Jackery recently showed off the EnergyGuard Max whole home energy storagesystem at their booth at IFA Berlin. The system pairs the Energycore 100kWh battery module with the PowerVault 50 inverter in weather-resistant enclosures. Also at their booth, I had the opportunity to talk with their CEO and founder, Jack Sun. … [continued]
For the same 25 MW / 100 MWh four-hour service, Energy Vault’s Rudong project requires far more capital, land, machinery and construction carbon than a contemporary Chinese BESS.
Energy Vault’s Rudong gravity-storage project is a particularly useful technology test because it removes many of the excuses that can surround a first-of-kind energy project. It was built in China, with deep domestic supply chains for concrete, steel, motors, power electronics and industrial construction. It had government support, grid coordination … [continued]
The bankruptcy of Ascend Elements was a hiccup, not a halt, to an advanced battery recycling facility in Georgia, providing EV stakeholders and other industries with a new, domestic source of lithium carbonate.
Renewable energy and storage are credited with resolving longstanding grid reliability issues in Texas, even during extreme hot weather.
IFA Berlin, which stands for “Innovation For All,” is a diverse technology show. There were numerous mobile, entertainment and AI-enabled devices, but there were also a range of clean technology products. On the first day of IFA, I saw several different paths to sustainability. Products from large companies and small … [continued]
How to deliver resilient critical raw material supply chains, vital for Europe’s clean tech, with investment, partnerships and industrial policy. The EU is heavily dependent on imports of raw materials and is failing to catch up with investments globally. At the same time, the recent energy crisis has highlighted the … [continued]
Donut Lab revealed its solid-state battery to the world at CES 2026, to the amazement of many and to the dismay of others shocked by their achievement and performance claims. No other company has a practical fully solid-state battery in production as of this writing. Many, like Quantumscape, have tried … [continued]
Hydrogen’s detour persisted because incumbent assets, skills and institutions had reasons to keep the molecule economy politically viable after the economics weakened.
In 2023, a senior executive responsible for decarbonizing a major transportation company asked me, with some exasperation, what drove the “madness on hydrogen.” Hydrogen proposals kept arriving for applications where the energy balance and economics looked dreadful. That conversation became What Drives This Madness On Hydrogen?, an attempt to explain … [continued]
In general, there’s far more concern about electric car range and electric car battery longevity than there needs to be. We’ve got a 2019 Tesla Model 3 SR+ and a 2018 BMW i3 REx and just need to charge them up once or twice a week overnight at home. Electric … [continued]
U.S. battery energy storage capacity nearly doubles in the first 18 months of the Trump administration as grid operators turn to storage to strengthen grid reliability WASHINGTON, D.C. — The U.S. energy storage industry installed a record 20.2 gigawatt-hours (GWh) of new capacity in Q2, bringing total installations in the … [continued]
