SoftBank''s Vision Fund is investing $110 million in the Swiss startup Energy Vault, which stores energy in stacked concrete blocks. Two things make this investment unprecedented. First, it''s an unusually large sum for a company that hasn''t even existed for two years or built a full-scale prototype. Second, by making an energy storage bet, the …
Concrete with smart and functional properties (e.g., self-sensing, self-healing, and energy harvesting) represents a transformative direction in the field of construction materials. Energy-harvesting concrete has the capability to store or convert the ambient energy (e.g., light, thermal, and mechanical energy) for feasible uses, …
About 96% of the world''s energy-storage capacity comes in the form of one technology: pumped hydro. Whenever generation exceeds demand, the excess electricity is used to pump water up a dam. When demand exceeds generation, that water is allowed to fall—thanks to gravity—and the potential energy turns turbines to produce …

Lift Energy Storage Technology (LEST) is a gravitational-based storage solution. Energy is stored by lifting wet sand containers or other high-density materials, transported remotely in and out of the lift with autonomous trailer devices. The system requires empty spaces on the top and bottom of the building.
SoftBank Group Corp.''s massive Vision Fund is making its first-ever energy storage bet -- and it''s on a rather unconventional type of battery. The fund, created by Japanese tech giant SoftBank ...
A new, low-cost energy concrete storage system could make sustainable power available 24/7, no batteries needed.
The concrete blocks have a storage capacity of up to 80 megawatt-hours and can continuously provide 4 to 8 megawatts for 8 to 16 hours. Energy Vault has been operating in stealth mode for the last couple of years. Though, Energy Vault doesn''t even have its full-scale prototype ready yet. But it''s much closer to deploying the technology.
The crane uses excess energy from renewables to lift concrete blocks, and when the power is required, the crane lifts blocks, and the generator produces it. The process is similar to a pumped-storage hydropower plant (HPP), with water substituted with concrete blocks and gravity doing the rest. The energy storage technology has been …
The performance of a 2 × 500 kWh th thermal energy storage (TES) technology has been tested at the Masdar Institute Solar Platform (MISP) at temperatures up to 380 C over a period of more than 20 months. The TES is based on a novel, modular storage system ...
