In addition to the successful testing of the Rudong EVx, Energy Vault announced the extension of its EVx licensing agreement with Atlas Renewable from 7.5 to 15 years, reflecting the key role that gravity storage technology is set to play in the transition energy of China and in achieving China’s decarbonization goals. . Over the past 12 months, CNTY announced eight additional EVx GESS deployments across multiple provinces in China, totaling more than 3.7 GWh, which will generate future project royalty streams for Energy Vault as the systems are built and commissioned.

“The successful testing and commissioning of the Rudong EVx, the world’s first grid-scale gravity energy storage system, is an important milestone for Energy Vault, our local partners Atlas and CNTY, and especially for China and its progress toward achieving its sharpness goals. carbon neutrality,” said Robert Piconi, President and CEO of Energy Vault. “These tests demonstrate that gravity energy storage technology promises to play a key role in supporting the energy transition and decarbonization goals of China, the world’s largest energy storage market. We are also pleased to announce that our EVx license and royalty agreement with Atlas Renewable and CNTY has been extended for an additional 7.5 years through 2036, and we look forward to continuing this strong partnership as New systems will be deployed in volume in the coming years. .”

In January 2024, the Rudong EVx was selected as part of a list of projects classified as “new energy storage demonstration pilot projects” by the China National Energy Administration (NEA). Projects selected as demonstration pilots benefit from increased management oversight by provincial energy authorities, enabling coordination to support progress related to construction, data reporting, compliance and safety measures, among other questions of interest.

Commissioning of the 25 MW/100 MWh GESS EVx began in the second half of 2023, followed by the completion in September 2023 of the final four-kilometer 35 kV overhead power line to the end substation existing remote area, recovery and completion of construction of the facility. in October and full grid interconnection in December. Following final provincial and state approvals for the start of commercial operation of the state’s grid, the Rudong EVx will be the world’s first commercial-scale unpumped hydrogravity energy storage system .
