Texas Embraces Energy Vault’s Gravity-Based Storage
Swiss startup Energy Vault is revolutionizing the energy storage arena with its eco-friendly and groundbreaking concept, targeting enhanced resilience and sustainability of the electric grid.
Revolutionizing the Electric Grid
According to Futurism, the company has initiated construction on two enormous facilities in Texas and near Shanghai to test its idea of storing energy with colossal 24 metric-ton compressed dirt bricks.
Energy Vault is constructing two facilities in Texas and near Shanghai to test its idea of storing energy with colossal 24 metric-ton compressed dirt bricks.
If successful, this ingenious approach could drastically lower energy storage costs.
Harnessing Gravity for Renewable Energy Storage
Energy Vault's method is remarkably simple. Cranes lift the bricks to upper levels during times of excess renewable energy, storing vast power quantities.
When energy demand surges and supply wanes, the bricks are lowered, unleashing stored energy.
This idea could store solar and wind energy far more affordably than complex lithium-ion-based solutions.
The company built a smaller pilot system in Switzerland, generating an impressive five megawatts.
However, the new Chinese facility boasts a 400-foot height and 100 megawatt-hour storage capacity, enough to power 3,400 homes for a day.
Compressed Dirt Bricks: The Future of Energy Storage?
The Texas facility aims to provide a nearby power company with 36 megawatt-hours of capacity.
Comprising 99 percent compressed dirt, water, and polymer, the bricks are stored inside a massive rectangular building.
A trolley system transports the bricks to and from an elevator.
Each brick lowered at six feet per second, generates a megawatt of power, achieving 80 percent overall efficiency.
Texas Facility Aims to Reduce Fossil Fuel Dependence
This innovative solution could enable utilities to adapt to a fast-changing energy landscape and reduce fossil fuel reliance.
Energy Vault's CEO, Robert Piconi, emphasizes that storage is crucial for transitioning from fossil fuels to intermittent renewable generation.
