Taking its inspiration from hydropower, Switzerland-based start-up company Energy Vault has developed a new kind of storage method. The system essentially harnesses the power of the Earth’s gravitati. Energy Vault has created a new storage system in which a six-arm crane sits atop a 33-storey tower, raising and lowering concrete blocks and storing energy in a similar method to pumped hydropower stations.

[pdf] Recent pricing trends show 20ft containers (1-2MWh) starting at $350,000 and 40ft containers (3-6MWh) from $650,000, with volume discounts available for large orders.
[pdf] How much does a 100 degree solar energy storage cabinet cost? A 100-degree solar energy storage cabinet typically costs between $1,500 and $4,500, depending on various factors such as brand, size, features, and installation requirements.
[pdf] While a container can go for anywhere from $1,200 through $10,000, the evolving requirement for the electrical, plumbing, insulation, and finishing materials for the conversion to a living area is what hits the real price tag.
[pdf] In 2025, average turnkey container prices range around USD 200 to USD 400 per kWh depending on capacity, components, and location of deployment. But this range hides much nuance—anything from battery chemistry to cooling systems to permits and integration.
