TerraFlow Energy is a pioneering energy storage company headquartered in Katy, Texas, with additional facilities in Bellville, Texas. Focused on advancing grid-scale energy storage, the company specializes in next-generation flow battery technology designed to provide sustainable, long-duration storage solutions for utilities, large-scale power users, and renewable energy projects. Unlike conventional lithium-ion systems, TerraFlow’s flow batteries leverage non-flammable, water-based electrolytes and domestically sourced materials to deliver unmatched safety, efficiency, and longevity.
Battery Technology
TerraFlow Energy’s core innovation lies in its advanced organic flow battery technology, engineered to overcome limitations of traditional lithium-ion systems. The batteries use a water-based, non-toxic electrolyte formulation to eliminate risks of thermal runaway and combustion, ensuring safer operation. Unlike lithium-ion cells, which degrade with deep discharge, TerraFlow’s flow batteries maintain efficiency over extended cycles—up to 20,000–40,000 cycles—while retaining more than 90% of their capacity over a 20+ year lifespan. The design prioritizes sustainability through the use of abundant, organically sourced materials and a carbon-neutral manufacturing process powered entirely by solar energy.
The system’s scalability is a key advantage, ranging from 1 MW to 10 MW configurations, adaptable to applications such as grid stabilization, renewable energy integration, and industrial energy resilience. TerraFlow’s batteries also avoid the need for supplementary gas, reduce maintenance costs, and feature rapid response times to support dynamic grid demands. A proprietary hydraulic management system optimizes fluid dynamics and controls, while redundancy features ensure fail-safe operation even under extreme conditions. By addressing the energy sector’s challenges—cost, safety, and environmental impact—TerraFlow’s flow batteries position large-scale energy storage as a viable backbone for modernizing grid infrastructure.
Recent Projects
In early 2025, TerraFlow made significant strides in advancing its technology. In March, the company launched a 50kW Sandbox Environment to accelerate development of flow battery stack configurations, hydraulic management systems, and DC infrastructure controls. This testing platform allows real-world evaluation of system efficiency and scalability while refining control algorithms. Building on this, it plans to deploy a 1-megawatt (MW) storage system in 2025, demonstrating its ability to scale solutions for utilities and industrial clients.
Investors
TerraFlow Energy has established strategic partnerships to drive growth, including its collaboration with Pneumatic & Hydraulic Co. (P&H), which involves joint engineering efforts and equity stake integration. Additional investors remain undisclosed.
