An international research team has designed a residential solar-plus-storage system based on gravity. The system was built with a solar power generator, a bulk booster charge controller, an inverter, ...

Swiss startup Energy Vault came out of stealth mode in 2018, and has been on an upward trajectory since then. The company created a system to store electricity by elevating concrete blocks, and ...

Gravity-based energy storage, like pumped-hydro, is based on simple principle: use energy during the charging phase of the system to transport a solid mass from a lower location to an higher level and ...

A global race is underway to find long-term energy storage solutions, with venture capital investing heavily in new technologies beyond the current lithium-ion battery dominance. Researchers at the ...

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. Towering (some might say, decadent) superstructures continue to ...

Energy innovators around the world plan to harvest more power from abandoned coal mines, but not by digging up dirty deposits. Instead, this concept utilizes gravity and renewable energy to transform ...

For the global energy transition to succeed, the energy storage industry will have to develop cheap, efficient, and reliable ways to store renewable energy. Lithium-ion batteries currently dominate ...

As the world grapples with transitioning away from fossil fuels, engineers are hard at work to integrate new types of generation into the power grid. There’s plenty of challenges, particularly around ...
