H2

The business model centers on the production and supply of Vanadium Redox Flow Batteries (VRFB), a technology that utilizes chemical reduction-oxidation processes to store and generate electricity. H2, Inc. provides these systems to address the increasing global demand for large-scale electricity storage, which is driven by the growth of renewable energies like solar and wind power. The company has positioned itself to serve the utility-scale and long-duration energy storage markets.

H2's flagship product line is the EnerFLOW® series of energy storage systems, which are based on its proprietary flow battery technologies. These systems, such as the EnerFLOW® 510 and EnerFLOW® 640, are engineered to be scalable up to hundreds of megawatt-hours, making them suitable for large grid applications. The core benefits of their VRFB technology include scalability in power and energy, long operational life, and environmental friendliness. H2, Inc. has achieved significant milestones, including becoming the first to commercially deploy a VRFB in South Korea and securing an 8.8MWh project in Spain. In 2023, the company expanded its production capabilities by opening the 'K1 Plant' in South Korea, boasting an annual production capacity of 330MWh, one of the largest for VRFBs globally. This expansion supports its projects, including a 20MWh VRFB deployment in California.
