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.
Imagine stacking giant LEGO blocks to power your city – but instead of plastic, we''re talking 35-ton concrete monsters dancing to the rhythm of energy demand.
Researchers at MIT Cambridge are working on a new pathway for making ''supercapacitors'' out of three basic ''building'' materials such as cement, water, and carbon black, which can potentially store energy and
How does concrete energy storage work? It stores excess electricity as heat in concrete blocks using resistive heating elements, releasing energy through thermal exchange when needed.

Blocks of cement infused with a form of carbon similar to soot could store enough energy to power whole households. A single 3.5-meter block could hold 10kWh of energy, and power a house for a day, and the technology could be
We comprehensively review concrete-based energy storage devices, focusing on their unique properties, such as durability, widespread availability, low environmental impact, and advantages.
This unassuming technology is reshaping how we store renewable energy—and it''s doing so without fancy lithium or rare earth metals. In this deep dive, we''ll explore why square cement block energy storage systems are gaining traction from Switzerland to Silicon Valley.
Swiss company Energy Vault has just launched an innovative new system that stores potential energy in a huge tower of concrete blocks, which can be "dropped" by a crane to harvest the kinetic...
Researchers at MIT Cambridge are working on a new pathway for making ''supercapacitors'' out of three basic ''building'' materials such as cement, water, and carbon black, which can potentially store energy and sustainable support our clean energy needs.
Because concrete is a lot denser than water, lifting a block of concrete requires—and can, therefore, store—a lot more energy than an equal-sized tank of water.

Solar or wind energy is siphoned into one of these tower blocks, and then AI informs the concrete blocks to rise up. Following this, the blocks are then " returned to the ground, and the kinetic energy generated from the falling brick is turned back into electricity," as per the company's own description. Energy Vault concrete block.
The gradual shift to concrete-based materials in the energy storage sector presents an attractive opportunity for leveraging the durability, abundance, and cost-effectiveness of concrete. As evidenced by this review, concrete not only underpins current development but also forms the foundation for future energy storage systems.
The energy storage capacity of concrete-based systems needs to be improved to make them viable alternatives for applications requiring substantial energy storage. The integration of conductive materials, such as carbon black and carbon fibers, into concrete formulations can increase production costs.
The high surface area of concrete structures and their durability and abundance make them promising electrode materials for use in energy storage applications. The porous structure of concrete mixture provides abundant surface sites for electrochemical reactions, allowing for more efficient ion storage and transfer.
That said, Energy Vault claims that the concrete blocks don't degrade over time, but to us it seems like years of exposure to the elements could slowly wear away at them. Still, the company says the system should have a lifetime of 30 to 40 years.
Concrete-based energy storage devices face several challenges that need to be addressed for their successful implementation and commercialization. Both concrete-based batteries and supercapacitors currently face limitations in energy density compared to conventional lithium-ion batteries.
