The 25 MW/100 MWh EVx™ Gravity Energy Storage System (GESS) is a 4-hour duration project being built outside of Shanghai in Rudong, Jiangsu Province, China. The EVx™ is under construction directly adjacent to a wind farm and national grid.
The research and development of the gravity energy storage system has been based in Ticino and operational since 2019 with its own R&D centre. The commercial demonstration unit has been connected to the Swiss national utility grid and used for two years of testing and software commissioning.
The firm’s technology works by raising weights in a deep shaft and releasing them when energy is required. The technology is similar to that employed by Switzerland-headquartered and NYSE-listed Energy Vault, whose CEO Robert Piconi provided an update to its first commercial gravity energy storage project in Rudong, China, in a shareholder letter.
The company's first commercial grid-scale project using its proprietary gravity energy storage technology in Rudong, near Shanghai, was connected to the grid in December 2023 and can store up to 100 MWh. In other words, this is enough electricity to power nine homes for a whole year just from stored energy.
Gravitricity and Energy Vault have progressed their gravity energy storage solutions, with project updates in USA/Germany and China.

The global solar storage container market is experiencing explosive growth, with demand increasing by over 200% in the past two years. Pre-fabricated containerized solutions now account for approximately 35% of all new utility-scale storage deployments worldwide. North America leads with 40% market share, driven by streamlined permitting processes and tax incentives that reduce total project costs by 15-25%. Europe follows closely with 32% market share, where standardized container designs have cut installation timelines by 60% compared to traditional built-in-place systems. Asia-Pacific represents the fastest-growing region at 45% CAGR, with China's manufacturing scale reducing container prices by 18% annually. Emerging markets in Africa and Latin America are adopting mobile container solutions for rapid electrification, with typical payback periods of 3-5 years. Major projects now deploy clusters of 20+ containers creating storage farms with 100+MWh capacity at costs below $280/kWh.
Technological advancements are dramatically improving solar storage container performance while reducing costs. Next-generation thermal management systems maintain optimal operating temperatures with 40% less energy consumption, extending battery lifespan to 15+ years. Standardized plug-and-play designs have reduced installation costs from $80/kWh to $45/kWh since 2023. Smart integration features now allow multiple containers to operate as coordinated virtual power plants, increasing revenue potential by 25% through peak shaving and grid services. Safety innovations including multi-stage fire suppression and gas detection systems have reduced insurance premiums by 30% for container-based projects. New modular designs enable capacity expansion through simple container additions at just $210/kWh for incremental capacity. These innovations have improved ROI significantly, with commercial projects typically achieving payback in 4-7 years depending on local electricity rates and incentive programs. 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.
