The answer may lie in towers of massive concrete blocks stacked hundreds of feet high that act like giant mechanical batteries, storing power in the form of gravitational potential energy. This new energy storage concept is being advanced by a Californian/Swiss startup company called Energy Vault as a solution to renewable energy''s

The battery is charged by using excess electricity to power crane motors which lift concrete blocks. The higher a block is lifted, the more potential energy it has stored.

A startup called Energy Vault is working on a unique storage method, and they must be on the right track, because they just received over $100 million in Series C funding last week. The method was inspired by pumped hydro, which has been around since the 1920s and uses surplus generating capacity to pump water up into a reservoir.
Energy Vault, a start up from Switzerland, uses concrete blocks and cranes to produce and store energy; a proposed alternative to pumped hydroelectric storage, which makes up 96% of the world''s storage capacity. The technology relies on energy stored when something is lifted against gravity. The density of concrete will store more energy than
A Startup That''s Storing Energy in Concrete Blocks Just Raised $100 Million. By Vanessa Bates Ramirez. September 1, 2021. Energy Vault says the towers will have a storage capacity up to 80 megawatt-hours, and be able to continuously discharge 4 to 8 megawatts for 8 to 16 hours. The technology is best suited for long-duration storage with
Robert Piconi, CEO & Co-Founder of Energy Vault stated: "Energy Vault''s technology is designed to provide a cost-efficient, flexible and sustainable energy storage solution to meet the immediate needs of utilities, power producers and large industrial energy consumers that must solve the problem of power intermittency
How does Energy Vault plan to store energy? The company''s storage facility looks like this: an almost 120 meter– (400 foot-) tall, six-armed crane of custom-built concrete blocks. Each block
Cemex Ventures has announced an investment in a company that has developed a technology to store energy by raising concrete blocks using a bespoke crane. The investment in Energy Vault is to be reinforced by support for rapid market adoption and deployment of the technology through Cemex''s strategic network.
Energy Vault offers two types of product: long-term storage using concrete blocks and gravity energy, and more conventional products, short-term storage (apparently mainly battery-based) and a charge management software suite.
Swiss start-up Energy Vault is providing a solution by storing extra energy as potential energy in concrete blocks. Their innovative energy storage technology consists of a combination of 35 tons solid concrete blocks and a tall tower. The 120-meter (nearly 400-foot) tall, six-armed crane lifts the blocks 35 stories high into the air when there
Swiss startup Energy Vault has a different idea. According to Quartz, it plans to construct energy storage systems that use concrete blocks. A 400′ tall crane with 6 arms uses excess electricity
Energy Vault settled on its current design after evaluating several other options — gravel in carts, water in tanks, concrete blocks hanging from cranes. The EVx is designed to overcome problems with those designs. It's weatherproof, which means bricks don't get wet or blown around, for example.
The maximum output will be 25MW at the China system and 18MW at the Texas system. Energy Vault settled on its current design after evaluating several other options — gravel in carts, water in tanks, concrete blocks hanging from cranes. The EVx is designed to overcome problems with those designs.
Renewable energy is billed as a clean source of power that will free civilization from the dirty, CO 2 -generating fossil fuels that drive climate change. But it has a problem.

And its stock has slumped by 89% over the last year, a fate many startups suffered with economic troubles and skeptical investors. Energy Vault's Piconi is convinced the company is on the right path toward making energy storage more economical, though.

Source: Energy Vault In addition to supplying a flexible reserve of energy to compensate for the intermittency of renewables, the towers have the potential to provide other important ancillary services to maintain grid stability and reliability.
Energy Vault tested its technology at a smaller scale in Switzerland, where the 170-person company is headquartered. Its two EVx systems under construction are much bigger.
The European energy storage market is booming with Germany leading residential adoption (+58% YoY) thanks to €500/kWh subsidies. Italy's new tax credits drive 5.2GWh commercial deployments, while UK grid-scale projects exceed 8GWh with 2-hour duration systems. Key selection criteria: German-certified safety (VDE-AR-E 2510), 10+ year warranties, and VPP readiness. Top-performing products include Sonnen's hybrid inverters (98% efficiency) and BYD's Blade Battery (12,000 cycles @80% DoD). For snowy regions like Scandinavia, consider Huawei's -30°C compatible systems. France mandates carbon footprint declarations - Sungrow's ISO-14067 certified solutions gain preference.
For European homeowners, 5-10kWh systems with 3-phase compatibility are ideal. Top picks: 1) Tesla Powerwall 3 (13.5kWh, 97% round-trip efficiency) for smart home integration; 2) LG Chem RESU Prime for compact urban installations; 3) SMA Sunny Boy Storage for retrofit projects. Critical features: EU-made battery cells (exempt from CBAM tariffs), dynamic tariff optimization (like Octopus Energy integration), and fire-safe LiFePO4 chemistry. Southern Europe demands 85%+ depth of discharge capability, while Nordic markets require -25°C operation. Always verify CEI 0-21 compliance for Italian grid connection and EnWG certification for German feed-in.
