Indian utility NTPC Ltd. wants to deploy Switzerland-based Energy Vault’s EVx gravity-based energy storage technology and software solutions to support its clean energy initiatives.
The two parties recently signed a memorandum of understanding (MoU) to forge a long-term strategic partnership. NTPC will deploy Energy Vault’s EVx gravity-based energy storage technology and software solutions based on the outcome of a joint feasibility study.
Energy Vault’s EVx storage system is comparable to pumped hydro, using grid-scale renewable energy when supply is abundant to drive motors and raise 30-ton blocks on a six-arm crane tower, rather than water, up to a height. When power needs to be discharged back to the grid, the blocks are lowered, harvesting the kinetic energy.
The NTPC and Energy Vault collaboration will also see the beneficial use of coal ash to manufacture composite blocks for Energy Vault’s gravity-based energy storage system.
“Energy Vault’s mission is to make sustainable, carbon-free energy a reality, and this announcement marks further advancement towards that goal with the expansion into one of the largest global markets for energy,” Robert Piconi, the chairman, co-founder and CEO of Energy Vault. “Our collaboration with NTPC builds upon previously announced commercial expansions across multiple continents as we transitioned to a public company earlier this year.”
