Energy Vault has built a gravity battery in China

Short description

Summarize this content to 100 words Swiss company Energy Vault has announced the completion of construction of a large gravity storage facility in China that will help balance the electricity generation of a wind farm, and is now in the “commissioning” phase before being connected to the grid.The EVx gravity storage system works on the principle of raising and lowering concrete blocks to store and release potential energy and allows for the storage of 100 MW*h of energy, which it can output with a capacity of 25 MW. Built in Jiangsu province, it is the world’s first commercial gravity energy storage system, excluding pumped storage systems that provide the majority of all energy storage in the world, according to Energy Vault.Gravity storage has been proposed by a number of companies as a way to store solar and wind energy produced during periods of low demand. For example, on a sunny day, the energy produced by a solar power plant can be stored as potential energy by lifting concrete blocks. In the evening, the blocks can be lowered, triggering the dynamo machines that supply electricity at the right moment.Commentators have questioned the practicality of gravity storage, arguing that they store a relatively small amount of energy compared to that energy. Spent on the production of concrete and steel used in their construction. Clean-energy website CleanTechnica called the concept “horribly stupid in obvious ways,” citing the fragility of the crane systems and the huge energy costs (and greenhouse gas emissions) involved in making the concrete blocks used in Energy’s Swiss-built EV1 prototype in 2020 with the characteristics of 5 MW and 35 MW*h.Energy Vault claims that the new EVx design, in which the elevators are inside the building, addresses these issues, and plans to use fly ash and other waste in the blocks instead of concrete. The company also claims that it has managed to increase the efficiency of the EV1 to 75% (meaning that the system returns 75% of the stored electrical energy), reaching the promised 80%.In March 2022, the company, together with partners Atlas Renewable and China Tianying (CNTY), began installing the system in Rudong City (Jiangsu Province), and the system has now “entered the first phases of commissioning,” according to Energy Vault’s announcement.”We are pleased to share with our partners Atlas Renewable and China Tianying our successes and milestones in the commissioning of the world’s first EVx gravity energy storage system,” said Robert Piconi, Chairman and Chief Executive Officer of Energy Vault. “We look forward to the opportunity to share this first EVx system and our future plans to deploy gravity technology around the world as we see growing demand for longer-lasting energy storage systems.”According to Piconi, there were two shutdowns due to Covid in the first year of construction, but now the company is ready to implement larger energy storage projects, and its partner – China Tianying – announced the start of another 100-capacity gravity energy storage project MW*h in Huailai County, Hebei Province. The project, which will be located in the city of Kunrui, will provide stable and environmentally friendly electricity to data centers in the region, according to Energy Vault.
