, raising the bar in the rapidly evolving utility-scale storage market. The system, named “HaoHan,” was officially launched on September 18 at the International Digital Energy Expo in Shenzhen. The company said HaoHan’s minimum unit capacity of 14. 5MWh is more than double the industry norm of 6–7 MWh. When configured within a standard 20-foot container, the system delivers 10 MWh and achiev

Octopus Energy spins off its Kraken utility billing and AI platform

techcrunch.com Tim De Chant 2025-09-21 01:28:03

British renewable energy provider Octopus Energy said this week that it’s spinning off Kraken, its tech platform for utilities, spurred in part by $500 million in committed annual revenue from other utilities and energy providers. An eventual Kraken IPO could be valued at $15 billion and could occur within a year, according to The Wall Street Journal. Kraken was actually the company’s initial product, according to Octopus CEO Greg Jackson. “We created Octopus as the ‘demo client,’” he told the

How Energy-Generating Sidewalks Work

wired.com Rhett Allain 2025-09-21 18:00:00

We walk here, we walk there, we walk everywhere. Maybe you’re headed to work or to lunch in a busy city. You’re expending energy, and the exercise is good for you. But what if, on top of that, we could recapture all that freely supplied energy and convert it to usable electricity? This is a real thing. Systems have been installed in dozens of countries. Check out this video. And why stop there? You could put them in discotheques and harness that fancy footwork to power the strobe lights. Or bui

The Download: AI-designed viruses, and bad news for the hydrogen industry

Artificial intelligence can draw cat pictures and write emails. Now the same technology can compose a working genome. A research team in California says it used AI to propose new genetic codes for viruses—and managed to get several of them to replicate and kill bacteria. The work, described in a preprint paper, has the potential to create new treatments and accelerate research into artificially engineered cells.

Around 90% of an Earthquake’s Energy Doesn’t Do What You Think It Does

gizmodo.com Gayoung Lee 2025-09-27 05:30:30

Earthquakes can be deadly and disastrous. But what we feel may constitute a tiny sliver of an earthquake’s destructive energy, according to a new experiment. In a recent AGU Advances paper, researchers describe how they created “lab quakes,” or miniature versions of natural earthquakes created in a controlled laboratory. Doing so allowed the team to derive a complete energy budget for the quakes, a “simplified analog” of real-life earthquakes, they reported in the paper. Surprisingly, they fou

After escaping Russian energy dependence, Europe is locking itself in to US LNG

EU Energy Commissioner Dan Jorgensen met US Energy Secretary Chris Wright in Brussels on 11 September. Following her State of the European Union address to the European Parliament last week, EU Commission President Ursula von der Leyen got an earful from MEPs angry about her “surrender deal” with Donald Trump. Iratxe Garcia Perez, leader of the centre-left S&D group, blasted von der Leyen’s hypocrisy in calling for Europe to have courage and fight when she herself showed no courage with Trump.

Rodatherm Energy wants to make geothermal more efficient, but will it be cheaper?

Rodatherm Energy, a new geothermal startup, emerged from stealth Monday with $38 million in funding and a plan to build a pilot plan in Utah. The startup differentiates itself by plumbing its boreholes with a closed loop, likely made of steel, that’s filled with a refrigerant. That contrasts with other enhanced geothermal companies, which tend to use water to transport heat from deep within the Earth.

Tesla Engineer Quits, Roasts Elon Musk in Spectacular Fashion
