Gravity Power is raising funds to advance the commercialization of its long-duration, grid-connected energy storage technology designed to support the widespread adoption of renewable energy. Their system uses hydraulic lifting and descending of an underground piston coupled with a conventional hydroelectric powerhouse to store and re-generate electricity, offering low costs, high efficiency, minimal environmental impact, and ease of siting. The company holds four patents across 20 countries and plans to license its technology while providing technical support to electric utilities, power producers, and transmission companies. Gravity Power aims to address the limitations of traditional pumped storage hydroelectric systems, which dominate the market but face significant environmental and regulatory challenges.
The primary use of funds is to complete detailed engineering work, prove critical components like seals, construct a pilot plant, and prepare for commercial sales. Gravity Power’s business model focuses on licensing and partnerships with engineering firms and utilities worldwide. The company intends to capitalize on the rapidly growing demand for long-duration energy storage, driven by increased reliance on renewable energy sources like wind and solar. They have established strategic partnerships with industry leaders and are positioned to offer energy storage solutions that are environmentally benign, cost-effective, and scalable. The fundraising will support their goal of having multiple commercial projects under construction within five years, enabling significant contributions toward global grid decarbonization.
Company Info
Gravity Power develops and licenses patented long-duration grid-connected energy storage technology based on hydraulic piston systems.
Gravity Power is a pre-revenue corporation specializing in long-duration, grid-connected electrical energy storage technology. The company’s primary business model focuses on licensing its proprietary energy storage solutions and providing technical support to electric load-serving entities, independent power producers, transmission companies, and similar stakeholders worldwide. Gravity Power’s technology is based on a hydraulic system that lifts and descends an underground piston, combined with a conventional hydroelectric powerhouse, to store and regenerate electricity. The company positions its offering as having key advantages such as low levelized cost, high efficiency, minimal environmental impact, and ease of siting, supported by patent protection in 20 countries.
Gravity Power operates in a competitive industry dominated by legacy technologies like pumped storage hydroelectric systems and lithium-ion batteries. However, it differentiates itself by targeting the long-duration energy storage segment (4-16 hours), which is critical for daily generation shifting necessary for grid decarbonization. The company has completed basic engineering, secured intellectual property rights, and is working toward pilot plant construction and commercial deployment. Its roadmap includes offering plants with capacities ranging from 200 MWh to over 10,000 MWh and aims to engage with large-scale engineering and construction firms to deploy its technology globally. Gravity Power holds four key patents and has a strategy focused on capturing a significant share of the projected $1 trillion global energy storage market by 2040.
